What is fuel injection and what are different types of fuel injectors!

We know that both petrol and diesel engines are internal combustion engines. Both convert chemical energy into mechanical energy. Chemical explosions take place in the combustion chamber of both type of engines, but the way they take place are different for both of them.

Fuel Injection:

Fuel injection is the introduction of fuel inside combustion chamber of the engine using injectors. All diesel engines use the basic designed fuel injectors whereas petrol engines have anyone of the following two types of injectors:

• Gasoline direct injection
• Indirect injection

Although, petrol engines have replaced fuel injection systems with carburetors. The difference lies in the process how fuel is injected. In the normal systems, the fuel is atomized by the injectors under high pressure by the nozzles whereas in carburetors, fuel injection is dependent upon suction created by accelerated air through venture tube.
