| 摘要 |
<p>The invention relates to a sensor (2-2IV) for detecting the density and the viscosity of a liquid fuel, in particular for a vehicle, comprising a sensing element (4, 4III, 4IV) placed in contact with said liquid fuel and near a reference element (28, 28I, 28II, 28III, 31), so as to affect the motion of the liquid fuel flow by increasing the viscous friction effect of the sensing element (4, 4III, 4IV), so that the resonance frequency of said sensing element (4, 4III, 4IV) will be affected more by the density and viscosity of said liquid fuel.</p> |
