Function requirements for torque coordination, general points

Engine running.

Torque coordination function, general

The torque interface in the CDI control unit (N3/33) coordinates and prioritizes (according to drivability and defined priority) the requirements of all systems that make an engine torque request. It also determines how dynamically each request is to be implemented.

Function sequence for torque coordination

The CDI control unit (N3/33) changes the engine torque through:

Extending or shortening the injection period of the fuel injectors (Y76)

Increasing or lowering the fuel pressure in the rail via the quantity control valve (Y943)
