What Is A Diesel Injector? Fuel injectors are small electrical components that are used to deliver fuel via a spray directly into the intake manifold in front of the intake valve in a diesel engine. In addition to water in the fuel, injectors are subjected to carbon and dirt particles introduced into the unit via a bad air cleaner element.
What is diesel fuel injector? In a petrol engine, the fuel and air are mixed with each other a long time before they are transported into the cylinder, whereas in a diesel engine, the diesel fuel injector quite literally injects the fuel directly into the cylinder, where it then combines with the air.

Multipoint Injection.
Direct Injection.
Common Rail Injection.
