Answer 1

Diesel engines work on a different principle:

Answer 2

As others have said there's no vacuum in the air intake manifold in a diesel engine. Fuel is injected into the combustion chamber micro moments before the piston creates enough pressure to combust the air fuel mix.
Turbocharged diesels have been more efficient than any gasoline engine. Frenchman, Rudolph Diesel educated in Germany developed the basic engine over a century ago.

Answer 3

First of all, carburetors are horribly inefficient. Second, a diesel engine has no manifold vacuum to suck fuel into the chamber, it would not work. In a diesel engine, the fuel has to be pushed into the chamber.

Answer 4

because diesel is called as heavy oil so cardurator do support diesel fuel. only petrol

Answer 5

Because of the high compression and the fact that the fuel would ignite before it was suposed to.

The fuel has to be injested at the prop[er time to ignite at the proper time.
