<P>PROBLEM TO BE SOLVED: To provide an intake manifold capable of increasing a mixing efficiency of EGR gas with intake air when a supply amount of air to an intake port is small, and reducing a pressure loss of air when the supply amount of air to the intake port is large. <P>SOLUTION: An intake manifold has an intake passage 3 for supplying air to an intake port of an internal combustion engine. The manifold includes: an EGR inlet 8 for introducing an exhaust recirculation gas into the middle of the intake passage 3; a guide member 11 capable of guiding the exhaust recirculation gas introduced from the EGR inlet 8 toward the center of the intake passage 3; and a moving mechanism 12 that moves the guide member 11 toward the center of the intake passage 3 when a supply amount of air to the intake port is small, and moves the guide member 11 to a side away from the center side of the intake passage 3 when the supply amount of air is large. <P>COPYRIGHT: (C)2013,JPO&INPIT |
