Knock Sensor used in Cadillac DeVille automobiles is an essential device that identifies the knocks in the engine and transmits signals to the PCM for proper adjustments. In this case, the sensor is usually piezoelectric, which measures the pressure spikes associated with knock using the vibrations' electrical signals. This makes it possible to fine-tune the engine for maximum efficiency, while at the same time protecting it from knock damage with even the lowest octane gasoline. VVA/VVT can change the time for each cylinder relying on the special conditions, adjust boost pressure, and let cylinders be in their premier conditions when operating at full power and longevity. Cadillac DeVille automobiles are a good example of advance technology that assists in the efficient operation of the engine through Knock Sensor.
