摘要:
A heating module (1) for an exhaust-gas purification system connected to the outlet of an internal combustion engine comprises a catalytic burner, with an HC injector (14) and with an oxidation catalytic converter (12) positioned downstream of the HC injector (14) in the flow direction of the exhaust gas, for supplying thermal energy to an exhaust-gas purification unit of the exhaust-gas purification system. It is provided here that the heating module (1) has a main section (2), a secondary section (3) which comprises the catalytic burner (12, 14), and a device (4, 5) for controlling the exhaust-gas mass flow flowing through the secondary section (3). In a first embodiment, the main section (2) has, in the inlet region or the heating module (1), an overflow pipe portion (6) which has overflow openings (7), between which overflow diverting chambers (8) is situated, parallel to the main section (2) of the heating module (1), the secondary section portion (11) with the oxidation catalytic converter (12). In another embodiment, it is provided that the secondary section (3) has, at the inlet side and outlet side, in each case one diverting chamber (8) which extends in the radial direction from the main section (2), between which diverting chambers (8) is situated, parallel to the main section (2) of the heating module (1), the secondary section portion (11) with the oxidation catalytic converter (12).

摘要:
A reducing agent dosing device for delivering a reducing agent into the exhaust gas system 8 of the internal combustion engine 2 of a motor vehicle, comprising a reducing agent tank 3 connected to the exhaust gas system 8 via a supply line 5, 7 with a dosing valve 6 for delivering a specific quantity of reducing agent. The dosing valve 6 is disposed at a distance from the exhaust gas system 8 in the supply line 5, 7 and the output of the dosing valve 6 terminates in a mixing chamber 7. Compressed air, provided by the charge air of a charging group 10 of the internal combustion engine 2, flows though the mixing chamber in the direction toward the exhaust gas system 8 to mix the reducing agent output with an air stream.
