回避装置。 A knocking avoidance device for a supercharged internal combustion engine includes a knocking avoidance control means that detects knocking occurring in the supercharged internal combustion engine and corrects ignition timing to avoid knocking,
Detected by the intake air temperature detection means for detecting the temperature of the supercharged intake air, the retard correction value storage means for storing the retard correction value of the ignition timing according to the intake air temperature, and the intake air temperature detection means. The invention further includes a retard correction value search means for searching a retard correction value for ignition timing from the intake air temperature, and an ignition timing correction means for outputting the retrieved retard correction value to the ignition timing control means. Features a knocking avoidance device for internal combustion engines with a supercharger.
