Abstract of the Disclosure Method for Delivering an Engine Shutdown Signal A method detects the magnitude of knock in an internal combustion engine. A signal responsive to a cavity resonance frequency (f) of a combustion chamber of the engine is processed to produce a knock signal (Fig. 2) having a magnitude responsive to the magnitude of knock. The number of portions of the knock signal (Fig. 2) whose magnitude exceeds a preselected reference is counted; and an engine shutdown signal is delivered in response to the counted number exceeding a preselected number in a predetermined amount of time.
