<p><P>PROBLEM TO BE SOLVED: To improve EGR distributivity to each cylinder by uniformly mixing much EGR, and to supply EGR to each cylinder after sufficiently decreasing high EGR temperature. <P>SOLUTION: This exhaust reflux device comprises a collector 1 communicating with an intake manifold connected with each cylinder, an intake duct 2 that is connected to an end of the collector 1, has an intake inlet on the opposite end side of the collector, and is disposed over an engine, an EGR valve 3 that is mounted to the upstream section of the intake duct 2 and introduces the EGR to the intake duct 2 via an external reflux passage 6, and a throttle chamber 4 that is located in the upstream side of the EGR valve 3 and connected with the intake duct 2. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
