Abstract
An EGR mixer comprises an upstream conduit section having a contracting flow area in a direction of air flow through the mixer, a downstream conduit section having an expanding flow area in the direction of air flow through the mixer, a slot formed in the downstream conduit section for admitting exhaust to the air flow, and an abrupt flow-expanding ridge disposed between the upstream and downstream conduit sections. With the EGR mixer configured in this manner, recirculated exhaust may be effectively homogenized into an intake air flow with reduced drag.
