What does a rocker arm do in an engine?
The rocker arm is the part responsible for transmitting the movement of the camshaft towards the intake and exhaust valves of the engine, a process that occurs through the direct contact of these parts with the tappets and according to the movement of the shaft.
How does a rocker shaft work?
Working of Rocker Arm One end of the rocker arm is connected to the pushrod. As the crankshaft rotates, it transfers rotary motion to the camshaft. When the camshaft receives power, it pushes the pushrod upward. The top of the pushrod pushes on the side of the rocker arm and turns the arm.
What do rocker arms attach to?
Rocker Arms are typically in between the pushrod and the intake and exhaust valves. They allow the pushrods to push up on the rocker arms and therefore push down on the valves. However, in Over Head Cam applications the Cam will ride directly on the Rocker Arm.
What part of a car uses a rocker arm?
Rocker arms are typically located between the pushrod and intake and exhaust valves. They are pushed and pulled by pushrods to “rock” up and down, opening and closing the exhaust valve and intake valve of the combustion chamber on engines with a camshaft below the engine.
What is a rocker on a car?

How does a lifter work in an engine?
A lifter is a cylinder that sits between a car’s camshaft and the cylinder valves. As the camshaft moves over the top of the lifter, it actuates, temporarily opening the valve. And because the intake and exhaust valve need to open at different times, each has its own separate lifter.

What is the function of valve lifter?
The basic function of a valve lifter is fairly simple. It sits on the camshaft and transfers the motions of the cam lobe up through the pushrods and rockers to open and close the valves. The size and shape of the cam lobe under the lifter (multiplied by the ratio of the rocker arms) determines valve lift and duration.
