Gasoline–ethanol fuelCompressed natural gas fuelFlex-fuel vehiclesEmissionsFuel pricesA comparison of the emissions of gasoline–ethanol fuel and compressed natural gas (CNG) fuel used in vehicles with spark ignition engine was done. Emission tests were carried out on 99 vehicles in Rio de Janeiro...
Regarding future emission legislation the potential of diesel, gasoline and natural gas fuels will be evaluated. New technical solutions will be taken into account and their impact on fuel consumption will be estimated. 展开 关键词: Exhaust emissions Fuels Natural gas Diesel fuels Gasoline Alternative...
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]
The engine did not meet the emissions standards for 2010 on gasoline for this testing. Catalyst degradation from misfires while setting up the engine to operate on gasoline contributed to the higher than expected emissions. 展开 关键词: Lean burn engines Exhaust gas recirculation (EGR) Natural ...
Natural gasinternal combustionengines are technologically mature and produce lesstoxic airemissions than gasoline anddiesel engines. In 2008, there were 9.6millionnatural gas vehicles(NGVs) worldwide. Pakistan had the most (2.0million), followed by Argentina (1.7million), Brazil (1.6million), Iran ...
natural gas has a lower energy density and therefore needs a larger additional tank than LPG to do fewer miles, although it has a higher octane rating of up to 130 (petrol is typically 92–98) and a slight emissions advantage over LPG. It is stored at 200bar (another reason for the ...
However, natural gas occupies a larger volume in the cylinder than liquid fuels, reducing the number of oxygen molecules (share of air in the cylinder), which reduces power. The net effect on natural gas power vs. gasoline is relatively neutral. However, since it is a gaseous fuel at ...
Natural-gas vehicles also offer these benefits: NGVs are safer. The fuel storage tanks on an NGV are thicker and stronger than gasopne or diesel tanks. There has not been an NGVA.comparatively low price of fossil fuelsB.reducing less harmful emissionsC.difficult tasks to design, develop and...
Regarding cost, both LNG and CNG are generally more economical than gasoline, considering current market prices. Advantages of CNG Cars Fewer Emissions - Natural gas emissions don’t impact the environment and climate as negatively as other fuels because natural gas burns cleaner, making NGVs enviro...
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. ...
