ABSTRACT:
An air intake system has two resonance chambers coupled together by connecting pipes. The resonance chambers are connected to the cylinders by individual intake pipes. A further common chamber is coupled by means of resonance pipes to the resonance chamber. The connecting pipe and several of the resonance pipes have controllable blocking elements. A branch that supplies air to the system is connected with one of the connecting pipes and the further chamber. To deliberately increase the mean pressure, the blocking elements can be connected in cascade fashion as the rpm rises, causing the coupled volume to increase.
