LNG (liquefied natural gas) used as a vehicle fuel, has much advantages such as low stored-pressure, high energy density, long renewal-travel-distance, and clean exhaust gas-emission. So its safe, efficient, economic and environmental advantage attract more and more attention from automobile industries in recent years. This article compares LNC with CNC (compressed natural gas) about their strengths and weaknesses, summarizes the advantage of LNC vehicle, and furthermore, analyzes the development prospect of LNC vehicle.%LNG(液化天然气)用作车用燃料,具有储存压力低、能量密度高、续驶里程长、排放尾气清洁等优点,其安全、高效、经济、环保优势正越来越受到我国汽车工业的青睐.本文通过对比车用燃料LNG和CNG(压缩天然气)的优缺点,总结了LNG汽车的发展优势,并分析了LNG汽车的发展前景.
