The The paper presents results of numerical simulations of combustion processes inside a piston engine with spark-ignition. The simulation was performed using ANSYS Fluent. For simulation of the combustion process, a new model of combustion, being an extension of a model available in the software, taking into account gas recirculation was proposed. This model was then implemented in the program Fluent by means of the User Defined Scalars and User Defined Functions. As the object of analysis, Fiat FIRE 1108 engine was used. Comparison of the basic engine parameters, obtained from the simulations with actual engine performance, indicates a fairly good agreement, and thus possibility of applying of this approach in a simplified simulation of spark-ignition engines.
