<p>PROBLEM TO BE SOLVED: To provide an EGR gas mixer for allowing proper disassembly and easy internal cleaning when necessary.SOLUTION: An intake pipe 1 is detachably divided in the middle so that the inner diameter of an intake pipe 1B on the downstream side is relatively larger than the inner diameter of an intake pipe 1A on the further upstream side than the divided part. On the most upstream part of the intake pipe 1B on the downstream side, a cone-shaped venturi component 10 is arranged whose diameter is gradually enlarged toward the flowing direction of intake air 2 to make a flow path of the intake pipe 1A on the upstream side continuous with a flow path of the intake pipe 1B on the downstream side in a stepless manner. An annular chamber 11 is laid on the outer periphery of the venturi component 10. To the annular chamber 11, an EGR pipe 6 is connected which guides part of exhaust gas 5 removed from the exhaust side. Slits 12 are opened in a plurality of peripheral positions of the venturi component 10.</p> |
