Abstract
A housing has an outer pipe, an inner pipe, and an EGR inlet. The inner pipe is located inside the outer pipe. The inner pipe defines an inner passage internally. The inner pipe defines an annular passage externally with the outer pipe. The EGR inlet defines an EGR channel therein to communicate with the annular passage. The inner pipe has an end surface defining a throttle passage extending circumferentially. The throttle passage communicates the annular passage with the inner passage radially inward. The throttle passage is narrow on a side of the EGR channel and is wide on an opposite side of the EGR channel.
