    摘要: An exhaust treatment system for an internal combustion engine having improved mixing of an injected fluid comprises an exhaust gas conduit configured to receive exhaust gas from an internal combustion engine and to deliver the exhaust gas to the exhaust treatment system. A fluid injector in fluid communication with the exhaust gas conduit configured delivers a fluid into the exhaust gas and an evaporation volume disposed in the exhaust conduit downstream of the fluid injector is configured to slow the bulk velocity of the fluid and exhaust gas mixture to thereby increase the residence time of the exhaust gas mixture therein. An exhaust treatment device is configured to receive the fluid and exhaust gas mixture.

    摘要: A mixing plenum for exhaust gas comprises a canister with an inlet and an outlet. A bulkhead is located downstream from the inlet to define an exhaust gas consolidation chamber. An opening in the bulkhead allows exhaust gas to enter a u-shape conduit configured to direct the exhaust gas from a downstream direction to an upstream direction before releasing the exhaust gas back into the plenum downstream of the bulkhead. An injector is configured to inject fluid into the exhaust gas entering the conduit. A conduit exit located a distance “E” from the downstream side of the bulkhead allows the exhaust gas/fluid mixture to exit the conduit into a larger exit volume of the compact mixing can, in the manner of an expansion chamber, where its velocity slows and further mixing of the fluid/exhaust gas occurs and exits the compact mixing can through the outlet flange.

    摘要: An exhaust treatment system for an internal combustion engine comprises an exhaust gas conduit configured to receive an exhaust gas from the internal combustion engine and to deliver the exhaust gas to an exhaust treatment device. A fluid delivery system is located upstream of the exhaust treatment device and is configured to deliver a fluid thereto. It comprises a fluid injector, a fluid tube in fluid communication with the fluid injector and extending radially into the exhaust gas conduit for receipt of fluid from a spray tip of the fluid injector, a controller configured to energize the fluid injector to deliver fluid to the fluid tube, and opening(s) in the tube, disposed beyond the boundary layer of exhaust gas flow in the exhaust gas conduit, for release of the fluid into the exhaust gas flow.
