摘要： PROBLEM TO BE SOLVED: To solve conventional problems that as a result of utilizing different sensors and using different detection mechanisms to detect knocking and misfiring, a computational burden is high in a control device 1 and that although reducing a range in a direction for delaying ignition timing is effective from the perspective of improving internal combustion engine efficiency, trace knock detection is required for that.SOLUTION: Combustion ions generated inside a combustion chamber are detected by using an ion sensor, a signal of the ions is integrated to find an integrated signal, and the integrated signal is compared with a misfiring determination value and a knocking determination value based on a signal averaging integrated signals for a prescribed number of past cycles so as to determine knocking and misfiring. Ignition timing control can be more precise, because a computational burden can be reduced by detecting the misfiring and knocking by the same ion sensor and determination processing is performed with the same determination function logic, and further because setting of a knocking determination threshold enables detection of trace knock.
