Working Principle
The rocker arm shaft serves as a critical support component in the engine's valve train system:
Pivot Support: Provides stable rotational axis for rocker arms
Power Transmission: Transfers cam lift motion to valve stems
Lubriion Passage: Features internal oil passages for bearing lubriion
Positioning: Ensures correct rocker arm positioning for precise valve timing
