Abstract: A mixer is provided for mixing exhaust gas (A) flowing in an exhaust gas-carrying duct (14) of an internal combustion engine with reactant injected into the exhaust gas-carrying duct (14). The mixer includes a mixing body (22) with a reactant-receiving duct (34), an exhaust gas inlet opening device (54) with a plurality of exhaust gas inlet openings (56) leading to the reactant-receiving duct (34), and at least one releasing duct (40, 42) leading away from the reactant-receiving duct (34) with a releasing duct opening (48, 50) for releasing a reactant/exhaust gas mixture from the mixer body (22). An electrically energizable heater (68) is provided at the mixer body (22).

Abstract: A reactant introduction device, for introducing reactant into an exhaust gas stream of an internal combustion engine, includes a reactant introduction housing (16) with a reactant introduction space (20) surrounded by a housing wall (18). The housing wall (18) includes an incoming flow wall area (30) positioned upstream in relation to an exhaust gas flow direction (A), an outgoing flow wall area (32) positioned downstream, in relation to the exhaust gas flow direction (A) and two side wall areas (34, 36) between the incoming flow wall area (30) and the outgoing flow wall area (32). At least one flow-through opening (72, 74, 76) is provided in at least one side wall area (34, 36) or/and in the outgoing flow wall area (32). A reactant injection device (28) injects reactant into the reactant introduction space (20) in a reactant introduction direction (E) onto a heatable reactant release element (48).

Abstract: An exhaust system, especially for an internal combustion engine of a vehicle, includes an exhaust gas-carrying duct (14) and a reactant injection device (20) for injecting reactant (R) into exhaust gas (A) flowing in the exhaust gas-carrying duct (14). Downstream of the reactant injection device (20), a mixer device (22) supports the mixing of reactant (R) injected by the reactant injection device (20) with exhaust gas (A) flowing in the exhaust gas-carrying duct (14). Downstream of the reactant injection device (20) and upstream of the mixer device (22), a reactant heating device (24) extends in the exhaust gas-carrying duct (14). The exhaust gas (A) flows in and reactant (R) injected through the reactant injection device (20) flow around the heating device (24).

Abstract: A mixer for an exhaust gas duct system of an internal combustion engine includes a flow channel element (16) with a flow channel (14), through which exhaust gases can flow in a main direction of flow (S). At least one mixer element (12) in the flow channel element (16) is movable in the flow channel element (16) to change a mixing effect.

Abstract: A mixing and/or evaporating device (12) for an exhaust system (5) of a combustion engine (1), in particular of a motor vehicle, includes a support body (19), which encloses a flat cross section through which a flow can flow running transversely to the axial direction (20) of the device (12) in the circumferential direction (32). The support body (19) comprises two long side walls (21, 22) located opposite each other and two short side walls (23, 24) located opposite each other, wherein the short side walls (23, 24) each connect the two long side walls (21, 22) with each other. At least on one long side wall (21, 22) at least on one axial end (26, 27), a plurality of guide blades (25) is arranged. The guide blades (25) stand away in a direction of the other long side wall (21, 22) and are angled relative to the axial direction (20).

The support body (19) has at least one guide blade (25, 28) which extends away transversely to the axial direction (20). An improved efficiency is obtained with the guide blade (25) having a roof-shaped profile (29), including two guide surfaces (30, 31) that are interconnected via a ridge (32) or apex.
