PURPOSE:To prevent the air fuel ratio from becoming inadequate by setting an acceleration judgment permission region and stopping augmentation correction even if an engine is shifted into the predetermined acceleration condition or high-load condition when it is outside this region. CONSTITUTION:An operation condition detecting means (a) detecting the engine operation condition using the engine load and rotating speed as parameters and an opening detecting means (b) detecting the opening of a throttle valve are provided. The acceleration condition is judged by an acceleration judging means (c) based on the throttle valve opening, and whether an engine is in an acceleration judgment permission region or not is judged by a region judging means (d) based on the throttle valve opening and rotating speed. In addition, the basic injection quantity is calculated based on the operation condition, the basic injection quantity is corrected by an injection quantity calculating means (e) if the engine is shifted into the predetermined acceleration condition or high-load condition when the engine is in the acceleration judgment permission region, and fuel is fed to the engine from a feeding means (f) according to the corrected injection quantity.
