<P>PROBLEM TO BE SOLVED: To make the recirculated gas amount of an exhaust gas constant regardless of the cylinder that has emitted the exhaust gas. <P>SOLUTION: The exhaust gas recirculation device 20 comprises an exhaust gas recirculation pipe 21 disposed between an intake manifold having a plurality of intake branch pipes to be each interlocked with an intake port of each cylinder, and an exhaust manifold 40 having a plurality of exhaust branch pipes 41-43 to be each interlocked with an exhaust port of each cylinder so that a part of the exhaust gas discharged to each of the exhaust branch pipes 41-43 from the exhaust port of each of the cylinders is introduced into the exhaust gas recirculation pipe 21 for recirculation to the intake manifold. The device has a communication pipe part 30 for guiding a part of the exhaust gas from the exhaust branch pipes 41-43 to the exhaust gas recirculation pipe 21 with the exhaust gas recirculation pipe 21 and the exhaust branch pipes 41-43 in a communicated state. In the communication pipe part 30, the respective distances of the exhaust gas channels from the positions connected with the exhaust branch pipes 41-43 to the positions connected with the exhaust gas recirculation pipe 21 are equivalent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
