APPARATUS AND METHOD FOR SENSING MOVEMENT OF FUEL INJECTOR VALVE
摘要
<p>An apparatus and methods are provided for sensing movement of a fuel injector valve of a fuel injection system. The apparatus preferably includes a fuel pump for pumping fuel to flow to a combustion chamber of an engine and a first valve positioned in fluid communication with the fuel pump for allowing fuel to flow directly into the combustion chamber when in an open position. A second valve is positioned in fluid communication with the first valve and the fuel pump for allowing fuel to flow to the first valve when in an open position. A second valve actuator is positioned responsive to desired fuel injection for actuating the second valve. A sensor is positioned to sense movement of the first and second valves and the actuation of the second valve actuator. A movement differentiator is preferably positioned responsive to the sensor for differentiating a time of moving of the first valve from the time of moving of the second valve and the actuation of the second valve actuator.</p>
