Injection device
Diesel engines: injection and combustion chamber

Injection devices, whose construction depends on both the pressure level required and the way it is installed on the engine, can be characterized by :

• how to feed and control the opening of the injector;

• the type of injector nozzle used to distribute the fuel ;

• the technique used to dose the fuel for each injection;

• the design of the injection pump ;

• the location of the injection device and its connections.

It is with these criteria in mind that we will compare the various solutions considered in practice.
