●A rocker arm is a valvetrain component in internal combustion engines. As the arm is acted on by a camshaft lobe, it pushes open either an intake or exhaust valve. This allows fuel and air to be drawn into the combustion chamber during the intake stroke or exhaust gases to be expelled during the exhaust stroke.

The ratio of the arm length on both sides of the rocker arm is called the rocker arm ratio. The rocker arm ratio is about 1.2~1.8. One end of the long arm is used to push the valve, so that a larger valve lift can be obtained, and the push rod or lifter can be reduced. The amount of movement of the columns also reduces the inertial force generated by their reciprocating motion.
