Suction system for an internal-combustion engine

A suction system for an internal combustion engine, comprising:

• a resonance space defined by a resonance container arranged in a gas flow path of said suction system, connected with feed pipes for connection to intake ports for said engine;
• a hole structure comprising a plurality of holes arranged in a wall of said resonance container in an area of said resonance space;
• and
• a cover which is connected at a periphery thereof to an exterior of said wall, at a locus surrounding said hole structure, forming a reflection chamber that is coupled in fluid communication with said interior space via said hole structure.

A suction system for an internal combustion engine, comprising:

• at least one resonance container which defines a resonance space therein;
• a plurality of feed pipes connected to said resonance space, for conducting flow of air from said resonance space to intake ports of a cylinder head of the internal combustion engine;
• and
• at least one reflection chamber which adjoins a wall section of said at least one resonance container and is connected to said resonance space by way of a hole structure;
• wherein,
• said hole structure comprises a plurality of openings that are provided in said wall section of said at least one resonance container;
• and
• the reflection chamber is defined by a cover that is fastened to an exterior side of said wall section and closes off said openings.
