摘要： A coolant circuit for an internal combustion engine includes: a coolant pump; at least one coolant line; a radiator; and a coolant cavity delimited in the internal combustion engine. The coolant pump, the coolant line, the radiator and the coolant cavity are filled with a coolant. One or more sensors, configured to monitor the coolant concentration, are fixedly and permanently arranged in and/or on the coolant circuit.

摘要： A sensor for detecting a gas may include a transport layer for transporting ions, a first electrode and a second electrode spaced apart from one another by the transport layer, a heating device controlled by a voltage source, and a second voltage source applying a voltage difference across the electrodes. The transport layer may be conductive for the ions starting from a specific temperature. As a result of applying the voltage difference, ions stream from the first electrode through the transport layer to the second electrode if the first and second electrodes are in contact with the gas. The voltage source may provide a voltage potential of zero volts averaged over time or provide the voltage potential of the first electrode at the heating device.
