As a vehicle fuel, LNG (liquefied natural gas) has higher octane number, better antiknock performance, less engine loss, lower fuel cost and better environmental protection performance compared with traditional fuel oil. Therefore, the development and application of LNG commercial vehicles have been greatly promoted abroad.
Widely used in commercial vehicles
In the United States and Germany, for example, the promotion of the LNG car has been going on for many years. It is understood that the current operation of LNG vehicles are mainly commercial vehicles, such as urban public transport, urban engineering vehicles, sanitation vehicles, logistics and transportation companies. First of all, because commercial vehicles have a large amount of transportation, high utilization rate, and natural gas prices are cheaper than fuel. Second, LNG cars have less pollution emissions. Compared to diesel engine emissions of large particles and noise pollution, LNG vehicles pollution is less.
In the United States, the current use of LNG models is the largest logistics vehicles, in short heavy truck use, LNG car with a single cylinder vertical in both sides of the frame, you can select a combustion mode, can also choose HPDI HCCI mode (similar to diesel engine). For example, in the short distance vehicle UPS logistics group of the most used HPDI type control, this type of compression ignition, ignition diesel as pre ignited natural gas is gradually recognized by the developed countries, as early as in 2011, UPS bought 48 LNG trucks and into the California Lake Ontario company. At the same time, the New York City Department of transportation also operates natural gas buses. And telecom companies Verizon, Communications, Inc. and Att Corporation (AT&T Inc.) are also using natural gas as the driving force of the truck.
In Germany, Hellmann, a large logistics company, began testing LNG fuel heavy trucks in the autumn of 2012 and carried out road transportation for 4 weeks. Since then, LNG trucks have also opened the German LNG logistics supplier market.
The road test shows that LNG truck can complete the task well, Schenker logistics director Ren Stocker said the trial proves that compared to diesel vehicles, LNG car can reduce carbon dioxide emissions to a great extent, and other harmful substances (such as carbon particles and nitric oxide and other substances) emissions can be ignored.
Natural gas trucks have become a new trend in the global scope, compared with conventional diesel trucks, natural gas trucks are more environmental protection, greenhouse gas emissions, lower operating noise is lower than the price of diesel trucks, although high, but in the long run, the advantage of natural gas trucks in oil prices rising today will become the more obvious.
In addition to the United States and Germany, countries such as France, Spain, Holland and Portugal also focus on commercial vehicles, including buses, logistics vehicles and garbage trucks.
Policy guarantee, LNG automobile promotion
Similar to our country, the promotion of natural gas vehicles through policy support is also one of the means of some countries. For example, through the reduction of taxes and fees and subsidies to achieve the purpose of promoting LNG vehicles. In Sweden, the road tax paid by natural gas vehicles is about 3000 kroner (about 2862 yuan) less than diesel cars. In Sweden's capital Stockholm, Monday to Friday 18:30 to 6:30, each car import vehicle in the city to pay traffic fees, but natural gas vehicles and other energy-saving vehicles are exempt from blocking the fare, each green car per year can save about 14400 kronor. In Pakistan, the customs office will exempt the imported natural gas equipment, vehicles and refitted parts, and the tax authorities will exempt the natural gas cars from the sales tax. In Bangladesh, imported gas stations, equipment, modifications and natural gas vehicles are exempt from tax policy, and banks and leasing companies can provide loan support for the modification of natural gas vehicles. The Asian Development Bank has helped the Bangladesh capital Dhaka purchase l million sets of natural gas vehicle modifications and car cylinders. There is Thailand, not only for the natural gas engine, and the original vehicle parts implement preferential tax policies, tax rates fell from 20% to 40%, finally fell to 0%, and each converted a natural gas vehicles, the Thailand government will subsidize 10 thousand baht (about 2122 yuan).
In the process of developing natural gas vehicles, Croatia has made a new exploration in the form of organization, which provides a reference for other countries. In 2009, Croatia established the "environmental protection and energy efficiency fund" financing institutions". After the establishment of the institution, mainly through two measures to promote the development of clean energy automotive industry. One is through the management of toll fee, traffic control, transport of goods within the city and city traffic facilities construction, improve transport system application of alternative fuel and fuel cell, so as to promote the development of the clean automobile project; LNG and CNG used in automobile industry, taking the priority of public transport services, taxi, driving and public service; support the new LNG and CNG gas station construction through financial means. The other is through the cooperation with the Ministry of ocean, transportation and infrastructure, as well as the Ministry of economy, labor and enterprise, to carry out the transport plan to reduce environmental quality". The program's main job is to replace environmentally friendly passenger cars, trucks and school buses, and provide 50 thousand pools (about 6750 euros) of subsidy for each vehicle through financing institutions.
The quantity of filling stations is limited and the application of LNG vehicles is limited
And our country is same, the construction of filling station is insufficient, it is the important factor that restricts the development of LNG vehicle. The United States is the world's second largest producer of gas, and research and development of LNG technology has emerged in 1930s. But according to the American energy information administration
