现在和将来柴油机的发展趋势是提高性能要求和延长工作寿命。活塞环和气缸套是往复式发动机的重要零件,解决它们在变工况条件下的匹配性是对实现这种发展趋势的一个重要贡献。本文将讨论Perfect Circle分公司为满足这些要求所作的工作。本报告包括在部件试验台上进行匹配性试验的结果和随后在发动机上进行考核试验的结果。对活塞环表面喷涂材料的切实可行的观点及其对延长发动机寿命的可能性是本文的重点。
The current and future trends in diesel engines are to improve performance requirements and extend working life. Piston rings and cylinder liners are important parts of reciprocating engines. Solving their matching under varying working conditions is an important contribution to achieving this trend. This article will discuss what Perfect Circle did to meet these requirements. This report includes the results of a compatibility test performed on a component test stand and the results of subsequent tests performed on the engine. A practical view of the material being sprayed on the piston ring surface and its potential for prolonging the life of the engine are the focus of this article.
