摘要： An engine control system includes a fuel injector and a sensor that is configured to provide a signal indicative of a temperature. A controller is in communication with the sensor. The controller includes a fuel injector driver in communication with the fuel injector. The fuel injector driver includes a saturated mode and a peak and hold mode. The controller is configured to command the fuel injector driver to control the fuel injector with one of the saturated mode or the peak and hold mode based upon the signal. For a high resistance injector, the peak and hold mode is used in cold weather conditions to break free an injector seal, and then the fuel injector driver reverts to the saturated mode.

摘要： In a method for injecting fuel into the combustion chamber of an internal combustion engine, the fuel is fed by at least one prefeed pump from a tank to at least one high-pressure pump and the high-pressure fuel fed by the high-pressure pump is supplied to the injector, wherein the injector has an injection nozzle with an axially movable nozzle needle protruding into a control chamber which can be fed with fuel under pressure and whose pressure is controlled by a control valve which opens or closes at least one inflow or outflow duct for fuel. Between the prefeed pump and the high-pressure pump, a partial volume of the fuel is branched off as a flushing volume and supplied to a flushing channel of the injector, wherein the flushing volume is directly supplied to the control valve such that the flushing volume flows at least partially through the control valve and preferably mixes with the fuel from the inflow or outflow duct, respectively.

摘要： An injector (10) includes a valve body (16) having an interior portion (18) and a seat (32). An armature tube (20) is in the interior portion. A spring (28) biases a valve member (24) into engagement with the seat. A movable armature (40) is coupled to the armature tube. A calibration member (36) is engaged with the valve member and engaged with the spring. A stator (52) is coupled to an inlet tube (41) and has an end surface spaced from an end surface of the armature in the closed position of the injector, thereby defining an air gap (54) between the end surfaces. A coil (56) is disposed about a portion of the inlet tube. A housing (64) surrounds at least a portion of the coil. Magnetic flux causes the armature and armature tube to push the valve member off the seat.

摘要： In a fuel injection valve, a fuel guide member facing the valve hole is connected to an injector plate, and an annular diffusion chamber is formed between a valve seat member and the injector plate. A pair of first notches, a pair of second notches, and a plurality of closing parts are formed in an outer periphery of the fuel guide member. The first notches are arranged on a first diameter line of the valve hole. The second notches are arranged on a second diameter line perpendicular to the first diameter line. The closing parts are provided between the first and second notches to partially close the valve hole. A plurality of fuel injection holes are dispersally arranged in outside regions corresponding to the closing parts and inside regions corresponding to the first notches. A first tip end corner of the closing part adjacent to the first notch is formed into an edge shape or a minute arc shape, while a second tip end corner of the closing part adjacent to the second notch is formed into a large arc shape. Thus, it is possible to reduce a particle size of injected fuel and improve penetrability.

摘要： In the valve, fuel, flowing down as a valve side flow along the side of the valve, further flows down toward an orifice plate through a fuel path which closes and opens upon forward and backward movement of the valve, and is injected as a mist from each orifice. The valve moves forward and backward by sliding on a valve surrounding portion through a guide portion constituted by plural sliding guides arranged between the valve and valve surrounding portion. Since the sliding guides are tapered from the valve to the surrounding portion, the side flow from the guide portion has a flow velocity distribution biased toward the surrounding portion.
