DOSING ARRANGEMENT FOR A LIQUID EXHAUST GAS AFTER-TREATMENT MEDIUM AND DOSING METHOD
The invention relates to a dosing arrangement (3, 30) for a liquid exhaust gas after-treatment medium for the after-treatment of the exhaust gas from an internal combustion engine having an exhaust gas system, particularly for a urea-water solution, having a delivery pump (7) and a dosing module (13...

| description | The invention relates to a dosing arrangement (3, 30) for a liquid exhaust gas after-treatment medium for the after-treatment of the exhaust gas from an internal combustion engine having an exhaust gas system, particularly for a urea-water solution, having a delivery pump (7) and a dosing module (13), wherein the delivery pump (7) is connected to a suction line (23) for drawing in the exhaust gas after-treatment medium from a tank (1); the delivery pump (7) and the dosing module (13) are connected to one another via a pressure line (25) and the exhaust gas after-treatment medium can be fed to the exhaust gas system via the dosing module (13); a recirculation pump (8) connected on the suction side to the dosing module (13) is provided; and the exhaust gas after-treatment medium pumped by the recirculation pump (8) can be returned on the high-pressure side via a line, which is not the same as the suction line (23), to the tank, enabling the lines (23, 25) to be flushed with the exhaust gas after-treatment medium as necessary. The invention further relates to a corresponding method for dosing. |
