Direct Petrol Injection

Course Details

In the world of automotive, fuel injection systems have evolved constantly in search of higher performance while fuel consumption is reduced as emissions.

For these benefits and reduced consumption, developments of systems fuel injection has been completed in the direct fuel injection, making the injection of fuel directly into the cylinder rather than carried out in the intake manifold as embodied injection systems commonly used in front.

Direct injection differs from other systems not only in the place where the injection is done, but it has different operational modes and consists of different elements for carrying out the fuel injection.

The main objectives of this course are:

  • The introduction of direct gasoline injection.
  • Different operating modes in which the system works.
  • The hydraulic circuit of low fuel pressure and its components.
  • The hydraulic circuit of high-pressure fuel and its components.
  • The electrical structure of the system and management by the control unit.
  • The various circuits (admission on …) that make up the injection system.
