Abstract

The melter furnace includes a heating chamber (16), a pump chamber (18), a degassing chamber (20), and a filter chamber (22). The pump chamber (18) is located adjacent the heating chamber (16) and houses a molten metal pump (30). The degassing chamber (20) is located adjacent and in fluid communication with the pump chamber (18), and houses a degassing mechanism (36). The filter chamber (22) is located adjacent and in fluid communication with the degassing chamber (20). The filter chamber (22) includes a molten metal filter (38). The melter furnace (12) is used to supply molten metal to an externally located holder furnace (14), which then recirculates molten metal back to the melter furnace (12).

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.
