• Precise valve control: As a key component of the engine valve train, it can accurately control the opening and closing of the valve, ensure the accurate intake and exhaust process of the engine and maintain the normal operation of the engine.
• Closely cooperate with the camshaft, strictly follow the engine's working cycle and valve timing requirements, accurately drive the valve action, ensure the accuracy of valve timing, and make all cylinders of the engine work in harmony.
• When the engine is working, the rocker arm needs to bear a large force from the camshaft and the elasticity of the valve spring, etc., but it can work stably and reliably with its own high strength and stiffness, and it is not easy to be deformed or damaged even under the working conditions of high load and high speed.
• The head of rocker arm frequently contacts with the end face of valve stem and moves relatively, which makes it have excellent wear resistance, which can reduce wear, prolong service life and reduce maintenance cost.
• There are special lubricating oil passages and oil holes in the rocker arm, which can smoothly convey engine oil to all friction parts, realize good lubrication, reduce friction resistance and energy loss, and further improve the working efficiency and reliability of the rocker arm.
