| 摘 要： | 以汽油机为对象，研究富氧燃烧对其指示功率、机械效率、油耗等性能指标的影响。同时考虑制氧能耗，分析汽油机富氧燃烧时的总能耗。结果表明，汽油机采用富氧燃烧可以增加指示功率，富氧1％，指示功率增长率增加4．8％；富氧燃烧可以降低汽油机油耗，增加机械效率，且设计机械效率越低，油耗降低超显著，机械效率增国幅度越大；制氧能耗对汽油机富气燃烧的总以耗有直接影响，对于给定的制氧能耗，存在相应的临界设计机械效率。得到了临界设计机械效率与制氧能耗的关系式：η0＝0．8＋0．12eNr－0．35／0．373。

| Abstract: | The characteristics of gasoline engine under oxygen enrichment combustion are investigated. The results show that the indicating power can be increased by 4.8% when the oxygen is increased by 1% in the gas inlet and that the mechanical efficiency is increased with the fuel consumption decreased under oxygen enrichment. It is also shown that the energy consumption of oxygen is important in considering if oxygen enrichment is adopted. |
