Abstract: The present invention relates to an exhaust gas cleaning device (2) of an exhaust system (1) of a combustion engine, more preferably of a motor vehicle, with a catalytic converter unit (3) having a catalytic converter support pipe (7) and at least one oxidation catalytic converter element (8) mounted in the catalytic converter support pipe (7), and with a particle filter unit (4) having a particle filter support pipe (11) and at least one particle filter element (12) mounted in the particle filter support pipe (11). A simple handling with simple construction can be achieved with a receiving pipe (5) in which one of the support pipes (7, 11) is axially inserted, and with a clamp connection (6) which sets the receiving pipe (5), the catalytic converter support pipe (7) and the particle filter support pipe (11) against one another.

Abstract: The invention relates to an exhaust system for an internal combustion engine, in particular in a motor vehicle, comprising an exhaust line that carries the exhaust gas, an SCR catalyst system arranged in the exhaust line and an injection device arranged on the exhaust line upstream from the SCR catalyst system for injecting an aqueous urea solution into the exhaust line.

Abstract: The present invention relates to an exhaust system (1) for an internal combustion engine (3) having at least one exhaust gas line (2) that carries exhaust gas and having an injection device (4) for spraying a liquid into the exhaust gas line (2). Downstream from the injection device (4) a vaporizer device (7) which has at least one tubular sheet metal body (8) downstream from the injection device (4), said sheet metal body extending in the longitudinal direction of the exhaust gas line (2) and causing an improved vaporization of the liquid sprayed into the exhaust gas line. In addition, at least one clamp device (12) which is designed like a spring is provided, securing the vaporizer device (7) in the exhaust gas line (2) and/or bracing it elastically against the exhaust gas line.

Abstract: The invention relates to a static mixer for an exhaust system of an internal combustion engine. The mixer has a wall structure that is arranged across the directional of flow in a pipe and has several layers of a corrugated sheeting material laying across one another in the direction of flow. The cells through which the flow can pass in the direction of flow are provided between the sheeting material of neighboring layers. The sheeting material has baffles for all or several of the cells. The baffles are arranged on the sheeting material so that they are arranged on their outgoing flow side in the case of said cells and extend in the direction of flow and across it.

Abstract: A mixing and/or evaporating device (7) is provided for an exhaust system (3) of an internal combustion engine (1), especially in a motor vehicle. The mixing and/or evaporating device (7) has a tubular body (8), at one axial end of which a plurality of blades (9) are arranged, which blades are located adjacent to each other in the circumferential direction, project radially inwardly and have angles of incidence in relation to one another in the axial direction. For manufacture at a low cost, the tubular body (8) is manufactured together with the blades (9) from a single sheet metal body (11) by shaping.

Abstract: A clamp joins two tubular bodies that are in contact with one another with radially protruding flanges. The clamp has a tensioning section for clamping the clamp in the circumferential direction, a tensioning device for introducing tensile forces oriented in the circumferential direction into the tensioning section, bridging a radial clamp opening in the circumferential direction and a holding section which reaches around the flange in the circumferential direction in the installed state, is attached to the flange on the outside radially and extends around it axially on both sides, clamping them axially against one another. The holding section may be formed by several spring elements that act axially and are arranged side-by-side in the circumferential direction and may be designed and dimensioned so that they are capable of following thermally induced expansions and shrinkage of the flanges with spring elasticity in the installed state of the clamp.
