Life Cycle Assessment on the Energy Consumption and Emissions of Alternative Fuels of Automobile

ABSTRACT

With the rapid increase of vehicle population, any alternative fuel resource of automobile should be fully utilized in order to reduce the petroleum consumption and environment pollution. However, the alternative fuels should be estimated with scientific and objective methods before they are utilized. In order to study the energy consumption and exhaust emissions of the automobile alternative fuels, the energy consumption and emissions of automotive fuels were calculated and estimated during the whole life cycle. The results show that the energy consumption of diesel oil reaches minimum, the CO2 emission of ethanol, the CO of diesel oil, the NO_X of methanol, the PM_2.5 and PM₁₀ of LPG and the SO_X of DME reach minimum. The SO_X emissions of BD20 are maximum in feedstock stage. VOC emission is maximum in fuel stage. CO emission also is maximum in vehicle operation. The NO_X emissions of E90 are maximum in feedstock stage. PM_2.5, and SO_X emissions are maximum in fuel stage. CO emission is maximum in vehicle operation.
