摘要
A knock detection system for a spark-ignition engine includes a knock sensor that is responsive to vibration of the engine and that generates a knock signal. A first module calculates a knock energy based on the knock signal and a second module calculates a knock intensity based on the knock energy. A third module regulates a spark timing of the engine based on the knock intensity.
