摘要： A fuel injector for an internal combustion engine having a crankshaft is disclosed. The fuel injector has plunger to displace fuel and an electronically controlled spill valve. The fuel injector also has a nozzle member having at least one orifice and a valve needle disposed within the nozzle member, and movable against a spring bias to selectively inject pressurized fuel through the at least one orifice. The fuel injector also has an electronically controlled check valve. The valve needle is automatically moved to inject pressurized fuel when the pressure of the fuel within the fuel injector reaches a predetermined valve opening pressure determined by a spring bias. Valve elements of the electronically controlled spill and check valves are both in a flow blocking position before the pressure of the fuel within the fuel injector reaches the predetermined valve opening pressure. Injection terminates when the valve element of the electronically controlled check valve is moved to a flow-passing position.

摘要： A fuel injector includes first and second valves and a solenoid including a solenoid coil and an armature assembly wherein the first and second valves are coupled to the armature assembly. A solenoid drive circuit is coupled to the solenoid coil and delivers a first current waveform portion to the solenoid coil at a first time to cause the armature assembly to operate the first valve without operating the second valve. A second current waveform portion different than the first current waveform portion is applied to the solenoid coil at a second time later than the first time to operate the second valve.

摘要： A fuel injector comprises an injector body which defines a nozzle chamber that is separated from a plurality of outlet orifices by a conical valve seat. An outwardly opening valve member, which is at least partially positioned in the injector body, includes a closing hydraulic surface exposed to fluid pressure outside the injector body. The valve member is movable between a closed position, in which the conical valve seat is closed, and an open position.

摘要： A control valve, preferably for use with a fuel injector, includes a valve body defining a solenoid cavity, an inlet passage, an outlet passage and a metering passage extending between the solenoid cavity and the outlet passage. A solenoid is mounted in the solenoid cavity. A valve member has one end attached to the solenoid and is positioned to reciprocate in the valve body between an open position in which the inlet passage is opened to the outlet passage and a closed position in which the inlet passage is closed to the outlet passage. The inlet passage is in fluid communication with the solenoid cavity via the metering passage when the valve member is in its open position. Appropriate sizing of the metering passage can prevent secondary injections by providing adequate pressure relief to the solenoid cavity while also substantially damping any pressure waves that may travel to the solenoid cavity through the metering passage.
摘要翻译： 优选地与燃料喷射器一起使用的控制阀包括限定螺线管腔的阀体，入口通道，出口通道和在螺线管腔和出口通道之间延伸的计量通道。 螺线管安装在螺线管腔中。 阀构件具有附接到螺线管的一端，并且定位成在阀体中在入口通道与出口通道打开的打开位置和入口通道关闭到出口通道的关闭位置之间往复运动。 当阀构件处于其打开位置时，入口通道经由计量通道与螺线管腔流体连通。 计量通道的适当尺寸可以通过向螺线管腔提供足够的压力释放来防止二次注射，同时还基本上阻尼可能通过计量通道行进到螺线管腔的任何压力波。
