Gasoline vehicles (GVs) emissions generally dominate ambient volatile organic compounds (VOCs) in urban areas, while VOC emissions from liquefied natural gas (LNG)-fueled vehicles play an increasingly important role in urban air quality, due to fuel transition from gasoline/diesel to alternative fuels...
Lean burn natural gas engines usually have lower in-cylinder temperatures,lower NOxemissions, higher power density, greater thermal efficiency, and better durability than their stoichiometric counterparts. In vehicle operation,natural gas vehiclesperform similar to gasoline or diesel vehicles in terms of ...
[定位] 根据题干中的the natural-gas vehicles possess the unparalleled advantage of 可以定位到第四个小标题下的第一段第一句The biggest advantage of NGVs is that they reduce environmentally harmful emissions.[精解] 题干考查与汽油动力汽车相比,天然气汽车的不可比拟的优势;题干中的unparalleled benefit与原...
Since CNG is a far cleaner fuel than gasoline, an extra advantage of the CNG Civic over the already high-reliability Gas Civic, is that it will be extremely reliable and require far less maintenance, have less wear and tear etc.One solution to the trunk space problem is to make it a ...
This makes it integral to daily life for many households and businesses. Natural gas vehicles, for example, offer similar performance to traditional gasoline and diesel vehicles, maintaining power and acceleration while providing a relatively clean alternative. ...
by natural gas. Natural gas vehicles (NGVs) produce lower levels of most pollutants than gasoline or diesel powered vehicles. The successful incorporation of natural gas engines into school buses today is largely attributed to the U.S.
Natural-gas vehicles also offer these benefits: NGVs are safer. The fuel storage tanks on an NGV are thicker and stronger than gasoline or diesel tanks. There has not been an NGV fuel-tank rupture in more than two years in the United States. ...
Natural-gas vehicles can achieve up to a 93 percent reduction in carbon monoxide emissions, 33 percent reduction in emissions of various oxides of nitrogen and a 50 percent reduction in reactive hydrocarbons when compared to gasoline vehicles. NGVs also rate higher in particulate matter 10 (PM10)...
Natural gas is unusual, a premium fuel with high value to customers but low prices at the wellhead. Because of its very low density, transportation costs are extremely high. The result is that natural gas markets developed much later than those for other fuels and regional markets remain relati...
Liquefied Natural Gas (LNG) is a type of alternative fuel that ranks second in sales to LPG in the United States. It is estimated that in 2001, about 105 million gallons of gasoline equivalent of LNG were sold for transportation purposes. ...
