| 摘 要： | 通过建立单缸点火式LPG发动机在GT-Power中仿真,来研究LPG组分及其比例对发动机排放的影响.仿真实验表明,LPG组分对污染物的排放有重要的影响.随着丁烷比例的增加,CO和HC的排放增加,而NO_x减少;其中,CO、HC排放最少的是Fuel 1#,NO_x的排放最低的是Fuel 3#;考虑到综合排放性能和动力性的同时,丙烷与丁烷比例为7:3时最佳.

| Abstract: | The LPG composition has a significant impact on engine performance.Changes in the ratio of propane and butane result in different proportional HC directly;then,it will effect the pollutant emissions during combustion process.According to the simulation in SI LPG engine GT-Power model,the effects of LPG composition on engine emission are studied.Results show that LPG composition has an important effect on emission.As the proportion of butane increases,CO and HC emissions increase too,but NOx emission becomes... |
