PURPOSE:To secure the instantaneousness in fuel injection control by installing an air feed quantity estimation device, load estimation device, advance angle estimation device and an ignition control signal generator. CONSTITUTION:The effective feed quantity of the air supplied into a combustion chamber is obtained through the fuzzy estimation according to the feed quantity of the air supplied into the combustion chamber of the engine and the oxygen concentration in exhaust gas. The load applied to the engine is obtained through the fuzzy estimation according to the engine revolution speed calculated from the crank angle and the oxygen concentration in exhaust gas. The advance angle is obtained through the fuzzy estimation by an advance angle estimation device 35 according to the effective supply quantity of the air supplied into the combustion chamber, knocking information and the load. An ignition control signal generator 71 generates the ignition control signal at the corrected ignition timing which is obtained through the correction according to the obtained advance angle, and inputs the detected cylinder information to an ignitor 61 installed on the judged cylinder. Accordingly, the instananeousness for the ignition control can be secured. |
