Abstract
An engine operating parameter which anticipates knock, such as throttle angle position, is used in combination with a knock sensor to generate a control signal to retard engine spark. For example, the relatively slow response of a low noise sensed knock signal can be compensated by a relatively fast response signal indicating change in the throttle angle position. Thus earlier and improved control of knock can be achieved.
