ABSTRACT:
A fuel feeding system according to this invention has a fuel injector capable of controlling the quantity of fuel to be fed to an internal combustion engine, a first detector for detecting a fluctuated state of combustion in the engine, a fuel feed controller for determining a quantity of fuel, which is to be fed from the fuel injector to maintain an air/fuel ratio of the engine at a value in the neighborhood of a lean combustion limit, on the basis of detection data from the first detector and controlling the fuel injector on the basis of the value of the thus-determined quantity of fuel, a second detector for detecting a state of operation of the engine, a control data updating unit for repeatedly updating the predetermined control data on the basis of the detection data when the engine has been detected to be in a first operation state by the second detector, and a control data holder for holding the control data at a value, to which the control data was updated in the immediately preceding first operation state, when the engine has been detected to be out of the first operation state by the second detector.
