| description | A knock detection module for an engine comprises a statistics storage module and a processing module. The statistics storage module stores M times N vibration profiles corresponding to M zones of operation of the engine and N cylinders of the engine, wherein M and N are integers greater than one. The processing module determines in which one of the M zones the engine is operating and determines whether knock has occurred for one of the N cylinders by comparing measured vibration data with a selected one of the vibration profiles corresponding to the one of the M zones and the one of the N cylinders. |
