Abstract: An intake duct for an internal combustion engine includes a plastic molded first split body and a fibrous molded second split body. The first split body includes a first flange. The second split body includes a body and a second flange that protrudes from the body. The first flange and the second flange are joined to each other through welding so that the intake duct includes a tubular shape. The second flange includes a joint joined to the first flange. The joint includes a low-compression portion formed at a lower compressibility than the body of the second split body.

Abstract: An intake duct for an internal combustion engine includes a tubular wall configuring an intake passage. The wall includes segments that are separate from each other in a circumferential direction of the wall. At least one of the segments is made of a compression-molded fibrous body. Each of the segments includes a flange protruding radially outwards from the wall and having a joint. The joint of the flange of each of the segments and the joint of the flange of the corresponding one of the segments are joined to each other. Each of the flanges includes an opposing surface opposed to the corresponding one of the flanges. The opposing surface is provided with a step portion that is located closer to a proximal side of the flange than to the joint and forms a step in a thickness direction of the flange.

Abstract: An inlet duct for an internal combustion engine includes a duct member made of a compression molded fiber material. The duct member includes a main body and end portions provided on opposite sides in an axial direction of the main body. The main body includes at least one high-compression portion and at least one low-compression portion, which is made through compression molding at a compression ratio lower than that of the at least one high-compression portion. The at least one low-compression portion extends throughout a length in the axial direction of the main body.

Abstract: An intake duct for an internal combustion engine includes a plurality of segments coupled together into a tubular shape. The segments include at least a first segment and a second segment. The first segment is formed from a material harder than the second segment. The first segment includes a groove that extends in the extending direction in a portion coupled to the second segment and projections that project from one of two inner surfaces of the groove. The second segment is formed from a material that allows for elastic deformation. The second segment includes a rib. The rib extends in the extending direction and has a projection width that is less than the opening width of the groove. The rib is fitted into the groove so that the projections locally compress the rib in the width direction of the groove.

Abstract: An inlet duct includes a tubular main body formed by a compression-molded fibrous molded body. The main body includes an alternate layout region in which an air-impermeable high-compression portion and an air-permeable low-compression portion hat is compression-molded at a lower compressibility than a compressibility of the high-compression portion are alternately laid out in an axial direction of the main body. The alternate layout region is configured such that an arbitrary pair of points at an equal distance in the axial direction to a central position in an upstream region and a downstream region of the alternate layout region include only points that are both located in the low-compression portions and points one of which is located in the low-compression portion and the other one of which is located in the high-compression portion.

Abstract: An intake duct for an internal combustion engine includes a tubular side wall. The side wall includes a first split body and a second split body that are separate from each other in a peripheral direction of the side wall. The first split body includes a rib that divides an inside of the side wall into passages and extends in an extending direction of the side wall. A distal end of the rib in a protruding direction of the rib is spaced apart from an inner surface of the second split body. A portion of the second split body opposed to the distal end is provided with a breathable part that allows air to flow between the inside and an outside of the side wall.
