Abstract
The outputs generated by the throttle position sensor and the pressure responsive type air flow sensor (or alternatively a flap type air flow meter or the like) are used to generate correction factors which when combined permit the correction of the air flow sensor output for a short period following the initiation of a demand for engine acceleration to obviate the discrepency between the actual and indicated air flows and thus improve the real-time control of the air-fuel ratio (A/F) of the mixture and the level of emission control and performance of the engine.
