It can exist used in the internal combustion engine of motorcycles, automotive, and other flying machines. There are several rocker arms in a car'due south engine. And they work in conjunction with each other. So most times, when 1 rocker arm is faulty, information technology affects the others.

Every car'southward engine has a particular number of rocker arms it needs to function. For example, a V8 has 8 cylinders with ii rockers attached to each making it a total of 16 rocker artillery. And then, how many rocker arms are in a V6? A V6 engine has 6 cylinders with two rocker artillery on each cylinder. In a nutshell, a V6 has a total of 12 rocker artillery.
