【摘要】 根据对氢、天然气、液化石油气、汽油和柴油理化特性的分析,以及试验结果,对气体燃料(CNG,LPG)发动机的性能进行了研究。结果表明:发动机性能很大程度上取决于燃料的理化特性。气体燃料发动机具有较好的排放性能和经济性能,气体燃料发动机动力下降的主要原因是单位体积的混合气热值较低。更多还原

【Abstract】 According to the physical and chemical properties of hydrogen,compressed natural gas(CNG),liquefied petroleum gas(LPG),gasoline and diesel oil,as well as experimental results,the performance of gaseous fuel(CNG,LPG) engines was studied.The results show that the engine performance depends to a large extent on the physical and chemical properties of fuel,and the performance(emission and economy) of gaseous fuel engine has the advantage over gasoline engine.The main reason of lower-power of gaseous fuel engine is the lower calorific value per unit volume.更多还原
