Electro—injector
The high—pressure pump keeps the delivery fuel pressure constantly high, irrespective of the phase and the cylinder that must
receive the in jec t ion and it accu mulates the fuel in the common rail and piping to all the electro—injectors.
At the electro—injector inlet there is therefore alway s fu el available at the injection pressure c alculated by the engine’s electronic
control unit (ADEM III).
When the solenoid valve of an electro—injector is energized by the electronic control unit, fuel taken directly from the rail is
injected into the relevant c ylinder.
