3309859 - 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 features a 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;
• air supply system;
• heater plugs;
• accelerator pedal;
• engine cooling;
• fuel preheating.

For further details, see DESCRIPTION AND OPERATION 1060.Supply lines to the control unit and the various system components (sensors and actuators) are protected by a special maxifuse and another protects the steering wheel fuses, located with the relays in a service tank (behind the engine bulkhead).Glow plug preheating is protected by a dedicated maxifuse located in the engine bay.
