1. A system configured to supply a mixture of air and exhaust gas to a compressor wheel of a compressor, the system comprising:
a main channel that is configured to debouch into an area where the compressor wheel is located at an outlet end thereof, to receive a supply of air in a first section thereof, and to receive a supply of exhaust gas in a second section thereof that is closer to the outlet end than the first section, and
an exhaust gas supply arrangement that is connected to the main channel at the position of the second section,
wherein the exhaust gas supply arrangement 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 connected 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 the outlet end thereof without first mixing with an exhaust gas flow of any other exhaust gas supply channel during operation of the system.
