摘要： A fuel injection control device includes an electric controller controlling an opening and closing of an injector by energizing a coil in the injector, and a booster circuit boosting a battery voltage to generate a boost voltage. The electric controller includes a valve-opening control unit applying the boost voltage and then applying the battery voltage to the coil to execute a valve-opening control to generate a required valve-opening force, an open valve maintenance control unit applying the battery voltage to the coil to execute an open valve maintenance control to generate an open valve maintenance force and is smaller the required valve-opening force, after the valve-opening control, and a current correction control unit executing a current correction control to correct a maximum value of a current flowing through the coil when the boost voltage is applied in the valve-opening control, according to a decreasing quantity of the battery voltage.

摘要： A first spring axially urges a needle valve toward an injection hole. A second spring axially urges a movable core toward a stationary core with an urging force that is smaller than an urging force of the first spring. A stopper is placed on one axial side of the movable core where the injection hole is located. The stopper limits movement of the movable core toward the injection hole to limit an amount of compression of the second spring.

摘要： A closed nozzle fuel injector is provided which effectively controls the fuel injection flow rate, especially during an initial portion of an injection event, while also permitting accurate control over pilot and/or post injection flow rates at all operating conditions thereby advantageously reducing emissions and combustion noise. The injector includes a rate shaping orifice to restrict fuel flow during an initial portion of an injection event and a rate shaping sleeve mounted for movement to cause a greater flow of injection fuel during a later portion of the injection event. A damping chamber and orifice are also provided to control movement of the rate shaping sleeve.

摘要： A fuel injection system having a high pressure fuel injection pump whose high-pressure pumping is determined by an electrically controlled valve that controls a relief conduit, and the phase of the fuel injection is determined by the closure of this valve. To execute an injection that is subdivided into a preinjection and a main injection, and to simplify triggering of the electrically controlled valve, a cam that drives the pump piston is shaped such that the cam furnishes a range (P), in which the pump piston, to interrupt the injection between the preinjection and the main injection, remains in or moves back to its then-reached position.

摘要： An injector is disclosed which comprises a valve needle engageable with a seating. A spring urges the needle towards its seating, the spring engaging a spring abutment. A pressure backing member positioned within the injector is slidable relative to the spring abutment under the action of the pressure of fuel applied thereto. The pressure backing member is engageable with a surface associate with the needle to urge the needle towards its seating. The slidable pressure backing member reduces the pressure in the pumping chamber both prior to and after termination of the injection process. Also, the backing member maintains the pressure in a fuel supply passage of a low level to enhance the efficiency of the injector.

摘要： A fuel injection nozzle for preinjection and main injection has a nozzle holder in which two closing springs are arranged coaxially, one spring acts continuously on the valve needle via a central pressure bolt and the other spring acts on the valve needle, via a pressure ring surrounding the pressure bolt, once the valve needle has passed through a pretravel (h.sub.v). Between the valve needle and the pressure bolt and the pressure ring, an intermediate pressure element which is constructed as a disk is arranged, the outer edge area of the intermediate pressure element does not come into contact with the pressure ring until after the valve needle has passed through the pretravel (h.sub.v), which pressure is supported in the closed position of the valve needle by a shoulder of an intermediate disk. In order to prevent the connection between the low pressure space at the valve needle and the pressure-relieved spring chamber being interrupted in the pretravel position when the intermediate pressure element comes into axial contact with the pressure ring which is supported on the shoulder of the intermediate disk, bridging channels are arranged at least in the intermediate pressure element.

摘要： A cross-section controlled multi-jet injection valve for an air-distributor injection in air-compressing combustion engines is provided. In order to fulfill the more stringent requirements and standards for exhaust fume quality it is necessary to provide a homogenous fuel/air mixture. This is achieved with a valve needle which is provided with an axially and radially oriented key. Due to this key a favorable ratio of injection cross-section to circumference of the respective cross-section is achieved. Accordingly, a division of the injection jet and a mixing with air is provided. Due to correspondingly adjusted pressure springs the injection pressure at varying amounts of fuel to be injected is kept constant which furthermore provides a constant homogeneity of the fuel/air mixture. Thus an excellent exhaust fume quality is obtained for the entire performance range.

摘要： A fuel injection nozzle for internal combustion engines having a nozzle body secured on a nozzle holder, and a valve needle that is axially displaceable in the nozzle holder, the valve needle being raised from a valve seat for fuel injection by the fuel pressure, counter to a closing spring assembly of first and second helical compression springs disposed in series. The total stroke of the valve needle is divided into a prestroke and a remaining stroke. To attain an injection nozzle having the smallest possible outside diameter, the spring chamber receiving the closing springs comprises a blind bore of substantially constant diameter, on a bottom of which the first closing spring is supported. To support the second closing spring, a pressure shoulder part in the form of a ring is inserted into the blind bore; the pressure shoulder part is fixed by deformation of contacting parts of the wall of the nozzle holder. Recesses are machined into the circumference of the pressure shoulder part and for easier deformation of portions of the wall of the nozzle holder in the region of the pressure shoulder part, recesses are machined into the outer wall of the pressure shoulder part, with a portion of the wall of the nozzle holder forming the bottom being deformed to form a form-fitting connection with the recesses of the pressure shoulder part.
