ABSTRACT:
The present invention provides a system for controlling knock in an engine having one or more cylinders in which combustion occurs. The system includes a sensor that detects the ionization of the combustion process in the cylinders. The ionization is related to the knock intensity occurring in the cylinders, and the sensor further transmits a signal associated with the knock intensity. The system further includes a controller that monitors the stochastic behavior of the ionization signal and adjusts the ignition timing of the engine to operate the engine with an actual knock intensity that is below a knock borderline limit that defines a desired knock intensity.
