ABSTRACT:
A system for controlling fuel metering for a multi-cylinder internal combustion engine, having a feedback loop which has an adaptive controller and an adaptation mechanism coupled to the adaptive controller for estimating controller parameters .theta.. The adaptive controller calculates a feedback correction coefficient using internal variables that include at least said controller parameters .theta., to correct a basic quantity of fuel injection obtained by retrieving mapped data by engine speed and engine load, to bring a detected air/fuel ratio to a desired air/fuel ratio. In the system, the internal variables of the adaptive controller are set to predetermined values, when the supply of fuel is resumed after termination of the fuel cutoff, and the adaptive controller calculates the feedback correction coefficient based on the internal variables set to the predetermined value.
