【摘要】 应用密度压缩比可以真实地反映气缸内工质的压缩情况,利用它可以解释内燃机使用中用容积压缩比(或几何压缩比)不好解释的一些实际问题。应用这个新概念可为内燃机改进设计和技术改造提供一些理论依据。更多还原

【Abstract】 Density compression ratio is able to reflect the really state of the compression degree of the working medium in the cylinder. We can use it to explain some actual problems of internal combustion engines, which are hard to be explained with volumetric(or geometric) compression ratio. The application of this new conception can offer some theoretical evidence for improving design and technical reform of internal combustion engines.更多还原
