ABSTRACT:
According to the present invention, when means is provided for correcting a shift in phase of an engine rotation pulse and a dispersion in responses of an electromagnetic spill valve, and a control signal to a fuel injection pump is corrected in response to an output from the correcting means, if abnormality of output from the correcting means is detected, then the control signal to the fuel injection pump is corrected by use of a fixed valve. As a consequence, even when the output from the correcting means is abnormal, neither excessively large nor excessively small correction is performed and the running at the lowest level can be made, preventing the diesel smoke from being deteriorated and the engine from being damaged.
