High Pressure Fuel Pump Operation
•
Fuel is drawn and pumped due to the up and down movement of the piston caused by
the rotation of the 3 head cam installed to the rear end of the camshaft (intake side).
•
Fuel pressure is adjusted by the spill valve control solenoid.
•
When the spill valve control solenoid is off, the spill valve is kept open and fuel pushed
out by the piston is returned to upstream, thus fuel cannot be pressurized. When the spill
valve control solenoid is on, the spill valve can operate as a check-valve and fuel pushed
out by the piston is discharged to the fuel delivery pipe, and fuel pressure rises.
