Japanese Patent JP2017082754

A

PROBLEM TO BE SOLVED: To curb aggravation of noise while achieving a compact arrangement of an intake passage.SOLUTION: An intake passage 20 has: a bypass passage 60 which communicates a portion at an upstream side of a compressor 52 with the portion at a downstream side thereof; a bypass passage opening-closing valve 62 which opens and closes the bypass passage 60; a first passage 122 which is extended in a first direction from the compressor 52 toward the upstream side thereof; a bent section 124 which is bent from an upstream edge of the first passage 122 to a second direction; and a second passage 126a which is extended in the second direction from the upstream edge of the bent section 124. The second passage 126a has a rectangular cross-section with a vertical dimension is longer than a horizontal dimension. A vibration control section 140 to control vibration of the second passage 126a is installed on at least either the second passage 126a or the bent section 124.SELECTED DRAWING: Figure 6
