The Investigation on Unburned Hydrocarbon Emissions in Spark Ignition Engines

本文归纳了作者在攀登计划中所从事的研究工作，详细介绍了本课题的研究内容及研究成果，它包括火焰淬熄机理，狭缝与火焰传播，碳氢的形成机理和主要生成源，各主要生成源所占比例，碳氢预测模型，影响因素。

This paper summarizes the research work supported by national fundamental key project. It introduces the research contents and main achievements of this project in details including the mechanism of flame quench, flame propagation and crevices, the formation mechanisms of hydrocarbons and their major sources, the fraction of those major sources which contribute to the exhaust hydrocarbon emissions, the prediction models of hydrocarbon, the influencing factors and the reduction methods of hydrocarbons etc.
