摘  要:
在一台火花点火发动机上,分别进行了CO2稀释对生物质燃气中可燃组分CH4、CO和H2的燃烧及排放性能影响的试验研究。研究结果表明,稀释燃烧能够有效降低NO x排放量;适当的稀释率对发动机的平均有效压力、循环变动以及热效率的影响较小,但过大的稀释率会导致部分燃烧。通过CO2稀释燃烧的手段,可以得到生物质燃气以一定热效率和NO x排放水平为指标的适宜燃料条件范围。

摘  要:
Effect of CO2 dilution on combustion and emission characteristics of CH4,H2 and CO was analyzed in a spark-ignition engine.The results showed that dilution could reduce NOx emission.Suitable dilution ratio had little influence on brake mean effective pressure,cyclical fluctuation and brake thermal efficiency.However,excessive dilution ratio would induce to partial burn.Favorable operation range of biogas could be obtained with acceptable brake thermal efficiency and NOx emission by employing dilution combustion,which benefits for biogas application.
