nice, and what about cvt ones?

Wrong again. Both have fuel injectors. Diesel has glow plugs or a heating coil to prevent heat the air, but the combustion happens by pressure only. The gas engine has a spark plug achive combustion.

Why is disel emgine larger in size

Good. But gasoline motor uses a inyector too. There is a mistake in the video at this point.

I didnt know all diesel were direct injection like this,. cool

Diesel more efficient?

Very good and simple explanation gracias

it isn't C.R Vtotal/Vc ?
in the video he said the opposite ....why?

So, diesel for sports cars is essentially pointless? Heavier engine means heavier frame to support it. It's also slightly more expensive, fuel efficiency helps but not by a large enough amount to overcome the cost of diesel.

So why the hell do diesel sports cars exist??

What if diesel fuel is preheated and vaporized ?

Gas?? it's called petrol. Sedan?? It's called a saloon. Station wagon?? it's called an estate. A tire?? no it's actually spelt tyre. a stick shift? no it's actually called a manual gearbox. dumbass americans

Thanks for the explanation.

excellent video

MISTAKE
compression ratio is total volume divided by clearance.

Modern Gasoline engine also contains injector :-)

+Learn Engineering I have a question. with which program you create this animation

I dont even know where to start. (－‸ლ)

Kellogg's frosted flakes. Please stop trying and advertising everywhere. Nobody eats that crap anymore

what if we add some gas hydrogen to both of this engine ?

So if petrol engines uses spark plugs,why does it need petrol?
