As a clean energy source, LNG is increasingly valued by the transportation industry. The LNG automobile industry has been pushed to the forefront. LNG (liquefied natural gas) heavy trucks are gaining market recognition due to their significant advantages. Some enterprises have already shown a certain scale and future. Prospects for development are promising.
LNG heavy trucks have unique advantages. First of all, it is safe and reliable. The ignition point of LNG is 230 degrees higher than that of gasoline, which is higher than that of diesel; the explosion limit of LNG is 2.5 to 4.7 times higher than that of gasoline; LNG is lighter than air, and even if it leaks slightly, it will rapidly disperse and spread, so that it will not spontaneously ignite, explode or form a fire. The ultimate concentration of the explosion. Second, clean and environmentally friendly. With LNG as the fuel for automobiles, the combined emissions of gasoline and diesel are reduced by about 85%, including 90% reduction in carbon monoxide emissions, 90% reduction in carbon dioxide, 40% reduction in particulate emissions, 40% reduction in noise, and carcinogenicity such as lead and benzene. The substance is basically free of sulfides and has excellent environmental performance. Again, cost-effective. After LNG liquefaction, the volume is reduced to 1/625 of gaseous natural gas, which saves investment, occupies less land, and has high storage efficiency. Finally, it is flexible and convenient. LNG can be transported to a region that is difficult to reach by pipelines through special tank trucks or ships. It not only saves investment compared to underground gas pipelines, but also is convenient, reliable, low risk and adaptable. National IV emission standards will be implemented soon, and upgrading heavy-duty trucks with LNG as fuel to China IV is relatively easy. It can better meet emission demand, reduce environmental pollution, and comply with national energy conservation and emission reduction policies.
