2889410 - 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, electronically-controlled injection pressure. 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 system;
• air supply system;
• heater plugs;
• accelerator pedal;
• engine cooling;
• fuel preheating.

For more details,  see DESCRIPTION AND OPERATION: 1060  DIESEL FUEL INJECTIONThe system is also controlled by means of special relays located in the engine compartment in the relay and fuse box.The supply lines for the control unit and the various system components (sensors and actuators) are protected by a special maxifuse and other fuses, also located in the above mentioned box.The pre-heating system is protected by a special maxifuse located next to the box in question.
