20080271442 | Exhaust Gas System for an Internal Combustion Engine - An exhaust gas system for an internal combustion engine, comprising an oxidation catalytic converter disposed in a first exhaust gas manifold section with which the exhaust gas outlets of a first portion of the cylinders communicate, and a hydrolysis catalytic converter disposed in a second exhaust gas manifold section with which the exhaust gas outlets of the remaining portion of the cylinders communicate. The hydrolysis catalytic converter, together with the oxidation catalytic converter that annularly surrounds it, are installed in a common housing. A tubular portion of the second exhaust gas manifold section extends into the housing and accommodates the hydrolysis catalytic converter in its end portion. A tubular portion of a first exhaust gas manifold section surrounds the tubular portion of the second exhaust gas manifold section, resulting in an annular in-flow chamber for the oxidation catalytic converter that simultaneously serves as a heating chamber. A reduction agent, from which ammonia can be produced by the hydrolysis catalytic converter, can be introduced by a nozzle into the tubular portion of the second exhaust gas manifold section upstream of the hydrolysis converter. | 11-06-2008 |

20110138789 | CAPTURE OF VOLATILIZED VANADIUM AND TUNGSTEN COMPOUNDS IN A SELECTIVE CATALYTIC REDUCTION SYSTEM - An apparatus and method for treating diesel exhaust gases are described. The system consists of two functionalities, the first being a selective catalytic reduction (SCR) catalyst system and the second being a capture material for capturing catalyst components that have appreciable volatility under extreme exposure conditions. The SCR catalyst component is typically based on a majority phase of titania, with added minority-phase catalyst components comprising of one or more of the oxides of vanadium, silicon, tungsten, molybdenum, iron, cerium, phosphorous, copper and/or manganese vanadia. The capture material typically comprises a majority phase of high surface area oxides such as silica-stabilized titania, alumina, or stabilized alumina, for example, wherein the capture material maintains a low total fractional monolayer coverage of minority phase oxides for the duration of the extreme exposure. The method involves treatment of hot exhaust streams by both the catalyst material and capture material, wherein the capture material can be in a mixture with the catalyst material, or can be located downstream thereof, or both, but still be maintained at the extreme temperatures. Volatile catalyst components such as vanadia are thus removed from the vapor phase of the exhaust gas. | 06-16-2011 |
20110146253 | EXHAUST SYSTEM HAVING AN AFTERTREATMENT MODULE - 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. | 06-23-2011 |

20160121387 | PROCESSES OF MAKING EXHAUST FLANGES AND USE OF THE FLANGES THEREOF - A flange making process, includes synchronized press to process the hot sheet metal right coming out of hot rolling mill. The hot rolling mill could have impression forms for pressing flange forms on hot metal sheet. This process could eliminate the consume of steel and energy. The flange could have a protrusion around the central hole. With this protrusion, it can move weld away from sealing surface and decrease deforming and leakage of the interface. The flange could be used on a flange assembly, wherein one of the pipe is extended to another pipe. It can improve the sealing the joint of the flange assembly. | 05-05-2016 |
