METHOD OF DETECTING MISFIRE IN AN INTERNAL COMBUSTION ENGINE |
摘要 |
<p>A method of detecting misfire in an internal combustion engine comprises: sensing a temporal signature of a lateral displacement of the engine, performing a spectral analysis of the temporal signature of the lateral displacement to extract a magnitude of a predetermined frequency, and determining that misfiring in at least one of the plurality of cylinders has occurred based on the magnitude of the predetermined frequency. The predetermined frequency is associated with one of a plurality of orders of the engine. The one of the plurality of orders is representative of engine displacement due to in-cylinder pressures. Other methods of detecting misfire and a vehicle are also presented.</p> |
