摘要： A novel and improved closed nozzle injector is provided which effectively and accurately controls the timing and rate of fuel injection while minimizing parasitic losses and needle valve element wear. The closed nozzle injector includes a needle valve element movable between open and closed positions, an outer control volume, an injection control valve for controlling the flow of pressurized fuel from the outer control volume to affect opening and closing of the needle valve element and a needle valve biasing feature for optimizing the speed of needle valve opening and closing. The needle valve biasing feature includes an inner guide portion formed on the needle valve element with a larger diameter than an outer guide portion, an inner control volume, and an inner restriction orifice for restricting the flow of pressurized supply fuel to the inner control volume to create a fuel pressure bias closing force which advantageously slows down the opening of the needle valve element. The fuel pressure bias closing force increases as the needle valve element opens thereby causing the needle valve element to hover in an open position without contacting a hard stop. The inner control volume and inner restriction orifice also result in a hydraulic damper effect which slows the closing motion of the needle valve element toward the end of the closing event thereby permitting higher needle closing velocity earlier in the closing event.
摘要翻译：提供了一种新颖且改进的闭合喷嘴喷射器，其有效且精确地控制燃料喷射的时间和速率，同时最小化寄生损耗和针阀元件磨损。闭合喷嘴喷射器包括可在打开和关闭位置之间移动的针阀元件，外部控制容积，用于控制来自外部控制体积的加压燃料流动以影响针阀元件的打开和关闭的喷射控制阀以及针阀门偏置功能，用于优化针阀打开和关闭的速度。针阀偏压特征包括形成在针阀元件上的内引导部分，其具有比外引导部分更大的直径，内控制容积和用于限制加压供给燃料流到内控制体积的内限制孔产生燃料压力偏压闭合力，其有利地减慢针阀元件的开度。燃料压力偏压闭合力随着针阀元件打开而增加，从而使针阀元件在不接触硬止动件的情况下悬停在打开位置。内部控制体积和内部限制孔口也导致液压阻尼器效应，其减慢针阀元件关闭事件结束时的关闭运动，从而允许在关闭事件中提前更高的针闭合速度。

摘要： An improved sensor and sensor assembly is provided which permits the easy removal of the sensor from its mounting bore even in the presence of corrosive residue in the mounting bore. The sensor assembly includes an elongated sensor body having an annular tapered portion with a frusto-conical shape for positioning in a mounting bore having a complementary taper. As the sensor is removed from the mounting bore, the annular gap between the sensor and inner wall of the mounting bore will gradually increase at any point along the sensor body thereby increasingly separating any corrosive residue accumulated on the opposing surfaces. In addition, a seal assembly is provided which effectively vents gas pressure from the annular gap between the sensor and the mounting bore without damaging the seal and while ensuring the seal returns to its fully sealed position thereby preventing contaminants from entering the bore throughout engine operation.

摘要： A fuel injector including a floating sleeve control chamber is provided which effectively minimizes friction and wear, and thus prevents stiction, of a nozzle valve element by avoiding the need to align two bore guiding surfaces for the element. The floating sleeve control chamber includes a floating sleeve positioned on a control piston formed integrally with a nozzle valve element and positioned in a cavity. The floating sleeve is sized with an outer extent or diameter sufficiently less than the size of a surrounding cavity wall so as to permit lateral movement of the floating sleeve and thus movement of the control chamber. Only the nozzle valve element guiding bore surfaces control the alignment of the nozzle valve element relative to its seat while the floating sleeve effectively forms and seals a floating control chamber. The floating sleeve may be formed from one or more sleeve sections. In addition, the floating sleeve may include one or more swivel joints to accommodate perpendicularity errors between the components.

摘要： An automatic water drain and priming pump for a fuel system in which a reversible pump is operable in a first direction to pump separated water out of a fuel filter and into a water drain, and further operable in a second (opposite) direction to pump fuel into the fuel filter in order to prime the fuel pump. Operation of the pump in the first direction to drain water from the fuel filter is initiated by water-in-fuel sensors within the fuel filter. Operation of the pump in the second direction to prime the fuel pump is initiated by manual activation of a switch during servicing of the fuel filter.

摘要： A fuel injector having a nozzle with improved cooling including a retainer and a nozzle housing received therein. The nozzle housing includes a nozzle shank, an outer peripheral surface and at least one injection hole at a tip of the nozzle shank. The nozzle shank is positioned in a nozzle support portion of the retainer. In one embodiment, the outer peripheral surface of the nozzle shank is tapered, and the inner peripheral surface of the nozzle support portion is correspondingly tapered and sized to engage the outer peripheral surface of the nozzle shank along a tapered interface. In another embodiment, the inner peripheral surface of the nozzle support portion has a diameter smaller than a diameter of the outer peripheral surface of the nozzle shank so that an interference fit exists at a seal interface. In yet another embodiment, a nozzle seal seals an interface between the inner peripheral surface of the retainer and the outer peripheral surface of the nozzle shank to thereby prevent entry of hot gases into the interface. In another embodiment, the nozzle support portion is provided on a nozzle sleeve.

摘要： An improved fuel injector is provided which effectively controls fuel injection events using two injection control valves which operate in series to control the movement of a nozzle valve element. An outer injection control valve and actuator assembly operates to control fluid pressure in a control volume adjacent an inner injection control valve thereby controlling the movement of the inner control valve which, in turn, controls fuel pressure in an inner control volume adjacent one end of the nozzle valve element. A particular design of the inner injection control valve prevents control valve oscillations thereby minimizing unwanted fuel injection variations.

摘要： An improved sealing boot for a spark plug assembly is provided which includes a sealing and venting feature capable of preventing pressurized contaminants from reaching the spark plug by effectively sealing the spark plug mounting bore while permitting pressurized gas accumulating in the plug well to be vented to the engine overhead. The sealing and venting feature includes at least one annular sealing rib formed on the outer surface of the boot. The radial length and width of the sealing rib, and the resiliency of the material forming the rib, are selected to cause the rib to deflected outwardly an optimal degree, when the assembly is positioned in the bore, and to engage the bore wall with a sealing force so as to permit the desired sealing and venting. The optimal deflection causes the creation of an additional sealing force due to the pressure of fluid against the deflected portion of the rib thereby ensuring sealing.
