ENVIRONMENTAL IMPACT EVALUATION: AN INVESTIGATION OF CYLINDER ASSEMBLY AND CYLINDER HEAD ASSEMBLY OF ENGINE GROUP

摘要

Despite today’s green marketing campaigns, no engineering product is truly environmentally designed. It is necessary to know the environmental impact of a product, so that it can be developed further for the environmental design. The environmental impact of products and processes has become a key issue now. Industries have started to assess the impact of their activities on the environment. Therefore the need to assess the environmental impact of various products has been felt. The work has been carried out using the life cycle assessment. The LCA is a means of deriving a quantitative evaluation of environmental impact of product and thereby refining product quality and characteristics. It has been carried out for the two sub-assemblies of the engine group of two-wheeler Activa. Study investigates the environmental impact assessment for two main subassemblies cylinder assembly and cylinder head assembly for three main life cycle stages under the cradle-to-gate. The ecotoxicity and human toxicity have very large impact as compared to global warming, acidification and ozone depletion in both cases. The results about the selected sub assemblies of two wheelers can support the designers to develop the engine group with improved environmental impact.
