摘要
气门作为发动机配气机构中的执行元件,工作时长期处于高温、有害气体腐蚀及反复的冲击载荷作用下,其工作环境十分恶劣。由于其担负的特殊功用和恶劣的工作条件,气门失效时有发生。文章介绍了12种气门常见的几种失效模式及表现形式,并从气门加工、热处理过程、组装及使用等几方面对气门失效情况进行了分析,并提出了相应对策。
Valve used as an actuator in the valve train of engine, its working environment is very baddue to high temperature, corrosion of harmful gas and repeated shocking for a long time. The valve often doesn＇ t work because of its special function and badly working environment. This paper introduces several cases for the valve without any effects, and also analyzes cause of valve inefficiency from valve manufacturing, heat treatment, assembling and use, and gives some relative measures against above mentioned valve inefficiency.
