PURPOSE:To improve the response and the driverability for acceleration by controlling the supply of fuel in accordance with the supply amount of fuel for acceleration obtained according to the driving speed of a car when an acceleration driving is demanded. CONSTITUTION:During the operation of an engine, data to indicate a throttle opening speed ThS is provided on a pulse signal from a throttle sensor 48 in an MPU in a control circuit 30, and when these data ThS are greater than a fixed value E, it is judged that an acceleration driving is demanded. When this acceleration driving is demanded, whether a car speed VS obtained from the output of a car speed sensor 54 is greater than a fixed value or not is decided. When the decision is NO, an asynchronous injection pulse width TAU' to correspond to a revolution speed NE is referred, and when YES, a comparatively great fixed value F is obtained as the asynchronous injection pulse width. Then, an injection pulse signal in accordance with the said asynchronous injection pulse width is supplied to a fuel injection valve 26 for injecting a proper amount of fuel. |
