Abstract
A fuel system for an engine has a pump which supplies fuel to the engine and an actuator for controlling the pump output. The actuator is controlled by a control circuit to which are fed electrical signals representing demanded engine speed, actual engine speed and pump output. The control circuit sets the slope of the pump output versus speed curves of the engine, and speed-sensitive means operates below a predetermined engine speed for modifying this slope to make it shallower and so produce a smaller change in pump output for a given change in speed.
