| 摘 要： | 在1台4G18汽油机上进行富氧燃烧试验,进气中O2体积分数分别为21%,23%和25%,研究了不同富氧燃烧条件下的缸内压力、瞬时放热率及THC,CO和NOx排放.研究结果表明:在汽油机中低负荷典型工况下,随着进气中O2体积分数的增加,燃烧与排放均有改善,燃烧相位提前,缸内压力峰值和瞬时放热率峰值均增大,THC,CO排放...

| Abstract: | For the intake air with 21%,23% and 25% oxygen,the oxygen-enriched combustion experiment was carried out on a 4G18 gasoline engine Under different oxygen-enriched conditions,the engine cylinder pressure,the instantaneous heat release rate and the THC,CO and NOx emission were researched.The results show that the combustion and emission improve with the increase of oxygen at low loads.In addition,the combustion phase advances,the in-cylinder peak pressure and instantaneous heat release rate increase,the THC a... |
