摘　　要：提出汽油发动机富氧燃烧技术,在单缸化油器式汽油机上进行富氧燃烧实验。利用燃烧分析仪对富氧燃烧发动机的燃烧特性进行分析,实验结果表明进入气缸助燃的空气中氧气浓度增加到24%时,气缸压力升高,最大压力发生时刻提前,燃油放热增加,开始放热时刻提前,燃烧过程的循环变动量降低,燃烧过程的稳定性提高。In this paper, oxygen-enriched combustion technique was proposed, and the experiment was done on the single cylinder gasoline engine with carburetor. An investigation of oxygen-enriched combustion on the combustion performance of the gasoline engine was carried out. As the oxygen content of the combustion air increases to 24% , the engine cylinder pressure increased, the moment of the maximum pressure happened in advance. The heat-released rate was increased, and the moment of the heat released was advanced too. The alteration rate was lower, and the combustion stability was increased.
