压缩天然气作为汽车燃料的特点及经济性分析

The characteristics and economic analysis on compressed natural gas using as automobile fuel

天然气应用在车用燃料领域主要有2种形式,1种是压缩天然气,另1种是液化天然气。2种燃料的区别在于前者储存带压的气态甲烷,不需要气化直接燃烧提供动力,而后者储存液态低温甲烷,须将其气化后燃烧提供动力。文中阐述了压缩天然气作为汽车燃料的特点,对不同汽车用燃料进行了经济性分析。

Natural gas is used in vehicle fuel field in 2 forms, compressed natural gas(CNG)and liquefied natural gas(LNG). The difference between these 2 fuels is that the former is stored under pressure of gaseous methane, and doesn’t need gasification and can be directly burned to supply power, but the late is stored with liquid-state low temperature methane and need to be gasified to burn to supply power. The characteristics of compressed natural gas using as automobile fuel is described and the economic analysis on different types of automobile fuels are conducted.
