- The paper presents an application of a quasi-dimensional (QD) model for the combustion simulation in a two-stroke engine. In contrast to 0D-models the QD-models provide an opportunity to describe the development of the combustion process in dependence on the actual thermodynamic state in the combustion chamber. The QD-models enable to couple the flame propagation with the combustion chamber geometry and with the flow field.An extensive sensitivity analysis is performed for the QD-model by varying the parameters of the QD-model itself and of the operating points. The constructed QD-model is examined under various conditions (engine speed, the delivery ratio and the air to fuel ratio) and shows a good agreement with experimental results.
