Abstract

PURPOSE:To generate maximum torque with few fuel in high load stabilization by enabling an optimum control point providing the maximum torque and smallest fuel consumption to be searched in knock-MBT control leaning also air fuel ratio. CONSTITUTION:A knock-MBT controlling means 4 is provided which receives the respective output signals of a knocking sensor 1 and a detecting means 3 for detecting a maximum in-cylinder pressure crank angle (MBT correlation amount). Here, the deviation of knocking signal from the desired value and the deviation of detected value of MBT correlation amount from the desired value are obtained to carry out knock-MBT control on the basis a feed-back amount of ignition timing and a learning value about ignition timing obtained from these deviations. Then, the detected values of MBT correlation amounts before and after the corresponding control are stored 11 and the one detected value of both MBT-correlation amounts for minimizing the deviation from the desired value is selected 12 so that the learning value is renewed 13 on the basis of a feedback amount corresponding to the selected MBT correlation amount.
