Abstract:
Suction system for utilizing resonance effects for an internal-combustion engine with opposed cylinder banks, said suction system comprising:a resonance container formed by a plurality of boundary walls, an interior of said resonance container being communicated with the atmosphere and being communicated with cylinders of the internal-combustion engine; anda control device arranged inside the resonance container, said control device including a plurality of guide walls extending at a distance from the boundary walls of the resonance container, said control device being movable to vary a resonance cross-section of said resonance container;wherein the resonance container has a prism-type basic shape with said boundary walls including a pair of longitudinal walls facing the cylinder banks, respectively, and a first front wall and a second front wall extending between said longitudinal walls, the guide walls of the control device extending parallel to said longitudinal walls and said front walls;wherein the guide walls are formed by two parallel leg-type walls coupled by a web-type wall, said leg-type walls and said web-type wall forming a U-shape; andwherein the control device is adjustable between a first end position and a second end position, the web-type wall of the control device, at least in the first end position, together with the first front wall, defining a connection duct to a pair of resonance chambers in the resonance container which are disposed in front of the cylinder banks, respectively.
