1/00 Controlling fuel-injection pumps, e.g. of high-pressure injection type (F02D 3/00 takes precedence)
1/02 Controlling fuel-injection pumps, e.g. of high-pressure injection type (F02D 3/00 takes precedence) not restricted to adjustment of injection timing, e.g. varying amount of fuel delivered
1/04 Controlling fuel-injection pumps, e.g. of high-pressure injection type (F02D 3/00 takes precedence) not restricted to adjustment of injection timing, e.g. varying amount of fuel delivered by mechanical means dependent on engine speed, e.g. using centrifugal governors (F02D 1/08 takes precedence)
1/06 Controlling fuel-injection pumps, e.g. of high-pressure injection type (F02D 3/00 takes precedence) not restricted to adjustment of injection timing, e.g. varying amount of fuel delivered by means dependent on pressure of engine working fluid (F02D 1/08 takes precedence)
1/08 Controlling fuel-injection pumps, e.g. of high-pressure injection type (F02D 3/00 takes precedence) not restricted to adjustment of injection timing, e.g. varying amount of fuel delivered Transmission of control impulse to pump control, e.g. with power drive or power assistance
