Knock Sensor in Chevrolet Corvette is applied to detect the knock condition of the engine and its signal to the powertrain control module to regulate the timing. Characteristically piezoelectric, the sensor translates the generated shaking movements into electrical signals in order to watch pressure spikes indicative of knock. This enable accurate timing correction for performance and protection of the components from the effects of lower octane fuels. Some sophisticated systems can use the modulation of the timings of cylinders and regulate the boost pressure, therefore the optimal performance along with durability in various conditions. Corvette's Knock Sensor technology is an example of the transition of engine management systems for better performance and durability.
