A knock sensor is a vital engine component that monitors vibrations and engine knock to improve fuel economy and performance. It's a piezoelectric sensor that converts mechanical stress into voltage, and is usually found in gasoline engines. How it works:

Detection
Mounted on the crankcase, the sensor uses piezoelectric crystals to measure engine vibrations and timings. Different degrees of compression on the crystals create varying voltage signals.

Response
The signals are sent to the engine control unit (ECU), which adjusts the ignition timing to prevent knocking or trigger a warning light.

Purpose:

Prevent knocking
Knocking, also known as pre-ignition or detonation, occurs when fuel burns unevenly in the cylinders, causing a pinging sound.

Maintain engine health
Knock sensors are essential for maintaining engine performance and longevity.

Know the condition of the engine from the spark plugs 👌

1- Good condition

2- Saturated with oil due to a problem in the piston

3- Needs to adjust the (gap) in the new spark plug

4- Evidence that the spark plugs have not been changed for long periods and needs to be changed immediately

5- Saturated with lead due to a high percentage of lead in the fuel

6- Saturated with carbon due to poor combustion, the fuel pump and air filter need to be checked

7- As a result of the engine temperature increasing above its normal rate, and therefore we check the system

8- Needs to change the type of fuel (for example, instead of 80 gasoline, it is 90 or 92 gasoline) or change the valves if it happened in a short period (less kilometers)

9- Evidence of a mechanical problem or a foreign body in the combustion chamber
