*The rocker arm in the car is actually a double-arm lever, used to change the direction of the force transmitted by the push rod, and act on the end of the valve rod to push the valve open.

*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.
