Abstract

PURPOSE: To prevent secular change of injection amount by sensing the wear of roller or cam disc as electric signals, comparing with the reference value through feedback to the control circuit, and by making correction of the control sleeve position signal with its deviation.
CONSTITUTION: The change of position of a plunger 5 caused by wear of a roller 10 cam disc 9, etc. is sensed from the lift of the plunger 5, and the senesd signal is fed back to a control circuit 21 and corrected there for proper injection. The high value of the dielectric voltage wave V2, when the cam disc, roller 10, etc. have worn out is compared with the reference voltage formed by the high value of the dielectric voltage wave when the cam disc 9, roller 10, etc. are not worn, and the amount of wear is sensed from its deviation and corrected with respect to the target sleeve position signal. Thus the injection of the fuel can be maintained constant.
