The Role of the Engine Valve Stem Guide

The function of the engine valve guide is to guide the movement of the valve, ensure the reciprocating linear motion of the valve, make the valve and the valve seat ring fit correctly, and transfer the heat of the valve stem to the cylinder head. The valve guide has high working temperature and poor lubrication. It is generally made of cast iron or iron-based powder metallurgy with high graphite content to improve self-lubricating performance.

Valve guide installation method: The inner and outer cylindrical surfaces of the valve guide are processed and pressed into the valve guide hole of the cylinder head or cylinder block, and then the inner hole of the hinge is finished. The matching of the positioning snap ring can prevent the guide tube from moving and falling into the cylinder during operation. Generally, there is a slight gap between the valve rod and the valve guide, so that the valve rod can move freely in the guide tube.
