LNG在汽车代用燃料中的优势

Advantage of LNG over the Automobile Fuels

优化配件设计、合理改善油品质量和采用代用燃料是目前治理尾气污染的 3种主要途径 ,其中代用燃料在降低和控制汽车尾气污染方面效果最好。通过对LPG (液化石油气 )、CNG (压缩天然气 )和LNG (液化天然气 ) 3种代用燃料的对比分析 ,指出LPG和CNG作为汽车燃料因受其各自特性的制约 ,发展较缓 ,而LNG由于具有清洁高效、经济适用、安全度高、加气快捷、机动性强和冷能回收利用率高等优势 ,已成为当前最理想的汽车代用燃料 。

This paper points out some limits of LPG (Liquefied Petroleum Gas) and CNG (Compressed Natural Gas),compares and analyzes the properties of LNG (Liquefied Natural Gas) and other automobile fuels,such as LPG,CNG,gasoline and diesel oil.It is concluded that LNG is the cleanest,safest,most economic and available automobile fuel.It is convenient and flexible to charge LNG for LNG automobile.The cold energy of LNG can be recycled,and LNG can be easily changed to CNG in L-CNG service station.Presently,LNG is thought as the most perfect automobile fuel,and has a large market demand and good prospect.
