STUDIES ON INFLUENCES OF FUEL INJECTION PARAMETERS ON POLLUTANT EMISSION OF DIESEL ENGINE, USING VIRTUAL 1 ENVIRONMENT TOOL

Abstract

Virtual environment studies, represents reasonable tools for nowadays engineers, which are working in the mechanical engineering fields and not only . The advantages like: low acquisition price (comparison with experimental tools),post processing options which leads to less working time, gives engineers confidence to use this kind of tool. The paper presents studies on injection system performances(different injection pressures),and how they are influence the pollutant emission formation. Also, it was studied, which is the most opportune injection strategy, in order to achieve less pollutant emission. Virtual simulation work was done, using the AVL-Fire software, which is a CFD specialized software for calculating internal combustion engines processes. The first step was to build the combustion engine layout, after these, the input parameters were set-up, and finally simulation was run. Post-processing data, regarding pollutant emission of Diesel engine, will be presented at the end of the paper.
