ABSTRACT:
A device for controlling the ignition of an internal combustion engine to eliminate knocking and including a knocking sensor and method for detecting knocking. The knocking sensor is positioned in proximity to one cylinder of the engine and a reference signal is generated when another of the cylinders fires. This reference signal is compared with the output of the knocking sensor to determine a knocking condition.
