气体燃料作为能源替代应用于内燃机时,会因其组分、温度的原因对内燃机充气效率产生影响。讨论了四种气体燃料对内燃机充气效率的影响,并基于一些基本假设,从理论上计算了影响的程度。结果表明,LPG燃料对充气效率的影响较小,氢气较大;气体燃料掺燃量越大,对充气效率的影响越大;过量空气系数大的内燃机所受到的影响较小。研究的四种气体燃料因温度对充气效率无影响或影响较小。

As alternative fuels,gaseous fuels will have an impact on volumetric efficiency when they were used in the internal combustion engines,because of their composition and temperature.This paper discusses the impact of four types of gaseous fuels on the volumetric efficiency in internal combustion engines,and based on some basic assumptions,calculates the degree of impact in theory.The results showed that the impact of LPG on the volumetric efficiency smaller and hydrogen larger;The impact on the volumetric efficiency larger with gas mixed with fuel increases;The impact on the volumetric efficiency smaller with the excess air ratio of the internal combustion engines larger;The temperature of four types of gaseous which research in this paper,makes no or less impact on the volumetric efficiency.
