PURPOSE:To prevent mixed gas in the early stage of the accerelation of an engine from being excessively concentrated by providing a correction amount operating circuit additionally performing correction for reducing an injection amount by a prescribed amount for a prescribed period in the early accerelation stage of the engine. CONSTITUTION:A basic injection amount signal Tp is computed from an air intake amount Qa and the number of revolution of an engine Ne. In order to correct this basic injection amount signal Tp according to the operating parameter of the engine, a hybrid correction amount operating circuit 22 is provided. The basis injection amount signal Tp is corrected in a multiplying circuit 23, according to the engine operating parameter, driving an electromagnetic fuel injection valve 5. In the circuit 22, correction for reducing the injection amount by a prescribed amount for a prescribed period in the engine accerelation early stage is additionally performed. In this way, mixed gas can be prevented from being excessively concentrated in the early acceleration stage. |
