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 previously obtained according to the driving speed of a car when an aceleration driving is demanded. CONSTITUTION:During the peration of an engine, data to indicate a throttle opening ThS in accordance with a pulse signal from a throttle sensor 48 is provided 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 the car speed VS is referred and when YES, a comparatively great fixed value F is obtained as he 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. |
