DESCRIPTION

3.0 V6, 3.2 V6

GENERAL SPECIFICATIONS

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;
• crankcase vapour/gas recirculation system;
• fuel evaporation control system;

Cooling system

Forced circulation with centrifugal vane pump
