  • Suction system for an internal-combustion engine
    Patent number: 6830024
    Abstract: A suction system for an internal-combustion engine is provided with at least one container, which can be connected by way of feed pipes with the intake ports of a cylinder head. Openings of the intake ports for charge cycle control are monitored by valves. In the container or in the feed pipes, at least one reflection chamber is provided, which is connected with the interior volume of the container by way of a hole structure. The hole structure is formed by a plurality of openings that are formed in a wall section of the container, and are closed off by a cover fastened to the exterior side of the container wall, providing a reflection chamber which reduces noise in the suction system without adversely affecting air flow in the interior of the suction system.
