摘要： A fuel injection system is disclosed for an internal combustion engine that has multiple combustion chambers and a camshaft which cyclically imparts pressurization energy to and recovers pressurization energy from fuel being supplied to the engine. The fuel injection system includes a plurality of unit injectors, a camshaft linkage which simultaneously reciprocates pressurizing plungers of a set of at least two unit injectors and an interconnecting line which allows selective fluid interconnection between fuel pressurization chambers formed within the unit injectors. The interconnection line allows fluid linkage of the volume of fuel which is simultaneously pressurized and depressurized within the interconnected fuel pressurization chambers of a first set of unit injectors.

摘要： A strategy for quantifying and compensating for between-engine variations in engine static timing, fuel pump phasing and overall system bandwidth includes a control circuit operable to manage a fuel control system including a high pressure, cyclically operable fuel pump and at least one fuel injector operable to supply fuel to an internal combustion engine from a fuel collection unit. In one embodiment, the strategy of the present invention is operable to determine peak values of the fuel pressure within fuel collection unit and corresponding engine position values for a number of different engine speeds and solve a corresponding model-based system of equations to determine a combined engine static timing and fuel pump phasing error as well as a first overall system bandwidth value. In another embodiment, the strategy of the present invention is operable to determine peak values of the pressure within a combustion chamber of the engine along with associated engine position values for a number of different engine speeds and solve for the engine static timing error alone and/or a second overall system bandwidth value. In yet another embodiment, the two foregoing strategies may be combined to produce separately the first and second bandwidth values as well as the individual engine static timing and fuel pump phasing error values. In any case, the computed error and bandwidth values may be used to improve the accuracy of sampled engine and/or fuel control system parameters as they relate to engine position.

摘要： An improved plunger and barrel assembly is provided which includes a plunger reciprocally mounted in a cavity formed in the barrel and a leakage flow reduction device positioned in the cavity for reducing fluid leakage flow around the plunger thus increasing system efficiency. The leakage flow reduction device includes a sealing sleeve removably mounted in the cavity between the plunger and the barrel, which includes a bore for slidably receiving the plunger to form an annular clearance gap between the plunger and the bore. The sealing sleeve is designed to resiliently flex in response to fluid pressure forces to reduce the annular clearance gap so as to minimize fluid leakage through the annular clearance gap. The sealing sleeve is formed as a separate piece from the barrel to permit simple, low cost replacement. The sealing sleeve is preferably applied to a fuel pump having a pump plunger for pressurizing fuel in a high pressure chamber.

摘要： A system for estimating a quantity of parasitic leakage of a fluid from a fluid collection unit includes a pressure sensor and a control circuit. The pressure sensor is coupled to the fluid collection unit and configured to produce a pressure value indicative of the pressure of the fluid collection unit. The control circuit is operable to determine a change in pressure value of the fluid collection unit and estimate the quantity of parasitic leakage based on the change in pressure value. The control circuit may also be operable to determine a bulk modulus value of the fluid and estimate the quantity of parasitic leakage based on the change in pressure value and the bulk modulus value.

摘要： A fuel control system for an internal combustion engine including injected fuel quantity estimation includes a fuel pump responsive to a fuel pump command to supply fuel to a fuel collection unit. A pressure sensor is provided for producing a pressure signal indicative of the pressure of fuel within the collection unit throughout a fuel injection event, and an engine position sensor is provided for producing an engine position signal indicative of a crank angle of the engine relative to a reference crank angle. A control circuit includes means responsive to the pressure signal and a desired fueling value for producing an initial fueling command, and further includes a fuel quantity estimation block responsive to the pressure signal, the engine position signal and a final fueling command to produce a fuel quantity estimation value. The final fueling command is computed by the control circuit as a function of the initial fueling command and the fuel quantity adjustment value to which the injector is responsive to supply fuel to the combustion chamber.

摘要： A fuel injection pressure control system includes a control strategy operable to measure or estimate actual fuel injection pressure and control the operation of a fuel supply pump to thereby quickly and accurately control fuel injection pressure. The control strategy includes a closed-loop control strategy operable to compensate for instantaneous changes in system non-linearities, including fuel pump non-linearities and the like, and an open-loop control strategy operable to compensate for all system variations as well as system non-linearities, including between-engine variations in system operating parameters and other noise factors including deteriorating conditions, changes in environment and the like. Each strategy includes an adaptive controller operable to update one or more control parameters to thereby guarantee closed-loop stability, provide for fast and accurate system response during transient events, and minimize overshoots and undershoots.

摘要： A process, system, and component configuration are described that discourages customer acceptance/use of will-fit, reconditioned, and counterfeit product components, by determining whether or not a serviceable product component is genuine. If a component is determined to not be genuine, then appropriate action may be taken to warn operators and document such findings. For example, one or more markers are disposed or otherwise put on the subject serviceable product component and serves as a targeted feature, and/or a particular characteristic of the filter itself is identified as the targeted feature. A sensor is used to detect the targeted feature and obtain information unique to the serviceable product component. The targeted feature(s) identifies the particular serviceable component as genuine and forms the basis for determining whether a genuine component has been installed. In some circumstances, a fluid filter product is the component that is the subject detection.

摘要： In accordance with preferred embodiments of the invention, a disc-shaped contact pad of ceramic material is disposed within a recess formed in the top surface of a metal valve crosshead. The pad is held in the recess by a retainer that clips onto the crosshead. The retainer is designed to maintain only a light pressure on only a narrow shoulder of the pad to keep it seated, and does not, itself, experience any dynamic loading. Furthermore, by the provision of a circumferential clearance between the pad and both the wall of the crosshead recess and the retainer, the need for precision machining of the ceramic material can be avoided. Additionally, a reduction of frictional sliding forces imposed on the crosshead, and in turn upon the valves, by the rocker lever is achieved by the ceramic pad, so that resultant frictional side loading is not imposed on adjacent valve components to a significant extent.

摘要： A ceramic-metal composite structure which minimizes tensile ceramic loads and accommodates differences in thermal expansion characteristics between a metal member and a ceramic member without reliance on precise feature control for either member. The composite includes a mechanical retainer which allows a loose fitting relationship between the metal and ceramic members. The ceramic member is secured within a receiving bore in the metal member by the retainer in a manner which eliminates the need for precise machining of the ceramic and metal members. The metal member may be configured to accept either an internal or an external mechanical retainer element. The composite ceramic-metal structure of the present invention finds particular utility in forming a durable wear-resistant interface in internal combustion engine actuator or actuating components, such as compression brake master pistons.
