Research

The purpose of the research unit is to perform fundamental studies, to improve the understanding of physical and chemical process occurring in an internal combustion engine, and applied research, to provide computational tools which can help the design of future engines.
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 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. Therefore the fundamental issues are the prediction and control of i.c. engine emissions and consumptions by means of innovative 1D and multiD thermo-fluid dynamic simulation codes.
