作为车用燃料,LNG与传统燃料相比具有辛烷值高、抗爆性能好、燃料费用低、环保性能好等优点。因此在国外,LNG商用车的研发和应用很早就得到了大力推广。多用在商用车领域以美国和德国为例,LNG汽车的推广已经进行多年。据了解,目前,两个国家在营运的LNG车辆以商用车为主,例如城市公交、工程车辆、环卫车辆、物流运输车辆等。究其原因,首先是商用车的运输量大,使用率高,且天然气价格相对燃油更便宜。其次,LNG车更加清洁。相比柴油发动机排放的
Compared with traditional fuels, LNG has the advantages of high octane number, good antiknock performance, low fuel cost and good environmental performance as vehicle fuel. Therefore, in foreign countries, the research, development and application of LNG commercial vehicles have long been promoted vigorously. Multi-use in the field of commercial vehicles in the United States and Germany, for example, the promotion of LNG vehicles has been for many years. It is understood that at present, LNG vehicles operated by both countries are mainly commercial vehicles, such as urban public transport, engineering vehicles, sanitation vehicles, logistics and transport vehicles. The reason, first of all, the volume of commercial vehicles, high utilization, and the relative price of natural gas is cheaper fuel. Second, LNG cars are cleaner. Compared to diesel engine emissions
