Abstract

PURPOSE: To enable suitable jet time control, by performing open loop control, when abnormality is detected in a jet time detector, so that the working extent of a pressure regulating valve is kept at a prescribed value.
CONSTITUTION: A controller 14 calculates suitable jet time from informations from sensors for detecting the state of an engine, determines a duty ratio of the pressure regulating valve 13 from its erroneous difference from a timer piston position obtained by a jet time detector 15, and controls fuel jet time by feedback control. When abnormality is detected in the jet time detector 15, by lighting a lamp or other means by an abnormality displaying circuit 17 the abnormality is notified to the operator, then based upon the abnormality detection flag from the feedback cntrol by a signal of the detector 15, the duty ratio of the pressure regulating valve 13 is fixed, and it is changed to open loop control. Accordingly, the timer piston position can be controlled proportionary to proportionally to the internal pressure of the pump.
