Fuel sensor device for identification of different fuel types, comprises housing, heating device for heating fuel during operation of device and unit for determination of characteristic temperature of fuel

摘要

The device (3) comprises a housing, by which the fuel flows inside and flow through during refueling, a heating device for heating the fuel during the operation of the device and a unit for the determination of a characteristic temperature of the fuel. The heating device has a negative temperature coefficient heating element or a positive temperature coefficient heating element, which is projected into sections of the housing. An independent claim is also included for a safety device for the avoidance of a false refueling of a motor vehicle.
