| 20090000471 | Filter service system and method - According to an exemplary embodiment of the present disclosure, a system for removing matter from a filtering device of a work machine includes a gas pressurization assembly. An element of the gas pressurization assembly is removably attachable to a first orifice of the filtering device without removing the filtering device from a work machine to which the filtering device is connected. The system also includes a heat source fluidly connected to the gas pressurization assembly. | 01-01-2009 |
| 20090288392 | Engine system having particulate reduction device and method - An internal combustion engine system includes an engine having an engine housing. The engine system further includes an exhaust system, and a turbine disposed within the exhaust system. A particulate reduction device is disposed in the exhaust system upstream of the turbine. The particulate reduction device includes an exhaust retarder having a flow property which is based at least in part on a residence requirement for combustion of particulates in exhaust gases passing therethrough. The flow property may be a flow restriction property, and the exhaust retarder may include a flow restricting trapping element configured to trap particulates in the exhaust gases. The flow restricting trapping element defines a combustion efficacy to exhaust mass flow and temperature coefficient for the particulate reduction device which is based at least in part on a combustion initiating residence requirement for particulates passing through the particulate reduction device. | 11-26-2009 |
| 20100146948 | Exhaust system promoting decomposition of reductants into gaseous products - An engine exhaust treatment system. The treatment system includes and a reductant injector adapted to deliver a reductant composition into an exhaust stream moving along an exhaust flow path. A selective catalytic reduction device is disposed downstream from the reductant injector. The selective catalytic reduction device is adapted to reduce an amount of NOx in exhaust gases produced by an engine by reaction of the NOx with ammonia. A basic and/or amphoteric oxide contact surface is disposed along the exhaust flow path. | 06-17-2010 |

| 20100221163 | METHOD TO SEQUESTER CO2 AS MINERAL CARBONATE - A disclosed method for removing carbon dioxide from flue gases includes passing the carbon dioxide-containing through a bed of particulate material such as one or more metal silicates, alkaline earth metal oxides and combinations thereof. The carbon dioxide reacts with the particulate material to produce one or more metal carbonates and a carbon dioxide-depleted flue gas. A disclosed flue gas exhaust system includes a flue or exhaust conduit that houses a bed of particulate material so that at least some flue gas passing through the flue also passes through and makes contact with the bed. The particular material may be ground olivine or serpentine. | 09-02-2010 |

| 20090056320 | Exhaust system having catalytically active particulate filter - A catalyst is disclosed. The catalyst contains a ternary nitride and at least one of gold, osmium, iridium, palladium, rhodium, rhenium, ruthenium, or cesium. The catalyst may be used for a particulate filter in an engine exhaust treatment system. | 03-05-2009 |
| 20090194741 | Exhaust system having a carbon oxide catalyst - A catalytic filter system is disclosed. The catalytic filter system contains a catalyst including a ternary nitride and at least one of gold, osmium, iridium, palladium, rhodium, rhenium, ruthenium, or cesium. The catalytic filter system may further include an energy source situated to impart energy to the catalyst. | 08-06-2009 |
| 20100018476 | On-board hydrogen generator - A hydrogen generator for use with an engine is disclosed. The hydrogen generator has an exhaust duct situated to receive exhaust from the engine, and an SCR device located within the exhaust duct. The hydrogen generator also has a housing in fluid communication with the exhaust duct upstream of the SCR device, an electrolyte solution disposed within the housing, and a plurality of electrodes at least partially submerged in the electrolyte solution. The electrodes are electrically powered to produce hydrogen gas, and the hydrogen gas is directed to mix with the exhaust. | 01-28-2010 |
| 20100018850 | System for removing particulate matter from exhaust streams - An aspect of the present disclosure is directed to a system for removing particulate matter from an exhaust stream. The system may include an ionization device configured to ionize particles of an exhaust stream. The system may further include an electromagnetic field generating device configured to deflect the ionized particles onto an inner-surface of an exhaust passageway, the inner-surface of the exhaust passageway being coated with a substance for lowering activation energy for a reaction of the ionized particles. The system may further include a regeneration means configured to remove particles from the exhaust passageway. | 01-28-2010 |

| 20080236118 | Exhaust particulate filter for a machine engine system and assembly method therefor - An exhaust particulate filter for an engine system includes a housing having an inlet, an outlet and a shell shaped to fit the particulate filter within a predefined spatial envelope. Filter elements arranged in a bundle and having a packing arrangement are positioned within the housing. Each of the filter elements includes a perforated tube wrapped with fibrous metallic filter media. The bundle defines a perimetric line at least partially matched to the shape of the shell. An assembly method for a particulate filter includes arranging filter elements in a packing structure within a bundle, the bundle having peripherally located filter elements and internally located filter elements. The filter elements each include a perforated tube wrapped with fibrous metallic filter media. The assembly method further includes positioning the bundle of filter elements within a housing having a shape at least partially matched to a shape of the bundle. A unique method of joining various of the components via swagging is also disclosed. Clamping of the filter media, and joints between filter element and support plates, may be achieved via swagging, for example. | 10-02-2008 |
| 20090188389 | Particulate filter for an exhaust aftertreatment system of a machine and filtering method thereof - A particulate filter includes a filter element comprising a non-perforated tube having an exhaust inlet at a first end and an exhaust outlet at a second end. A fibrous metallic filter medium is disposed within the filter element and is configured to trap particulate matter from an exhaust gas. A first metallic foam disk is attached at the second end of the filter element, and retains the fibrous metallic filter medium within the filter element. A second metallic foam disk may be attached at the first end of the filter element and may allow the particulate filter to be reversed with respect to an exhaust gas flow. | 07-30-2009 |
