Provide high pressure, quantitative, timed diesel fuel to the injector. Principle: adjust the oil pump plunger through the throttle rack (the plunger has a chute for oil return, that is, the oil supply ends)
Angle (the oil output valve is controlled by the CAM valve switch quantitative, timing) quantitative oil supply, through the CAM Angle timing oil supply.
Quantification is throttle control, timing is fuel supply (injection) advance Angle.
