Abstract
A component of an exhaust system has a tubular housing for passing exhaust gases of an internal combustion engine. A first pressure inlet pipe extends from the outside into the tubular housing and has an opening that is directed towards an exhaust gas flow in such a way that a back pressure can be built up in the pressure inlet pipe by the exhaust gas flow. A second pressure inlet pipe extends from the outside into the tubular housing and has an opening that is directed towards the exhaust gas flow in such a way that a lower pressure can be built up in it than the dynamic pressure of the first pressure inlet pipe. The first and second pressure inlet pipes have connections outside the tubular housing that can be connected to a control unit of a vehicle.
Claims6
A component of an exhaust system comprising a tubular housing for passing exhaust gases of an internal combustion engine, comprising:
- a first pressure inlet pipe extending from the outside into the tubular housing, the opening of which is directed towards an exhaust gas flow in such a way that a back pressure can be built up in the pressure inlet pipe by the exhaust gas flow, and
- a second pressure inlet pipe which extends from the outside into the tubular housing, the opening of which is directed towards the exhaust gas flow such that a pressure lower than the dynamic pressure of the first pressure inlet pipe can be built up in it,
- wherein the first and second pressure inlet pipes have connections outside the tubular housing which can be connected to a particle filter control unit of a vehicle,
- wherein the size of the opening of the first or second pressure inlet pipe, the orientation of the opening of the first or second pressure inlet pipe in relation to the exhaust gas flow, or the positioning of the pressure inlet pipe within the tubular housing are matched to one another such that the differential pressure for the control unit is recognized as permissible without a particulate filter being installed, and that the housing has the external shape and the connections of a particle filter so that it can be used as a replacement component, wherein the first pressure inlet pipe has an opening which is directed against the direction of the exhaust gas flow in the tubular housing, so that a part of the exhaust gas flow presses into the opening of the first pressure inlet pipe.
