Environmental assessment of the production process of internal combustion engines

Abstract

The aim of this article is to demonstrate using the LCA methodology the environmental effects of material composition changes on Volkswagen Golf passenger cars over the past 30 years. The simplified LCA model of the engine presented in the work shows the energy consumption and total CO2 emissions based on the mass of materials. It was built to investigate general assumptions about material production and car recycling. The results of the research presented in the paper give an image of the modernity of a passenger car engine on the basis of consumption and the degree of recovery of materials used for its construction.

The material and economic assessment of the life cycle of city buses in the operational phase

“…The publication [3] presents the supporting LCA method, within which fuel consumption was calculated. The application of the LCA cycle for internal combustion engines is presented in publications [4,5]. The aim of the publication [4] was to present, using LCA analysis, the impact of changes in the material composition of engines on the environment under selected internal combustion conditions used in passenger cars.…”

“…The simplified LCA model presented in the article presents energy consumption and total CO 2 emissions on the basis of the mass of materials from which the engine is made. The aim of the publication [5] was to demonstrate the environmental impact of changes in the material composition of Volkswagen Golf passenger cars in the last 30 years using the LCA methodology. The presented simplified LCA model of an engine shows the energy consumption and total CO 2 emissions based on the weight of the engine materials.…”
