PURPOSE:To secure the instantaneousness in fuel injection control by obtaining the advance angle through the fuzzy estimation according to the oxygen concentration in exhaust gas and the knocking information and generating the ignition control signal at the corrected ignition timing corresponding to the advance angle. CONSTITUTION:The advance angle is obtained through the fuzzy estimation by an advance angle estimation device 35 according to the engine revolution speed calculated from the crank angle detected by a crank angle detection sensor 21, feed quantity of the air supplied into a combustion chamber which is detected by an air feed quantity detecting sensor 24, oxygen concentration in exhaust gas which is detected by an exhaust gas oxygen concentration detecting sensor 26, and the knocking information detected by a knocking detection sensor 27. An ignition control signal generator 71 generates the ignition control signal at the corrected ignition timing which is obtained through correction according to the obtained advance angle, and the cylinder information detected by a cylinder detection sensor 28 is judged by a cylinder judging device 51, and the cylinder information is inputted into an ignitor 61 installed on the judged cylinder. Accordingly, the instantaneousness for the ignition control can be secured. |
