The guide structure for a fluid flow in motors, to take the air intake or a mixture of air/fuel, has an inner wall with a surface structure with a structure depth of 0.025-0.1 mm. The gap (s) between the longitudinal legs of the U-profile is 1.2/*h to 4.0/*h, measured from the center, where h is the leg height. |
