POWER SUPPLY
The Common Rail fuel system has a special pump that continuously keeps fuel at high pressure, independently from the stroke
and the cylinder which is to receive the injection and accumulates fuel in a common duct for all injectors.
At the electro-injector inlet therefore, there is always fuel at the injection pressure calculated by the ECU.
When an injector solenoid valve is energised by the electronic control unit, the injection of fuel directly taken from the rail takes
place in the corresponding cylinder.
