8. The fact that voltage can be created by exerting force on a crystal is used in which type of sensor?
A. Barometric pressure
OB. Throttle position
O C. Knock sensor
O D. Manifold absolute pressure

Option C

The fact that voltage can be created by exerting force on a crystal is used in Knock sensor

Explanation:

Any knock to an engine exhibits as a little shake that is distinguished by the knock sensor. This sensor acts by altering the fluctuation to an electrical sign, which is later transferred to the processor mastering the ignition system.

There the variation in quake to the voltage sign modifies the timing improvements on the kindling. The knock sensor is placed on the engine base, cylinder cap or consumption manifold. This is because its purpose is to sense fluctuations affected by engine knock or explosion.

c. magnitude and direction
