Abstract

A method for preparing valve lifter of air door on combustion engine includes applying carbonized steel or iron ball being chill ¿C treated as valve lifter body material and applying Man steel or Cr steel with high antifriction property as chassis material, welding two said components prepared by different materials together to form an integral body.

Description

[0001] Technical collar: [0002] The invention relates to a valve mechanism of an internal combustion engine, in particular to a valve tappet of an internal combustion engine and its processing technology. Background technique: [0003] The valve mechanism of the internal combustion engine is an important part of the entire gas distribution system. According to the different types of engines, one is that the valve is driven by a cam to drive the tappet, and then the tappet pushes the valve; the other is that the cam drives the tappet, push rod and The rocker arm pushes the valve. Regardless of the driving method, the cam directly rubs against the tappet. The current tappet body and the chassis are processed into one piece of metal material. Over time, with the wear of the tappet, the valve clearance gradually increases. , affecting the efficiency of the engine. Invention content: [0004] The purpose of the present invention is to solve the problem that the valve lifter o...
