Abstract
In a fuel injection apparatus for an internal combustion engine which has a fuel injection pump having a plunger and one control sleeve fitted on the plunger and capable of regulating both the fuel injection quantity and the timing of the beginning of fuel injection by the adjustment of the relative positional relationship therebetween, and a control unit for controlling the positional relationship in order to obtain the optimum fuel injection rate and fuel injection quantity, the apparatus comprises a detector for detecting any trouble occurring in the control system for regulating the position of the control sleeve and a limiting circuit for limiting the control operation by the control unit so that an excessive rise in the inner pressure of the cylinders in the internal combustion engine is prevented when the occurrence of the trouble is detected by the detector.
