<P>PROBLEM TO BE SOLVED: To provide an air intake device of an internal combustion engine that uniformly distributes EGR gas to a plurality of cylinders and properly mixes intake air with the EGR gas. <P>SOLUTION: The air intake device 10 includes: branch pipes 16-19 each having a downstream end connected to one side of an engine body 1; an intake air chamber 20 connected to upstream ends of the branch pipes 16-19; and a common intake air introducing part 21 to be connected to the center in the cylinder arrangement direction of the intake air chamber. The intake air chamber 20 includes a swollen part 22 swollen larger toward the engine body 1 than the common intake air introducing part 21. An EGR introducing passage 33 is connected to the center in the cylinder arrangement direction of the swollen part 22. A downstream end 33a of the EGR introducing passage is directed to a wall surface 22a of the swollen part 22 on the side of the common intake air introducing part 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
