In order to change the injection timing, the amount of fuel pressure added to the timer piston of the injection pump is
controlled, and the position of the piston ... roller relative to the cam plate is changed, which varies the timing of the start of
injection.
The control of injection timing when the timing control valve is ON is explained below. The control ... (TCV).
