摘要

在一台火花点火天然气发动机上开展了不同掺氢比φ(H

)和废气再循环率φ下发动机性能和排放的实验研究.研究结果表明:引入废气再循环(EGR)会使发动机功率降低

但掺氢可以提高大φ值工况下的发动机功率.有效燃油消耗率随φ 的增大呈现先减小后增大的趋势

在φ为5%时达到最低

有效燃油消耗率随φ(H

)的增大而降低.天然气掺氢后NO

排放增加

引入EGR使NO

排放得到降低

此降低效果在大掺氢比情况下更为显著.在φ较大时

天然气掺氢具有较好的效果.HC和CO排放随φ 的增大而增加

随φ(H

)的增大而降低.当φ为 10%、φ(H

)为20%时

发动机可获得较好的综合性能.

Abstract

An experimental study on the performance and emissions of a spark ignition engine with natural gas-hydrogen blends combined with EGR was conducted. The results show that the engine power output decreased with the increase of exhaust gas recirculation ratio(φ)

and hydrogen enrichment at a considerable φ could improve the engine power output. Brake specific fuel consumption decreased first and then increased with the increase of φ

and its value was minimum when φ=5%. Brake specific fuel consumption decreased with the increase of hydrogen fraction. For a specified hydrogen fraction

concentration decreased with the increase of φ

which was more obvious at high hydrogen fractions. HC and CO emissions increased with the increase of φ and decreased with the increase of hydrogen fraction. The highe

r performance and the lower emissions of the engine could be obtained when φ(H

)=20% and φ=10%.
