Valve rocker bridge ‌ is an important part of the engine, mainly used to control the opening and closing of the valve. It works with the camshaft to achieve precise control of the valve, thus affecting the engine intake and exhaust process ‌. ‌ The main function of the valve rocker bridge is to connect the valve and camshaft, drive the valve rocker arm to swing up and down through the rotation of the camshaft, and then control the valve switch ‌. Specifically, the valve rocker arm acts as a mechanical transmission system in the engine, converting the rotating motion of the camshaft into the up and down opening and closing motion of the valve, so as to achieve the flow of air and fuel required for normal combustion.

‌The T-shaped rod/valve rocker arm bridge (often referred to as a "valve bridge" or "rocker bridge") is a component in an internal combustion engine's valvetrain. It serves as a connection between the rocker arms, distributing the motion from the camshaft to the valves. Its primary function is to facilitate smooth and synchronized valve operation by ensuring proper alignment and movement, thus contributing to efficient engine performance.
