摘要：Arrangement in an internal combustion engine, said arrangement comprises a fan for supplying combustion air to a carburetor. The fan comprises a fan housing (11) and a fan wheel (12) provided with a number of wings (13) extending in substantially radial direction from the axle (15) of rotation for the fan wheel (12). The arrangement further comprises an air inlet (14) for combustion air to the carburetor arranged at the outer edge of the wings (13) on the fan wheel (12). The outer edge of the wings (13) is arranged in a direction substantially parallel to the axle (15) of rotation for the fan wheel 10 (12). The side of the air inlet (14) closest to the outer edge of the wings (13) on the fan wheel (12) is arranged at an angle of 10° to 60° in relation to the outer edge of the wings (13) on the fan wheel (12) to reduce the amount of sound generated.
