Title:
MIXING CONNECTOR AND ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/230994
Kind Code:
A1
Abstract:
A mixing connector (100) comprises: an intake passage (101); an EGR passage (103) that returns some of the exhaust gas discharged from an engine body to the intake passage as an EGR gas; and a merging part (104) that connects the EGR passage to the intake passage so that the longitudinal directions of the intake passage and the EGR passage intersect with each other. An upstream side region (116) of an opposite wall surface (115), which constitutes the inner surface of the intake passage and is located on the opposite side to the merging part, is located closer to an introduction port (101A) side of the intake passage than the merging part, and comprises: a first wall surface (116A) and a second wall surface (116B) which are arranged with a space therebetween and in order from the merging part side toward the introduction port; and a third wall surface (116C) that protrudes, between the first wall surface and the second wall surface, inwards with respect to the first wall surface.
