摘要：
An apparatus for detecting abnormal combustion according to the present invention comprises: a unit (5, 16, 17, 19, 20) for detecting the rotation of an internal combustion engine (1); a unit (6) for calculating rotation angular acceleration on the basis of the detected rotation; a unit (7) for comparing the rotation angular acceleration with a predetermined reference value; and a unit (7) for judging whether abnormal combustion occurs. The apparatus for reducing vibration caused by abnormal combustion offsets vibration by passing a pulse-like field current in the electric generator (4) in response to detection of abnormal combustion to generate vibration torque in the electric generator.
