摘要
介绍了应用于汽油发动机的喷水技术发展历程及喷水技术的分类,阐述了喷水技术对汽油发动机燃烧性能和排放性能的影响。发动机2000rpm,50%负荷工况下进行了进气道喷水的试验研究,结果表明喷水技术能够提高发动机有效热效率,降低油耗和爆震趋势,并减少NOX与碳烟排放,但增加未燃HC排放。
The development history of water injection technology applied to the gasoline engine and the classification of water spray technology are introduced.The influence of water injection technology on the combustion performance and emission performance of gasoline engine is expounded.And the experiment was conducted on the engine under 2000rpm and 50% load condition.Water injection technology can improve the effective thermal efficiency of the engine,reduce fuel consumption and knocking trends,and reduce NOX and soot emissions,but will increase unburned HC emissions.
