Abstract
PURPOSE:To improve accuracy in learning control and prevent air-fuel ratio from variation by storing an air-fuel ratio feed-back correction amount, calculating and storing an ineffective time correction amount of a fuel injection valve from value stored in low load value and a flow characteristic value correction amount of fuel injection valve from value stored in high load. CONSTITUTION:To a control unit 10 are supplied the detecting values of an air flow meter 1, crank angle sensor 2, air-fuel ratio sensor 3, water temperature sensor 4, throttle valve opening sensor 5, etc. to correct a basic injection amount with various correction amounts according to intake air amount and rotational frequency. That is, a learning value is renewed by an air-fuel ratio feed-back correction amount in every area defined by (intake air amount/rotational frequency, rotational frequency) to calculate and store an ineffective time correction amount of a fuel injection valve from a learning value in the low load region and a flow characteristic value correction amount of the fuel injection valve from the leaning value in high load region for correcting the basic injection amount.
