Potential of a Natural Gas Vehicle as EEV 2000-01-1863

The natural gas vehicle has high potential as an Environmentally Enhanced Vehicle (EEV). In order to achieve low-emissions, a precise gaseous injection system coupled with optimized feedback control is necessary for the natural gas engines. An advanced natural gas vehicle, such as the Honda Civic GX, can meet the Super-Ultra-Low-Emission Vehicle (SULEV) emission standard in California and also meet the future European & Japanese emission standards. The low-emission natural gas vehicle emits very low off-cycle emissions, air toxic emissions and has zero-fuel evaporative emissions. The use of natural gas-based fuels achieves CO₂ emission reductions relative to use of petroleum-based fuels. Low-emission NGVs are attractive for use in urban and metropolitan city centers to reduce smog.
