ABSTRACT:
A system for detecting a combustion knock occurred in a combustion chamber of an internal combustion engine. The system includes a sensor for detecting vibration generated in the engine. Sensor output within a range of crankshaft angles during which no combustion occurs is averaged and amplified to determine a reference noise level. Sensor output within another range of crankshaft angles during which combustion occurs is compared with the reference noise level and if the sensor output exceeds the reference noise level, a combustion knock is determined to be present. In the system, a traction control system (TCS) is incorporated in which the engine output torque is reduced when the driven wheel of the vehicle on which the engine is mounted is great. The reference noise level is enlarged when the TCS operates such that the mechanical vibration increased by the sudden change in the torque due to the TCS operation is prevented from being erroneously detected as the combustion knock.
