作者将一台单缸四冲程试验用汽油机改造成均质混合气压燃点火发动机。在大量试验的基础上,证明柴油均质混合气压燃点火在技术上可以实现。利用该燃烧模型进一步研究柴油机的燃烧和碳烟生成中的一些问题:如点火延迟时间与混合气浓度的关系,排气中的碳烟浓度与混合气油气当量比的关系。 The author will be a single-cylinder four-stroke test gasoline engine into a homogeneous mixture of gas-fired ignition engine. On the basis of a large number of experiments, it is proved technically that diesel homogeneous mixture pressure ignition can ignite. The combustion model is used to further study some problems in the combustion and soot generation of diesel engine, such as the relationship between the ignition delay time and the concentration of the mixture, the relationship between the concentration of soot in the exhaust gas and the equivalent ratio of the mixture gas.
