ABSTRACT:
A method and apparatus for comparing torsional stress/strain states of a power transmitting member of an internal combustion engine to detect an abnormal combustion condition, including misfire or roughness. A first signal is obtained relating to the torsional stress in the member produced by a first combustion event or series of events. A second signal is obtained which relates to the torsional stress in the member produced by a second combustion event or series of events. The first and second signals are compared to detect the abnormal combustion event in the operation of the engine. A magnetostrictive sensor may preferably be used to obtain the signals relating to the torsional stress in the power transmitting member, such as the engine crankshaft.
