Multi-Zone Models of Combustion and Heat Transfer Processes in SI Engines

Popis výsledku v původním jazyce

The paper introduces recently developed toolset to be implemented into the combustion engines complex simulation codes to treat the calculations concerning the high-pressure part of thermodynamic cycle in a four-stroke spark ignition engine. This multi-zone simulating tool works on the basis of simple quasi-dimensional method reflecting the real combustion chamber geometry and uses the specific approach to describe the species chemical transformation. Here a classic kinetic scheme is combined adaptivelywith flexible method for chemical equilibrium in the cases of abnormally fast chemical reactions to improve the numerical performance of the equation system. Real 3-D combustion chamber geometry is taken into account by means of in advance created geometrical characteristics. Newly generalized tool providing these data is presented here. New code is able to work in predictive or inverse mode as well. The selected results regarding these two points are presented at the end.
