Simulating a full engine that includes a turbocharging system is time consuming and demands high power computing capabilities. Simplification of the engine model was considered indispensable to verify different boosting system concepts in reasonable timeframes. An attempt was made to reduce the computing time demand using the one-dimensional Ricardo WAVE software. Comparison of results of selected inlet and exhaust gas parameters of models created in 3D software (Ansys FLUENT) and Ricardo WAVE showed differences between 1 and 12%. Those discrepancies may be acceptable for initial verification of different boosting system concepts. In order to obtain more accurate results it is recommended to link the engine FLUENT model with Ricardo WAVE boosting model.
