Abstract:
Systems and methods for fabricating bodies (e.g., porous bodies) are described. Various aspects provide for reactors and the fabrication of reactors. Some reactors include surfaces that provide for heterogeneous reactions involving a fluid (and/or components thereof). A fluid may be a gas and/or a liquid. A contaminant in the fluid (e.g., a dissolved or suspended substance) may react in a reaction. A contaminant may be filtered from a fluid. Some reactors provide for independent control of heat transfer (between the fluid, the reactor, and the environment) with respect to mass transfer (e.g., fluid flow through the reactor).
Abstract:
A configuration for a power supply of a component in an exhaust gas system includes at least one electrical contact disposed at an exhaust gas line. The at least one electrical contact is surrounded by an electrical insulation material.
Abstract:
Provided is a catalyst converter for purifying exhaust gas and a method for manufacturing the catalyst converter, in which a heater is disposed between inner/outer monoliths, to thereby heighten a heat transfer efficiency and induce a uniform catalytic reaction, and to thereby enhance a processing performance, and minimize an electric power consumption and miniaturize a device. The catalyst converter includes: a heater having a winding portion which is wound so as to have a space therein and a pair of electric power terminals; inner and outer monoliths which are inserted in the inner and outer circumferential portions of the heater winding portion wherein each of the inner and outer monoliths includes a number of hollow cells on the surfaces of which catalysts have been coated and which are formed in the lengthy direction; and a housing in which a support assembly is assembled.

Abstract:
A particle separator for the separation of particles from the exhaust gas stream of an internal combustion engine. The particle separator includes different heat transfer zones arranged at least in the main flow direction of an exhaust gas stream through the particle separator, different, that is, with respect to heat storage capacity and/or thermal conductivity and/or the heat-transfer properties from the exhaust gas stream to the particle separator. Each of these different zones makes it possible for a precisely defined amount of heat to be transferred from the exhaust gas stream to the individually assigned sections of the particle separator.
Abstract:
A substrate has corrugated sheet(s) and channel(s) for treating exhaust gases of combustion engines. The present invention also relates to methods for manufacturing and using the substrate having the open channel(s). The substrate (1) includes at least one corrugated sheet (3) having depressions (3d) and one flat wire mesh sheet (2) having depressions (2d) which is connected to the corrugated sheet (3) and between the flat wire mesh sheet (2) and the corrugated sheet (3) there are at least partially open channels (POC) for exhaust gas (EG) flow, and the depth of depression (2d) of the flat wire mesh sheet (2) is 0.05-2.0 mm smaller than the height of the corrugation (3c) of the corrugated sheet (3).
Abstract:
A method for removing soot particles from an exhaust gas of an internal combustion engine, especially of a diesel engine, includes feeding the exhaust gas through a collecting element through which the exhaust gas can pass freely but which is provided with a plurality of deflections and/or zones of swirl and calming or stabilization. At least a proportion of the particles are held or swirled around in the collecting element until there is a sufficient probability of reaction with nitrogen dioxide and a majority of the collected particles have been removed. A collecting element has flow channels through which the exhaust gas can pass freely. However, the flow channels are configured in such a way as to form deflections or zones of swirl and calming or stabilization. A system having the collecting element is also provided.
Abstract:
A bypass flow filter includes a plurality of channels which are formed of at least one structured wall layer and a filter layer. Projecting guide vanes and passages, which are formed by the wall layer and lead to a different channel, are provided in at least a majority of the channels. The passages have a narrowing cross section and a narrowing part of the cross section is directed towards an adjacent guide vane. An exhaust system and a vehicle having a bypass flow filter, are also provided.
Abstract:
The object of the invention is a porous sheet(s) for treating exhaust gases of combustion engines in open channels. According to the invention at least part of the porous sheet has a covering support having pores over 10 nm and coarse particles over 1.4 μm.
Abstract:
An aftertreatment module for use with an engine is disclosed. The aftertreatment module may have a plurality of inlets configured to direct exhaust in a first flow direction into the aftertreatment module. The aftertreatment module may also have a mixing duct configured to receive exhaust from the plurality of inlets, and a branching passage in fluid communication with the mixing duct. The branching passage may be configured to redirect exhaust from the mixing duct into separate flows that exit the aftertreatment module in a second flow direction opposite the first flow direction.
