What is a knock control sensor, and how does it protect the engine?
I’ve heard about knock control sensors in performance engines. What do these sensors do, and how do they help protect the engine from damage?
What is a knock control sensor, and how does it protect the engine?
A knock control sensor, also known as a knock sensor, detects engine knocking or pinging, which is an abnormal combustion process that can damage the engine. The sensor sends a signal to the engine control unit (ECU) when knocking is detected. The ECU then adjusts the ignition timing and fuel mixture to eliminate the knocking, protecting the engine from potential damage. Knock sensors are crucial in modern engines, especially those with high compression ratios or turbocharging, where the risk of knocking is higher. By preventing knocking, the knock sensor helps maintain optimal engine performance and longevity.
