PURPOSE:To maintain the normal output of an engine, by compensating malfunctioning of a throttle-valve opening sensor or other by cancelling interruption of fuel supply in spite of an output signal indicating deceleration of an engine when the engine load and the incremental rate of the engine speed are higher than respective predetermined values. CONSTITUTION:The title apparatus of this invention comprises a means 3 for stopping fuel supply when the engine speed detected by a rotation sensor 1 is higher than a predetermined value and it is detected by a throttle-valve opening sensor 2 that a throttle valve is in its completely closed position, a means 4 for detecting the incremental rate of the engine speed, a means 5 for detecting the engine load, and a means 6 for cancelling interruption of fuel supply in case that both of the engine load and the incremental rate of the engine speed are higher than respective predetermined values even if conditions for stopping fuel supply are satisfied. Further, the apparatus comprises a means 7 for calculating the pulse width of fuel injection from the output signals of the rotation sensor 1 and said means 5 and a means 8 for driving a fuel injection valve 9 on the basis of the result of the above calculation. With such an arrangement, fuel supply is continued except for the time when an engine is operated under particular dece- lerating conditions.
