The specification discloses a device for introducing a freezable liquid into the exhaust gas system of a motor vehicle. The device may include a tank for accommodating the freezable liquid, a sensor for determining the concentration and/or the filling level of the freezable liquid in the tank, and a dome-shaped ice protector. The sensor may be arranged at least partially in the tank, on the floor thereof. The dome-shaped ice protector may have rounded side faces which run together in the upward direction and have the purpose of protecting the part of the sensor which is located in the tank. The ice protector may be embodied in one piece with a floor plate of the sensor or with the tank floor and the dome of the ice protector has a completely open upper side.

The present disclosure describes a tank comprising an ultrasonic sensor, a first cylindrical reflector, and a second cylindrical reflector. The ultrasonic sensor may be disposed on the floor of the tank for measuring the signal propagation time through a liquid located in the tank and comprise a transmitter/receiver.

A system for determining a regeneration phase of an exhaust gas particulate filter for an internal combustion engine may include a temperature sensor for detecting an elevated exhaust gas temperature, a sensor for detecting the particulate content in the exhaust gas stream exiting from the exhaust gas particulate filter, and a processing device for determining the regeneration phase on the basis of the detected values. A method for determining a regeneration phase of an exhaust gas particulate filter for an internal combustion engine may include detecting an elevated exhaust gas temperature, sampling a signal from a sensor for detecting the particulate content in the exhaust gas stream exiting from the exhaust gas particulate filter, detecting that the particulate content is elevated, and determining the regeneration phase.

A method for on-vehicle functional diagnosis of a soot sensor and/or for detecting further components in the soot in a motor vehicle having an internal combustion engine, the soot sensor connected electrically to an evaluation circuit. To specify a method for functional diagnosis of a soot sensor and/or for detecting further components in the soot, by which it is possible to detect a faulty soot sensor and/or further components in the soot in an economical manner, the evaluation circuit measures a temperature coefficient of the soot sensor and detects the faultiness of the soot sensor and/or the presence of further components in the soot from the temperature coefficient of the soot sensor.
