An exhaust gas-treating device () for an exhaust system of an internal combustion engine, especially of a motor vehicle, has a housing (), which has a jacket () extending circumferentially on the side and two end-side end bottoms (). Maintenance is simplified with at least one mounting tube (), which passes through one or the first end bottom () and into the outlet end () of which a particle filter () is plugged axially from the outside, with a deflecting housing (). The deflecting housing () contains a deflecting chamber (), and has at least one inlet () communicating with the deflecting chamber () and at least one outlet () communicating with the deflecting chamber (). A fastening device () is provided for detachably fastening the respective inlet () at the respective outlet end () of the mounting tube ().

Exhaust gas-treating device

A particle filter () for filtering exhaust gas in an internal combustion engine includes a housing and a filter element. A simplified installation and/or simplified replacement of the filter element () and/or improved sealing of the housing () results if the filter element () is supported in an inner jacket (), which is supported radially in an outer jacket () and is arranged so as to be axially movable in the outer jacket (). The inner jacket () is axially supported on a ring (), which is supported axially on a cover () that closes an installation opening () of the housing () via at least one supporting element () in order to transmit pressure forces. A muffler () is provided having such a particle filter (), wherein a section of a muffler housing () of the muffler () forms the housing () of the particle filter ().

Particle filter

An exhaust gas treatment device () includes a combustion waste gas inlet pipe (), an outlet pipe, an essentially gas-tight inner housing () fluidically connected with the inlet pipe and fluidically connected with the outlet pipe. The inner housing receives a particle filter (). A connection element () is arranged in a connection area () of the inner housing. The connection area fluidically faces the outlet pipe (), for mechanically connecting the particle filter with the inner housing. An oxidation catalytic converter () is arranged upstream of the particle filter in the inner housing for catalyzing an oxidation reaction of the combustion waste gas. A counterpressure monitoring point () is provided fluidically between the oxidation catalytic converter and the connection element for measuring a counterpressure exerted by the particle filter during the operation of the treatment device. An internal combustion engine () is provided with the treatment device.

Exhaust gas treatment device

The present invention relates to an exhaust gas treatment device for an exhaust system of an internal combustion engine, more preferably of a road vehicle with a housing, in which at least one exhaust gas treatment element is arranged and mounted by means of a bearing mat and with an outlet pipe which is fluidically connected to an outlet chamber formed in the housing. The risk of a contamination of the bearing mat with water can be reduced with a separating bottom which is arranged in the housing and separates the outlet chamber from a collecting chamber. The separating bottom includes several passage openings through which the outlet chamber is fluidically connected to the collecting chamber and which are each enclosed by a collar protruding into the outlet chamber.

An exhaust gas-treating device () for an exhaust system of an internal combustion engine, especially of a motor vehicle, is provided with a housing (), which has a jacket () extending circumferentially on the side and at least one bottom (). The homogenization of the exhaust gas flow is improved with a mixing housing (), which is arranged in the interior space () of the housing () and which has a mixing chamber (). An inlet () of the mixing housing passes through the bottom () and communicates with the mixing chamber (). An outlet () of the mixing housing passes through the bottom () and communicates with the mixing chamber ().

An exhaust gas treatment device () for an exhaust system of an internal combustion engine, especially of a motor vehicle, has a multipart housing (), which contains an oxidation-type catalytic converter unit () and, downstream therefrom, a particle filter unit () one after another in an axial direction extending in parallel to a longitudinal direction () of the housing. The housing () contains an inlet housing part (), which has an exhaust gas inlet () and the oxidation-type catalytic converter unit (), and an outlet housing part (), which has an exhaust gas outlet () and into which the particle filter unit () axially protrudes. The maintenance of the exhaust gas treatment device is simplified if at least two housing parts () axially adjoining each other are detachably connected to one another by means of a clamp connection () and if at least one bracket () is provided, which is axially rigid in relation to the particle filter unit () and which cooperates with at least one such clamp connection (), such that the bracket () is axially fixed at least one housing part () by means of the respective clamp connection ().

The present invention relates to an exhaust gas treatment unit for an exhaust system of a combustion engine, in particular of a motor vehicle, includes a housing, a plurality of exhaust gas treatment elements, which are arranged in the housing and through which a parallel flow is possible. The unit further includes an outlet nozzle, which penetrates a side face of the housing, and an outlet space disposed in the housing, whereby the outlet of at least one of the exhaust gas treatment elements opens into the outlet space. The rigidity and/or effectiveness of the exhaust gas treatment unit can be improved by means of a funnel body disposed in the outlet space, and comprising a funnel surface which is permeable to exhaust gas. The funnel body connects an outlet end of one of the exhaust gas treatment elements with the outlet nozzle.

Exhaust gas treatment unit

The invention relates to an exhaust gas after-treatment device for an internal combustion engine, including a housing into which an exhaust pipe that opens into a mixing chamber penetrates. The mixing chamber is shaped as a pot and reverses a direction of flow of the incoming exhaust gas whereby it returns the exhaust gas radially outside of the exhaust pipe. An open end of the pot-shaped mixing chamber opens into a collecting space which is designed so that it supplies the exhaust gas to at least one downstream SCR catalytic converter.

Exhaust gas aftertreatment device for an internal combustion engine

A muffler has an integrated SCR catalytic converter for an exhaust line of an internal combustion engine, in particular in a motor vehicle The muffler includes a housing which has an intake trumpet on the intake end and an exhaust pipe on the output end. Catalytic converter elements are arranged in the housing with one inlet end in an inlet chamber and with an outlet end in an outlet chamber. An outlet end of the intake trumpet communicates with the inlet chamber. To improve the efficiency of the SCR catalytic converter the inlet chamber is sealed off from the outside and with respect to the intake trumpet and the catalytic converter elements to the extent that in operation of the internal combustion engine with exhaust gas loaded with urea, passing through the intake trumpet into the inlet chamber, the exhaust gas leaves the inlet chamber only through the catalytic converter elements.

Muffler with an integrated catalytic converter

An exhaust cleaning system for motor vehicles, especially a diesel exhaust cleaning system for medium to heavy utility vehicles. The exhaust cleaning system has an exhaust muffler ( ), a catalytic converter ( ) and an exhaust particle filter element ( ). The exhaust muffler ( ), the catalytic converter ( ) with a U-shaped tubular urea injection element ( ) arranged upstream and an exhaust particle filter element ( ) are integrated in a common housing and designed as a structural, functional unit.
