ABSTRACT:
An apparatus for use in an internal combustion engine including a single fuel injector provided for supplying fuel to an internal combustion engine upstream of an intake manifold connected to a plurality of cylinders. The apparatus includes a control circuit for provide a commend to cause the fuel injector to inject supplemental fuel to the engine in response to a demand for engine acceleration in order to provide a good acceleration performance. The amount of the supplemental fuel supplied to the engine is decreased in a manner to avoid creation of an overrich mixture in the cylinders when a demand for engine acceleration occurs again in a short time after the throttle valve closes to an angle less than a predetermined value.
