  • Method and apparatus for detecting discrete levels of detonation in an internal combustion engine
    Patent number: 4829956
    Abstract: A method detects the magnitude of knock in an internal combustion engine. Each knock is quantified into a discrete level which gives an indication of the operating condition of the engine. The discrete level signals provide information helpful during engine calibration and engine monitoring. After a predetermined number of level signals indicative of preselected magnitudes of knock are received, an engine shutdown signal is delivered which ceases engine operation.
