1.前言关于陶瓷发动机的性能与可行性,在各种国际学术会议上讨论得十分活跃。去年以来,笔者先后去美国、加拿大、欧洲出席了国际会议。深感对陶瓷发动机及零件的议论与前几年相比有了质的变化。几年前,陶瓷发动机主要用部分稳定氧化锆零件组装,绝热性差,进气效率、燃烧效率等从原理上 1. Introduction The performance and feasibility of ceramic engines are discussed very actively in various international academic conferences. Since last year, the author went to the United States, Canada and Europe to attend the international conference. Deeply impressed by the discussion of ceramic engines and components compared with previous years, there has been a qualitative change. A few years ago, the main part of the ceramic engine with stable zirconia parts assembly, poor insulation, intake efficiency, combustion efficiency, etc. from the principle
