摘要： The present invention is an apparatus 10 for hydraulically slowing a member (12), preferably an engine poppet valve, to an acceptable impact seating velocity as the valve (12) is moved from open to closed. The poppet valve (12) has a stem (16) having a first portion (18) connected through a stepped portion (20) to a second portion (22) having a greater cross-sectional area than the first portion (18). The valve (12) rides within a guide body (28) having an opening (34) in an end wall (32) thereof through which the first portion (18) of the stem (16) extends. A hydraulic fluid space (50) is formed by the guide body (28) and the valve (12). As the valve (12) closes, fluid is forced out of the space (50) through a first fluid exit opening (66). As the valve (12) nears its seat (44), the fluid still in the space (50) is forced out through a second fluid exit opening (68) through which the rate of flow is less than the rate of flow through the first fluid exit opening (66). As the valve (12) continues closing, fluid still in the space (50) is compressed, increasing its hydraulic pressure and creating a resistive force to further movement of the poppet valve (12), thereby slowing it to an acceptable impact velocity.
摘要翻译：本发明是一种用于当阀（12）从开放移动到关闭状态时将构件（12）优选地将发动机提升阀液压地减速至可接受的冲击座椅速度的装置10。提升阀（12）具有杆（16），杆（16）具有通过阶梯部分（20）连接到第二部分（22）的第一部分（18），该第二部分具有比第一部分（18）更大的横截面面积。阀（12）在引导体（28）内行进，该引导体（28）在其端壁（32）中具有开口（34），杆（16）的第一部分（18）穿过该开口延伸。液压流体空间（50）由引导体（28）和阀（12）形成。当阀（12）关闭时，流体通过第一流体出口（66）被迫离开空间（50）。当阀（12）靠近其座（44）时，静止在空间（50）中的流体被迫通过第二流体出口（68）排出，流体的流速小于通过第一流体流体出口（66）。当阀（12）继续关闭时，静止在空间（50）中的流体被压缩，增加其液压并产生阻力以使提升阀（12）的进一步运动，从而将其减慢到可接受的冲击速度。

摘要： An improved mechanical joint structure is provided and adapted for positively retaining a heating element within a bore of a body of a glow plug. The glow plug includes a body, a heating element and a ferrule. The ferrule is sealingly positioned radially between an internal surface of the body bore and a peripheral surface of the heating element. The glow plug further includes a compressing structure for positively compressing an internal surface of the ferrule against the peripheral surface of the heating element in response to the heating element being forced into the body bore by, for example, the gas pressure developed in an operating engine combustion chamber.Unlike conventional brazed or interference joints used in typical glow plugs, the present invention provides a normal force (F.sub.n), for sealing the heating element, and an axially-directed frictional force (F.sub.f), for retaining the heating element, which both increase as the heating element is forced deeper into the body bore.

摘要： The service life of conventional glow plugs is extremely short when they are continuously energized at an elevated temperature during engine operation in order to assist ignition of non-autoignitable fuels. Such glow plugs typically fail due to thermal stresses and/or oxidation and corrosion.Herein is disclosed an improved heating element assembly adapted for incorporation in a glow plug. The heating element assembly includes a monolithic sheath having a relatively-thin and generally annular wall defining a blind bore. The heating element assembly further includes a heating device positioned in the blind bore and adapted to emit heat, and a heat transfer device adapted to transfer heat from the heating means to the sheath. The heating device includes a heating filament and a ceramic insulator. THe heating filament is protected against oxidation by being encapsulated in the insulator. The insulator is protected against corrosion by being encapsulated in the sheath. The sheath is formed of a preselected material which is chosen and configured so as to minimize failure of the heating element assembly caused by thermal stresses, oxidation and/or corrosion.

摘要： Conventional direct-injection internal combustion engines having a fuel injector with multiple fuel spray orifices will not completely ignite and burn relatively lower-cetane-number alternative fuels such as 100 percent methanol or ethanol. That is because the fuel spray injection pattern, per se, usually cannot carry or propagate a flame to all the injected fuel which is typically made up of individual fuel streams which are separated by sectors of fuel-deficient intake air. The present fuel combustion system (10) includes a multiple-orifice fuel injector (22), a baffle (138) having a concave surface (146), and a fuel ignition-initiating device (22) such as glow plug positioned generally in spaced relation between the fuel injector (22) and the concave surface (146). The baffle (138) intercepts and temporarily maintains a stoichiometric preselected portion (34,38) of at least one, and preferably two, fuel streams (102,106) in ignitable proximity to the fuel ignition-initiating device (26) to positively start a localized flame (42) of burning fuel. The baffle (138) controlledly reflects and rapidly directs the resultant expanding flame (42) of burning fuel to all of the remaining fuel streams (110) so that they are interconnectedly bridged with the flame (42) and thereby positively ignited.
摘要翻译：具有具有多个燃料喷雾孔的燃料喷射器的常规直喷式内燃机将不能完全点燃和燃烧相对较低十六烷值的替代燃料，例如100％甲醇或乙醇。这是因为燃料喷射喷射模式本身通常不能将火焰携带或传播到通常由燃料不足的进气的扇区分开的单个燃料流组成的所有喷射燃料。本发明的燃料燃烧系统（10）包括多孔燃料喷射器（22），具有凹面（146）的挡板（138）和燃料点火启动装置（22）燃料喷射器（22）和凹面（146）之间的关系。挡板138拦截并临时保持燃料点火启动装置（26）可靠地靠近燃料点火启动装置（26）的至少一个，优选两个燃料流（102,106）的化学计量预选部分（34,38），以积极地启动局部火焰（42）燃烧燃料。挡板138控制地将所产生的燃烧燃料的膨胀火焰（42）快速地引导到所有剩余的燃料流（110），使得它们与火焰（42）相互桥接，从而被积极地点燃。

摘要： A pump and rail assembly includes a plurality of quills that are compressed between quill seats on a pump and an output rail. A rail pressure control valve and a rail pressure sensor are attached to respective ends of the output rail. An inlet throttle valve is attached to a housing of the pump and rail assembly. Depending upon the application, the output rail may supply fuel to a first injection bank that includes a plurality of fuel injectors in a first common rail, and a second fuel injection bank that includes a second common rail and a plurality of fuel injectors. Different engines having different numbers of cylinders may use similar pump and rail assemblies that each include a plurality of quills, a plurality of pumping elements positioned in a pump housing and an output rail. The quills for each of the different engine applications are interchangeable but differ in number. In addition, the pumping elements of each of the different engine applications are also interchangeable but differ in number.

摘要： Although modern diesel fuel formulations are intended to reduce emissions of diesel engines, at least some of those modern fuels tend to have relatively low lubricity levels. The control valve assemblies described herein help to minimize any increased wear that would otherwise result from the use of such low lubricity fuels by providing a valve element, a valve guide, and an insert. The valve element is received within the valve guide and is moveable between an open position and a closed position. The insert forms a first sealed interface and a second sealed interface with the valve element and the valve guide. When the valve element is in the closed position, both of the first sealed interface and the second sealed interface are engaged. When the valve element is in the open position, only one of the first sealed interface and the second sealed interface is engaged.
