Abstract: In a fuel property detection device, a fuel housing is made of a thin-plate metal member that can be elastically-deformed by a fuel pressure in a fuel chamber. Thus, if the fuel pressure in the fuel chamber is increased, the fuel housing expands and the pressure in the fuel chamber is decreased.

Therefore, in the fuel property detection device, generation of abnormal noise due to fuel pulsation or the like, and a positional change of the electrodes due to the fuel pulsation or the like can be prevented.

The jet actuator directs entrained ambient gas or liquid toward the active surface of the sensor, and the impingement of sample gas or liquid onto the surface of the sensor results in faster response time. Other embodiments are also claimed and described.
