Abstract :
Knock in spark ignition (SI) engines is an undesired spontaneous auto-ignition of the unburned gas mixture, causing high combustion pressure pulses associated with vibration of the engine block. Knocking combustion limits performance, durability and produce more pollutants. In the paper the author proposes a fast knock detection method based on wavelet transform
