INTRODUCTION

An electronic control system supervises and adjusts all the engine parameters, optimising performance and consumption through response in real time to the different operating conditions.

The Diesel engine is fitted with a UNIJET "COMMON RAIL" injection system. This features the use of a high injection pressure controlled electronically. Fuel delivery, called pilot injection, is optimised by the electronic control unit through the injector rather than being controlled by the pump.

Depending on the signals received from a number of sensors, the control unit drives the actuators connected to it, controlling the following systems:

• fuel supply;
• air supply;
• glow plug warming;
• accelerator pedal;
• engine cooling;
• fuel warming.
