Learnt so much from you John! I once wanted a caravan, now? I rent them from a website, delivered to site, clean, and none of issues that relate to towing, maintenance nor any of the costs of purchasing one.
I particularly enjoy the spelling, punctuation and grammar corrections. I have tried to explain to many people over the years, why in science, engineering and medicine, we need an accurate language. I hope that this comment measures up to your standards.

Careful, John - a good friend of mine was a aeronautics and avionics engineer employed by a major airline primarily as a systems fault finder. He was also almost dyslexic. When he retired from that frenetic work environment he esablished a very successful air conditioning and ventilation consultancy. His saving graces were a great memory, quick mind and an ability to recognise his shortcomings and to seek assistance from qualified others when needed. Readin', 'ritin' an' 'rithmatic abilities are a huge advantage, but not essential where other capabilities are available to compensate for shortcomings in those attributes.
My father (Dutch) was freelance mister fix it, English his second language, stuttered a lot because of frustration, but fuck me could he fix shit. Qantas had a case to case interference fit on a gas turbine compressor module (jt9-747), , without outside interference, he said in about 2 minutes it,lol be good. At that moment with a hefty soft face blow, an almighty snap was to be heard. Mission accomplished without damage. Pure genius
I feel that this is an anomaly. It’s a fair assumption to make that if you can’t type a simple sentence with correct spelling and grammar, you are likely also sub par in all areas of intelligence and education. There’s a reason doctors , engineers, and scientists can all read and write.
@@adventuretimephotos2423 What you 'feel' is irrelevant, and your 'fair assumption' is based on narrow thinking. There have been, as I wrote previously, several cases of brilliant practical work being conducted by people with literacy difficulties and many more in areas of administration and creativity who have numeracy shortcomings. Sir Richard Branson is dyslexic, for example.
John doing the job of my yr11 physics teacher, without putting me to sleep. Too bad modern teaching is hostile to old men, John would be the school teacher everyone remembers 30 years later.

I’d also like to point out education and intelligence are not the same thing.
Those last comments were spot on. In 2020 we were travelling at 80km/h and were hit head on. The two people in the car that hit us were killed, their car only had one airbag that failed to deploy. According to the doctors, we came very close to being killed as well but thankfully every one of the safety devices fitted to our car deployed. I doubt there was even much for the wreckers to use as the damage to our ute was so bad I had to be cut out of the wreck, the engine and transmission were pushed back under the car and even the rear quarters were crumpled above the wheel arches. This is where that split second timing you mentioned is so critical and is one of the reasons, as mentioned in previous comments, I will never fit a bull bar to our replacement car, a Land Cruiser. Having a relatively minor accident that deployed the airbags is irrelevant because it doesn’t mean they deployed at precisely the right time. At 80km/h I would suggest that the deployment comes down to 100ths of a second to be of maximum benefit. Cheers Stuart.

Many diesels employ piston cooling in the form of oil squirters aimed at the underside of the piston hoseing oil like a fire hose under pressure. The underside of the piton is also specially grooved to spread this oil over the entire crown. This applies to all heavy diesel engines and many light diesels.
On Bullbars.. it seems to me that a significant aspect of their liklihood to worsen the effects of collisions is that they generally raise the height of an impact. If you run a commodor into a comodore they will hit "bumper to bumper", but..replace one of them with the 4x4 with the lift kit and Bullbars, and now the Commador goes under, and the Bullbar is around head height. If your unlucky enough to be "T boned" it might be that the Airbag sensors are not triggered, and theres just side window glass between your melon and the heavy guage Bullbar. I am sure I have heard some clain that accidents involving 4x4 are.some order of magnitude more likely to involve serious injury. Also, some ppl cite "greater safety" as a reason to purchase a large vehicle.. seems to me that the safety thing is somewhat one sided! If you smash a 1 tonne vehicle into a 2 tomme vehicle surely the lighter.on will catch more damage!

I thoroughly enjoyed this John. Stewie is certainly the gift that keeps on giving. Was he confusing the word accelerator with accelerometer by any chance?
If you want to fit a bull bar for either a new or used car registered in NSW, it must comply with the ‘Technical Specification: Requirements for vehicle frontal protections systems fitted to light vehicles’.
Hi John, I always enjoy your banter, very amusing. On the subject of bull bars, I found this interesting warning sticker inside my Toyota owners manual and also inside the glove box, it says the following; Warning: Toyota strongly recommends: If you fit a Bull Bar, fit a a Toyota Genuine Accessory Bull Bar specified or approved for this exact model and grade. Toyota warns: (1) A non-Genuine Accessory Bull Bar; (2) A Toyota Genuine Accessory Bull Bar; or (3) An attachment to the front of the vehicle or Bull Bar (eg. winch, tow bar or other rigid structure) not specified or approved for this exact model and grade may: (1) Reduce occupant safety (2) Result in non-compliance with ADR 69/00 Frontal Impact Requirements: and (3) Interfere with proper operation of the SRS Air Bag. So I have a genuine Toyota accessory bull bar fitted with no other items attached to it. That is to say no spot lights, no winch etc. Where I get confused is that they (they = the faceless men of greed) say fit a Toyota genuine bull bar, then the fitment of the said genuine article is listed in item 2 of the warning. On the one hand I feel confident that the genuine accessory won't interfere with SRS deployment, then on the other hand it seems Toyota have provided a loop hole for themselves. At least I don't have an ARB (ARB = Arsehole Robbing Bastards) bull bar fitted.
Holly mackerel John 😂 Did you get up on the wrong side of the bed this morning? 🤣 Locked and loaded, firing on all cylinders and taking no prisoners. Awesome stuff 👍🏼
When the EGTs started to creep towards 900 degrees C, that is when we started to worry about potential damage to the vanes of the variable geometry turbo. No piston damage at this point. No cylinder head damage. But the turbo didn’t love it. This is in 1.5L Mazda2 Skyactiv Diesel engines we race. All-alloy engines, standard internals…
@John Cadogan the Mr T version of the ideal gas law is a valid version with only one reliable use I know of. As a third year engineering student I was taught this with R being converted to mass using the average molar mass of air. It was only used for air cycles like the Brayton cycle. So it's a valid, but not a general, expression of the law. It didn't seem to matter what version I used, I was frantically working through unit calculations to make sure I was using the right formula and gas constant every assignment and exam. It's a good formative experience for every engineer to check their work!
English dictionaries tend to document the meanings of words according to their popular usage. (Unlike French dictionaries, I gather, that tend to be more proscriptive). There can be a problem with looking up the definition of a scientific terms in an English dictionary, in that popular usage may differ from the definition used by scientists. ("Evolution" being a case in point). However, with the term "thermodynamics", there is a big clue in the name itself. The "thermo" part means (somewhat uncontroversially, I would think) heat. The term "dynamics" tends to relate to systems in motion or undergoing change. (Although I will concede that etymologically it comes from a Greek word meaning power). If scientists were restricting their study of heat flow, work, temperature etc to systems in equilibrium, I would have thought they would have called it something like "thermostatics".
Dear John, love your work. Your desire for more hate mail should be rewarded shortly. Constant laughter from your entertaining portrayals pleases me. Then, disappointment with my fellow man's understanding of basic principals of their education, sadly distresses me. Malcolm, F. N. Queensland.
You have a captive audience here John - great to have some balance between the two hemispheres - one for the everyday engineering lectures and the other with passion for the opposite gender - girls and later women were a mystery to me during my courting years and still remain so into my senior years 🙃 - I have an avionics background and a bit nerdy where I would give lectures on the Apollo Space program in the early 70’s in high school VIC - my science teacher loved it as I scribbled jet propulsion figures and lunar landing procedures on the blackboard but I eventually realised I’d lost my main audience when I could hear snoring behind me - viva le Subaru.
from what I understand, gasoline doesn't burn long enough and therefore the pressure of the event only lasts maybe a quarter of the downstroke instead of half way (90 past tdc) where the leverage of the mechanics are maximized (and past that risk of breakage increases); this is not the only reason, but one of the reasons why nitromethane is used in the drag cars and tractor pulls, it burns slower. If I listened to them correctly (and they were correct), it also makes their exhaust that loud and when they get it wrong and too much hasn't burned off towards the end, you get quite a visual spectacle when the rest of it ignites and helps divorce parts of the block from itself with vigor and excitement. (so if you could find a way to make the ignition event with gasoline to provide useful pressure against the piston head up to 90 degrees past top dead center; you would get more power which I will assume could also lead to better overall efficiency and fuel mileage by intelligent engineers) and if I've completely misunderstood, please inform :)
My last car was cheap because the previous owner spent several months arguing with the council to get his repairs paid for by them due to him driving over a large pot hole in the road. He ended up buying another car and got rid of the damaged one cheap. The pot hole destroyed the side wall of the front tyre and took a chunk out of the wheel rim and left the same side rear tyre with a large bulge in the side. The shock was severe enough to deploy the driver's seat airbag. Maybe you could explain why in the event of an airbag 'going off' Seat, in their wisdom, decided it would be a hoot to switch off the power to the electric power steering? The sane reason behind this eludes me! It was a 2005 Seat Ibiza.
One of MY favourite things to (attempt) to explain the phenomenon you have so eloquently described is the Candle theory, IE would you suffer a significant burn if you placed your palm over the flame of a lit candle, and why then doesn't then the candle (wax) just melt away to nothing given the heat of the flame is MUCH higher than the melting point of the candle's wax.
My daughter has just got her drivers licence. How about a video or two on very basic maintenance/safety, such as why you don't take the radiator cap off when the engine is hot, and why you wait a bit to test the oil level on the dipstick after turning the engine off? Kids might be more willing to listen to you than their parents.
How about a radiator cap that COULDN'T be removed until a safer coolant temperature was reached? I reckon that would be pretty easy to engineer? Maybe some up-market cars have this already?
@@herohoistsaustralia4502 I don't want or need that. And there are enough stupid people in the world already - I say no further measures to preserve them and save them from themselves.
Thank you - again - for another enlightening and highly amusing post. Honestly, I don't know which I enjoy more; being enlightened/educated on subjects that my education didn't stress (Civil Engineer), or listening to the... bloviating of the unwashed/uneducated people who presume to correct you. Honestly; I thought the modern American education system was bad, but... wow. And, those are the ones who actually manage to post something successfully on the Internet... Anyhow, keep up the good work...👍👍
John, quite apart from your casting your pearls of knowledge, largely before swine so it would seem, what makes your output so enjoyable to watch is your comic genius in these episodes about the comments you receive. Please keep it up as these are dark days in the UK and anything that makes us chuckle is highly valuable..
JC love your work perhaps some of your UA-cam followers should stick to reading the Woman's weekly subscription. Thank you for making sense of the bull shit.
Put another way, the heat can’t transfer into the body of the piston as fast as the piston is moving away from the site of combustion. The only way that he can really transfer the piston is via the radiant heat.
Never mind about whether bullbars help/hinder the occupants of the vehicle to which it is fitted, think about the potential extra damage they cause to whatever they hit. Imagine whichever 4WD crew cab ute you choose with a bullbar on it t-boning a Corolla with your Mrs and kids in it. What extra damage do you reckon that's going to do to the Corolla and your family? I'm sure they'll be comforted knowing that old mate in his Dingo Piss Creek Special feels more protected whilst they see as their lives flash before their eyes the shiny alloy bar coming for them at head height.
Regarding Bull Bars, facts accepted. Given the dangers they present suppose you did a redesign to work with everything else in protecting the occupants. Imagine a very light bar that collapses more easily, so hitting a roo might turn your bar into a throw away job. Of course a bull bar redesign might end up not being dangerous but completely useless for anything except being eye candy.
Apples and Oranges Both fruit. Both are round. Both around the same size. Both grow on trees. Both have great juice. They do have different names and taste different. He's right it is similar to comparing the two.
This and the related video were great John! A few things could be going on with the Triton/Hilux comparison. (1) Triton may be doing more work even at the same speed/weight/load up the hill due to aerodynamics and rolling resistance difference - more work, more power, more heat. IIRC drag is proportional to velocity squared? (2) Even if they are doing the same work, a hilux may be more thermally efficient in that operating range e.g. Work to the wheels vs fuel burnt. Less fuel burnt, less heat. (3) They may both be doing the same work and have same thermal efficiency but the hilux may just have a larger cooling system but as you said with 20 to 30 degrees safety margin who cares? You could even argue that the Triton's cooling system is a more optimal design - not over engineered. Really interesting topic!
It's just John trying to blind you with science again, Toyota Engine is larger and has a lower turbo boost so there is lower cylinder temperature, Mitsubishi runs a higher compression from a higher boost which creates a lot of heat at the expense of work done.
Something else to keep in mind about the Pistons in diesels the combustion face of the Piston is made out of a dissembler metal. But this is all moot because if you start your engine and let it sit there for 20 or 30 minutes it doesn't stop running because the engine failed.
Whenever I watch these videos I always hope that one day I too can make a comment that is unhinged enough that John can roast me too. I'm still chasing that dream 😐
I have got dramatically close but never a full blown roasting, of course I would be far too embarrassed were I to suggest a link between ABS and airbag deployment.
Piston crowns and skirt areas above 1st compression ring are often coated with a thin layer of very low heat convection material. A bit like a heat shield. Also it's common in diesels to have oil jets continously dousing the underside of the piston crown with relatively cool oil.
I always thought a real world example of the latent heat process and a demonstration in general of thermo dynamics ,conservation of energy, was the hand driers in a public toilet. Ever notices the air is always cold at the beginning of use ? and then heat up as the said hands dry? The energy in the stream is diverted to changing the sate of the water from liquid to gas rather transferred to the skin and nerves in your hands.
Bullbars are just expensive, heavy, painted or highly polished pieces of garnish mounted to the front of the car. Of course they are going to affect the deployment of air bags at the maximally optimum time. The risk of animal strikes disabling the vehicle can be best handled by administrative controls like not driving at dawn, dusk or night, and slowly down in conditions where a clear view of the road ahead is not available. If I was forced to own a bullbar it would be the ARB smart bar made of engineering plastic (ARB bought out the original company who first bought it to market). Relatively light and elastically absorbs the energy of the strike. The fact that one sees so few smart bars shows that most bullbar owners are the opposite. I have concerns with seat covers affecting side airbags that is why I went to seat cover inserts. Yeah, they all proudly state airbag compatible stitching, but again the presence of the side seam of the cover must affect the timing of the side airbag deployment. I have a dashmat because I live in Queensland but I have visions when I'm a passenger of the dashmat walloping me in the head should the airbag deploy. I'd get rid of it if I could.
Thank you for a very informative contribution. I was under no illusions as to the potential liabilities of fitting a bull bar on a "modern" vehicle, but I had not once stopped to consider the potential hazards associated with dash mats and car seat covers, the latter two of which I have. Food for thought, cheers.
OK that heat transfer, not thermodynamic caught me off guard... I have exceeded the face-palm safety limit with the whole new level of spectacular specialist... I missed my own forehead and have a rapidly darkening black eye, this isn't the issue, but that is nobody is going to believe me about who did it.
After hearing Davo's hypothesis about the Triton working harder than the Hilux (starts 16:58), and you gently correcting him by rightfully stating that both vehicles' engines would generate the same amount of power to ascend the hypothetical hill ceteris paribus, my inference is that what Davo actually means is that as a percentage of their respective overall power outputs, the Triton is running closer to its limit than the Hilux. I'm not suggesting that Davo's hypothesis is correct, nor am I suggesting that my interpretation is anything other than fodder for the next I Can't Believe It's Not Nut Fest Friday. However it *is* the sort of thing older beard-strokers tend to say when claiming that small engines wear out quicker than large engines in the context of motor vehicles.
The Hilux may simply be more thermally efficient at the particular engine speed and load to produce the same power too. It may just have a larger capacity cooling system which reduces the rate of rise of temperature. There are so many variables.
Tone, I was thinking the same thing. Perhaps the original comment was regarding the comparison of one's capacity to do work compared with that of the other. The two ideas are conflated and the resulting comment comes across as uneducated. Rather, it's an example of bad communication.
I love watching this type of educational footage. Cheers me up before going to work the following day. Their is a plastic bull bar on the market that trumpets the fact that it is the only one that can legally be used in Europe. I have no idea if it is true.
True, the EU and UK have to have plastic bull bars because of pedestrian safety rules. Although I think if you are hit by any pickup truck or large SUV you aren't going to get up and walk away.
Part 1: I think the commenter may have been a bit confused about exhaust temp and fuel mixture (Air fuel ratio) :) > Thanks, that was actually funny :)
There are multiple sensors that determine in an airbag deploys and it isn't a straightforward impact = deployment equation. I was in a Corolla hit by a drunk. My car rolled and airbags deployed. I walked away from that crash so they obviously weren't necessary. The same is true for a Cherokee that git hit and shoved in a ditch. No deployment and no injury.
@@badgerpa9 Are you trying to say that they would be allowed to past the crash test with one vehicle and then sell a vehicle with different parts fitted that no longer past said crash tests?
@@stusue9733 You pass or fail a test, past as in the past you may have passed a test. You are using the wrong word. You may have had breakfast in the past and someone passed you the salt. If it passed the crash test yesterday, it passed the test in the past.
Hi John, loving you videos mate, keep up the good work! One question regarding bullbars though. What about genuine bullbars fitted at the dealership before delivery is taken? Would getting one of these also compromise the effectiveness of the airbags?
I think people forget the air around them is a fluid because they conflate the meanings of the words 'fluid' and 'liquid'; at least that is my strongman argument for them.
I've learnt more about physics from you John than from my boring as batshit science teacher at high school many moons ago. I'm certain he could bore an arsehole in a wooden horse even today. On another note. I still struggle with the caravan thing. They make absolutely no sense to me. There's nothing pleasurable about them, they don't measure up on the financial side either.
Hey John, thanks for the videos, very informative. Back in the old days we would consider the temperature gauge to indicate cooling system health. If the needle is in the 'usual spot' then all good under the hood. But if it moved off that spot then start to panic because something catastrophic has happened (pump failure, water leak, thermostat, etc.). I wonder if this outdated attitude was part of the supposed shortcomings of the Triton cooling system. Also, could this attitude be a consideration by Toyota engineers in designing the cooling system of the Hilux? As in, oversize the entire system so that the temperature needle never moves to ensure drivers continue to believe the "Unbreakable" line?...
Toyota just calibrates the temp gauge to be in the ‘normal’ spot between an enormous temperature range. Like 60-110 degrees C or something so that no one knows if it’s getting hot or running a little cool. They’ve done it like this forever
Ever seen the movie Idiocracy? (I only saw a little bit before I ran away). It's happening. Comments, flat earth, Kardashians, wokes, genders, the list goes on. I'm sad. Beer o'clock I reckon
Love your videos even though some like today were just going right over my head. I do not understand why people have to question you when you have sat an engineer course and years experience as a motoring reviewer. Me I just like to know what you think of this car and that one at I think is a none bias base. Keep up the great work and look forward to the next video.
16:29 into the video: "Einstein was not a caravaner". Right! He was a boater. He owned a sailing boat in Germany that got designed by himself to fit in all the smal channels in Berlin. It got built in Kiel and paid by his friends Dr. Anschütz (inventor of the fly wheel compass after reading Einsteins specific theory of relativity) and Dr. Hell (inventor of the offset printing mashine after reading Einsteins blablabla - you got it). Unfortunately the Nazies made Einstein to leave Berlin and Germany in the early 1930th and he lost his boat. Yes, he never was a caravaner. I do know some smart guys having PHDs in science like engineering, physics, mathematic, geology and so on and some own a boat or n RV but none of them is a caravaner. My cousin is an engineer and does own a caravan. She bought a used one and put it in the backyard of her house. There was no way, she said, to get cheaper a well equiped guest house then to buy a high end caravan on the used marked. But this caravan only drove once in her posseccion: from the seller's place to her real estate. I don't recall any scientist driving around with a caravan - except bolted on the back of an old 4x4 or 6x6 or 8x8 truck to create an fully functional off road RV the cheap way. And by truck it is meant a propper truck as in you do need to get a truck driver's licence to be allowed to drive it on a public road. Scientists are no caravaners and in reverse caravaners have no clue about the deep water that comes with the to pretend to be shallow at the first glance word science. Caravaners are no scientists and scientist are no caravaners.
Maybe pedestrians should walk somewhere other than the path of traffic? You can call it a sidewalk, shoulder, or pathway, and you can have designated areas called crosswalks for when they cross the paths for everyone else? Has Europe tried that yet?
@Noah E Full of lame brains here in the UK, many also get hit by trains, they run on rails and are painted bright yellow at the front , can't be easy because on average they run 10 minutes late so they must have to wait . Don't see a great deal of difference between bull bars , motorcycles and lorrys. Speed is the main factor in my opinion.
Don't alloy pistons allow you to run higher chamber temps than cast iron pistons? much to the surprise of the people around when alloy pistons were first made.
Interesting comment by the person that said the Hilux has more power and torque, thus it's not working as hard...What if the Triton is near flat foot acceleration (wot) to go up the hill at the same speed as the Hilux, whilst the Hilux is just at half throttle? The Triton will definitely be working harder than the Hilux, hence the higher coolant temperature.

I love the Beer Garden, I know you put them all out as a podcast but I find half of them crash my podcast player. Never gets old in any case, always learn something. Thanks John.
Thank fuck I had great science and maths teachers.
I sadly didn't have a great English teacher. However, I have made many improvements in how I write and speak.
And to top that off, I enjoy learning so much I have never stopped.
Never stop learning, people.
I failed School Certificate English in '87 - 44%. Yet I despair at the state of modern written communications. That's how far standards have fallen.
Thank fuck we can say fuck in this fuckin comment fuckin section.
@@TonyRuleTony, I must agree with you. Sadly, some native speakers are so complacent that they expect the reader to "just understand" all their lazily composed prose; despite all its spelling and grammatical errors, confused syntax and misused words.
@@attilajuhasz2526 Some even have the gall to claim they knew the errors were made but, since it's an informal forum, they just didn't bother to write properly. As if anyone's going to believe they actually made an effort to write poorly, when they could have just effortlessly done that which they claim to know.

Critical thinking, logic and science, providing the answers as always. Two non-emoji thumbs up from an ex-science teacher and non caravaner who really appreciates your work.
You should get a sponsorship from Grammarly John, seems like it would be helpful to some of your viewers.
Good timing, just knocked off and needed a good video to unwind to
Pleased to be of use...

So looking forward to this.
Re: Bull Bars, BHP did some crash testing of them. I can point you at a report that came out of it. BHP stopped fitting bars to vehicles as a result.
That would be interesting: john@autoexpert.com.au
I watch your videos and love the way you explain everything, I wasn't too passionate about mechanical engineering but I kinda regret studying civil engineering after starting to watch your videos. Also, I would like to thank you as I have learnt so much from your channel ( both English day to day language as I'm still learning, and physics).
Keep up the good work John 👍
I thoroughly enjoyed this John. Stewie is certainly the gift that keeps on giving. Was he confusing the word accelerator with accelerometer by any chance?
We are not sure Jean but do let us know if he asks you for an explanation of what he wrote!!!!
One would hope.
Accellent presentation.
If you want to fit a bull bar for either a new or used car
registered in NSW, it must comply with the ‘Technical
Specification: Requirements for vehicle frontal protections
systems fitted to light vehicles’.
You’re a good guy John. Deep down.
Hi John, I always enjoy your banter, very amusing. On the subject of bull bars, I found this interesting warning sticker inside my Toyota owners manual and also inside the glove box, it says the following;
Warning: Toyota strongly recommends:
If you fit a Bull Bar, fit a a Toyota Genuine Accessory Bull Bar specified or approved for this exact model and grade.
Toyota warns:
(1) A non-Genuine Accessory Bull Bar;
(2) A Toyota Genuine Accessory Bull Bar; or
(3) An attachment to the front of the vehicle or Bull Bar (eg. winch, tow bar or other rigid structure)
not specified or approved for this exact model and grade may:
(1) Reduce occupant safety
(2) Result in non-compliance with ADR 69/00 Frontal Impact Requirements: and
(3) Interfere with proper operation of the SRS Air Bag.
So I have a genuine Toyota accessory bull bar fitted with no other items attached to it. That is to say no spot lights, no winch etc. Where I get confused is that they (they = the faceless men of greed) say fit a Toyota genuine bull bar, then the fitment of the said genuine article is listed in item 2 of the warning. On the one hand I feel confident that the genuine accessory won't interfere with SRS deployment, then on the other hand it seems Toyota have provided a loop hole for themselves. At least I don't have an ARB (ARB = Arsehole Robbing Bastards) bull bar fitted.
Three pen taps,two paper scrunching,one paper throw and dunk,video approved,thanks John,click.
Holly mackerel John 😂 Did you get up on the wrong side of the bed this morning? 🤣 Locked and loaded, firing on all cylinders and taking no prisoners. Awesome stuff 👍🏼
This has been mentioned in the post by GB Sailing. John has also made a comment re the same.
The turbo temp in my 600 Cummins gets up to over 650c, and that never melted a piston in 2 million kms
This and FullBoost are the best feedback sessions on UA-cam
When the EGTs started to creep towards 900 degrees C, that is when we started to worry about potential damage to the vanes of the variable geometry turbo. No piston damage at this point. No cylinder head damage. But the turbo didn’t love it.
This is in 1.5L Mazda2 Skyactiv Diesel engines we race. All-alloy engines, standard internals…
@John Cadogan the Mr T version of the ideal gas law is a valid version with only one reliable use I know of. As a third year engineering student I was taught this with R being converted to mass using the average molar mass of air. It was only used for air cycles like the Brayton cycle.
So it's a valid, but not a general, expression of the law. It didn't seem to matter what version I used, I was frantically working through unit calculations to make sure I was using the right formula and gas constant every assignment and exam. It's a good formative experience for every engineer to check their work!
Maybe. However, these calculations pertain to gases, not liquids.
@@attilajuhasz2526 that remains true
English dictionaries tend to document the meanings of words according to their popular usage. (Unlike French dictionaries, I gather, that tend to be more proscriptive). There can be a problem with looking up the definition of a scientific terms in an English dictionary, in that popular usage may differ from the definition used by scientists. ("Evolution" being a case in point).
However, with the term "thermodynamics", there is a big clue in the name itself. The "thermo" part means (somewhat uncontroversially, I would think) heat. The term "dynamics" tends to relate to systems in motion or undergoing change. (Although I will concede that etymologically it comes from a Greek word meaning power).
If scientists were restricting their study of heat flow, work, temperature etc to systems in equilibrium, I would have thought they would have called it something like "thermostatics".
Dear John,
love your work. Your desire for more hate mail should be rewarded shortly. Constant laughter from your entertaining portrayals pleases me. Then, disappointment with my fellow man's understanding of basic principals of their education, sadly distresses me.

You have a captive audience here John - great to have some balance between the two hemispheres - one for the everyday engineering lectures and the other with passion for the opposite gender - girls and later women were a mystery to me during my courting years and still remain so into my senior years 🙃 - I have an avionics background and a bit nerdy where I would give lectures on the Apollo Space program in the early 70’s in high school VIC - my science teacher loved it as I scribbled jet propulsion figures and lunar landing procedures on the blackboard but I eventually realised I’d lost my main audience when I could hear snoring behind me - viva le Subaru.
at the end of the day there is no substitute for cubic inches....................oh! and block strength
"We all get the same vote". Best statement on the internet for 2023. I don't believe it can be bettered. (In context)
from what I understand, gasoline doesn't burn long enough and therefore the pressure of the event only lasts maybe a quarter of the downstroke instead of half way (90 past tdc) where the leverage of the mechanics are maximized (and past that risk of breakage increases); this is not the only reason, but one of the reasons why nitromethane is used in the drag cars and tractor pulls, it burns slower. If I listened to them correctly (and they were correct), it also makes their exhaust that loud and when they get it wrong and too much hasn't burned off towards the end, you get quite a visual spectacle when the rest of it ignites and helps divorce parts of the block from itself with vigor and excitement.
(so if you could find a way to make the ignition event with gasoline to provide useful pressure against the piston head up to 90 degrees past top dead center; you would get more power which I will assume could also lead to better overall efficiency and fuel mileage by intelligent engineers)
and if I've completely misunderstood, please inform :)
My last car was cheap because the previous owner spent several months arguing with the council to get his repairs paid for by them due to him driving over a large pot hole in the road. He ended up buying another car and got rid of the damaged one cheap. The pot hole destroyed the side wall of the front tyre and took a chunk out of the wheel rim and left the same side rear tyre with a large bulge in the side. The shock was severe enough to deploy the driver's seat airbag.
Maybe you could explain why in the event of an airbag 'going off' Seat, in their wisdom, decided it would be a hoot to switch off the power to the electric power steering? The sane reason behind this eludes me!
It was a 2005 Seat Ibiza.
One of MY favourite things to (attempt) to explain the phenomenon you have so eloquently described is the Candle theory, IE would you suffer a significant burn if you placed your palm over the flame of a lit candle, and why then doesn't then the candle (wax) just melt away to nothing given the heat of the flame is MUCH higher than the melting point of the candle's wax.
My daughter has just got her drivers licence.
How about a video or two on very basic maintenance/safety, such as why you don't take the radiator cap off when the engine is hot, and why you wait a bit to test the oil level on the dipstick after turning the engine off?
Kids might be more willing to listen to you than their parents.
I actually had to change a wheel for a nearly 60 y.o. 'man' the other week because he didn't know how. I wish I was joking.
How about a radiator cap that COULDN'T be removed until a safer coolant temperature was reached? I reckon that would be pretty easy to engineer?
Maybe some up-market cars have this already?
@@herohoistsaustralia4502 I don't want or need that. And there are enough stupid people in the world already - I say no further measures to preserve them and save them from themselves.
Thank Q. For your " Beer Garden" talks.
Thank you - again - for another enlightening and highly amusing post. Honestly, I don't know which I enjoy more; being enlightened/educated on subjects that my education didn't stress (Civil Engineer), or listening to the... bloviating of the unwashed/uneducated people who presume to correct you. Honestly; I thought the modern American education system was bad, but... wow. And, those are the ones who actually manage to post something successfully on the Internet... Anyhow, keep up the good work...👍👍
John, quite apart from your casting your pearls of knowledge, largely before swine so it would seem, what makes your output so enjoyable to watch is your comic genius in these episodes about the comments you receive. Please keep it up as these are dark days in the UK and anything that makes us chuckle is highly valuable..
JC love your work perhaps some of your UA-cam followers should stick to reading the Woman's weekly subscription. Thank you for making sense of the bull shit.
Do factory fitted bars such as Isuzu ones fitted before rego effect crash safety ?
God I love these comment rebuffs. Gold!!!
I'm glad I found your channel. I enjoy the content.
Great vid fella. Wish I had been able to understand more physics at school, but at least these help. :no emoji:
Put another way, the heat can’t transfer into the body of the piston as fast as the piston is moving away from the site of combustion. The only way that he can really transfer the piston is via the radiant heat.
Never mind about whether bullbars help/hinder the occupants of the vehicle to which it is fitted, think about the potential extra damage they cause to whatever they hit.
Imagine whichever 4WD crew cab ute you choose with a bullbar on it t-boning a Corolla with your Mrs and kids in it. What extra damage do you reckon that's going to do to the Corolla and your family? I'm sure they'll be comforted knowing that old mate in his Dingo Piss Creek Special feels more protected whilst they see as their lives flash before their eyes the shiny alloy bar coming for them at head height.
Regarding Bull Bars, facts accepted. Given the dangers they present suppose you did a redesign to work with everything else in protecting the occupants. Imagine a very light bar that collapses more easily, so hitting a roo might turn your bar into a throw away job. Of course a bull bar redesign might end up not being dangerous but completely useless for anything except being eye candy.
Apples and Oranges
Both fruit.
Both are round.
Both around the same size.
Both grow on trees.

They do have different names and taste different.
He's right it is similar to comparing the two.
This and the related video were great John! A few things could be going on with the Triton/Hilux comparison. (1) Triton may be doing more work even at the same speed/weight/load up the hill due to aerodynamics and rolling resistance difference - more work, more power, more heat. IIRC drag is proportional to velocity squared? (2) Even if they are doing the same work, a hilux may be more thermally efficient in that operating range e.g. Work to the wheels vs fuel burnt. Less fuel burnt, less heat. (3) They may both be doing the same work and have same thermal efficiency but the hilux may just have a larger cooling system but as you said with 20 to 30 degrees safety margin who cares? You could even argue that the Triton's cooling system is a more optimal design - not over engineered. Really interesting topic!
It's just John trying to blind you with science again, Toyota Engine is larger and has a lower turbo boost so there is lower cylinder temperature, Mitsubishi runs a higher compression from a higher boost which creates a lot of heat at the expense of work done.
5:50. Piston broke…..describing my life.
Where would a piss ceekian mount the winch, antennas, lights etc if they had no bullbar?
Something else to keep in mind about the Pistons in diesels the combustion face of the Piston is made out of a dissembler metal. But this is all moot because if you start your engine and let it sit there for 20 or 30 minutes it doesn't stop running because the engine failed.
How's the drugs working for ya?
Hi John, a while back you suggested a good read was Hunter S Thompson. Could you please advise the recommended title. Thanks Tony.
Hell's Angels is pretty good, but the piece I was talking about was Midnight on the Coast Highway.
Did I miss the paper scrunching ?
You forgot to allow for wind chill factor.
Surely the "dynamics" in "thermodynamics" gives away that it's not just about static heat systems?
Thanks my austrian neighbor. I like ur videos.
Whenever I watch these videos I always hope that one day I too can make a comment that is unhinged enough that John can roast me too. I'm still chasing that dream 😐
You probably don't have what it takes...
I have got dramatically close but never a full blown roasting, of course I would be far too embarrassed were I to suggest a link between ABS and airbag deployment.
Piston crowns and skirt areas above 1st compression ring are often coated with a thin layer of very low heat convection material.
A bit like a heat shield.
Also it's common in diesels to have oil jets continously dousing the underside of the piston crown with relatively cool oil.
In thought experiments it's too easy to think in terms of "static" conditions rather than "dynamic" conditions which are greatly more complex.
I always thought a real world example of the latent heat process and a demonstration in general of thermo dynamics ,conservation of energy, was the hand driers in a public toilet. Ever notices the air is always cold at the beginning of use ? and then heat up as the said hands dry? The energy in the stream is diverted to changing the sate of the water from liquid to gas rather transferred to the skin and nerves in your hands.
Bullbars are just expensive, heavy, painted or highly polished pieces of garnish mounted to the front of the car. Of course they are going to affect the deployment of air bags at the maximally optimum time. The risk of animal strikes disabling the vehicle can be best handled by administrative controls like not driving at dawn, dusk or night, and slowly down in conditions where a clear view of the road ahead is not available. If I was forced to own a bullbar it would be the ARB smart bar made of engineering plastic (ARB bought out the original company who first bought it to market). Relatively light and elastically absorbs the energy of the strike. The fact that one sees so few smart bars shows that most bullbar owners are the opposite.
I have concerns with seat covers affecting side airbags that is why I went to seat cover inserts. Yeah, they all proudly state airbag compatible stitching, but again the presence of the side seam of the cover must affect the timing of the side airbag deployment.
I have a dashmat because I live in Queensland but I have visions when I'm a passenger of the dashmat walloping me in the head should the airbag deploy. I'd get rid of it if I could.
Thank you for a very informative contribution. I was under no illusions as to the
potential liabilities of fitting a bull bar on a "modern" vehicle, but I had not once stopped to consider the potential hazards associated with dash mats and car seat covers, the latter two of which I have. Food for thought, cheers.
Bravo! Highly entertaining. I wonder if some comments are deliberately provocative in order to get your attention and response.
Some seem inexplicably stupid.
OK that heat transfer, not thermodynamic caught me off guard...
I have exceeded the face-palm safety limit with the whole new level of spectacular specialist...
I missed my own forehead and have a rapidly darkening black eye, this isn't the issue, but that is nobody is going to believe me about who did it.
I gave up facepalms several years ago. It was a 'personal safety' consideration...
It's literally right there in the word thermo(heat)dynamics(movement)
@@AutoExpertJC I thought that I had done so also...
Thankfully I just sat down the hammer I was using when you started that entry.
After hearing Davo's hypothesis about the Triton working harder than the Hilux (starts 16:58), and you gently correcting him by rightfully stating that both vehicles' engines would generate the same amount of power to ascend the hypothetical hill ceteris paribus, my inference is that what Davo actually means is that as a percentage of their respective overall power outputs, the Triton is running closer to its limit than the Hilux.
I'm not suggesting that Davo's hypothesis is correct, nor am I suggesting that my interpretation is anything other than fodder for the next I Can't Believe It's Not Nut Fest Friday. However it *is* the sort of thing older beard-strokers tend to say when claiming that small engines wear out quicker than large engines in the context of motor vehicles.
The Hilux may simply be more thermally efficient at the particular engine speed and load to produce the same power too. It may just have a larger capacity cooling system which reduces the rate of rise of temperature. There are so many variables.
It could be the Hilux is indestructible, and a triton is the dog who wants to lay up on the porch with the big mongrel Toyotas.
Tone, I was thinking the same thing. Perhaps the original comment was regarding the comparison of one's capacity to do work compared with that of the other. The two ideas are conflated and the resulting comment comes across as uneducated.
Rather, it's an example of bad communication.
I love watching this type of educational footage. Cheers me up before going to work the following day.
Their is a plastic bull bar on the market that trumpets the fact that it is the only one that can legally be used in Europe.
I have no idea if it is true.
Their, there, they're
True, the EU and UK have to have plastic bull bars because of pedestrian safety rules. Although I think if you are hit by any pickup truck or large SUV you aren't going to get up and walk away.
Slaying one subscriber at a time.
Ore maybe several.
Part 1: I think the commenter may have been a bit confused about exhaust temp and fuel mixture (Air fuel ratio) :)
>
Thanks, that was actually funny :)
Not sure about Australia, but in UK fitting a bullbar will likely cost you a ton in higher insurance costs. You might not even get insurance.
Not here
And light bars are not legal on the top of the bull-bars ( sorry roo), they must be below bonnet line.
I've seen an older Ford Ranger with a bullbar T bone another vehicle! Which caused it to roll over and the airbag never deployed.
There are multiple sensors that determine in an airbag deploys and it isn't a straightforward impact = deployment equation. I was in a Corolla hit by a drunk. My car rolled and airbags deployed. I walked away from that crash so they obviously weren't necessary. The same is true for a Cherokee that git hit and shoved in a ditch. No deployment and no injury.
I think chatgpt shall become my AE translator. ;-) Love your work.
But, after a crash, it is an Ex-celerator, as it will be of no further use.
i am full of joy knowing that i live in the land of "nuffys"
Wouldn't things like the "Front protection bar " Mitsubishi sell as an option for delivery on a new triton have to past the crash tests?
Maybe would need to pass the crash test, then it would be past the test.
@@badgerpa9 Are you trying to say that they would be allowed to past the crash test with one vehicle and then sell a vehicle with different parts fitted that no longer past said crash tests?
@@stusue9733 You pass or fail a test, past as in the past you may have passed a test. You are using the wrong word. You may have had breakfast in the past and someone passed you the salt. If it passed the crash test yesterday, it passed the test in the past.
@@badgerpa9Congratulations. You win the internet today.
@@stusue9733 Thanks I need it.
Hi John, loving you videos mate, keep up the good work! One question regarding bullbars though. What about genuine bullbars fitted at the dealership before delivery is taken? Would getting one of these also compromise the effectiveness of the airbags?
Yes. Most probably. I've never seen a manufacturer crash test a bullbar equipped vehicle.
I hate it when my transmission fluid grenades.
I think people forget the air around them is a fluid because they conflate the meanings of the words 'fluid' and 'liquid'; at least that is my strongman argument for them.
The closing of this video was "gold".

Happy the first comment you mocked was the one that annoyed me the most 👍
I've learnt more about physics from you John than from my boring as batshit science teacher at high school many moons ago. I'm certain he could bore an arsehole in a wooden horse even today. On another note. I still struggle with the caravan thing. They make absolutely no sense to me. There's nothing pleasurable about them, they don't measure up on the financial side either.
For the wooden horse I would suggest an 8mm bit.
@@rjpbof7221 yes, I'd agree. Although that would be a tight orifice. Should we double it to 16mm for good measure? That allows for extra boredom.
Carnot heat engine, seems apt :-)
Hey John, thanks for the videos, very informative. Back in the old days we would consider the temperature gauge to indicate cooling system health. If the needle is in the 'usual spot' then all good under the hood. But if it moved off that spot then start to panic because something catastrophic has happened (pump failure, water leak, thermostat, etc.). I wonder if this outdated attitude was part of the supposed shortcomings of the Triton cooling system. Also, could this attitude be a consideration by Toyota engineers in designing the cooling system of the Hilux? As in, oversize the entire system so that the temperature needle never moves to ensure drivers continue to believe the "Unbreakable" line?...
Toyota just calibrates the temp gauge to be in the ‘normal’ spot between an enormous temperature range. Like 60-110 degrees C or something so that no one knows if it’s getting hot or running a little cool. They’ve done it like this forever
Ever seen the movie Idiocracy? (I only saw a little bit before I ran away). It's happening. Comments, flat earth, Kardashians, wokes, genders, the list goes on. I'm sad. Beer o'clock I reckon
I saw something regarding Costco on a Fox news YT feed and I had to respond to it with the welcome to Costco I love you part from that movie.
Don't just give up (re beer o'clock). Whenever you get the opportunity, "shine a light" on it and criticise it intensity!
I would very much like to see ANCAP do a crash test of a vehicle with a bull bar fitted. Somehow I doubt ARB will volunteer to take part

I do not understand why people have to question you when you have sat an engineer course and years experience as a motoring reviewer. Me I just like to know what you think of this car and that one at I think is a none bias base. Keep up the great work and look forward to the next video.
Dumb question - is a “caravaner” an RVer in the states?
As Ford Fairlane, the Rock and Roll Detective, once said, “So many assholes, so few bullets.” 😂
16:29 into the video: "Einstein was not a caravaner". Right! He was a boater. He owned a sailing boat in Germany that got designed by himself to fit in all the smal channels in Berlin. It got built in Kiel and paid by his friends Dr. Anschütz (inventor of the fly wheel compass after reading Einsteins specific theory of relativity) and Dr. Hell (inventor of the offset printing mashine after reading Einsteins blablabla - you got it). Unfortunately the Nazies made Einstein to leave Berlin and Germany in the early 1930th and he lost his boat. Yes, he never was a caravaner. I do know some smart guys having PHDs in science like engineering, physics, mathematic, geology and so on and some own a boat or n RV but none of them is a caravaner. My cousin is an engineer and does own a caravan. She bought a used one and put it in the backyard of her house. There was no way, she said, to get cheaper a well equiped guest house then to buy a high end caravan on the used marked. But this caravan only drove once in her posseccion: from the seller's place to her real estate. I don't recall any scientist driving around with a caravan - except bolted on the back of an old 4x4 or 6x6 or 8x8 truck to create an fully functional off road RV the cheap way. And by truck it is meant a propper truck as in you do need to get a truck driver's licence to be allowed to drive it on a public road. Scientists are no caravaners and in reverse caravaners have no clue about the deep water that comes with the to pretend to be shallow at the first glance word science. Caravaners are no scientists and scientist are no caravaners.
Bolting thing in the front of the car should be illegal... Like it's illegal here in Europe... People walk around, stop killing them
Maybe pedestrians should walk somewhere other than the path of traffic? You can call it a sidewalk, shoulder, or pathway, and you can have designated areas called crosswalks for when they cross the paths for everyone else? Has Europe tried that yet?
@Noah E Full of lame brains here in the UK, many also get hit by trains, they run on rails and are painted bright yellow at the front , can't be easy because on average they run 10 minutes late so they must have to wait . Don't see a great deal of difference between bull bars , motorcycles and lorrys. Speed is the main factor in my opinion.

Don't alloy pistons allow you to run higher chamber temps than cast iron pistons? much to the surprise of the people around when alloy pistons were first made.
So much to enjoy
Interesting comment by the person that said the Hilux has more power and torque, thus it's not working as hard...What if the Triton is near flat foot acceleration (wot) to go up the hill at the same speed as the Hilux, whilst the Hilux is just at half throttle? The Triton will definitely be working harder than the Hilux, hence the higher coolant temperature.
Stu nicked one of Browneye's apostrophes.
