1 Diesel Fuel Injection

2 injection in a diesel is a necessityinjection in a diesel is a necessity with gasoline engines, fuel injection is an alternativewith gasoline engines, fuel injection is an alternative diesel injection systems are responsible for fuel delivery and “spark” to initiate and maintain combustiondiesel injection systems are responsible for fuel delivery and “spark” to initiate and maintain combustion

3 Diesel Fuel Injection 6 main functions of a diesel fuel injection system…6 main functions of a diesel fuel injection system…  meter (measuring of fuel) correct quantity of fuel based on the engine’s speed & load  deliver an equal quantity of fuel to each cylinder  control rate of injection (how fast fuel goes in)  time the injection relative to piston position  prevent over-speeding & maintain speed under load  atomize fuel in the cylinder so it vaporizes instantly when injected into the hot air  injection must start & stop abruptly
