| 摘要 |
The present invention relates to a fresh gas system (1) for supplying an internal combustion engine (4) with fresh gas, in particular in a motor vehicle, having a charging device (8) for increasing the pressure of the fresh gas and having a swirl generator (12), which is arranged upstream of the charging device (8), for generating a swirl, which rotates about the main flow direction of the fresh gas, in the fresh gas, wherein the swirl generator (12) has guide blades (14) with adjustable angle of incidence. In order to be able to produce the fresh gas system (4) more cost-effectively, the swirl generator (12) has a flow guide body (13) on which the guide blades (14) are integrally formed and which, in order to adjust the angle of incidence of the guide blades (14), can be twisted with elastic deformation about the main flow direction starting from an undeformed initial position.
