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. Further, if the fuel pressure in the fuel chamber is decreased, the fuel housing contracts and the pressure in the fuel chamber is increased. That is, the fuel housing functions as a kind of damper. 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.
