Abstract:In this paper a mending method for motorcycle engine compression ratio is set up based on the analysis of local motorcycle engine"s measuring method. This paper introduces the generic concept of system project holistic design, collects and compares the displacement signals of supply valve, exhaust valve and crank by using raster displacement coder and photoelectric angle coder, finds out the relevant relation, exactly measures the parameters of valve phase, and also explains why use the liquid measure in our design. Finally we studied and found the measure system for motorcycle engine compression ratio. It easily operates and now has gained better efficiency in practice.
Key words:motorcycle engine, compression ratio, liquid measure
由于环境保护和人类可持续发展的要求，低能耗和低污染已成为摩托车发动机的发展目标, 要求发动机既要保证良好的动力性又要低油耗，摩托车的压缩比直接与发动机的功率、扭矩、油耗、排放密切相关，是影响发动机性能的一个重要结构参数［1］。...
