3234564 - E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT - Description

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 Diesel engine is fitted with a COMMON RAIL UNIJET injection system. This uses high injection pressure controlled electronically. Fuel delivery, termed a pilot injection, is optimised by the electronic control unit via the injector and not managed by the pump.

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

• fuel supply;
• air supply:
• glow plug preheating;
• accelerator pedal;
• engine cooling system;
• fuel preheating.

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