PURPOSE:To prevent the excessive lean state of mixed gas and improve acceleration performance by increasing the acceleration correction amount by multiplying the correction amount in the case when acceleration is performed from stationary state in the acceleration from deceleration state, by the deceleration correction coefficient. CONSTITUTION:A control unit 16 measures the deceleration lapse time if an idle state is detected when a throttle valve switch 17 is turned ON. When acceleration is detected through the variation of the output of an air flow meter 8, the interruption injection amount searched by a table is multiplied by the deceleration correction lapse time, and interruption injection is performed. Then, the additional increased-amount coefficient and the time are searched from tables and multiplied by the deceleration correction coefficient, and the results are used in the calculation of the normal injection pulse width. Therefore, the excessive lean state of mixed gas can be prevented by increasing the acceleration correction amount, and the acceleration performance from deceleration state can be improved. |
