20150354432 | MIXING CHAMBER - A mixing chamber for mixing an additive in an exhaust system of an internal combustion engine, having a single-part or multi-part housing which has an entry opening for exhaust gas having a flow cross-section and having a central entry axis, and which has, arranged downstream of the entry opening, an exit opening for exhaust gas having a flow cross-section and having a central exit axis. A flow-guiding element is arranged within the housing between the two openings, wherein the flow-guiding element is tubular and forms at least one channel having a channel axis, said channel having an inlet and having an outlet, via which the entire exhaust gas stream is guided, in a flow direction parallel to the channel axis, to the outlet having an outlet cross-section, and the flow direction deviates relative to the central exit axis by an angle a of between 20° and 80°. The mixing chamber is to be designed and arranged in such a way that, with a reduced overall length, an improved distribution of the mixture of exhaust gas and additive over the substrate surface is achieved and at the same time deposits of the additive are avoided. A downstream substrate is provided adjacent to the outlet in the direction of the central exit axis, the downstream substrate having a substrate cross-section that corresponds to the outlet cross-section. | 12-10-2015 |
20150152762 | EXHAUST-GAS HEAT EXCHANGER - An exhaust-gas heat exchanger for an exhaust system for cooling an exhaust-gas flow, having an inner pipe and an outer pipe, wherein the two pipes are indirectly or directly welded to one another in sealing fashion at the inlet side, a jacket pipe is arranged around the outside of the outer pipe and an annular gap for coolant is arranged between the outer pipe and the jacket pipe, and the inner pipe has an axial flow cross section (A | 06-04-2015 |
20150093298 | Apparatus for the Aftertreatment of the Exhaust Gases of Diesel Engines - An exhaust gas aftertreatment device, including a bent exhaust pipe, a mixing pipe having a closed end at the exhaust pipe bend and a bell-shaped widened portion in at least partial contact with the exhaust pipe at its opposite end, and a nozzle connected to a receptacle in the mixing pipe closed end for injecting an additive into the exhaust gases, with a mixing one in the exhaust pipe between the urea nozzle and the exhaust pipe outlet in which the exhaust gases flow around the mixing pipe symmetrically and form a double eddy in the mixing pipe. | 04-02-2015 |
20150047922 | MUFFLER HAVING COUPLING OF A TAILPIPE BY MEANS OF A COUPLING CHAMBER - A muffler for an exhaust system of an internal combustion engine having a housing wall, having a muffler housing with at least one inlet pipe guided through the housing wall and at least one outlet pipe guided through the housing wall, wherein the inlet pipe has at least one outflow opening via which the exhaust gas can flow from the inlet pipe into the outlet pipe, whereby, within the muffler housing, at least one coupling chamber with a chamber wall is provided with a centre axis, which forms a flow channel between the inlet pipe and the outlet, whereby the chamber wall encloses the inlet pipe or the outlet pipe in the receiving direction E | 02-19-2015 |
20140306446 | FITTING FOR AN EXHAUST PIPE - A fitting for the mounting of an exhaust probe on an exhaust pipe with a base body having a central axis and secured to the exhaust pipe, with a bearing part having a longitudinal axis to accommodate the exhaust probe, wherein the bearing part and the base body are at least two-part and the bearing part can be secured in the base body in various positions, P | 10-16-2014 |
20140165544 | MODULAR MANIFOLD FOR MOTOR VEHICLES - A modular exhaust manifold | 06-19-2014 |
20140075927 | HEADER FOR CURVED PIPES - A header for several curved pipes of a motor vehicle carrying exhaust gas, including a first shell and a second shell, which can be connected to one another in a sealed manner by a shell connection that forms a connection plane (E), at least one outlet port for connecting to an exhaust pipe of an exhaust gas system, and several curved-pipe connection ports for connecting the curved pipes, wherein the outlet port is designed as a passage within the respective shell and at least one first curved-pipe connection port is provided, which is designed as a passage within only one of the two shells. | 03-20-2014 |
20130202887 | METHOD FOR ENCASING A BODY OF AN EXHAUST GAS SYSTEM - A method for encasing a body of an exhaust gas system with a housing which is wound around the body. Using a winding method, the body is placed in a loop formed by a belt-shaped conveyor element that can be driven in a conveyor device, wherein the conveyor element is seated against the outer casing face at a wrapping angle u of at least 270 degrees. Starting with a first edge, the metal strip is then introduced in a conveyor device between the body and the conveyor element, is drawn into the gap between the body and the conveyor element and is bent around the body until the body is encased at least twice by the metal strip. | 08-08-2013 |
20120280161 | VALVE FLAP DEVICE - A valve flap device having at least one valve housing having a shaft comprising a bearing surface and a valve axis, the shaft being rotationally supported about the valve axis by means of the bearing surface in the valve housing. A bearing element having a sliding bearing surface, wherein the bearing surface of the shaft contacts the sliding bearing surface. A bearing housing provided on the valve housing, in which the bearing element is supported at least in the radial direction to the valve axis, wherein the bearing element has an outer surface contacting the bearing housing. The support of the shaft is intended to be sufficiently tightly sealed, even for gaseous media, while simultaneously ensuring precise and statically determinate support. To this end, the bearing element is designed as a separate component coupled to the bearing housing about the valve axis with respect to the circumferential direction, such that the relative position between the bearing element and the bearing housing does not change in the circumferential direction when the shaft is rotated. | 11-08-2012 |
