The unit is composed of the engine and all the systems involved in its operation:
fuel supply system
air supply system
exhaust system
emission control system
engine cooling system.
The optimum operation of these systems is achieved through an electronic control system managed by a control unit.Understanding the operating logics of the control unit makes it possible to have an overall picture of the entire GROUP 10 system
Fuel supply system
It is the returnless type with an electric fuel pump submerged in the tank and enclosed in a container together with the pressure regulator, the level gauge and the filter (for further details see 1040).
Air supply system
Intake air supply system with motorized throttle operated directly by the injection/ignition control unit [DF 1048].
Exhaust system
The exhaust system is equippede with a three-way catalytic converter and Lambda sensor [DF 1076]
Emission control system
The following emission control systems are designed for this model:
exhaust emission control system with three-way catalytic converter and Lambda sensor;
