Many late model engines have a "knock sensor" on the engine that responds to the frequency vibrations characteristically produced by detonation (typically 6-8kHz). The knock sensor produces a voltage signal that signals the computer to momentarily retard ignition timing until the detonation stops. What causes an engine to knock under acceleration? The static compression ratio of engine will increased when cylinders has been bored to oversize and an engine have been rebuilt. Or to restore flatness the resurfaced have been done in the...
