EXHAUST GAS RECIRCULATION DEVICES

摘要

Embodiments of an exhaust gas recirculation (EGR) mixing device include an air inlet port and an outlet port disposed at opposite ends of the mixing pipe, an exhaust feeder having a scroll mixing chamber and occupying a portion of the mixing pipe between the air inlet port and the outlet port. The exhaust feeder includes an exhaust feed splitter beam disposed within an open-ended exhaust inlet tube and the scroll mixing chamber, and can be configured to split an exhaust stream into a plurality of exhaust streams before entering the scroll mixing chamber.
