Inlet and Exhaust Valve Rocker Arm
In four-stroke cycle engines, the rocker arm of the exhaust valve is more heavily loaded. On the other hand, the force required to operate the inlet valve is comparatively less. However, it is usual practice to make rocker arms for inlet and exhaust valves identical. This results in ease of manufacturing. The main objective of the rocker arm as a ‘lever’ is to change the direction of force and not the multiplication of the effort. Therefore, the two arms of the rocker arm are often made equal in moderate and low-speed engines. In high-speed engines, the (a/b) ratio is taken as (1/1.3), where a and b are the length of the arms, a being measured towards the exhaust valve.
