摘要： An injector is provided which includes a nozzle valve element, a control volume, and an injection control valve for controlling fuel flow from the control volume so as to control nozzle valve movement. Importantly, the injector includes a nozzle valve lift detecting device for detecting nozzle valve lift and providing a nozzle valve element lift feedback signal. In addition, an injection control valve member movement detecting device may be provided for detecting movement of the injection control valve member into open and/or closed positions and generating a control valve member position feedback signal. One or both of the feedback signals may be used for adjusting the timing and/or rate of opening of the injection control valve thereby controlling the timing and/or rate of opening of the nozzle valve element to control the timing and/or rate of fuel injection of subsequent injection events. The nozzle valve element lift detecting device includes positioning the injection control valve for contact by the nozzle valve element and a piezoelectric element for generating the feedback signal. A control device is used to process the feedback signal and adjust control of the injection control valve to achieve reduced emissions.

摘要： One strategy for reducing undesirable emissions from internal combustion engines relates to finding ways to better mix fuel and air prior to combustion. One such method is commonly referred to as homogenous charge compression ignition (HCCI); however, that strategy is problematic in both controlling ignition timing and avoiding overstressing the engine at higher speeds and loads. The present invention addresses these issues by mixing air and fuel vapor within an injector instead of within the engine cylinder. The air/fuel mixture is then injected into the engine cylinder at some desired timing and over some desired duration. Such a strategy permits for lower emissions due to better mixing of air and fuel, while also permitting control over some aspects of combustion timing and duration not apparently possible with a conventional HCCI strategy. The present invention is generally applicable to all internal combustion engines, but especially applicable to diesel engines.

摘要： An improved rotary fuel distributor is provided which effectively dynamically centers the rotor during operation while actively cooling the rotor and refilling fuel passages to minimize cavitation. A pressure balancing system is provided which includes pressure area defining grooves formed adjacent a rotor outlet port to control the pressure gradient in the clearance between the rotor and the distributor housing thereby effectively providing a more predictable force component which can be controlled to more effectively balance the rotor in conjunction with two balancing ports positioned on the opposite side of the rotor from the outlet port. A refill and cooling system is provided to continuously and actively cool the rotor with cool, low pressure fuel throughout rotation thereby displacing the hot fuel with cool fuel and effectively preventing thermal seizure of the rotor. The refill and cooling system also includes passages for effectively refilling delivery passages formed in the distributor housing while intermittently refilling supply passages with cool, low pressure fuel after each injection event.

摘要： The present invention relates to high speed control valves which are especially applicable for use in fuel injection systems. Producing a valve with a quick response time within acceptable packaging constraints and with a structure that allows the valve to be mass produced with consistent performance between valves is extremely problematic. By moving flow restrictions within the valve away from the valve seats, flow forces on the valve member can be reduced, while possibly also permitting a reduction in the necessary travel distance of the valve member to improve response time and other performance characteristics. The valve is particularly applicable in controlling hydraulic pressure applied to the closing hydraulic surface of a direct control needle valve in a fuel injector.

摘要： A three-way valve including a valve housing having a valve chamber and a high pressure fluid supply inlet, high pressure fluid outlet and drain communicating with the valve chamber is disclosed. A movable member is reciprocally received in the valve chamber so as to be reciprocated between first and second positions for selectively fluidically communicating the outlet with either the inlet or drain. A first valve seat is formed in the valve housing and concentrically disposed in the valve chamber for sealing communication between the outlet and drain and a second valve seat is concentrically disposed in a cavity formed in the movable member for sealing communication between the inlet and outlet. A floating pin is received in the movable valve member cavity at a one end of the movable valve member and cooperates with the second valve seat for selectively sealing fluidic communication between the inlet and the outlet. An actuating device is mounted on the valve housing adjacent an end of the movable valve member opposite the floating pin for advancing the movable valve member toward the first position when energized and for allowing the movable valve member to retract to the second position when de-energized.

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。
