Abstract

A fuel system, particularly for a diesel engine, has a closed loop control system including an electronic governor powered by positive and negative supply lines and incorporating a summing amplifier the output from which controls the pump. The non-inverting input of the amplifier is connected to a third supply line, which is maintained at a fixed percentage of the potential between the positive and negative supply lines. Also, the signals applied to the amplifier have magnitudes proportional to the potential between the positive and negative supply lines, so that fluctuations in the supply voltage do not affect the operation of the system.
