INJECTION ADVANCE MANAGEMENT
By means of information relating to the engine speed/TDC, accelerator lever position, atmospheric pres­
sure, temperature of the intake air and temperature of the engine coolant, the electronic control unit cal­
culates the optimum injection advance value and compares it with the actual value transmitted by the
instrument injector and, if necessary, it operates the advance actuator solenoid valve so that the start of
the injection always takes place at the most appropriate moment for all engine operating conditions.
The engagement of the fast idle function is implemented by the control unit when at least one of the fol­
lowing conditions prevail:
1. intake air temperature below 25 °C and engine coolant temperature below 55 °C;
2. air conditioning compressor on;
3. engine speed below 750 rpm.
