The opposed piston engine he mentions at 3:30 is a crazy efficient design, mostly because it doesn't lose a lot of heat through the head, because it doesn't have one. They have other huge advantages as well. The crank throw of each piston in a set can be way oversquare, that is, the bore is much larger than the stroke, but since there are two pistons racing away from each other in the cylinder, the effect is of a very long stroke. This means you can get the torque of a long stroking engine, with the higher revving ability of a short stroke. This also means plenty of room to completely burn the fuel. Other major advantages are no head gaskets to blow and no valve train. Although Fairbanks-Morse still makes some monster examples for Navy ships, they mostly went out of fashion in the 1970s because they are all two stroke engines, and it was quite difficult to get their mechanical injection to play nice with emissions regulations. Achates power looks to revitalize the type with computer designed harmonic balancing of exhaust pulses to more completely scavenge exhaust gases. They report 55% efficiencies with their prototype, which means 270 hp from their 2.7 litre three cylinder. ua-cam.com/video/UF5j1DvC954/v-deo.html
About copies of Lanz Bulldog - in Poland we have Ursus C45. Behind that tractor we have fun history. After World War II Polish goverment want to show tractor made in Poland in 1st may parade in Warsaw - 1st may in Poland is Święto Pracy, it's polish version of Workers' Day. They take Land Bulldog, examine tractor, and make some copy of vehicle with Ursus logotype. After this all tractors hits the road to Warsaw to be presented as a new machine for farmers. On parade people seen one tractor, because another machines broke down during the trip to Warsaw. Some people to today said that tractor was Lanz Bulldog with painted Usrus logotype.
Hey Vizio did you know that the bulldog tractor can run at zero rpm? There’s a video out there showing it turn back and forth making it literally run at zero rpm. Enjoy your videos keep up the great work been watching for years
One of my teachers used to work as a marine engineer on a ship. They had a marine diesel throw a rod. To make the engine not try to use its power to work the broken cylinder, they filled the cylinder with concrete and went on with their job.

We used to use a twin turbo Detroit Diesel V12-71 as a starter motor on General Electric Frame 5 and Frame 6 gas turbine generator sets of 24 Megawatt to 32 Megawatt output. The 12-71 would fire up and idle for a few seconds, then accelerate to wide open full power for the next 10+ minutes. It drove a Twin Disk torque converter which turned the accessory gear box. That was coupled to the gas turbine by a jaw clutch. The screaming Detroit would crank the gas turbine to 20% speed where it lit off. The diesel would help accelerate the gas turbine up past 60% speed and then disengage. It would idle for a minute then shut off. That was about 12 minutes of Detroit Diesel engine abuse every time you needed to start up the gas turbine generator. They were very reliable. Ours were rated 600 horsepower.
I don't know why the starter of this engines mesmerize me, makes me relax, even my wife don't understand why I see this videos to get asleep, awesome material as always

Those Lanz Bulldog are very special. Instead of a reverse gear you can let the engine run backwards, and you need to heat them up for them to run. If you let them idle for too long, or drive downhill for too long, the engine will cut out because it gets too cold to ignite the fuel. But due to their low compression ration and simple fuel system you can run them on pretty much anything that burns. They're the OG multifuel engines
I'm surprised you haven't done the English Electric diesel engines. We had them in some of our trains. Max rev was 750 to 900 rpm depending on models. Some are still in full service after 60 years and in my opinion have one of the best sounding large engines.

Wouldn't the Lanz technically win due to being able to run without any revolutions? The back and forth oscillating of the giant flywheel has enough momentum to keep running at *technically* 0 rpm
Nice, interesting collection of engines; I think the Super Landini tractor with an engine similar to the Lanz is a little lower revving at 620 but the most courious thing is it can still run making only half a turn, it's called "mezzo giro", and you can even reverse the engine rotation, but to start it you have to be brave enough to turn with your hands the flywheel
Love it. Technically the Lanz Bulldog can run at 0 RPM, as the cylinder doesn't quiet kick over but bounces back and forth. If you can call that running.
That's not necessarily correct in thr case of medium/ high speed 2 stroke diesels. An air pump - a Rootes blower - is used to supply scavenge air, and it's still classed as N/A
@@jools77 Correct. The blower on a 2-stroke diesel very rarely provides any positive boost pressure. I've seen a few Detroits with overdriven blowers but they're still way below the range of a typical supercharger.
@@jools77 Naturally aspirated means an engine will run on atmospheric pressure alone. The superchargers on Detroit Diesels supply air to run first, and to scavenge next. Without the supercharger it will not run.
The funny thing with Lanze Bulldog, is that you can run it at 0rpm, since the engine can change directions, so with a little adjustment and find the sweet spot, you can have it jumping between rotation direction, without doing a full rotation! Truly weird tractor
Nice video but I missed a whole range of engines like the german deutz and mak engines. Dutch engines like brons, bolnes and industrie. And many other brands worldwide, the 6 cilinder German 545 deutz for example with an rpm between 60 stationary and up to full throttle about 375 rpm. About 500 to 800 hp and weights around 20 tonnes. Had it in a cargo vessel I worked on, absolute beast and will run forever.
The MAN 6S50 still is revving relatively high for Two Stroke Crosshead Marine Diesels. The MAN S Series (S meaning Superlong Stroke) goes up to 900 mm Bore on the S90. I personally worked with a 6S80 ME-C, meaning it has 800 mm Bore and accordingly 3450 mm Stroke (if the S90 has the same Stroke to Bore Ratio, it would have about 3880 mm Stroke but I don't know if that's correct). The 6S80 I worked with goes up to 78 RPM and I'd guess other Verions of it are in a similar Range; e.g. does the Maersk Triple E have two of the same Engines with eight Cylinders instead of six (8S80 ME-C) and IIRC it is built with up to twelve Cylinders for Ships similar of similar Size to the Maersk Triple E Class but with only one Propeller and thus one Engine. Given that the Cylinder Oil (these Engines use different Oils for Cylinders and the Crankcase) can only do it's Job up to a limited Piston Speed, the longer Stroke of the S90 means that it runs even slower. The ME-C means that the Engine is controlled electronically without a Camshaft, contrary to the conventional ME-C Engines. This allows a more flexible Valve Timing which reduces Emissions and becomes particulary useful when burning more than one Fuel, e.g. switching from Bunker Oil to Diesel in Emission Control Areas or the latest Advancements of Dual- and Triple Fuel Engines that can also burn LNG or Methanol (switching from Bunker Oil to Diesel doesn't count as Dual Fuel). MAN also builds an Engine with an even higher Bore of 980 mm; the K98 Series but the K means that it has a shorter Stroke of something in the 2.5-3 m Range IIRC. The largest Internal Combustion Engine ever built is the Wärtsila 14RT-Flex 96C with 14 Cylinders of 960 mm Bore and a Stroke of 2500 mm. It powers the Emma Maersk Class Containerships. I've uploaded a few Videos about that on my Channel; although that was back when I was a Cadet so some of the Informations there aren't 100% precise.

IMO those two stroke EMD locomotive engines are the most musical diesel engines on the planet, in particular the 16-645E3 turbocharged variant found in EMD GP/SD40 and GP/SD40-2 units.
there are a lot of lower revving diesels out there. If you look in to the kromhout engine for example, or the industrie, the deutz brons, stork werkspoor and there are more of them.
The wartsila 96C is the largest engine in the world. Largest is a 14 cyl inline engine. It's the largest, most powerful internal combustion engine ever built. It's a 2 stroke diesel and has a redline of 102RPM. Makes 109,000HP has over 7,000,000lb ft or torque.
Bruhhhh I’ve been watching your videos for quite a long time and this whole time I thought I had subbed 🤦🏻♂️ sorry for the late sub and please keep making videos!
Another superb video!! Bravo!! The very first ship I worked on was the old HMS Endurance. It was fitted with a 5 cylinder hybrid turbo Burmeister & Wain (now MAN B&W) 2-stroke diesel at build in 1967. If the skipper got really excited he could demand a full 102rpm - the redline - from it. Heady stuff indeed, but sadly lacking the offbeat Audi/ VW/ Volvo/ Merc 5 cylinder exhaust burble 😉
Rd6 cat dozer 3 cylinder is one of the best sounding low rev diesels I’ve heard, Detroit has an amazing sound but 2,100 rpm is pretty much where most heavy trucks redline anyway
I can't believe the 3 cyl Cat engines from the mid 30's didn't make this list! RPM at full throttle maxed out at 850, but RPM at greatest torque (maximum power produced) was only 600! Watch this vid to see why : ua-cam.com/video/IF_fR5v2byw/v-deo.html
Hi Sam. Thanks for an interesting video. I especially like 2-stroke diesels. If I may offer some constructive advice, please turn down the volume on the videos and turn your voice up. I found myself turning the video down and your voice up manually all the time. Better sound balance will improve the viewing experience. All the best and looking forward to more! Cheers from Canada.
The English Model-Engineer Magazine (a fortnightly publication) ran a series of articles in the 1980's detailing how to machine & build a scale working model of the Napier Deltic engine. Was quite keen to make one, but unfortunately I recognised that it was beyond the capabilities of my skills, & my very small lathe!
I unfortunately don't yet work on diesel engines, but it's incredibly fun to make the Kohler engines in my vintage Cub Cadets idle as low as possible. Pretty cool sounds they make, but I don't think it beats the sound of an idling Detroit diesel, or the sound of one running high throttle.
2100 rpm on a diesel is actually average on truck diesels as for a 12v71 Detroit I have seen em do up to 3000 rpm. second virtually all Two stroke diesels are forced induction (supercharged) because they can't supply enough vacuum to suck in enough air and has nothing to do with running at high altitudes. Which is one of the reasons you will see them 2 staged with turbos as well. However your doing ok with your research. And pretty good presentation.
Those hot bulb engines didn't just run on diesel, depending on how much you heated the bulb, the engine could even run on kerosene, butter and in some cases petroleum, while only consuming around 300ml of fuel per 10km. Nice one btw
I probably would have included the Wartsila RT-flex96C, 109,000 hp 750 rpm 14 cyl and they make a 16 cyl marine use. I thought you had a past post that included this engine but I could not find it.
The reason for the generally higher torque of a diesel engine compared to an otto engine of similar size is not because of different energy content in the fuel, that difference is not large. The reason is instead the differences in compression ratio, bore:stroke ratio and the speed of combustion. See this video from "Engineering explained" for a more thorough explanation: ua-cam.com/video/D6YmAecTolQ/v-deo.html (He mentions the different energy content of the fuels at the end but as I said, it's no large difference and furthermore, the amount of fuel is not fixed.)

@@jools77 If the scavenge air pump is neither considered a supercharger nor a turbocharger, Connor was right.
@@jools77 Naturally aspirated means an engine will run on atmospheric pressure alone. The superchargers on Detroit Diesels supply air to run first, and to scavenge next. Without the supercharger it will not run.
The largest Sulzer marine diesels have a max rpm of approx. 70. They are among the largest Diesel engines ever made.
Props for the cameramen of the sovjet motor
The funny thing with Lanze Bulldog, is that you can run it at 0rpm, since the engine can change directions, so with a little adjustment and find the sweet spot, you can have it jumping between rotation direction, without doing a full rotation!
Truly weird tractor
Nice video but I missed a whole range of engines like the german deutz and mak engines. Dutch engines like brons, bolnes and industrie. And many other brands worldwide, the 6 cilinder German 545 deutz for example with an rpm between 60 stationary and up to full throttle about 375 rpm. About 500 to 800 hp and weights around 20 tonnes. Had it in a cargo vessel I worked on, absolute beast and will run forever.
Obviously, I cannot fit all the engines into a single video, but they may into next episodes ✌🏻
@@VisioRacer Yes it wil be a very long list when you must mention all of them at once hahaha. But keep going, i like watching your videos💪🏻
The MAN 6S50 still is revving relatively high for Two Stroke Crosshead Marine Diesels. The MAN S Series (S meaning Superlong Stroke) goes up to 900 mm Bore on the S90. I personally worked with a 6S80 ME-C, meaning it has 800 mm Bore and accordingly 3450 mm Stroke (if the S90 has the same Stroke to Bore Ratio, it would have about 3880 mm Stroke but I don't know if that's correct). The 6S80 I worked with goes up to 78 RPM and I'd guess other Verions of it are in a similar Range; e.g. does the Maersk Triple E have two of the same Engines with eight Cylinders instead of six (8S80 ME-C) and IIRC it is built with up to twelve Cylinders for Ships similar of similar Size to the Maersk Triple E Class but with only one Propeller and thus one Engine. Given that the Cylinder Oil (these Engines use different Oils for Cylinders and the Crankcase) can only do it's Job up to a limited Piston Speed, the longer Stroke of the S90 means that it runs even slower. The ME-C means that the Engine is controlled electronically without a Camshaft, contrary to the conventional ME-C Engines. This allows a more flexible Valve Timing which reduces Emissions and becomes particulary useful when burning more than one Fuel, e.g. switching from Bunker Oil to Diesel in Emission Control Areas or the latest Advancements of Dual- and Triple Fuel Engines that can also burn LNG or Methanol (switching from Bunker Oil to Diesel doesn't count as Dual Fuel). MAN also builds an Engine with an even higher Bore of 980 mm; the K98 Series but the K means that it has a shorter Stroke of something in the 2.5-3 m Range IIRC. The largest Internal Combustion Engine ever built is the Wärtsila 14RT-Flex 96C with 14 Cylinders of 960 mm Bore and a Stroke of 2500 mm. It powers the Emma Maersk Class Containerships.
I've uploaded a few Videos about that on my Channel; although that was back when I was a Cadet so some of the Informations there aren't 100% precise.

IMO those two stroke EMD locomotive engines are the most musical diesel engines on the planet, in particular the 16-645E3 turbocharged variant found in EMD GP/SD40 and GP/SD40-2 units.
Thanks for the great video! I think the bore and stroke figures might be wrong for the EMD engine, though
I love how every time I wonder about something, my main man Visio uploads a video on it😂😁 love the vids man keep it up👍
Borat explains diesel power!😂
Veri nice!
Lanz Bulldog copies are:
Pampa T01/TO1 in Argentina,
Ursus-C45/C451 in Poland
Kelly and Lewis Bulldog or KL Bulldog in Australia
there are a lot of lower revving diesels out there. If you look in to the kromhout engine for example, or the industrie, the deutz brons, stork werkspoor and there are more of them.
Sugestion: Higgest Power N/A street diesels
Check out the large cat d342 and similar larger engines they only rev to around 1300 I dont know what the idle is it but it sounds low around 400ish
The Deltic is a seriously smooth running beast.
Anyway.... TANKS! TRAINS! Massive engines with STAIRCASES on cylinder head \o/ We want MORE :P
The wartsila 96C is the largest engine in the world. Largest is a 14 cyl inline engine.
It's the largest, most powerful internal combustion engine ever built. It's a 2 stroke diesel and has a redline of 102RPM. Makes 109,000HP has over 7,000,000lb ft or torque.
Tento chlapík je veľký frajer, má úžasný kontent
Ďakujem, vážim si to!
Been watching for a long time, first time I’ve ever seen you! Lol. I love your content!!
Very nice video! But there is 1 engine i think needs to be in this list. And that is the Industrie 3VD6 a big Dutch diesel engine.
That last engine sounded like music to my ears
Loved the vid. But you forgot to mention that Lanz Bulldog could run at 0 rpm. Go look it up!
Bruhhhh I’ve been watching your videos for quite a long time and this whole time I thought I had subbed 🤦🏻♂️ sorry for the late sub and please keep making videos!
Nice research into specific type of engine
Great research, very Nice and instructive vidéo,continue 👍🤟🤙💪🏍🏍
The EMD 16-645 was also used in the terex titan mining truck.
Nothing sounds as good as big EMD's.
Another superb video!! Bravo!!
The very first ship I worked on was the old HMS Endurance. It was fitted with a 5 cylinder hybrid turbo Burmeister & Wain (now MAN B&W) 2-stroke diesel at build in 1967. If the skipper got really excited he could demand a full 102rpm - the redline - from it.
Heady stuff indeed, but sadly lacking the offbeat Audi/ VW/ Volvo/ Merc 5 cylinder exhaust burble 😉
Love your videos Mr.Racer, lol
Rd6 cat dozer 3 cylinder is one of the best sounding low rev diesels I’ve heard, Detroit has an amazing sound but 2,100 rpm is pretty much where most heavy trucks redline anyway
I can't believe the 3 cyl Cat engines from the mid 30's didn't make this list! RPM at full throttle maxed out at 850, but RPM at greatest torque (maximum power produced) was only 600!
Watch this vid to see why : ua-cam.com/video/IF_fR5v2byw/v-deo.html
Hi Sam. Thanks for an interesting video. I especially like 2-stroke diesels.
If I may offer some constructive advice, please turn down the volume on the videos and turn your voice up. I found myself turning the video down and your voice up manually all the time. Better sound balance will improve the viewing experience.
All the best and looking forward to more!
Cheers from Canada.
Thank you. Will do!
@@VisioRacer Thanks, mate! Take care.
The English Model-Engineer Magazine (a fortnightly publication) ran a series of articles in the 1980's detailing how to machine & build a scale working model of the Napier Deltic engine. Was quite keen to make one, but unfortunately I recognised that it was beyond the capabilities of my skills, & my very small lathe!
I would like to see a video on the quietest engines ever made.
Hmm
Made by a watch company in switzerland.the company is called Tik tok the engine just ticks when you wind it up.
Quietest combustion engine is probably an old, low-rpm Stirling engine...
Like a pulse jet? 🤣
I unfortunately don't yet work on diesel engines, but it's incredibly fun to make the Kohler engines in my vintage Cub Cadets idle as low as possible. Pretty cool sounds they make, but I don't think it beats the sound of an idling Detroit diesel, or the sound of one running high throttle.
TORQUE!! Let’s add that to the videos.
Thank you for pronouncing the name of the engine and it’s home correctly, it’s “Deeeetroit”. Thanks again.
Can you do a video on the few diesel aircraft engines? Keep up the killer vids man 😁
Good idea
2100 rpm on a diesel is actually average on truck diesels as for a 12v71 Detroit I have seen em do up to 3000 rpm. second virtually all Two stroke diesels are forced induction (supercharged) because they can't supply enough vacuum to suck in enough air and has nothing to do with running at high altitudes. Which is one of the reasons you will see them 2 staged with turbos as well. However your doing ok with your research. And pretty good presentation.
Those hot bulb engines didn't just run on diesel, depending on how much you heated the bulb, the engine could even run on kerosene, butter and in some cases petroleum, while only consuming around 300ml of fuel per 10km. Nice one btw
Best EFI engines nex video?
They're all EFI now. Who determines what "best" is?
I probably would have included the Wartsila RT-flex96C, 109,000 hp 750 rpm 14 cyl and they make a 16 cyl marine use. I thought you had a past post that included this engine but I could not find it.
you know its low when it sound like gunshots when u drive
Small diesel engines are not impressive, but massive engines are great. Diesel power - Prodigy.
The Lanz Bulldog, can run on 0 RPM, because it is a 2stroke and have a massive piston
Thank you for the well presented informative vidio.
The reason for the generally higher torque of a diesel engine compared to an otto engine of similar size is not because of different energy content in the fuel, that difference is not large. The reason is instead the differences in compression ratio, bore:stroke ratio and the speed of combustion. See this video from "Engineering explained" for a more thorough explanation: ua-cam.com/video/D6YmAecTolQ/v-deo.html
(He mentions the different energy content of the fuels at the end but as I said, it's no large difference and furthermore, the amount of fuel is not fixed.)
yeah we support you my dear
Speaking of Kelvin Engines I had to get water pump parts for a Kelvin T6 engine the other week.
You forgot the Caterpillar D9 from 1966 it was about 600 rpm at idle and 900 rpm at full throttle
