Abstract
An engine control apparatus in which a basic fuel injection pulse width is calculated based on various data from various sensors provided for an engine, the basic fuel injection pulse width is corrected by various factors determined based on engine conditions, and a fuel injector provided for the engine is controlled based on the corrected fuel injection pulse width, is characterized in that a period of time from a time the engine is controlled to accelerate whereby an air-fuel ratio changes into a lean state until a time the air-fuel ratio changes into a rich state is detected, and a fuel increment for the acceleration is corrected, based on the detected period of time.
