Fuel pressure builds at the base of the plunger in the barrel. When the intensifier piston pushes the plunger down, the plunger increases fuel pressure…

When the spool valve is open, high-pressure oil enters the injector pushing down the intensifier piston and plunger. Since the intensifier piston is 7.1 times…

An OPEN coil and a CLOSE coil on the injector move the spool valve from side to side using magnetic force. The spool has two…

Two 48 volt 20 amp coils control a spool valve that directs oil flow in and out of the injector. The injector coils are turned…

The IPR solenoid receives a pulse-width modulated signal from the ECM that indicates the on and off time the control valve is energized. The pulse…

The ICP is a closed loop system that uses the ICP sensor to provide feedback to the ECM. The ECM uses the ICP sensor to…

The oil reservoir in the front cover provides a constant supply of oil to a high-pressure oil pump mounted to the backside of the front…
