The rocker arm for opening and closing the two valves located on the offset sides is 1.
On the other hand, the rocker arms for opening and closing the two valves opposite to the offset side are each composed of two independent rocker arms, and the cam shaft In contrast, a valve train for an engine is characterized in that a spark plug hole is formed on the side of a valve driven by two rocker arms.
