摘　　要：针对汽油机瞬态工况所面临的某些问题,采用实验的手段,研究了汽油机恒转矩增转速瞬态工况下的燃烧过程.通过与稳态工况进行比较,对其示功图、平均指示压力、最高燃烧压力及其对应的曲轴转角、瞬时放热过程和累计放热过程等参数进行了分析,得出了汽油机恒转矩增转速瞬态工况下的燃烧特性.The combustion process of gasoline engine under constant torque increasing speed operating condition is studied in the way of experiment. Indicated diagram , mean effective pressure, peak cylinder pressure and its corresponding angle, heat release process were analyzed. The combustion regulations under transient condition were put forward.
