A suction system has an arrangement for utilizing resonance effects and is suitable for an internal-combustion engine having opposed cylinder banks. The suction system has a resonance container which has boundary walls. On the one hand, the resonance container is connected with the atmosphere and, on the other hand, it is connected with cylinders of the internal-combustion engine, the arrangement being provided in the resonance container as a control device which can vary the resonance cross-section, and the resonance container is connected with a feeding device having separate feeding pipes. For optimizing the torque behavior of the internal-combustion engine, the control device is fixed from the idling to a medium rotational speed range in a first end position and, together with the feeding pipes of the feeding device, forms two guiding channels which supply the cylinders the two cylinder banks with air.

Suction system

A suction system for an internal-combustion engine has an arrangement for utilizing resonance effects. The arrangement includes a control device which is arranged inside the resonance container and by way of which the resonance cross-section can be varied as a function of parameters of the internal-combustion engine.
