本文系汽油机燃烧系统改进的研究报告之一。文章在分析我国汽油机现状的基础上,提出改进汽油机燃烧系统的途径;介绍了一种稀薄混合气燃烧技术,即增加点火系统容性放电成分来提高点火能量,改善燃烧状况所取得的成果。在我国汽车保有量中,汽油机汽车占有很大的比重。根据我国石油资源和燃料分配政策,今后装有汽油机的汽车仍然占有较大的比重。我国汽车工业发展的现阶段,从节能和降低排气污染的角度出发,深入开展汽油机燃烧系统的研究和尽快地推广应用汽油机燃烧过程的研究成果,对国民经济的发展,节约能源和控制排污、净化环境等方面,具有特别重大的意义。
This article is one of the research reports on the improvement of gasoline engine combustion system. Based on the analysis of the status quo of gasoline engines in our country, the paper proposes ways to improve the combustion system of gasoline engines. A lean mixture combustion technology is introduced, which is to increase the ignition energy and improve the combustion conditions by increasing the capacitive discharge components of the ignition system. In our car ownership, gasoline engine cars account for a large proportion. According to China’s oil resources and fuel distribution policy, cars equipped with gasoline engines will still occupy a larger proportion in the future. At the present stage of the development of China’s auto industry, from the perspective of energy saving and emission reduction, the research on the combustion system of gasoline engine is carried out in depth and the research results of the combustion process of gasoline engine are popularized and applied as soon as possible. The research on the development of national economy, energy conservation and pollution control, Purification of the environment, has a particularly significant significance.
