Electronic injection 5AM 2
Electronic injection 5AM 2
Actuator control is determined by the information received from the sensors:
- amount of fuel injected to each cylinder in sequential mode and not parallel, by
controlling the opening time of the injectors and thus also injection timing is
referred to the intake stroke of each cylinder
- ignition timing advance (ignition coil)
Principal novelty on the system of injection with computer Marelli 5AM 2l lies in
idle speed
the control of that is affected by a stepper motor that allows air to
enter in the combustion chamber by-passing the throttle valve.
Its position is modified by the computer to maintain idle speed stabilized, in
function of environmental conditions (engine temperature, air temperature,...)
