CONSTRUCTION
The width, diameter and thickness of the rollers of the valve rocker arm sub-assembly are optimized, achieving weight and friction reduction.
An oil delivery pipe method is used to supply lubricant to the valve rocker arm sub-assembly. As a result, reliability is ensured by using a method where lubricant can be efficiently supplied from the upper portion of the camshaft to the sliding parts.
