The results of study show that the transmitting speed of flame is slower and the combustion duration is longer than gasoline. the combustion status of lpg is improved, but the problem of long combustion duration also exists when speed and load are increased. it is useful to adjust ignition timing, but nox emission increase
通過研究認識到: lpg燃燒時火焰傳播速度比汽油慢,燃燒持續期比汽油長;隨著轉速和負荷的增大, lpg燃燒狀況得到改善,但仍出現后燃期長,熱量利用不充分等問題;點火提前角的調整有利於lpg的燃燒,但使nox排放升高。
