An exhaust gas recirculation (EGR) system, comprising:
- a dual poppet valve arranged upstream of a cooler relative to a direction of EGR flow, and ribs arranged between the dual poppet valve and a plurality of tubes of the cooler.
A system, comprising:
- an exhaust gas recirculation (EGR) cooler comprising a plurality of tubes and a dual poppet valve assembly arranged therein and ribs arranged in an outlet chamber between the dual poppet valve assembly and the plurality of tubes;
- wherein
- the dual poppet valve assembly comprises a first poppet and a second poppet actuated via a cam of a camshaft, the first poppet configured to control EGR flow from a primary chamber to a first secondary chamber and the second poppet configured to control EGR flow from the primary chamber to a second secondary chamber, each of the first secondary chamber and the second secondary chamber are fluidly coupled to the outlet chamber.
An exhaust gas recirculation (EGR) system, comprising:
- a dual poppet valve assembly arranged upstream of a cooler relative to a direction of EGR flow, the dual poppet valve assembly comprising a first poppet coupled to a first shaft and a second poppet coupled to a second shaft;
- a camshaft comprising a cam arranged between the first shaft and the second shaft;
- and
- ribs arranged between a plurality of tubes of the cooler and the first poppet and the second poppet, wherein the ribs are angled relative to a direction of EGR flow into the plurality of tubes.
