    摘要： Method for detecting misfiring in an internal combustion engine with the steps of

    (A) detecting the combustion light intensity or the combustion temperature in respective combustion chambers (23a-d) of the engine,
    (B) converting the combustion light intensity or the combustion temperature into electrical signals (50a),
    (C) determining a misfire of the engine if an average signal level (V p ) of the electrical signals for a predetermined number of power cycles of the engine is below a predetermined slice level (S), and
    (D) correcting the A/F-ratio and the ignition timing of the engine in accordance with the detected misfire.

    摘要： A method of air-fuel ratio control for automotive internal combustion engine is disclosed, in which the amount of fuel to be supplied to the internal combustion engine is determined in accordance with the amount of air passing through a main air intake path (16), and the amount of air in a bypass (32) is controlled in a manner to attain a predetermined air-fuel ratio for a lean mixture gas which in turn is determined by a predetermined operating mode (81 to 82) of the automobile. The amount of supplied fuel which changes with the amount of air in the bypass is thus corrected to perform the lean mixture gas operation in the predetermined operating mode.
