Turbocharger for a combustion engine with magnets arranged along an air inlet channel

A turbo charger (3) driven by exhaust gas from a combustion engine (i) via an exhaust inlet (35) of the turbo charger (3), said turbo charger (3) comprising:

• an axial inlet (31) for receiving combustion air generally at atmospheric pressure;
• a bent pipe portion (37) having i) an inlet (36) that receives the combustion air generally at atmospheric pressure and ii) an outlet (34) connected to the axial inlet (31) so that the axial inlet (31) receives the combustion air generally at atmospheric pressure from the outlet (34) of the bent pipe portion (37), the bent pipe portion (37) being bent such that the combustion air runs through the bent pipe portion (37) with a first radius of curvature;
• an air inlet (5) providing an arched inlet channel (4) having i) an inlet part that receives the combustion air generally at atmospheric pressure and ii) an outlet part connected to the inlet (36) of the bent pipe portion (37),
• said inlet channel (4) being arched such that the combustion air runs through the inlet channel (4) with a second radius of curvature,
• said inlet channel (4) having, in a longitudinal flow direction between the inlet part and the outlet part, an arched wall (41), the arched wall (41) having an inner surface (43) and an outer surface (45) relative to said inlet channel (4), the outer surface (45) being concave when viewed from a centerpoint of the second radius of curvature of said inlet channel (4), the arched wall (41) having a width defining a width of the inlet channel (4) and a length in the longitudinal flow direction;
• and
• three magnets (6) arranged on said outer surface (45) of a portion of a short inner path of said arched wall (41) along the longitudinal flow direction of the inlet channel (4), the portion of the short inner path on which said three magnets (6) are arranged being concave when viewed from the center point of the radius of curvature of said outer surface (45) in the longitudinal flow direction between a first of the three magnets and a last of the three magnets, the portion of the short inner path being at an area of increased air flow, the three magnets (6) arranged having sequentially opposite magnetization directions directed mainly orthogonal to said arched wall (41), wherein a mutual separation between each of said magnets, along the longitudinal flow direction of the inlet channel (4), is at least as long as a half of a first width of a cross-section of said inlet (4).
