20110197569 | ON-VEHICLE NITROGEN OXIDE AFTERTREATMENT SYSTEM - An emissions system for reducing nitrogen oxides in engine exhaust includes an emissions catalyst having an inlet adapted to receive an exhaust from the engine. A fuel tank is adapted to provide fuel for combustion within the engine. A first injector is operable to inject fuel into the exhaust upstream of the catalyst. A second injector is operable to inject supplemental reductant from a supplemental reductant tank into the exhaust upstream of the catalyst. A controller is operable to control the first and second injectors and vary the supply of fuel and supplemental reductant into the exhaust to reduce nitrogen oxides within the exhaust. | 08-18-2011 |
20110203261 | Snapper Valve for Hot End Systems with Burners - A system for controlling the temperature of an exhaust stream includes a main exhaust passageway adapted to receive the exhaust stream from an engine. A bypass passage includes an inlet and an outlet in communication with the main exhaust passageway. The outlet is located downstream from the inlet. A burner is positioned within the bypass passage for treating the exhaust passing through the bypass passage. A valve is positioned within the main exhaust passageway downstream from the inlet and upstream from the outlet. The valve is operable to vary the exhaust flow through the burner. A controller selectively operates the burner to maintain a desired exhaust temperature downstream of the outlet. | 08-25-2011 |
20110283685 | Exhaust Treatment System With Hydrocarbon Lean NOx Catalyst - A system for treating an exhaust stream from an engine includes a main exhaust passageway adapted to receive the exhaust stream from the engine. A side branch is in communication with the main exhaust passageway. A regeneration unit is positioned within the side branch for combusting a fuel and heating the exhaust flowing through the main exhaust passageway. A lean NO | 11-24-2011 |
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 |
