Sažetak
Nowadays one of the most important elements of economic and social lives is motorization. Its development is most of all accompanied by increasing the use of various means of transport, especially motor vehicles. Such a significant increase in the amount of vehicles produced can be implemented by the global use of productive materials and energy carriers, which is increasingly higher each year. Operating a higher number of vehicles causes an increase in environment pollution, not only by deleterious substance emissions, being the effect of fuel combustion, or implementation of production processes in the automotive industry, but also by a growing amount of exchanged parts and sub-assemblies and, mostly, by the rapid growth of vehicles that are withdrawn from traffic and subjected to car breaking.
The article presents a material-energy model of a motor car life cycle that can be helpful in determining the type and size of the expenditure of material and energy as well as emission loading in particular phases and the whole life cycle of a vehicle. Based on the input data contained in [9] analysis of the results of calculations related to examples of the material structure of the model vehicle from 1990 and 2000 and the impact of these changes on energy consumption and emission levels were presented.
