Environmental emissions and energy consumptions assessment of a diesel engine from the life cycle perspective

摘要: As environmental awareness increases, industries and businesses are becoming concerned about the issues of natural resource depletion degradation. Life Cycle Assessment (LCA) enables estimation potential materials energy resources required for emissions resulting from activities in our economy. The present study intends to quantify consumption entire life cycle a newly manufactured diesel engine produced Chinese factory determine stage with largest impact. Quantitative results impact indicators each unit process achieved by LCA method using core database. Logarithmic processing is conducted order normalize result more tractable range. show that Primary Energy Demand, Global Warming Potential Photochemical Ozone Formation three predominant impacts along engine, which account 50.37%, 19.47% 17.54% total impacts, respectively. usage consumes maximum brings followed raw material acquisition components manufacturing.
