Controlled by the pump control unit, the high pressure solenoid valve determines the
injection quantity and the injection time for each individual injection.
At the bottom dead centre position of the eccentric disc of the axial piston high pressure
pump, the high pressure solenoid valve is closed through the needle valve by a control
impulse from the PCM. The closing timing of the valve determines the start of fuel delivery
from the injection pump.
