Abstract
Knock in spark ignition (SI) engines is an undesirable mode of combustion, causing high combustion pressure pulses associated with vibration of the engine block. This phenomenon limits performance, durability and fuel economy of SIengines. In this paper the author propose; a new knock detection method called WBKD (Wavelet Based Knock Detection), which is based on wavelet transform. Real data experiments confirmed the utility of the proposed approach for knock intensity estimating.
