摘要
配气正时是影响发动机性能的重要技术参数。本文分析了迸行配气正时动态测定的必要性,介绍了我们研制的配气正时仪及对发动机进行动、静态测定的情况。在对测定结果分析的基础上提出了影响配气正时变动的主要因素。
Valve timing is an important parameter for the performance of internal combustion engine. This paper analysed the necessity of dynamic valve timing measurement and introduced the principle of the instrument developed by us to measure static and dynamic valve timing. By the analysis of the measuring results, the basic factors which would change valve timing were given.
