PURPOSE:To improve the performance of an engine at the time of acceleration, by supplying an optimum amount of fuel by effecting additional supply of fuel on the basis of the opening degree and the opening speed of a valve which is provided in a passage of intake air for controlling the quantity of intake air. CONSTITUTION:The supply rate of fuel is determined on the basis of the speed of rotation of an internal-combustion engine M1 and the quantity of intake air controlled by a valve M3. An asynchronous fuel supply means M6 effects additional supply of fuel to the engine M1 asynchronously with rotation of the engine M1. Further, an additional fuel supply control means M7 supplies fuel by controlling the asynchronous fuel supply means M6 on the basis of the valve opening degree detected by a valve opening degree detecting means M4 and the rate of change of the valve opening detected by a valve opening speed detecting means M5. Since, with such an arrangement, an optimum amount of fuel is supplied at the time of accelerating an engine, it is enabled to improve the driving performance of the engine. |
