Abstract
PURPOSE:To make a proper knock judging level settable to an engine by making a limiting range of the knock judging level at a knock judging device for knocking judgment alterable according to a cylinder distributed state when the engine is in a normal driving state. CONSTITUTION:When a knocking state is judged by a knock judging device D according to an output signal of a knock sensor A, a control value for controlling each of knock control factors such as ignition timing and supercharging pressure or the like is operated, by a control valve operational device G, and a value of the knock control factor is varied according to this control value. And, a knock judging level at the knock judging device D is compensated by a judging level compensating device B according to a knocking state. In this case, when compensation of the judging level comes off the specified limiting range, the judging level is set to the said limiting value by a limiting device C. In addition, a mean value of the judging level is calculated at a cylinder state judging device E, and when a deviation between this means value and the judging level is in the specified distributed state, the limiting range of the judging level is altered by a limiting range altering device F on the basis of this mean value.
