Technical Critical Analysis of High Temperature Self-lubricating Valve Actuating Mechanism Materials of Engine

The high temperature self-lubricating valve actuating mechanism is the key part of an engineering engine. In this paper, author has made progress in technical analysis of all research process for the three kinds valve actuating mechanisms, and detail description and comparison of the physico-meehanical properties, horse power test, materials preparation, and combined performance of the three valve actuating mechanisms are also given. Author has certified his viewpoint from applied aspects.
