International Classification:

F01N 1/00

US Classification:

60324, 60274, 60286, 60287, 60301, 60305

Abstract:

A system and method for treating exhaust gasses from an engine is described. In one example, the exhaust gasses are routed from the engine to atmosphere through a helical exhaust passage. The helical exhaust passage includes a plurality of spatially separated exhaust passages that separates the exhaust flow into separated smaller flows, wherein the smaller flows are re-introduced into a common passage and re-combined to form a single exhaust flow, and wherein the plurality of spatially separated exhaust passages induces a helical flow pattern within the re-combined exhaust flow.

International Classification:

F01N 3/10

US Classification:

60303, 60324

Abstract:

An exhaust system for an internal combustion engine for a vehicle is provided. The system comprises an exhaust passage for transporting exhaust gases from the engine; an injector coupled to a wall of the exhaust passage, said injector including an injection axis that is angled relative to a longitudinal axis of a mixing region of the exhaust passage; and a first mixing device arranged within the exhaust passage downstream of the injector within the mixing region, said first mixing device including a plurality of flaps, wherein said plurality of flaps are inclined relative to the longitudinal axis; a second mixing device arranged within the exhaust passage downstream of the first mixing device; wherein the injection axis of the injector intersects the first mixing device.

International Classification:

F01N 3/10

US Classification:

60295

Abstract:

A diffuser for aiding in the vaporization and mixing of an injected reactant with the exhaust gas feed stream of an exhaust gas aftertreatment system is disclosed. The diffuser is disposed within an exhaust gas conduit of the exhaust gas aftertreatment system and has an impingement surface and a baffle plate disposed downstream of and adjacent thereto. The baffle plate extends outwardly from the diffuser, to terminate at a baffle plate tip that is located intermediate of the diffuser and an inner wall of the exhaust gas conduit. The baffle plate is operable to trap a portion of an exhaust gas feed stream, and a reactant resident therein, to increase the vaporization and residence time of the reactant in the exhaust gas feed stream.

International Classification:

F02B 47/08
F02M 25/07

US Classification:

12356816

Abstract:

An internal combustion engine is equipped with an EGR system that includes an EGR heat exchanger. A method for monitoring the EGR heat exchanger includes monitoring an EGR gas inlet temperature to the EGR heat exchanger, an EGR gas outlet temperature from the EGR heat exchanger, a coolant temperature and a mass EGR flowrate through the EGR heat exchanger for a present engine operating point. An actual thermal effectiveness of the EGR heat exchanger for the present engine operating point is determined. A maximum heat transfer coefficient for the EGR side of the EGR heat exchanger is determined for the present engine operating point. The EGR heat exchanger is regenerated when the actual heat transfer coefficient differs from the maximum heat transfer coefficient for the present engine operating point.

Appl. No.:

13/926036

Inventors:

PATRICK G. SZYMKOWICZ - SHELBY TOWNSHIP MI, US
SANDRO R. BALESTRINO - PLYMOUTH MI, US

International Classification:

F02M 25/07

US Classification:

60273, 60278

Abstract:

An apparatus for mitigating fouling within a heat exchanger device includes an internal combustion engine fluidly coupled to an intake manifold upstream of the engine and an exhaust gas manifold downstream of the engine. The apparatus further includes an external exhaust gas recirculation circuit fluidly coupled to the exhaust gas manifold at a first end and configured to selectively route exhaust gas flow into the intake manifold at a second end. The exhaust gas recirculation circuit includes the heat exchanger device for cooling the EGR flow prior to entering the intake manifold, and a deposit filter fluidly coupled upstream of the heat exchanger device and configured to trap combustion by-products within the EGR flow.

International Classification:

F01N 3/08

US Classification:

60274, 60282

Abstract:

An apparatus for mitigating fouling within a heat exchanger device includes an internal combustion engine and an external exhaust gas recirculation (EGR) circuit. The internal combustion engine is fluidly coupled to an intake gas manifold upstream of the engine and an exhaust gas manifold downstream of the engine. The EGR circuit is fluidly coupled to the exhaust gas manifold at a first end and is configured to selectively route back exhaust gas flow as EGR flow into the intake gas manifold at a second end. The EGR circuit includes the heat exchanger device for cooling the EGR flow prior to entering the intake manifold and a surface deposit removing device configured to remove surface deposit build-up from within the heat exchanger device when the surface deposit removing device is activated.
