The Lowest Recorded COMPRESSION RATIO Engines

you what's funny about diesel engines, diesel is verry low octane, so low that for about 20-50 years it was considered as waste from producing gasoline, yet the engines only start at a 1;16 compression ratio and tend to be turbocharged at well

The Tatra V8 was a hemi, and air-cooled!
Felix Wankel, the engine inventor, drove a Tatra!

I don't care if that Tatra V8 had a 1:1 compression ratio - I WANT ONE!
What a stunningly stylish looking vehicle.

The Standard engine in the Ferguson tractor is the same one used in the Triumph TR2, TR3 and TR4 sports cars.

Wow that compression was low, TIME TO SLAP PRO CHARGER on it xD

Thank you for your research ect.

that Lanz Bulldog would probably be heard from miles away with that heavy thumping sound

I guess now I know why old engines sound "old"

Tell us about your cars, is that your Boxster?

Thanks for the videos, cheers!

OMG start fact checking before you post videos your first fact was incorrect and it turned me off to the whole video and I know my comment goes to your paycheck

I have to say i had so many different cars but the one i like to drive the most was a 1968 430ci Buick Wildcat ,it fired about every 4th lamp post was smooth & reliable,and more bottom end than a fat bottom girl , on a good day i could get appx 12 mpg ,but petrol prices killed it for me ! /UK

40s /early 50s they low reving engines in the UK they were reliable & easy to work on then we got the screamers high rpm engines ,and old Standard Vangard or an old Humber /Rover would last for decades ,if you had one fitted with hall effect ignition & fuel injection it would last for a lifetime !

Low compression ratio == beautiful sound

15 liter L4 is a 4 cyclinder I can get behind

I have a 21:1 compression ratio. Mitubishi 4d56 engine(2.5 tb diesel)

I really like these cars. Definitely an interesting perspective on cars because these are not the performance vehicles we normally look at.

I like the aerodynamic car.

The final year for the Ford Flathead V-8 is 1954 for Canada and Australia etc. And 1953 for the US.

Visio in 2050: the last combustion engine cars 🥲

As the first streamlined car, the low efficiency of it's engine is almost funny from today's perspective. I wonder about it's fuel consumption.

I see a Tatra (especially a T77 or T87), I click.

Ford T model 3.5 to 4 to 1 compression ratio

What about a Ford Model A? 4.2:1 Compression Ratio.

I thought Tatra had a 2.5L V8

Hello VisioRacer, thank you for this interesting video. You certainly did a lot of research again. May I " seduce" you to cover TURBO COMPOUNDING. I am sure your subscribers will be interested. It came along on the Douglas DC 7, Boeing B 29, Napier Nomad and even Scania used it in their trucks in the 1990's. Greetings from the Netherlands.

That modle T low revs I bet a lot of them blue up leaving the bar saying watch this nope it quit lol hahaha joking 😆!!

That's crazy 3.8 to 1 Compression ratio and the 1 close to the end of the video u said it ran on gas and k 1 because of the low 4.5 to 1 Ratio allowed it to do that I've never new that was possible!! 2 cool !! I've got a 2 stroke wore out maybe I will try k 1 just to see if it will run !!

Good video.

I'm just commenting because I know that the algorithm likes comments and I want this channel to be as successful as possible.... As a marine mechanic it's awesome to learn about all the different technology used in other fields, such as aircraft or farming equipment... And it's awesome that he is from Eastern Europe because he can tell us about all the crazy soviet Era designs that we never would have seen here in America!
AWESOME CHANNEL!

After WW2 there were heaps of US army blitzwagen trucks around Australia as part of Army surplus sales. They ere also in Army use up until the 1960s. They were made by Studebaker and Ford and, I think, Chevrolet. They had a compression ratio of 5.7 to 1 and the would run on kerosene after you started them on petrol. A lot of them went to farm and logging use. They were common in by boyhood, while they would be curiosities today.

Crikey, l saw the thumbnail and for a split second thought I was looking at an Austin Atlantic! Silly me!

Quite sure that those engines could run with literally everything you can find on the supermarket

Like the Model T ....low compression means they can run on rubbing alcohol.. only then will they prove superior....no one in this present generation realizes how precious that type of vehicle was in a Great depression like in 1929

Man what about the Mopar 318 Piston sets 1/2 inch below deck at TDC. Just having fun love your videos

Did the Expert by min 7 realy turn the left hand bar like a throttle? 🤣 or what did he turn there?

JC is the only one that can keep us all from hell get on the Winning team

What race are you?

Já až teď zjistil, že jsi Slovák 😂🎉

Ratio pressure ok, but the days /months /years next?

Model T hp is 20bhp at 1600rpm and torque is 83ft lbs at 900rpm

Very informative and entertaining!!! Love the video!!!

Can I subscribe twice?

Great compilation. Very enjoyable. But I think the last Ford Model T was produced in 1927.

Imagine if they had evolved throughout the years the classic streamlined design of those Tatra cars like Porsche does with the 911 they would be amazing by now, like futuristic spaceships.

Why do Americans use kph instead of kmh?
I mean... Kmh literally means KiloMeters/Hour.
Kph is not just unnecessary, but it kinda could mean KiloPerHour.

Please just use the best definition kmh, so America is in sync with the rest of the world 😁

one the first car you got something wrong. You wrote 121 mph/ 228 kph. 228 km/h would be 141 mph.
