An air intake system has two resonance chambers (3, 4) coupled to one another by means of connecting pipes (5, 6), which chambers are connected by individual intake pipes (10, 11) to the cylinders. A vessel (20) is coupled by means of resonance pipes (12-17) to the resonance chambers. A connecting pipe and several of the resonance pipes have controllable shut-off elements (30-33). A branch feeding air to the system is connected to one of the connecting pipes and to the vessel. For purposely increasing the mean pressure, the shut-off elements can be opened like a cascade as the engine speed increases, thereby increasing the volume connected at any one time. <IMAGE> |
