The purpose of the research unit is to perform both fundamental studies, to improve the understanding of physical and chemical processes occurring in the internal combustion engines, and applied research, to provide computational tools which can help the engine design. All the areas of research are in the field of numerical modeling, regarding the development of advanced 1D and multiD fluid dynamic models for the calculation of the in-cylinder combustion process and the pollutant formation and for the simulation of the unsteady flows in the complete intake and exhaust systems, including catalytic converters, diesel particulate filters, DeNOx traps and silencers. The goal is the prediction of the pollutants discharged by modern engines (Otto, Diesel, HCCI) and of the fluid-dynamic, chemical and thermal behaviour of the exhaust gas after-treatment system; this is achieved by means of innovative 1D and multiD thermo-fluid dynamic simulation codes.
