ABSTRACT:
An apparatus for detecting a property of fuel detects the property of fuel at the time of fuel supply. A measuring chamber member is provided to a fuel tank. The greater portion of fuel supplied from a fuel supply nozzle falls down from a fuel supply aperture via a flow outlet into the fuel tank. However, a part of the fuel remains in a measuring space defined between a portion below the flow outlet and a bottom portion. A fuel property detection sensor is fitted to a main body so as to oppose the measuring space. When application of a cap to the fuel supply aperture has been detected by a fuel supply cap sensor, if increase of the remaining fuel amount has been detected by a remaining fuel amount sensor, or if the engine is started, a controller measures the property of the fuel with the fuel property detection sensor.
