摘要
随着我国国民摩托车保有量的不断增长 ,摩托车尾气排放污染已成为城市机动车排气污染的一个不容忽视的部分。减小摩托车排气污染的理想清洁燃料首选LPG。为解决摩托车LPG发动机动力性下降的问题 ,分析了LPG的物化特性 ,并进行了LPG进气道气态喷射、进气道液态喷射和缸内液态直接喷射的对比试验。结果表明 ,液态LPG缸内直接喷射发动机的最大扭矩较燃用汽油时提高约 10 % ,能有效解决LPG常规供应方式发动机动力性下降的问题 ,具有良好的发展前景。
As the motorcycle amount increases continuously, the tail gas pollution of motorcycle becomes a non-negligible part of the tail gas pollution from city vehicles. To decrease the tail gas pollution of motorcycle, the ideal clean fuel is LPG. To solve the problem of un-sufficient power with LPG engine, the physical and chemical property of LPG is analyzed. Also, the comparing experiments are conducted for gas jet and liquid jet in the LPG-entering channel, and direct liquid jet in the cylinder. The results show with the direct liquid jet in the cylinder. The maximum torque of LPG engine is 10% more than that of gasoline engine. The technology can solve the problem of the tail gas pollution of motorcycle, and have bright future.
