  • Patent number: 9938885
    Abstract: An engine assembly includes a turbocharger and a fluid conduit. The fluid conduit is thermally coupled to the turbocharger such that the coolant flowing through the fluid conduit can extract heat from the turbocharger. The engine assembly includes a surge tank and an engine head defining a coolant gallery. Further, the engine assembly includes an exhaust manifold integrated with the engine head. The coolant gallery is thermally coupled to the exhaust manifold such that the coolant can extract heat from the exhaust manifold. The engine assembly further includes a coolant manifold in fluid communication with the fluid conduit and the coolant gallery. The coolant manifold defines a venting orifice in fluid communication with the surge tank. Further, the coolant manifold defines a joint passageway in fluid communication with the fluid conduit. Moreover, the coolant manifold defines an interconnection passageway fluidly interconnecting the joint passageway and the coolant gallery.

  • Publication number: 20160222844
    Abstract: An engine assembly can heat or cool oil and includes an oil pan. The oil pan includes an oil pan body, and the oil pan body includes an inner pan surface and an outer pan surface opposite the inner pan surface. The inner pan surface defines a cavity configured to collect oil. The oil pan further includes a pan passageway extending through the oil pan body. The pan passageway is disposed between the inner pan surface and the outer pan surface. In addition, the pan passageway is configured to carry a heat transfer fluid in order to transfer heat between the oil disposed in the cavity of the oil pan and the heat transfer fluid.

  • Patent number: 9003792
    Abstract: In an exemplary embodiment, an internal combustion engine includes an oxidation catalyst configured to receive an exhaust gas flow from the internal combustion engine, a urea injector positioned downstream of the oxidation catalyst to inject a urea flow into the exhaust gas flow and a mixer positioned downstream of the urea injector to mix the exhaust gas flow and the urea flow to form a mixed exhaust gas and urea flow. The engine also includes a particulate filter and catalytic reduction assembly positioned downstream of the mixer to receive the mixed exhaust and urea flow from the mixer to form a treated exhaust gas flow and an exhaust gas recirculation system coupled to the particulate filter to receive a portion of the treated exhaust gas flow and recirculate the portion of the exhaust gas flow to be mixed with a fresh air flow for the internal combustion engine.

  • Publication number: 20120285144
    Abstract: In one exemplary embodiment of the invention an exhaust after treatment system is provided that includes an inlet housing, an inlet in the inlet housing configured to receive an exhaust gas flow from an internal combustion engine and an outlet in the inlet housing configured to direct the exhaust gas flow to a pollutant reduction device. The system also includes a deflector coupled to an inner surface of the inlet housing, the deflector configured to receive the exhaust gas flow from the inlet and uniformly direct the exhaust flow through the outlet and to the pollutant reduction device.
