    摘要： A sensing apparatus for determining a property of a fuel such as a gasoline and ethanol blend known as flex fuel includes an acetal plastic tube with an inlet, an outlet and a fuel passage in between. One property of the fuel is a dielectric constant. A pair of sensing plates are placed on opposite sides of the tube leaving the fuel passage unobstructed. A processing circuit on a printed circuit board (PCB) is located near to and is connected with the sensing plates. The circuit applies an excitation signal, senses a capacitance, and generates an output signal indicative of a property of the fuel. The sensed capacitance will increase with increasing concentration of ethanol in the fuel flowing through the passage. A shield for reducing EMI surrounds and encloses the sensing plates and the PCB. An interface connector allows the sensing apparatus to output the capacitance indicative signal to an engine controller or the like.

    摘要： An evaporative solenoid valve assembly for use in a vehicle fuel system between a filtration canister and an intake manifold includes a plunger having a plunger body with central-bore and an elastomeric insert molded therein to define a stop cushion at the end of the insert proximal the valve stop and a valve tip at the end of the insert proximal the valve seat. The valve assembly may include a valve stop having a non-conducting insert received in an end proximal the plunger to reduce noise and wear as well as to improve magnetic flux path. Yet another improvement includes an enlarged pre-load spring disposed within the plunger to provide better spring force distribution and plunger to valve seat alignment.
