天然气客车发展迅速 配套环节亟待同步

The Full Complement of Support Should be Reinforced for Fast Development of LNG Bus

作为汽车燃料时，每1kg的LNG可以替代1．25kg的柴油；相比燃油，LNG汽车排放的尾气中，碳氢化合物减少72％，NOx减少39％，CO减少90％，SOx和Pb降为0。据北京市相关部门测算，LNG车辆PM2．5排放量比柴油车降低超过90％。如果将全北京市1．57／辆燃油公交车改为LNG车辆，相当于改造75万辆小汽车，对改善首都大气环境、降低PM2．5排放意义十分重大。

With more than 20 years history of development in China, LNG bus has a great potential in the effort of energy-saving and emission-reducing. Since beginning of 2012, the government had issued a series of practical guiding lines that is providing favorable developing opportunities for LNG bus industry. Though LNG technology has been somehow in quite mature stage, there still exists this or that issues that need to be solved in reality.
