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 |

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 |
