基于生命周期的轻型商用货车轻量化碳排放研究
Life Cycle-Based Carbon Emission Study of Lightweighting in Light Commercial Trucks
摘要
Abstract
This paper takes a light commercial truck as the subject of research,developing a carbon emission calculation model based on the life cycle theory.The model sets its boundaries at the stages of raw material acquisition,production and transportation,parts manufacturing and vehicle assembly in the automobile production process.The paper also explores the differences in the life cycle carbon emissions of the materials involved in the lightweighting measures,and compares the carbon emissions of the vehicle before and after lightweighting.The results show that the life cycle carbon emissions of the substitute materials such as aluminum,magnesium,and carbon fiber reinforced plastic are significantly higher than those of the substituted materials,steel and cast iron.The emissions are quantified as 6.23 kg/kg for forged aluminum,6.92 kg/kg for cast aluminum,14.76 kg/kg for magnesium products,20.2 kg/kg for carbon fiber reinforced plastic,2.85 kg/kg for ordinary steel,0.67 kg/kg for stainless steel,and 0.81 kg/kg for cast iron.After lightweighting,the carbon emissions from the powertrain system,driveline system,chassis,and body parts increased by 0.57%,525.51%,11.57%,and 33.29%,respectively,leading to a total increase in the vehicle's life-cycle carbon emissions by 36.22%.Both steel and aluminum have lower lifecycle carbon emissions,which results in more significant carbon reduction effects in the vehicle body parts before and after lightweighting.关键词
