20080203347 | CONTROL VALVE FOR A GAS DIRECT INJECTION FUEL SYSTEM - A control valve for a gas direct injection fuel delivery system is provided. The control valve comprises a valve body, a poppet movably received within the valve body, and an actuator disposed within the valve body. The valve body has a first fluid path, a second fluid path, and a valve seat providing fluid communication therebetween. The poppet is capable of movement between a first position and a second position. When disposed in the first position, the poppet seals the valve seat to block fluid communication between the first fluid path and the second fluid path. The poppet permits fluid communication between the first fluid path and the second fluid path as the poppet moves from the first position to the second position. The poppet is configured so that a pressure in the first fluid path produces a force that tends to move the poppet toward the second position and a pressure in the second fluid path produces a force that tends to move the poppet toward the first position. The actuator is configured to transition between an activated and a de-activated state. The actuator prevents the poppet from being disposed in the first position when in the de-activated state and the pressure in the second fluid path does not exceed the pressure in the first fluid path by at least a first pressure differential. The actuator permits the poppet to be disposed in the first position when in the activated state. | 08-28-2008 |

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. | 06-18-2009 |
