Mathematical model of the system includes engine cylinders as oscillation sources, intake collector, aircleaner, suction and connective manifolds of intake system. Three-dimensional models of sound emission are used for the aircleaner. These models allow to achieve sufficient results for middle and high frequency ranges. The mathematical model allows to calculate the noise level of the intake system and to appreciate cylinder charging for different power settings. Moreover, using this model system transmission functions are determined on the basis of different parameters to appreciate the model properties as the automatic control system object in the active intake noise cancellation system while choosing the optimal regulation algorithm. The model has been realised for the simple algorithmic languages.
