Knock sensor for opel

Types of Knock Sensor for Opel

There are two types of knock sensors for Opel: copper piezo electric and semiconductor piezo electric sensors.

• Opel Knock Sensor with Copper Piezo Crystal

  This type of sensor has a copper crystal inside. The copper is shaped like a piezoelectric crystal. That means it can generate small electrical signals when it vibrates. If the engine starts making knocking sounds, the vibrations will shake the copper crystal. The vibrations will cause the crystal to shift and generate signals. The sensor's electronics constantly monitor the signals from the crystal. If the signals suddenly change, the sensor knows there is a knocking problem. It can alert the engine control unit (ECU) to take action. For example, the ECU could adjust the ignition timing to stop the knocking. This type of knock sensor is very reliable and accurate at detecting engine knocking.

• Opel Knock Sensor with Semiconductor-Piezo Electric Crystal

  This type of sensor uses special materials instead of copper for the piezoelectric crystal. It combines materials like silicon carbide or gallium nitride. These materials are better at detecting vibrations compared to copper alone. The semiconductor crystals can sense even tiny changes in the engine's sound profile. They are more sensitive to knocking noises. Like the copper sensors, the semiconductor sensors generate electrical signals when their crystal vibrates. The sensor's electronics constantly monitor these signals. If there is any sudden change in the pattern, it indicates a knocking issue. The ECU can then take preventive measures.
