An electronic control system supervises and governs all engine parameters to optimise performance and fuel consumption by means of a real-time response to different service conditions.The Diesel engine is equipped with a COMMON RAIL UNIJET injection system. This features high, electronically-controlled injection pressure.Fuel is delivered in the form of a pilot injection. This is optimised by the electronic control unit by means of the injector instead of being managed by the pump.Depending on the signals received from numerous sensors, the control unit controls the injectors connected to it managing the following systems:
fuel supply;
air supply;
accelerator pedal;
engine cooling.
The electronic management system described above ensures that this engine meets the very latest EOBD (European On Board Diagnogis) system emission control and monitoring requirements. This system allows continous diagnosis of emission-related car components and notifies the driver if any of the components should deteriorate by turning on a warning light and showing a message on the instrument panel matrix display.The system is also controlled by dedicated relays in the engine bay control unit. Lines supplying the control unit and various system components (sensors and actuators) are protected by dedicated fuses that are also located inside the engine bay.
