Abstract:

In the United States and Germany for example, promotion of LNG vehicle has been done for many years. It is understood, at present in the operation of LNG vehicles are mainly commercial vehicle, such as a city bus, city construction vehicles, sanitation vehicles, logistics and transportation company. The first is because the transport volume of commercial vehicle, the high usage rate, and the price is relatively cheaper natural gas fuel. Secondly, LNG had a pollution discharge smaller. A lot of particles in diesel engine emissions and pollution caused by noise pollution, smaller LNG vehicle.In the United States, using the most current LNG models is the logistics transport, in the short-distance truck use promotion, LNG car with a single cylinder vertically arranged in both sides of the frame, can choose the burning of the way, also can choose the HPDI mixed compression ignition (similar to diesel engine). For example, in short-distance vehicles UPS logistics group used most by HPDI type, type of control the diesel as pre-combustion compression ignition, ignition burning natural gas is being developed countries gradually recognized, as early as in 2011, UPS bought 48 a LNG truck and into the California Lake Ontario company.

At the same time, New York City Department of transportation also operates natural gas bus. And VerizonCommunicationsInc. in telecom enterprises and Att Corporation (AT&TInc.) is also used in natural gas powered truck.In Germany, a large logistics company -- Han Hong (Hellmann) logistics company in the fall of 2012 began using LNG as fuel for heavy truck, and for road transport 4 weeks. Since then, LNG truck also opened the German LNG logistics supplier market.The road test results show that, LNG truck can be very good to complete the task, Schenker logistics person in charge said Ren é Stocker, tested, compared to diesel car, LNG car can reduce carbon dioxide emissions to a large extent, and other harmful substances (such as carbon particles and nitric oxide and other substances) emissions almost negligible.Natural gas truck has become a new trend in the global scope, compared with traditional diesel trucks, natural gas trucks more environmental protection, lower greenhouse gas emissions, noise is lower, although the price than diesel truck high, but in the long run, the advantage of natural gas truck in oil prices rising today more and more obvious.In addition to the United States and Germany, France, Spain, the development of Holland and Portugal of natural gas vehicles are mainly concentrated in the commercial vehicles, including buses, logistics transport vehicles and garbage truck etc..
