FUEL FEED CONTROLLER FOR INTERNAL COMBUSTION ENGINE

PURPOSE:To permit the proper air-fuel ratio control independently of the variation of the atomospheric pressure and air temperature by calculating the correction coefficient on the basis of the intake air quantity which is calculated from the throttle valve opening degree and the engine revolution speed and correcting the fundamental feed quantity on the basis of the correction coefficient. CONSTITUTION:An intake air quantity detecting means (a), engine revolution speed detecting means (b), and a throttle valve opening degree detecting means (c) are provided, and the intake air quantity of an engine is calculated by an air quantity calculating means (d) on the basis of the throttle valve opening degree and engine revolution speed. Further, the correction coefficient for correcting the fundamental supply quantity is calculated by a correction coefficient calculating means (e) on the basis of the result of the above-described calculation. Further, the fundamental fuel supply quantity is calculated by a supply quantity calculation means (f) on the basis of the engine intake air quantity and revolution speed, and said fundamental supply quantity is corrected according to the above-described correction coefficient and set as the final supply quantity. A fuel feeding means (g) is controlled on the basis of the final feed quantity, and the fuel quantity supplied into the engine is controlled.
