| Abstract: | The reasons for the early wear of valve stem end in engine were studied in this paper through a real engine.Surface hardness,roughness,machinework marks and material components were found to be the major reasons of the early wear by means of a large number of analysis,investigations and tests.Some measures of improving the early wear of valve stem end were proposed and their validity was verified by vehicle and engine tests,and these measures have been applied in production. |
