Although there are some differences between natural gas and gasoline in terms of flammability and ignition temperatures, NGVs themselves operate on the same fundamental concepts as gasolinepowered vehicles. Still, some modifications are required to make an NGV work efficiently. These changes are ...
According to NGVAmerica president Rich Kolodziej, the biggest advantage that the vehicles can offer to consumers is that they do not use any petroleum. Kolodziej asserts that natural gas produces 22% greenhouse gas emissions than diesel and 29% less than gasoline. In addition, he compares the ...
Compared to gasoline-powered cars, the natural-gas vehicles possess the unparalleled benefit of ___. A. reduction in carbon monoxide emissions B. reduction in emissions of oxides of nitrogen C. reduction in particulate matter 10 D. reduction in E. nvironmentally harmful emissions 相关...
Natural gas vehicles, or NGVs, combine compressed air, fuel, and heat to produce combustion, turning chemical energy into mechanical energy. Natural gas vehicles, or NGVs, and gasoline and diesel engine vehicles operate similarly. Still, each fuel power offers benefits, but natural gas as a tr...

Natural gas vehicles are increasingly used in Europe and South America due to rising gasoline prices. 由于汽油价格上涨,欧洲和南美的天然气汽车数量正在不断增加。 www.elanso.com 3. To develop natural gas vehicles is one of the keys to the world environment protection. 燃气汽车规模化发展问题是我国...
Natural gas vehicles (NGVs) can be dedicated to natural gas as a fuel source, or they can be bi-fuel, running on either natural gas or gasoline, or natural gas or diesel, although most natural gas engines are spark ignited. Natural gas engine technologies can differ in the following ways...
taxes. Some vehicles are either dual-fired(run on a mixture of diesel and natural gas) or bi-fuel (run on either natural gas or gasoline).Liquefied natural gas(LNG) can also be used to power NGVs, although much higher costs mean that it is currently used for only heavy-duty vehicles....
With regard to increasingly stringent emission legislation natural gas is gaining interest as an alternative fuel. Concerning mobile application natural gas is often considered to produce potentially lower exhaust emissions compared to diesel and gasoline fuel. Nevertheless, also the exhaust gas quality of...
aThe most important feature is that emissions from natural gas fuelled vehicles are less noxious than the exhaust emissions from gasoline and diesel vehicles. 最重要的特点是放射从天然气刺激的车比废气排放较不有毒的从汽油和柴油车。[translate]
