Diesel Engine

tucsondude asked:


I know enough about mechanics and how engines work. I know how turbos work in gasoline engines, the fuel/air charge is in the cylinder and the turbo forces in more air and thus more fuel. But if a diesel engine introduces only air and compresses it until the last second when diesel fuel is injected at the top of piston travel, how does a turbo work on a diesel if the fuel isn’t present until detonation?

I saw mythbusters and other shows on BBC America that you can use vegi-oil as feul in a diesel engine. But they all used old vehicles. Is there something in a newer modeled car or truck that prevents the use of vegi-oil as fuel.
