Abstract

A combustion-gas recirculation system has a mixing chamber with a mixing-chamber inlet and a mixing-chamber outlet. The combustion-gas recirculation system may further include a duct connected to the mixing-chamber inlet. Additionally, the combustion-gas recirculation system may include an open inlet channel with a solid outer wall. The open inlet channel may extend into the mixing chamber such that an end of the open inlet channel is disposed between the mixing-chamber inlet and the mixing-chamber outlet. Furthermore, air within the open inlet channel may be at a pressure near or below atmospheric pressure.

Exhaust gas recirculation system for an internal combustion engine

Patent Wu, Ko-Jen

An exhaust gas recirculation system for an internal combustion engine comprises an exhaust driven turbocharger having a low pressure turbine outlet in fluid communication with an exhaust gas conduit. The turbocharger also includes a low pressure compressor intake and a high pressure compressor outlet in communication with an intake air conduit. An exhaust gas recirculation conduit fluidly communicates with the exhaust gas conduit to divert a portion of exhaust gas to a low pressure exhaust gas recirculation branch extending between the exhaust gas recirculation conduit and an engine intake system for delivery of exhaust gas thereto. A high pressure exhaustmore » « less

Dedicated exhaust gas recirculation control systems and methods

Patent Sczomak, David P.; Narayanaswamy, Kushal; Keating, Edward J.

An engine control system of a vehicle includes a fuel control module that controls fuel injection of a first cylinder of an engine based on a first target air/fuel ratio that is fuel lean relative to a stoichiometric air/fuel ratio and that controls fuel injection of a second cylinder of the engine based on a second target air/fuel ratio that is fuel rich relative to stoichiometry. The first cylinder outputs exhaust to a first three way catalyst (TWC), and the second cylinder outputs exhaust to an exhaust gas recirculation (EGR) valve. An EGR control module controls opening of the EGRmore » « less

System and method of exhaust gas recirculation

Patent Zurlo, James Richard; Neuman, Kenneth Edward; Konkle, Kevin Paul; ...

A system includes an exhaust gas an exhaust gas recirculation (EGR) mixer which includes a housing and a first passage in the housing. The first passage may be configured to supply an EGR flow into the housing. The system further includes a second passage in the housing, such that the second passage is disposed about the first passage. The second passage is configured to supply at least one fluid flow into the housing. The system also includes a region downstream from the first and second passages, and a fluid outlet downstream from the region.
