Current State of Our Model of Processes in a Combustion Engine

Popis výsledku v původním jazyce

The contribution is devoted to presentation of the current state of modelling of processes in a combustion engine at the Department of Modelling of Processes of the Technical University of Liberec. The main motivation of working on the model is a task ofmodelling of production of nitrogen oxides in a gas combustion engine. We decided to develop a complete model of relevant physical and chemical processes and compute the nitrogen oxide production as an outcome from it. The model is built modularly fromthree relatively independent sub-models of compressible flow, mass & energy transport, and chemical reactions. The most interesting aspects of the problem are time-depending space (volume change of the cylinder) and application of the Mixed-Hybrid FiniteElement Method to the problem of compressible flow. Not all problems are solved, but all the sub-models are built in at least basic version and they are connected in an action complex allowing to test and to develop all its parts.
