ABSTRACT OF THE DISCLOSURE An abnormal combustion-detecting device and a combustion control device for internal combustion engines. Ignition timing for the cylinders is set in accordance with engine operating conditions. The set ignition timing for at least one of the cylinders is retarded when the engine is in a predetermined operating condition. Abnormal combustion caused by postignition within the at least one cylinder is detected when the set ignition timing is retarded. When abnormal combustion is detected within the at least one cylinder, temperature within the cylinders is lowered, thereby positively preventing possible occurrence of preignition.
