Engine Iveco C10/C13/C78/Cursor 13/Cursor 78. Manual — part 7
Injection phase
The injection phase begins when, at a certain point in the
down phase of the pumping element, the solenoid valve gets
energized and the fuel valve (1) shuts.
The moment delivery begins, appropriately calculated by the
electronic control unit, depends on the working conditions
of the engine.
The cam continues with the rocker arm to push the pumping
element (2) and the injection phase continues as long as the
fuel valve (1) stays shut.

Pressure Reduction phase
Injection ceases when the fuel valve (1) opens, at a certain
point in the down stroke of the pumping element, after the
solenoid valve gets de-energized.
The fuel flows back through the open valve (1), the injector
holes and the passage (4) into the cylinder head.
The time for which the solenoid valve stays energized,
appropriately calculated by the electronic control unit, is the
duration of injection (delivery) and it depends on the working
conditions of the engine.
