ABSTRACT:
The injection timing of a fuel injection pump is controlled by displacement of a helical splined sleeve interconnecting a driving shaft and an injection pump drive shaft to vary the angle between the shafts. According to this invention the displacement of the sleeve is effected by an hydraulic actuator controlled by an electronic circuit which is responsive to a number of engine operating parameters and which receives a feedback signal from a detector, preferably magnetic, of the actual relative angular displacement between the shafts to ensure that the actual angle between the shafts is that required by the operating parameters.
