The valve stem oil seals are assembled on the duct of the in-exhaust valve to prevent
overfull lubricating oil from entering the cylinder and combustor. They can reduce the
amassment of carbon on the valve, improve the performance of the engine and reduce the
environmental pollution caused by waste gas and save oil. In order to lubricate the duct
and stem??it needs to be lubricated slightly, so they are called sealing of
controlling volume of flow.
