摘要： A method for monitoring a hydrocarbon-selective catalytic reactor device of an exhaust aftertreatment system of an internal combustion engine operating lean of stoichiometry includes injecting a reductant into an exhaust gas feedstream upstream of the hydrocarbon-selective catalytic reactor device at a predetermined mass flowrate of the reductant, and determining a space velocity associated with a predetermined forward portion of the hydrocarbon-selective catalytic reactor device. When the space velocity exceeds a predetermined threshold space velocity, a temperature differential across the predetermined forward portion of the hydrocarbon-selective catalytic reactor device is determined, and a threshold temperature as a function of the space velocity and the mass flowrate of the reductant is determined. If the temperature differential across the predetermined forward portion of the hydrocarbon-selective catalytic reactor device is below the threshold temperature, operation of the engine is controlled to regenerate the hydrocarbon-selective catalytic reactor device.

摘要： A diesel exhaust aftertreatment device regeneration system includes an exhaust conduit adapted to conduct exhaust gas to an exhaust gas aftertreatment device. The system further includes a low pressure bottom feed fuel injector having an inlet portion fully received within a chamber of an adaptor housing having a lower portion attached to the exhaust conduit. The housing is provided with fuel flow openings to allow low pressure fuel to circulate around and cool the fuel injector inlet portion within the chamber. Fuel injected into the exhaust conduit is preferably targeted toward a vaporization member, within the exhaust conduit, operative to absorb heat from the exhaust gas and vaporize fuel deposited thereon. A plurality of inwardly extending mixing baffles within the exhaust conduit intermediate the vaporization member and the aftertreatment device extend the mixing path to improve fuel vaporization for assisting regeneration of the device.

摘要： A thin layer of low mean-pore-size filter material that permanently accommodates the accumulation of exhaust particulates (as soot or a soot cake) is carried on a porous ceramic support. The supported filter material is closely coupled with the exhaust manifold of the engine, for the purpose of passive regeneration of stored particulates, and removes particulate matter from the exhaust which is directed through the filter layer and ceramic support. The oxygen content of the exhaust oxidizes the particulate matter on the filter material. In a preferred embodiment, a thin layer of the filter material is supported on inlet channel walls of a wall flow-through ceramic filter body to remove the particles from the exhaust. The filter body comprises an upstream exhaust gas flow inlet face with openings to a plurality of inlet channels and a downstream face with a like plurality of openings from outlet channels. The inlet channels are closed at the downstream face and the outlet channels are closed at the inlet face. So the exhaust stream enters the inlet channels and flows through the filter layers and supporting channel walls to an outlet channel. The filtered exhaust stream exits the outlet end of the filter body and is combined into an exhaust passage downstream of the filter body for further treatment as may be necessary.

摘要： Where oxygenated hydrocarbons, such as ethanol, may be considered for use as a reductant to be added to diesel or gasoline engine exhaust for promoting the catalyzed reduction of NOx to N2, there is a need to continually adjust the amount of the reductant to be added as engine and catalyst operating conditions change. It is found that useful methods, to be practiced using a suitably programmed on-vehicle computer, can be based on a correlation for ethanol, or other specific reductant, with continually measured values of catalyst temperature, the oxygen and NOx contents of the exhaust, and the volumetric flow rate of the exhaust over a reduction catalyst, such as silver supported on alumina, selected for reduction of NOx to nitrogen. Effective amounts of the reductant for substantial reduction of NOx may be reliably determined using at least such parameters.
摘要翻译：当氧化烃如乙醇被认为可用作还原剂加入到柴油或汽油发动机废气中以促进NOx催化还原成N2时，需要不断调整还原剂的量随着发动机和催化剂的运行条件的变化。发现使用适当编程的车载计算机实施的有用方法可以基于乙醇或其它特定还原剂的相关性，其中连续测量催化剂温度值，排气的氧气和NOx含量，以及选择用于还原NOx至氮的还原催化剂（例如负载在氧化铝上的银）的排气的体积流量。可以使用至少这样的参数可靠地确定用于大量还原NOx的还原剂的有效量。
