    摘要: In an internal-combustion engine exhaust gas system, a storage tank stores the reducing agent, a supply pipe connects the storage tank to a metering unit which introduces the reducing agent into the exhaust gas system. A pump mechanism within the supply pipe conveys the reducing agent. A pressure sensor detects the pressure in the supply pipe downstream of the pump, and a pressure-releasing device has a return pipe connected to the storage tank and comes off the supply pipe. A first valve system is arranged in the supply pipe. A section of the return pipe is located at a higher level than the return pipe to form a storage volume for air present in the supply pipe. A second valve system is arranged in the supply pipe to create, when the second valve system is closed, a storage volume for pressurized reducing agent by way of this pipe branch.

    摘要: A heating device for heating a storage device (2) for a complex salt in a motor vehicle includes the storage device (2) for the complex salt and at least one mass-ducting hollow pipe (4). A mass flows through the mass-ducting hollow pipe (4) while the motor vehicle is operating and heats up while the motor vehicle is operating, and is thermally coupled to the storage device (2) for the complex salt in such a way that the heated mass in the mass-ducting hollow pipe (4) will heat the storage device (2) for the complex salt.
