Abstract
An exhaust gas recirculation system for an engine includes a conduit, and a mixer. The conduit is configured to direct to direct exhaust gas away from an exhaust manifold. The mixer is configured to direct exhaust gas from the conduit, into an engine air intake system. The mixer is arranged with an exhaust gas mixing volute chamber having a plurality of mixing vanes configured to direct the exhaust gas into a central intake airflow upstream of an intake manifold.
Claims11
A vehicle comprising:
- an internal combustion engine having at least one cylinder;
- an air intake system configured to deliver air to the at least one cylinder;
- and
- an exhaust system having;
- a set of conduits configured to direct an exhaust gas away from the at least one cylinder, and
- an exhaust gas recirculation system having,
- at least one tube configured to direct the exhaust gas away from the set of conduits, and
- a mixer configured to direct the exhaust gas from the at least one tube into the air intake system, wherein the mixer forms an annular ring having a continuous volute chamber exhaust gas opening disposed radially around an inner diameter of the annular ring and attached to an intake tube, the annular ring is a portion of the air intake system that is configured downstream of a throttle valve and upstream of an intake manifold, the throttle valve includes at least one of a single twist throttle plate or a double twist throttle plate, the mixer includes at least one vane extending across the volute chamber opening and into a flow path of at least one of the exhaust gas and the air intake system, and the at least one vane has an outer surface and is configured to blend the exhaust gas and the air flowing over the outer surface and prior to introduction into the internal combustion engine.
5 more elements
An engine exhaust gas mixer comprising:
- a housing forming an annular ring that defines a central opening extending radially around an inner diameter of the annular ring, the housing further defining,
- an exhaust gas inlet,
- an air intake including a twist throttle plate, the twist throttle plate having at least one curved end, the curved end directing an intake air in a non-laminar flow path, and
- at least one mixing vane configured between the exhaust gas inlet and the annular ring, the at least one mixing vane extending across the central opening and including at least one of a twist or slope to swirl an exhaust gas of the engine as the exhaust gas flows over an outer surface of the at least one mixing vane.
