中文摘要：天然气应用在车用燃料领域主要有两种形式。一种是以压缩天然气CNG（Compressed Natural Gas）为燃料的汽车，称为“CNG汽车”；另一种以液化天然气LNG为燃料的汽车，称为“LNG汽车”。两种汽车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。本文重点收集整理了CNG在运输行业节能环保方面的贡献，对比了不同运输方式的经济性，供读者参考。
英文摘要：There are two main ways: One is based on compressed natural gas CNG (Compressed Natural Gas) fueled vehicles, called "CNG vehicles"; another LNG LNG-fueled vehicles, called "LNG cars." Difference between the two ways are that the former car gaseous methane is stored under pressure and does not require direct combustion gasification to power, while the latter low temperature storage of liquid methane, shall after its regasification combustion powered. This article has collected and compiled contributions made by CNG to energy saving and environmental protection of transportation industry and made few comparisons of different mode of transportation tools for readers.
