摘要
A method includes receiving a noise signal sensed by a knock sensor disposed in or proximate to a combustion chamber of a combustion engine, preconditioning the noise signal to generate a preconditioned noise signal, and process the preconditioned noise signal to determine a location, a time, or a combination thereof, of a peak firing pressure in the combustion chamber of the combustion engine.
