Abstract: An intake structure for an internal combustion engine of a vehicle includes a cover member covering a space defined between a front side of a radiator provided in a front part of an engine room and a vehicle body opening provided in a front end of the engine room from above, and an intake duct member resting on the cover member and having an air inlet. A part of the cover member adjoining the air inlet is formed with an opening communicating the air inlet with the space, the opening defining a larger opening area in a part thereof located on a higher temperature region side of the engine room with respect to a laterally central part of the air inlet than in a part thereof located on a lower temperature region side of the engine room with respect to the laterally central part of the air inlet.

Abstract: In an intake manifold (20) having a main pipe (21) extending in a cylinder row direction of the engine, and having an intake inlet (24) in one end part thereof; a plurality of branch pipes (22) extending from the main pipe to respective intake ports (7) of the engine, a blowby gas introduction hole (31) is provided in a part of the main pipe located between the intake inlet and a center of the main pipe with respect to the cylinder row direction, an intake pressure sensor (40) is provided in another end part of the main pipe remote from the one end part thereof.
