20120090304 | Multiple Flow Path Exhaust Treatment System - A vehicle exhaust system for an engine having a plurality of combustion chambers includes a first emission treatment device, a second emission treatment device and a housing defining a first exhaust passageway in fluid communication with the combustion chambers and containing the first emission treatment device. A second parallel exhaust passageway is in fluid communication with the combustion chambers and contains the second emission treatment device. The first and second passageways share a common wall having a serpentine shape such that the cross-sectional area of the passageways varies along a direction of exhaust flow. The first emission treatment device is positioned at a location of increased cross-sectional area in the first passageway and the second emission treatment device is positioned at an axially offset location of increased cross-sectional area in the second passageway. | 04-19-2012 |
20120102931 | HIGH VOLUME EXHAUST GAS TREATMENT SYSTEM - An exhaust system for an engine having a plurality of combustion chambers includes a housing containing a first array of parallel positioned emission treatment devices and a second array of parallel positioned emission treatment devices axially spaced apart from one another. A first exhaust passageway is in fluid communication with the combustion chambers and contains the first array of emission treatment devices. A second and separate exhaust passageway is in fluid communication with the combustion chambers and contains the second array of emission treatment devices. A first valve restricts the exhaust flow through the first exhaust passageway. A second valve restricts the exhaust flow through the second exhaust passageway. | 05-03-2012 |
20130061579 | Exhaust Gas Aftertreatment System For Engines Equipped With Exhaust Gas Recirculation - A system for treating exhaust of an internal combustion engine having an exhaust recirculation system and a turbocharger includes an exhaust passageway adapted to receive exhaust from the engine. A heat exchanger is adapted to be positioned within the exhaust gas recirculation system. A pressurized air supply system includes a conduit containing pressurized air and extending within the heat exchanger. A regeneration unit for combusting a fuel and heating the exhaust flowing through the exhaust passageway is supplied air from the air supply system that has been heated by the heat exchanger. An exhaust treatment device is positioned downstream from the regeneration unit in receipt of the heated exhaust. | 03-14-2013 |

20140116032 | Injector with Capillary Aerosol Generator - An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a coil of wire positioned proximate the valve member such that the valve member moves between a seated position and an unseated position relative to an orifice in response to energizing the electromagnet. A capillary tube is provided to convert liquid reagent to an ambient pressure vapor and supply it to the orifice. | 05-01-2014 |
