摘要：
A whole life cycle material, energy consumption and emissions evaluation model of automotive products was established. The model covered the entire closed-loop life cycle stages of automotive products from material acquisition, material processing, part processing and manufacturing, vehicle assembly, operation and use until recycling. The conventional gasoline vehicles manufactured by a company and pure electric vehicles developed on the same platform were selected for comparative analysis by using the evaluation model. The results show that in comparison to the conventional gasoline vehicles, the life cycle energy consumption and the life cycle emissions of CO2, CH4, N2O and NMVOC are all lower, while the life cycle emissions of CO, SOx, NOx and PM are higher for pure electric vehicles. The life cycle impact assessments of two type vehicles were also evaluated by using the CML 2001 model. The results show that the abiotic depletion potential(ADP) of pure electric vehicles is significantly higher than that of conventional gasoline vehicles, due to more use of high scarcity metals copper and lithium on pure electric vehicles. Although pure electric vehicles performed better than conventional gasoline vehicles in terms of the global warming potential(GWP), pure electric vehicles are still inferior to conventional gasoline vehicle as far as the indices of health toxic potential, photochemical ozone creation potential and acid potential are concerned. © 2019, China Mechanical Engineering Magazine Office.
