Not really much different from a petroleum engine, only that hydrogen has a lot of problems, mainly fuel tank leakage that we dont know how to fix yet.
Very accurate and clearly explained. Key to efficiency is indeed smaller engine working at good rpm range. How else do you explain great highway results (when regen braking is zero). All other explanations I have seen seem to ignore these basics.
My husband is getting a hybrid car and i was very skeptical bc i thought we needed to charge both the batter and fuel the tank which would hurt us considering theres not a lot charging station. BUT your diagram makes it easy for me to understand and feel at ease. I hope our hybrid is a series HAHA
Hey im heading into college this coming year and i really enjoy watching your videos and learning about this car stuff. I was just wondering what type of college majors would involve the type of stuff you talk about on your channel. Thanks and keep the vids coming!!
Best of luck with your education! Here's an article I wrote you'll probably find helpful: www.howdoesacarwork.com/p/should-i-become-mechanic-mechanical.html
It is well known that an ICE is most efficient within a small portion of its RPM range. What isn't as well known, is that efficiency depends more on load than RPM. For example, the ICE in a 2020 Camry Hybrid is 40% efficient at 2500 RPM and 125 lb-ft. Which is a lot of torque. It loses no more than 1% by changing +/-800 RPM, a fairly wide range. But about 15 lb-ft loses the same, and is too much for most driving. The reason smaller ICEs are more efficient is not that they are inherently so, it is that this sweet spot is closer to driving conditions. The point is that an HEV gains more efficiency by using this information, than by what this video listed. It can run closer to the sweet spot by using the battery to buffer energy. For example, at 55 mph, the Accord Hybrid (presented in another video in this channel) needs 10 to 15 HP to cruise. It splits time between running the ICE at 34 HP and 40% efficient ICE while saving more than half the energy in the battery, and EV mode. And so is about 40% to 50% more efficient.
Great presentation. One suggestion: Use a thin pointer so as not to obstruct your excellent drawing with your arm, hand, and fingers. It also makes you look very professorial.
They're all building up to this, AC motors, electric motors, batteries, all important parts of a hybrid vehicle. :) That said, it's clear that it wasn't as popular of a subject as many other topics. I'll be getting back into some non-hybrid material soon - this playlist has gone on for quite a while!
I think hybrid vehicles as a topic was good but AC motors and batteries were a bit boring as a mechanical engg view point..any way thanks for all the uploads
What I don't understand is why ICE is used to chargr batteries for Elec. motor? Aren't there loses in energy conversion process? I mean you have to convert mechanical energy to electric and than back to mechanical e. Wouldn't it be more efficient to use mechanical energy directly, and for charging batteries use only regenerative braking?
Hi Jason, really enjoy watching your videos! What's your take on the durability and longevity of hybrid batteries in terms of its replacement cost (old and future cars)? I ask because recently I had a hybrid battery replaced on my honda accord 2007 hybrid V6 at 90k miles. I had to fight a lot of unnecessary bureaucracy battles through the company and dealership to get it replaced under warranty as they wanted to charge $4000 for it. After having it replaced, I contemplated if I'd be better of owning a gas car with the absence of a hybrid component because of the insane costs of hybrid component replacement. I sensed probably in the long run, it'd be more expensive to maintain a hybrid vehicle for that reason. Cheers.
Wow, I truly enjoyed this video too. Did you ever get a response to your question? I had the same concern about hybrids as well. I wonder if its something a typical diy person can do...
Playfer The Toyota system can do series and parallel. It can deliver power to a generator and to the transmission. The system can act like a series or like a parallel or like both together at the same time.
@@andythealien1 Yes there is. The toyota prius is a series-parallel style using a power split device in the transmission. The biggest difference is a parallel system wouldn't be able to take off from a standstill using only electric, since it uses the engine and hybrid system at the same time, but a series-parallel can utilize the best of both and work independently or together.
At least from what I gathered from the video, depends on the use case. For a daily driver I'd expect series to be better but for performance a parallel system would be more effective because there isn't an in-between step for the motor to deliver power to the wheels.
Studying for my hybrid propulsion exam, speaking with my friends, a hydrogen fuel cell electric vehicle looks to be the way forward. If you look into the production of hydrogen from algae, it is able to create the hydrogen by consuming CO2 whilst producing O2 (photosynthesis). With this taken into account and the fact that hydrogen fuel cells only has a bi-product of H20, there is no carbon produced in the process (excluding the transportation of hydrogen). Was wondering if you could have an input into this? Explain any problems I am over looking, would be awesome!
I dig out all the internet and I didn't find an answer to a simple question, so you EngineeringExplained are my last hope :) Why manufacturers (like Toyota) of HEV are not making PHEV with exactly the same parts, but only with larger battery (3-5 kWh) and option to charge it at home. I'm starting from my needs and I believe many others have the same or similar needs for short (5-15 miles) trips of city driving, so no need for PHEV with 15-20 kWh battery with active cooling and strong electric motors, just the same hardware that HEV Toyotas already have it. That will make PHEV more affordable and very practical. Any idea why this is the case on the market?
Am I to understand that a Hybrid in series ill be dead if the batteries die out since the engine uses its power Not to drive the engine but to create electricity to charge the batteries so the electric motor can drive the car? if so them the best option is a paraller system is this so? your help will be much appreciated thanks
thank a lot man , perfectly explained ..first video I ran into..that guy was talking to him self and so fast that i couldnt catch any of what he was saying lol... Thanks again ,well done
From what you say the advantages seem marginal at best. I can't believe regenerative braking makes much difference especially as a city car is driven 'lightly' and stop/start applies to ICE driven cars anyway.
Can you explain the cooling system in the Prius Toyota I test drove the car and i didn't see any special gauge for it and how does it work why there's no gauge for it ? Thanks
About the Prius (latest model): it is hybrid but I can't understand what type. In the driver console it shows the ICE can send power to the generator (which consequently can recharge the battery of the electric engine), but can also send power directly to the wheels.. Now, is that a "hybrid of the types of hybrid systems that a hybrid car has"? Hope I was clear enough.. thx
It's a mix of both parallel and hybrid. I was planning on making a video of it, but the hybrid playlist wasn't very popular so I'm to different topics for now.
what i want to know is how the IC engine gets involved on the parallel one when the car finally is going at a higher speed and needs the IC engine's help. Can two separate motors both be inputting power into the transmission without the slower/weaker running motor holding back the faster/stronger moving one? if that makes any sense
What kind of hybrid are the new ones? Because i drove a new kia niro and its combustion engine charged the batteries but it could drive pure ev and it could drive with battery help for combustion engine. So is it just kind of a. HYBRID :D of both parallel and series? And thanks for the really detailed info videos
what I find funny is trains use a hybrid system that is extremely effecient. they can haul large loads for little fuel. so how about making hybrids based on that. the way a train is a hybrid is an internal combustion engine ONLY turns a generator that charges batteries only. the batteries then power the eletric motors. this makes it so when the electric motors have to work harder there is no direct need for more fuel to be used. in the automobile version the ICE could turn off when the batteries are above a certain percentage and turn on when below. it could also mean a smaller ICE as well, which means less fuel consumed
I could be wrong but I haven't heard of one that runs that way. most of the ones I hear about are the ones where the electric motor is between the engine and transmission
Finally someone who thinks the same way. I always thought that a diesel-electric drivetrain like in trains would be amazing to have in cars, may it be gas-electric, doesn't matter. And now look at that, Hyundai is giving you the choice with their new IONIQ. It's available with three drivetrains: All Electric - only uses an electric motor for propulsion, there is no internal combustion engine built in Hybrid - uses an ICE and electric motor for propulsion, the ICE helps when the electric motor doesn't have enough power or when the batteries run low Plug-in Hybrid - uses an electric motor for propulsion, but has an ICE built in to charge the battery and extend the range, the main charging comes from plugging it in in your garage. (this is kind of equivalent to diesel-electric trains, except for the charging bit)
This video may still be relevant or there may be new and different systems available. its 5yo in a very rapid development timeframe. One thing that has always intrigued me about ICE/HICE (Now 2019) and batteries and fuel cells is what sort of output do we need from a motor to generate how many Kw for Cars, Motorbikes, 4wds up to heavy units in order for them to operate successfully (current electric car outputs are not enough for the regular even urban dwelling e-car owner to make a successful road trip to the country on the w/e a very popular Australian pastime, let alone for anyone who lives in a more rural setting to be able to complete their daily klms even if its say once a month they have to more than 400km in a day but Id say its at least twice a week and so you want to own that vehicle or there will be a huge fleet of rental vehicles and a huge cost and youhave already paid a huge amount for a e-car. So my bet at the moment is Hydrogen does have a stable fuel at the moment and that right now there is no electrical system that can equal what we can make in range and keep the efficiency and regular car things like fun and accelerative potential for safety etc. So what motors, Seen Mazda rotary Skyactive and say a Klugenhiem(sic) orbital motor which is powered by supposedly many/any fuels. So whats the best operational or in testing Hybrid since you dont like to make conjecture or since say the Rotary Skyactive or Klugenhiem arent in production I know of what would be the best and how to we work out the mathematics of many kw makes enough power in a battery or fuel cell to be used by an electric motor for what application 80-100km cities sports cars, 4wds, Flying cars per KG?? The answers to life the universe and everything!! Thanks
It seems clear that as long as the oil and gas industries maintain a stranglehold on the automotive industry and innovation we will never see a truly efficient low cost alternative to internal combustion engines. I have seen so many prototype creations which looked promising but have never seen any brought to the marketplace.
Boi, thx for the video as it helped me with my oral project and for Nathan berry, I think parallel because, you can either use electricity to power the transmission or the fuel at different times so, you can maybe only use the electricity part more than the fuel(i'm not the real jake paul either lol)
There is no easy answer. There are a lot of design considerations, and not only in the Serial v. Parallel configuration. Few cars stick to one method - for example, Toyotas use both at the same time, but can be thought of as mostly parallel. But there is also a choice of the relative sizes of the motors and engines, and the configuration affects that choice. Jason mentioned that hybrids allow for smaller engines, and narrower rpm bands. But smaller engines are not _inherently_ more efficient. And rpms are not the the most important factor that determines efficiency - power is. A car might need 5 to 20 HP to maintain speed, depending on what that speed is and how heavy it is. But it might need 100 to 200 HP for "acceptable" acceleration, depending on those same factors and what you consider "acceptable." But an engine will be most efficient at around 1/5 to 1/3 of its maximum power. This will be above the power required for cruising, where most gas is used. But a lower expectation for "acceptable" will improve net efficiency, which is why smaller engines provide better efficiency. The way a hybrid gains efficiency, is that whenever it needs the engine it will try to run it closer to this optimal level of power than the car heeds. Power is sent to, or drawn from, the battery to achieve what the car needs. Starting the car moving on electric power is not the actual goal, it is just one way this is achieved. Now, to your question. The advantage of a serial hybrid is that it can use an even smaller engine, and run it at the optimum rpms _and_ power more often. The disadvantage is that it suffers more losses in converting electrical power between A/C and D/C, changing power levels, and using the battery. The advantage of a parallel (or serial-parallel, like Toyotas) hybrid that there are fewer electrical losses. The disadvantage is that they need a larger engine. This means they can only run _close_ _to_ the optimum rpm and power level, instead of at it. In terms of power, the serial hybrid will have a larger electric motor. So all else as close to equal as possible, it will accelerate to highway speeds more quickly. But it can't combine the power of the motor and engine, so it eventually loses this advantage. As examples, the Honda Accord (mainly serial) and Toyota Camry (serial-parallel) are very similar cars. The Accord Hybrid has a 143 HP engine with optimum efficiency at 34 HP, while the Camry Hybrid has a 176 HP engine with optimum efficiency around 60 HP. So it can't run optimally unless it accepts more battery losses than the Accord. The main drive motors, however, are 181 HP and 118 HP, respectively. Car&Driver says the serial hybrid Accord does 0-60 mpg in 7.1 seconds; the Camry takes 7.9. But for 50-70 mpg, the Camry wins 5.1 to 5.8. (For reasons specific to the Accord system, this was an unfair test and the Accord could probably do better.)
sir! I need to ask you a lot of questions related to hybrid cars because there are a lot of queries into my mind and i must have to make a hybrid car till 26 january. so please sir is there any other mean of communating you directly. Help me sir.. please!
With the current changes in F1 I was hoping that you could do a video on ground effect (cars) why they were banned and the advantages of it over typical methods in achieving downforce.
So, what I want to know is why is it more efficient? You use a gas engine to turn a generator....and the generator turns a motor...and there has to be a drop in efficiency when you turn motion to electricity and turn the electricity back into motion. I'm not arguing that hybrids don't work, obviously they do, their efficiency has been proven, but I want to know HOW and WHY they are so much more efficient.
What if the electric engine doesn't start (fails) does the program jump to "start combustion engine?" Then give you a warning, or diagnostic message, to "check, or service electric engine?" Then continue running on ICE, until the electric engine problem is resolved? (i.e. default to starting ICE, on startups)
In a parallel setup, how can the electric motor and the ICE simultaneously rotate the transmission without messing with the synchronisation of one another?
I am interested. Would the series hybrid really be that much more efficient than a standard car? Because aren't you using one form of energy to generate another, thus kind of eliminating much of the reason for having a hybrid in the first place? I get that the battery would help and if you could plug it in at home that would also help. I personally think Parallel makes much more sense. What do you guys think?
Diesel locomotive which is actually diesel hybrid or diesel-electric. While the diesel engine give high torque low RPM that need a lot of overdrive gear to make it spin at high RPM, and that also mean more weight. So the engine turn genertaor that then turn motor. The motor can make low RPM output to high RPM output without transmission. So in all it's more efficient. But if it's compared to parallel hybrid, I don't know.
Indra Ida Bagus Yeah I get what you are saying. Using an electric motor to drive the weight while the engine just focuses on making electricity seems like a good idea. But the problem I see is that while an electric motor is really efficient at transferring energy into movement, an engine is not. If ultimately you require the engine to turn a generator you are still dealing with an inefficient system at some point. In order to generate enough energy to supply the batteries and motor the engine would probably have to be on constantly once the electric range has ended. It that case, I reckon it would just make more sense to remove the engine and complex drive train stuff and just stuff in more batteries and extend that electric range. Or a parallel hybrid
Yeah, the electricity input for motor is a problem if you ask me. Battery is not very efficient in storing or releasing electricity. So I think the engine should be keep running to power the motor (and should be diesel engine to be more efficient). Maybe it can use auto idle and KERS for restart. But yeah.... hybrid is good but not "super" efficient. So I actually got an idea, why don't just make AWD with front wheels driven by gas engine, while rear wheels driven by motor (engine-generator-motor)... Idk will that work and get way..... more efficient than gas engine only or not, I'm still 13. =)
Yeah man Batteries suck, a few parallel hybrids are like that AWD thing I think. Mercedes Benz E-400 is a rear wheel drive hybrid...so that's cool. You certainly are on the ball for only 13 years. Good on you man :)
Hey! I am planning on doing a hybrid-electric conversion on a rear-wheel drive vehicle. Trying to brainstorm how to couple a manual RWD with an electric motor, where in the chassis it should sit and etc. I have the battery and cooling system figured out, just not sure about the motor. Can it be coupled to the rear differential? Any advice would be great, thanks!
4 year old comment, so you've probably got this figured out by now, but just in case. I've never done an electric conversion, so take this with a grain of salt, but when I looked it up in the past, the method I saw used was to attach the drive motor to the engine side of the transmission and lock the transmission in 2nd gear.
Also some fuel energy is lost to converting gas to motion to electricity to motion instead of moving the car in the first place, its just not efficient.
Left off a big one. Internal combustion dumps a lot of fuel in the engine after a stop light turns green. Electric motor does most of the work at stop lights which doesn't have huge dump a fuel into engine
sunyboy is correct. imagine my annoyance with "motor oil" for combustion engines. i work for a company that builds engines and it drives me nuts when people say "motors" when they are talking about cars. then they call themselves car guys. you don't even know what you have under your hood! a huge pet peeve of mine.
Has anybody tried to tune the ICE to run solely on hydrogen from an on demand hydrogen system? I have not had a chance to test a hydrogen generator myself yet but it seems like it would work. This would mean the vehicle is running completely on water. Do we actually have the technology to do this already but no one is doing it yet? From what I understand, the ICE can run completely on hydrogen. However it would take too long for the power to come up if you need to accelerate. But if you are just recharging batteries the system can be tuned to run at a steady RPM when recharging.
You make great videos. Always interesting and helpful. i was wondering if you could go over rust. and the best way to prevent it or seal the metals so they dont rust.
The car on the right has the wrong sized tire on, you should not mix tire sizes. Also both cars are missing front wheels, just thought i would point that out
U can't let ethanol sit or it will turn to water and if u don't have a plastic fuel tank that's treated it Will eat through the gas tank and cost more money than what it's worth
Still can't see how hybrids use less fuel. Regenerative braking amounts to so little on a long journey. Prius has over 1700 cc (not a small engine). How much does an engine use on idling? must be tiny amount.
let's not forget to mention the sorry ass tires that hybrids are equipped with that offer minimal traction, and the smaller, lighter brakes that are only installed because it's the law.
Regenerative braking can provide substantial stopping force, so smaller lighter brakes make sense. And if you don't drive aggressively (aka driving a hybrid) low rolling resistance tires will be just fine.
maybe youre looking at the wrong hybrid vehicles...there are many different styles, targeted uses and price range vehicles available...some of which can outperform high line sports cars...expanding your focus might lead to expanding your conclusion a bit...
That wouldn't be a hybrid, it would be a multi-fuel vehicle, since you can use the same engine for both fuels. The only thing that needs to change is how much fuel is injected, since you need something like 20%-30% more when burning ethanol. And this is done on the fly by the ECU. You can also run a the ignition timing a bit more aggressive on ethanol.
Can't wait to see a video on Hydrogen cars!
Not really much different from a petroleum engine, only that hydrogen has a lot of problems, mainly fuel tank leakage that we dont know how to fix yet.
10 years later, still no major update for h2 cars, because it's not practical

One thing that has always intrigued me about ICE/HICE (Now 2019) and batteries and fuel cells is what sort of output do we need from a motor to generate how many Kw for Cars, Motorbikes, 4wds up to heavy units in order for them to operate successfully (current electric car outputs are not enough for the regular even urban dwelling e-car owner to make a successful road trip to the country on the w/e a very popular Australian pastime, let alone for anyone who lives in a more rural setting to be able to complete their daily klms even if its say once a month they have to more than 400km in a day but Id say its at least twice a week and so you want to own that vehicle or there will be a huge fleet of rental vehicles and a huge cost and youhave already paid a huge amount for a e-car.
So my bet at the moment is Hydrogen does have a stable fuel at the moment and that right now there is no electrical system that can equal what we can make in range and keep the efficiency and regular car things like fun and accelerative potential for safety etc. So what motors, Seen Mazda rotary Skyactive and say a Klugenhiem(sic) orbital motor which is powered by supposedly many/any fuels. So whats the best operational or in testing Hybrid since you dont like to make conjecture or since say the Rotary Skyactive or Klugenhiem arent in production I know of what would be the best and how to we work out the mathematics of many kw makes enough power in a battery or fuel cell to be used by an electric motor for what application 80-100km cities sports cars, 4wds, Flying cars per KG?? The answers to life the universe and everything!!
Thanks

No video on power split hybrids like Prius's or similar?
in series hybrid why does the generator not generate current directly to the engine?
It seems clear that as long as the oil and gas industries maintain a stranglehold on the automotive industry and innovation we will never see a truly efficient low cost alternative to internal combustion engines. I have seen so many prototype creations which looked promising but have never seen any brought to the marketplace.
No, its because there is none.Thermodynamics rule the world.
Boi, thx for the video as it helped me with my oral project and for Nathan berry, I think parallel because, you can either use electricity to power the transmission or the fuel at different times so, you can maybe only use the electricity part more than the fuel(i'm not the real jake paul either lol)
Good day can I put CNG in the Toyota Fielder hybrid car ?????
Hey, your the dude who pranked me with Chris fix!!!
Good informative video and well explained.
So which hybrid system is the one to go for in terms of fuel economy and power output (series or parallel)?
Toyota combines both and uses a series-parallel system in most of their hybrid cars
There is no easy answer. There are a lot of design considerations, and not only in the Serial v. Parallel configuration. Few cars stick to one method - for example, Toyotas use both at the same time, but can be thought of as mostly parallel. But there is also a choice of the relative sizes of the motors and engines, and the configuration affects that choice.
Jason mentioned that hybrids allow for smaller engines, and narrower rpm bands. But smaller engines are not _inherently_ more efficient. And rpms are not the the most important factor that determines efficiency - power is. A car might need 5 to 20 HP to maintain speed, depending on what that speed is and how heavy it is. But it might need 100 to 200 HP for "acceptable" acceleration, depending on those same factors and what you consider "acceptable." But an engine will be most efficient at around 1/5 to 1/3 of its maximum power. This will be above the power required for cruising, where most gas is used. But a lower expectation for "acceptable" will improve net efficiency, which is why smaller engines provide better efficiency.
The way a hybrid gains efficiency, is that whenever it needs the engine it will try to run it closer to this optimal level of power than the car heeds. Power is sent to, or drawn from, the battery to achieve what the car needs. Starting the car moving on electric power is not the actual goal, it is just one way this is achieved.
Now, to your question. The advantage of a serial hybrid is that it can use an even smaller engine, and run it at the optimum rpms _and_ power more often. The disadvantage is that it suffers more losses in converting electrical power between A/C and D/C, changing power levels, and using the battery. The advantage of a parallel (or serial-parallel, like Toyotas) hybrid that there are fewer electrical losses. The disadvantage is that they need a larger engine. This means they can only run _close_ _to_ the optimum rpm and power level, instead of at it.
In terms of power, the serial hybrid will have a larger electric motor. So all else as close to equal as possible, it will accelerate to highway speeds more quickly. But it can't combine the power of the motor and engine, so it eventually loses this advantage.
As examples, the Honda Accord (mainly serial) and Toyota Camry (serial-parallel) are very similar cars. The Accord Hybrid has a 143 HP engine with optimum efficiency at 34 HP, while the Camry Hybrid has a 176 HP engine with optimum efficiency around 60 HP. So it can't run optimally unless it accepts more battery losses than the Accord. The main drive motors, however, are 181 HP and 118 HP, respectively. Car&Driver says the serial hybrid Accord does 0-60 mpg in 7.1 seconds; the Camry takes 7.9. But for 50-70 mpg, the Camry wins 5.1 to 5.8. (For reasons specific to the Accord system, this was an unfair test and the Accord could probably do better.)
Is there anyway way we could get a video on the difference between octane grades of gasoline and which ones are better and why?
Absolutely: Octane Rating - Explained
:)
can we have a video that shows various hybrid systems used by LMP1 (and the upcoming LMh) in WEC
Could capacitors be used in place of a large main battery for performance-based vehicles?
sir!
I need to ask you a lot of questions related to hybrid cars because there are a lot of queries into my mind and i must have to make a hybrid car till 26 january.
so please sir is there any other mean of communating you directly.
Help me sir..
please!
With the current changes in F1 I was hoping that you could do a video on ground effect (cars) why they were banned and the advantages of it over typical methods in achieving downforce.
So, what I want to know is why is it more efficient? You use a gas engine to turn a generator....and the generator turns a motor...and there has to be a drop in efficiency when you turn motion to electricity and turn the electricity back into motion. I'm not arguing that hybrids don't work, obviously they do, their efficiency has been proven, but I want to know HOW and WHY they are so much more efficient.
What if the electric engine doesn't start (fails) does the program jump to "start combustion engine?" Then give you a warning, or diagnostic message, to "check, or service electric engine?" Then continue running on ICE, until the electric engine problem is resolved?
(i.e. default to starting ICE, on startups)
Electric motors don't fail. Combustion motors do.
In a parallel setup, how can the electric motor and the ICE simultaneously rotate the transmission without messing with the synchronisation of one another?
Maybe using clutches? Idk
Dear, I want to know how it works & which km its working & which speed it covert to IC engine................
I am interested. Would the series hybrid really be that much more efficient than a standard car? Because aren't you using one form of energy to generate another, thus kind of eliminating much of the reason for having a hybrid in the first place? I get that the battery would help and if you could plug it in at home that would also help. I personally think Parallel makes much more sense. What do you guys think?
Diesel locomotive which is actually diesel hybrid or diesel-electric. While the diesel engine give high torque low RPM that need a lot of overdrive gear to make it spin at high RPM, and that also mean more weight. So the engine turn genertaor that then turn motor. The motor can make low RPM output to high RPM output without transmission. So in all it's more efficient.
But if it's compared to parallel hybrid, I don't know.
Indra Ida Bagus Yeah I get what you are saying. Using an electric motor to drive the weight while the engine just focuses on making electricity seems like a good idea. But the problem I see is that while an electric motor is really efficient at transferring energy into movement, an engine is not. If ultimately you require the engine to turn a generator you are still dealing with an inefficient system at some point. In order to generate enough energy to supply the batteries and motor the engine would probably have to be on constantly once the electric range has ended. It that case, I reckon it would just make more sense to remove the engine and complex drive train stuff and just stuff in more batteries and extend that electric range. Or a parallel hybrid
Yeah, the electricity input for motor is a problem if you ask me. Battery is not very efficient in storing or releasing electricity. So I think the engine should be keep running to power the motor (and should be diesel engine to be more efficient).
Maybe it can use auto idle and KERS for restart. But yeah.... hybrid is good but not "super" efficient.
So I actually got an idea, why don't just make AWD with front wheels driven by gas engine, while rear wheels driven by motor (engine-generator-motor)... Idk will that work and get way..... more efficient than gas engine only or not, I'm still 13. =)
Yeah man Batteries suck, a few parallel hybrids are like that AWD thing I think. Mercedes Benz E-400 is a rear wheel drive hybrid...so that's cool. You certainly are on the ball for only 13 years. Good on you man :)
What do you mean with "certainly are on the ball"?
Hey! I am planning on doing a hybrid-electric conversion on a rear-wheel drive vehicle. Trying to brainstorm how to couple a manual RWD with an electric motor, where in the chassis it should sit and etc. I have the battery and cooling system figured out, just not sure about the motor. Can it be coupled to the rear differential? Any advice would be great, thanks!
4 year old comment, so you've probably got this figured out by now, but just in case. I've never done an electric conversion, so take this with a grain of salt, but when I looked it up in the past, the method I saw used was to attach the drive motor to the engine side of the transmission and lock the transmission in 2nd gear.
Also some fuel energy is lost to converting gas to motion to electricity to motion instead of moving the car in the first place, its just not efficient.
Left off a big one. Internal combustion dumps a lot of fuel in the engine after a stop light turns green. Electric motor does most of the work at stop lights which doesn't have huge dump a fuel into engine
For fuel to burn you need to adhere to certain ratios. Dumping fuel does not. No engine dumps fuel.
i don't know if this is a stupid question, but what is the difference between Motor and Engine in your diagrams?
Motor would be electric powered whereas an engine would use fuel combustion.
sunyboy is correct. imagine my annoyance with "motor oil" for combustion engines. i work for a company that builds engines and it drives me nuts when people say "motors" when they are talking about cars. then they call themselves car guys. you don't even know what you have under your hood! a huge pet peeve of mine.
Has anybody tried to tune the ICE to run solely on hydrogen from an on demand hydrogen system? I have not had a chance to test a hydrogen generator myself yet but it seems like it would work. This would mean the vehicle is running completely on water. Do we actually have the technology to do this already but no one is doing it yet? From what I understand, the ICE can run completely on hydrogen. However it would take too long for the power to come up if you need to accelerate. But if you are just recharging batteries the system can be tuned to run at a steady RPM when recharging.
What is the best tune/modification you can do to your engine to increase performance that would roughly cost less than $200 ?
Remove unnecessary weight.
Engineering Explained Already done :)
Then you have to spend more now haha. $200 isn't going to get you anything unless you remove things yourself from a scrapped car.
What's the car?
It's a Honda Civic, parallel hybrid system.
Why do hybrid cars today have paddle shifters?
It is too hard bcoz there is no rpm gauge and it is CVT.
You make great videos. Always interesting and helpful. i was wondering if you could go over rust. and the best way to prevent it or seal the metals so they dont rust.
please make a videos about twin turbo engine =)
Look at turbo video , twice ( twin turbo is used on V or flat- engines , one turbo is used on one bank , second on the other ) .
Mladen Milić Nah there's another twin turbo set-up in use with a small and a big turbo, to reduce lag and give power at low RPM.
@CustomSS1"bi" and "twin" mean the exact same thing - "two."
I can provide comfort if needed.
Great and informative
what charges the battery in parallel hybrid
Thanks for explanation!
Thanks man.
Can you do a video of trigger systems, I cant get my head round them! like Inductive/Hall/Optical pulse generators! So frustrating!:L
GOOD JOB THANKS.
Nice ty
The car on the right has the wrong sized tire on, you should not mix tire sizes. Also both cars are missing front wheels, just thought i would point that out
Luckily it's just a drawing, not a real car. :)
Lmaoooo yes its just a drawing
U can't let ethanol sit or it will turn to water and if u don't have a plastic fuel tank that's treated it Will eat through the gas tank and cost more money than what it's worth
Still can't see how hybrids use less fuel. Regenerative braking amounts to so little on a long journey. Prius has over 1700 cc (not a small engine). How much does an engine use on idling? must be tiny amount.
Me too!
can you explain how does the electric motor manage to spin at exactly the same rate as the drive shaft?
Thanks
Because they're connected together. How does the motor on your ceiling fan spin at exactly the same speed as your fan?
wonderful
thanks , your information is really helpful
Series hybrid the only true hybrid. More efficient I think, yes ?
thanks a lot
Excelent
Can you do a video about air conditioning
Thank you for the helpful and informative video.
Great information. Thank you. Then how does PHEV differs from Hybrid vehicles?
tHANKS
Mumbling..hard to understand
If I leave my key turned to start, and step on the gas, I'll have a hybrid car!!!
And a broken starter :)
Wow this is old
KFUPM?
if the batteries go bad which eventually they will then the gas milage drops way down
I don’t see the point of having an engine power a generator to charge a battery to power a motor. That sounds really inefficient.
Its true..
let's not forget to mention the sorry ass tires that hybrids are equipped with that offer minimal traction, and the smaller, lighter brakes that are only installed because it's the law.
Regenerative braking can provide substantial stopping force, so smaller lighter brakes make sense. And if you don't drive aggressively (aka driving a hybrid) low rolling resistance tires will be just fine.
maybe youre looking at the wrong hybrid vehicles...there are many different styles, targeted uses and price range vehicles available...some of which can outperform high line sports cars...expanding your focus might lead to expanding your conclusion a bit...
BUT GREAT PRESENTATION DOE MAH BOI xd
Better
Soooo the f150 is "hybrid" because it has an electric turbo ?
Nope.
What is your dream goal
My goal is car manifecturest
could you make a video on solar power.
the only hybrid i would have would be petrol and ethanol.
That wouldn't be a hybrid, it would be a multi-fuel vehicle, since you can use the same engine for both fuels. The only thing that needs to change is how much fuel is injected, since you need something like 20%-30% more when burning ethanol. And this is done on the fly by the ECU. You can also run a the ignition timing a bit more aggressive on ethanol.
