摘要： PROBLEM TO BE SOLVED: To solve a problems wherein, when an increasing rate is calculated from the increasing amount of ion current and the width of a predetermined crank angle and it is determined based on the increasing rate whether a combustion state is normal combustion, knocking or preignition, the preignition is not detected until the increasing rate advances to the predetermined crank angle, and as a result, start of control for suppressing the preignition is delayed, and a drop in combustion efficiency during a period when the sign of the preignition occurs is left as it is.SOLUTION: The maximum value of the increasing rate is calculated from an ion current waveform detected by an ion current detection circuit. A crank angle sensor detects the angle of a crank at a position where the increasing rate of the ion current waveform is at an maximum. When the increasing rate of the ion current waveform detected by the ion current detection circuit is an increasing rate threshold or higher and the crank angle detected by the crank angle sensor advances in comparison with a crank angle threshold, it is determined that the sign of the preignition or the preignition occurs.

摘要： PROBLEM TO BE SOLVED: To solve a problem that a user sometimes suffers from a sense of discomfort as knocking occurs a plurality of times in such a case where: if all cylinders are controlled to retard together when knocking occurs, cylinders without the knocking are made to similarly retard in ignition timing, resulting in a drop in efficiency of cylinders with good combustion efficiency; and, on the contrary if the knocking is detected for each cylinder and only the cylinder with the knocking is retarded in ignition timing, the knocking may occur on two or more cylinders depending on load or driving conditions of the engine, and operation since the occurrence of the knocking until retard control is repeated for each cylinder.SOLUTION: A cylinder on which the knocking is detected by a knocking detecting means is assumed to be a first cylinder. An ECU calculates a retard amount of an ignition signal for inhibiting the occurrence of the knocking in the first cylinder for the subsequent combustion. While an internal combustion engine is accelerating, the ignition signal from the ECU for cylinders other than the first cylinder has a retard amount reflected in a range of 30-50% of the retard amount for the first cylinder.
