  • Method and system for controlling fuel for an engine
    Patent number: 6799565
    Abstract: The present invention relates to a method and system for preventing a lean Air/Fuel ratio that may occur when accelerating an engine. An engine is supplied with a base amount of fuel that is adjusted, or compensated, according to one or more compensation variables that are based on an oxygen sensor signal. If the compensation variables are reduced by more than a predetermined amount and the throttle valve open-angle exceeds a predetermined value, then the method and system of the invention prevent a lean Air/Fuel ratio that may occur by initializing the compensation variables for a predetermined period of time, thereby allowing the engine to perform smoothly.
