  • EGR device having diffusing device and EGR mixer for EGR device
    Patent number: 9541034
    Abstract: A housing has an housing body. An inner pipe is accommodated in the housing body. The inner pipe defines an inner passage internally. The inner pipe defines an annular passage externally with the housing body. The inner pipe has through holes 68 communicating the inner passage with the annular passage. The housing internally defines an EGR channel communicating with the annular passage. The EGR channel accommodates a diffusing device 60 partitioning the EGR channel.
