摘要
为了研究复合增压直喷汽油机低速高负荷及外特性燃烧速度,搭建了试验平台,进行了大量性能试验,基于其他研究者的研究成果和研究经验,结合燃烧系统开发的工程性,提出了缸内层流燃烧速度和湍流燃烧速度分段分析法。通过该方法对试验结果进行分析,揭示了复合增压直喷汽油机低速高负荷及外特性燃烧速度特征。
In this paper, to research in-cylinder combustion characteristics of high load at low speed and external characteristic of a supercharged and turbocharged GDI engine, an experimental platform was set up, and lots of performance tests were finished. A new method of analyzing laminar and turbulence burning speed was shown. Through analysis of the results of the test, in-cylinder combustion characteristics of high load at low speed and external characteristic of a supercharged and turbocharged GDI engine was revealed.
