【摘要】：该文构建了考虑报废回收环节的汽车发动机全生命周期环境影响评价模型,并选取某企业生产制造的某款发动机作为实证研究对象,采集清单数据代入模型计算包括报废回收阶段在内的发动机全生命周期环境影响潜值,根据结果可分清全生命周期各阶段的责任,综合各种因素对一些主要贡献指标做到有的放矢。研究结果表明,材料回收再利用省去了原材料开采、冶炼等诸多环节,可有效降低发动机对生态环境的影响;未来轻量化、再制造、材料再循环等绿色技术路径是发动机节能减排的重要手段,通过形成减量化、再制造、再使用、再利用的4R循环体系可更加有效地挖掘出发动机的全生命周期节能减排潜力。
[Abstract]:In this paper, an environmental impact assessment model for the whole life cycle of an automobile engine considering scrap recovery is constructed, and an engine manufactured by an enterprise is selected as an empirical research object. Collecting inventory data into the model to calculate the environmental impact potential of the whole life cycle of the engine, including the end-of-life recovery phase, and according to the results, the responsibilities of each stage of the whole life cycle can be distinguished. Comprehensive a variety of factors to some of the main contribution indicators to achieve a targeted. The results show that material recovery and reuse can effectively reduce the impact of the engine on the ecological environment and reduce the impact of the engine on the ecological environment, thus effectively reducing the impact of the engine on the ecological environment and reducing the amount of light and remanufacturing in the future. The green technology path such as material recycling is an important means of engine energy saving and emission reduction. The 4R cycle system, which is formed by reducing, remanufacturing, reusing and reusing, can more effectively excavate the full life cycle energy saving and emission reduction potential of the engine.
