• Specification

• Function

1.Guiding valve movement: The valve guide provides necessary guidance and stability for the intake and exhaust valves. It is a cylindrical metal tube pressed into the cylinder head, within which the valves move back and forth. By ensuring that the valves can move smoothly within the cylinder head during the opening and closing processes, it maintains accurate alignment, which is essential for the proper functioning of the engine's intake and exhaust processes.

2.Optimizing airflow: The accurate movement of the valves guided by the valve guide helps optimize the airflow into and out of the combustion chamber. During the intake stroke, it enables optimal airflow into the combustion chamber, which is beneficial for improving engine performance, fuel efficiency, and emissions control. During the exhaust stroke, it helps ensure the smooth discharge of exhaust gases, reducing backpressure and improving engine efficiency.
