A knock sensor is a tool utilized in inner combustion engines to come across the presence of knocking, which is an atypical combustion tournament that may injury the engine. Knocking happens when the air-fuel combination within the cylinder ignites upfront, inflicting a fast build up in drive that may injury the engine’s pistons, valves, and bearings.
Knock sensors are normally fixed at the engine block or cylinder head, they usually use a piezoelectric crystal to come across the vibrations brought about by means of knocking. When knocking is detected, the knock sensor sends a sign to the engine’s digital keep watch over unit (ECU), which then adjusts the engine’s timing or gasoline combination to cut back or do away with knocking.
