Electronic fuel injection controlling method of internal combustion engine

Abstract

Abstract PURPOSE:To improve responsibility in spouting at an initial stage of racing, by making nonsynchronous injection practice when a power switch is turned ON under a racing state, in a method performing an increase of an output of a synchronous injection quantity when the power switch is turned ON. CONSTITUTION:An electronic control fuel injection device corrects a reference injection period of time to be obtained in a controller 48 from outputs of an air flow meter 14 and a distributor 40 by outputs of an O2 sensor 30 and a throttle sensor 22. Then, nonsynchronous injection is made to practice when a throttle valve 20 is opened from a closed state and a throttle switch of the sensor 22 is turned OFF, and synchronous injection is made to practice when the valve 20 is opened more wider than a given opening and a power switch of the sensor 22 is turned ON. In this case, the nonsynchronous injection is made to practice when the power switch is turned ON in a racing state wherein a vehicle is in its suspension time and an engine speed is less than a given value.
