| 摘 要： | 在一台单缸火花点火发动机上开展了燃用不同组分配比的沼气模拟气体的掺氢混合气的燃烧稳定性试验研究.研究结果表明:在15%～35%的掺氢比范嗣内,随着混合气中掺氢比的增加,发动机循环变动变小,燃烧稳定性提高.掺氢导致平均指示压力的循环变动系数减小,燃烧放热率加快,火焰发展期缩短.其中35%掺氢比的混合气比15%掺氢比的混合...

| Abstract: | Experimental study on combustion instability of a spark-ignited single-cylinder engine fueled with biogas and hydrogen is conducted.Result shows that at hydrogen fractions of 15 percent to 35 percent in the fuel blends,the engine operating stability is increased and cyclic variations are decreased.Hydro-gen addition decreases the coefficient of variation of indicated mean effective pressure,increases heat release rate and shortens flame development duration.Coefficient of variation of indicated mean effecti... |
