摘要: 将一台4气门汽油机改装为燃用M100甲醇发动机,测量了甲醇发动机的动力性、经济性参数,研究了M100甲醇发动机性能随过量空气系数、点火提前角的变化规律。结果表明:转速为2 500 r/min、 部分负荷工况时,当过量空气系数一定,随点火提前角的增加,甲醇发动机的转矩增大,当量燃料消耗率下降,NO排放升高80%以上;相同工况时,当点火提前角一定,随过量空气系数的减小,发动机转矩增大,HC、CO排放明显增加。与燃用汽油相比,M100甲醇发动机外特性上的最大转矩增加约5.2%;在城市道路常用转速2 000 r/min,甲醇发动机按负荷特性运行,当量燃料消耗率低于原汽油机。

Abstract: The effects of excess air ratio and ignition timing on engine torque and break specific fuel consumption of a methanol engine transformed from a gasoline engine are studied, and the performance of M100 methanol engine is experimentally investigated. Results show that the engine torque increases with the increase in advanced ignition angle for a specified excess air ratio at 2 500 r/min, and the NO emission is increased by 80% when the fuel consumption decreases. When the excess air ratio decreases at a specified ignition time,the engine torque increases, and HC and CO emissions are significantly increased. The maximum torque is increased by 5.2% higher than that of original gasoline engine, and the brake specific fuel consumption is lower at speed of 2 000 r/min.

Key words: power machinery engineering, methanol, advanced ignition angle, excess air ratio
