- the cover can also be used for fastening described or further valves and / or sensors.
- an electrically operated heater and a temperature sensor for example integrated in the base body, can be provided, in particular in order to keep the reducing agent line in the base body always at sufficiently high temperatures to prevent the reducing agent from freezing.
- the heating can also be accomplished by engine cooler of the motor vehicle engine, which flows through channels to be provided in the base plate for this purpose.
- the filter 18 can also optionally be designed to be electrically heated.
- the quantity control of the reducing agent to be conveyed can, instead of using a metering pump, as described above, optionally also take place via a simple pump in combination with a pressure control valve, which connects the reducing agent line 28 to the tank via a line, not shown, provided the pressure sensor 24 too high a pressure registered.
- a pressure control valve which connects the reducing agent line 28 to the tank via a line, not shown, provided the pressure sensor 24 too high a pressure registered.
- an overpressure valve can also suffice for this.
- the control unit can additionally optionally control an optional heating device for the connecting line and / or a metering device.
- FIG. 2 shows a unit, referred to as Zumessmodul, arranged on an exhaust pipe 30 'metering device 32, wherein electrical lines are not shown in detail, for example, for controlling the metering valve and possibly also for controlling the cooling means described below.

- the reducing agent sucked out of the tank by the reducing agent delivery module reaches the metering module 32 via the connecting line 38 and can be metered into the exhaust gas flow here via the metering valve 34.
- the cooling device branches off part of the reducing agent flowing in via the connecting line for cooling the metering valve, and the return line 62 leads the reducing agent used exclusively for cooling back to the reducing agent tank 12.
- the cooling device can also be supplied with separate coolant;
- the line 62 shown in FIG. 2 does not represent a reductant return line, but rather a double line for supplying or removing coolant, for example the cooling water of the motor vehicle.
- connectors can be connected to connect exhaust gas sensors for nitrogen oxides, ammonia and / or hydrocarbon and / or from exhaust gas temperature sensors, which link the sensors to the control unit via further electrical lines, for example, running parallel to the connecting line 38.
- the connecting line can be equipped with an electrical heater in order to reliably prevent the reducing agent from freezing.
