Gasoline and natural gas engines run with a compression ratio of between 
8.5:1 and 11:1 nowadays. Diesel engines require a minimum compression ratio 
of 22:1, since diesel fuel requires a lot of heat and extreme pressure to 
ignite. Natural gas engines use carburetors, while the newer gasoline 
engines are using fuel injection.

The diesel genset engines use direct injection, there are no carburetors 
for diesel engines. Diesel fuel cannot be atomized by a carburetor the same 
way gasoline can, since it is a fuel oil.
