Supplying a mixture of air and exhaust gas to a compressor wheel of a compressor

An exhaust gas supply arrangement configured to be used in a system that is configured to supply a mixture of air and exhaust gas to a compressor wheel of a compressor, wherein the exhaust gas supply arrangement is formed as a single-piece and comprises:

• a central inlet channel duct and at least two exhaust gas supply channel ducts attached to the central inlet channel duct which are separate from each other along at least a part of their length,
• wherein the exhaust gas supply arrangement is configured to be connected to a main channel at ends of the exhaust gas supply channels such that each of the exhaust gas supply channels debouches directly into the main channel and thereby enables direct injection of an exhaust gas flow in air flowing through the main channel without first mixing with an exhaust gas flow of any other exhaust gas supply channel during operation of the system.

A method of manufacturing a system configured to supply a mixture of air and exhaust gas to a compressor wheel of a compressor, the method comprising:

• providing a main channel and arranging the main channel to debouch into an area where the compressor wheel is located at an outlet end thereof, and
• providing an exhaust gas supply arrangement that comprises a central inlet channel duct and at least two separate exhaust gas supply channel ducts, extending from the central inlet channel, which are separate from each other along a part of their length, and connecting the exhaust gas supply arrangement to the main channel at ends of the exhaust gas supply channels, and
• wherein each of the exhaust gas supply channels debouches directly into the main channel and thereby enables direct injection of an exhaust gas flow in air flowing through the main channel towards an outlet end thereof without first mixing with an exhaust gas flow of any other exhaust gas supply channel during operation of the system.
