ABSTRACT:
In a diesel engine having a rotational angle sensor for detecting the engine speed, when the rotational angle sensor is in an abnormal state, a fuel-cutting operation is performed. A first fuel-cutting operation is immediately performed so as to indicate to the driver that an abnormal state exists. However, subsequent fuel-cutting operations after restarting of the engine are delayed as compared with the first fuel-cutting operation.
