DESCRIPTION

An electronic management system supervises and governs all engine parameters. It optimises performance and fuel consumption by responding in real time to different service conditions.

The system is managed by a single control unit which controls both the ignition and the injection.

The system uses signals received from numerous sensors to control actuators. It is connected to the following systems:

• fuel supply;
• air supply;
• exhaust with catalytic converter;
• fuel vapour recirculation.

For more details, Characteristic of working principle 1056 Fuel injection system .

The system is also controlled by means of two relays located in the engine compartment near the control unit. The supply lines for the control unit and the various system components (sensors and actuators) are protected by a special maxifuse and two other fuses, also located in the engine compartment next to the control unit.
