摘要
液化天然气(LNG)作为汽车用燃料,其突出优点是绿色环保,能量密度大(约为CNG的3倍),气液体积比为625/1,汽车续驶里程长,液化天然气气瓶是一种可以将LNG保持在-161℃左右较长时间的真空绝热容器。应市场需求国内LNG车用瓶,已由原最大容积500 L提高至950 L,这也证明我国LNG车用瓶技术步入一个更高的水平。
The outstanding advantage of liquefied natural gas（LNG） as vehicle fuel is that it is an environmentally friednly energy with high energy density（about three times of CNG） and high gas-volume ratio（625/1）, which allows better cruising capability. Liquefied natural gas cylinder is a vacuum insulated container that maintains LNG at-161 ℃ for a long time.According to the market demand, the maximum volume of domestic automobile LNG cylinder has been increased from 500 L to 950 L, which also demonstrates that automobile LNG cylinder technology in china has stepped into a higher level.
