摘要： A cam for controlling the injection rate of fuel in a fuel injection system having a four part cam profile is disclosed. The first 120.degree. is the plunger advancement segment. The next 80.degree. is the advanced dwell segment. The next 100.degree. is the plunger retraction segment and the last 60.degree. is the retracted dwell segment. The plunger advancement segment is divided into three subsegments: pre-injection stroke, injection stroke, and overtravel stroke. The pre-injection subsegment achieves minimum velocity and acceleration at the start of injection. In the injection subsegment, the cam follower acceleration is achieved as rapidly as can Hertz stress permits to increase the injection pressure and to achieve the maximum injection rate. The overtravel subsegment achieves a sharp and clean end of injection. Preferably, this cam causes injection of less than 20 mm.sup.3 of fuel per stroke during the first ten cam angle degrees of cam rotation. The injection pressure and the amount of injection are reduced at the beginning of injection, timing is advanced, and optimal control over the rate of fuel injection is provided.
摘要翻译：公开了一种用于控制具有四部分凸轮轮廓的燃料喷射系统中的燃料喷射速率的凸轮。第一个120度是柱塞前进段。接下来的80度是先进的停留段。接下来的100°是柱塞回缩段，最后60°是缩回的停留段。柱塞前进段分为三个子部分：预注射冲程，注射冲程和超程冲程。预注射子段在注射开始时达到最小速度和加速度。在喷射子段中，凸轮从动件的加速度能够像赫兹应力允许的那样快速地实现，以增加喷射压力并达到最大喷射速率。超行程段实现了清晰的清洁注射结束。优选地，该凸轮在凸轮旋转的第一十个凸轮角度期间引起每冲程少于20mm 3的燃料喷射。在注射开始时注射压力和注射量减少，提前时间，并提供对燃料喷射速率的最佳控制。

摘要： In accordance with preferred embodiments of the invention a timing adjustment device includes a cam follower that is engaged between an overhead cam and an injector rocker arm, and is mounted on a rotatable eccentric shaft. The geometry of the eccentric shaft and cam follower is designed so that, as timing is varied by rotation of the eccentric shaft, no change is produced in the vertical height of the rocker arm when the cam shaft is on the outer base circle and the injector is bottomed, in order to assure that the "mechanical crush" of the PT type injector is constant despite changes in timing. In a first application of the timing arrangement, it is used together with a simple injector, which does not utilize a multi-plunger arrangement to form a hydraulic link, to achieve lower parasitic losses. To obtain independent control over injection pressure and timing, a fuel injector in which a hydraulic link is formed between plungers of a multi-plunger arrangement is used with the timing arrangement in order to allow the injection pressure to be maintained constant over a wide range of engine speeds without interfering with engine timing.
摘要翻译：根据本发明的优选实施例，定时调节装置包括凸轮从动件，其接合在顶置凸轮和喷射器摇臂之间，并安装在可旋转的偏心轴上。偏心轴和凸轮从动件的几何形状被设计成使得当定时通过偏心轴的旋转而变化时，当凸轮轴在外基圆上时，在摇臂的垂直高度上不产生变化，并且喷射器是为了确保PT型喷射器的“机械挤压”在时间上有变化时是恒定的。在定时装置的第一应用中，它与简单的喷射器一起使用，其不利用多柱塞装置来形成液压连杆，以实现更低的寄生损耗。为了获得对喷射压力和时间的独立控制，在定时装置中使用其中在多柱塞装置的柱塞之间形成液压连杆的燃料喷射器，以便允许喷射压力在宽范围内保持恒定发动机转速，而不会干扰发动机定时。

摘要： An improved fuel injector for providing precise control over injection timing, quantity and rate shape is provided which includes a fuel pressure balancing device for balancing the fuel pressure forces acting on a needle valve element while the element is in both the closed and open positions thereby permitting an actuator to more precisely and predictably control the movement of the needle valve element. The fuel pressure balancing device includes a cavity formed in the needle valve element and pressure balancing surfaces formed on the needle valve element and positioned in the cavity. The actuator may be a piezoelectric actuator for compressing actuating fluid in an actuating fluid circuit which includes a fluid chamber positioned adjacent a needle valve element and fluidically separate from a fuel supply circuit for supplying high pressure fuel for injection. Actuating fluid pressure in the chamber acts on the needle valve element to initiate injection. In another embodiment, the needle valve element is directly controlled by a solenoid actuator.

摘要： An electronically controlled fuel supply system is provided for employing a plurality of fuel injectors which maximize SAC pressures under both low speed and high speed operating conditions and are capable of sustaining SAC pressures in excess of 30,000 psi. The fuel supply system of the present invention includes a gear pump which supplies pressure-modulated fuel to a fueling channel and to a timing channel and from there to a plurality of injectors. Fuel pressure regulator means and timing fluid pressure regulator means are provided in the fueling and timing channel, respectively. An electronic control unit receives information relating to engine operating conditions from a plurality of sensors and actuates the fuel pressure regulator means and the timing fluid pressure regulator means to adjust the pressure as required for the specific engine operating conditions. The timing fluid is delivered to the injectors by the present system at a pressure sufficient to sustain a hydraulic link within the injector of the length necessary to maintain high SAC pressures during injection. Several embodiments of a fuel supply system which achieves these objectives are disclosed. A mounting integral with the cylinder head for an electronically controlled injector fuel supply system is also provided.

摘要： This disclosure deals with an aneroid for an internal combustion, compression-ignition engine including a turbocharger. The engine further includes a fuel supply system including a fuel supply rail connected to carry fuel to a plurality of fuel injectors and a regulator for regulating the pressure of the fuel in the supply rail. The quantity of fuel injected in each operating cycle of the engine is a function of the fuel pressure in the supply rail. The aneroid is connected in the rail between the regulator and the injectors, and it includes valve means operative to gradually increase the fuel pressure in the rail downstream of the aneroid, in response to a rise in manifold air pressure. The aneroid further includes means responsive to the downstream fuel pressure for adjusting the valve means to reduce the fuel pressure in response to a rise in the downstream fuel pressure.

摘要： The disclosure illustrates a fuel mileage indicator which gives a dynamic reading of the fuel mileage for a vehicle powered by an internal combustion engine. As a result it indicates to the driver whether he is driving efficiently and is conserving fuel. The device consists of a variable resistance device responsive to a fuel system parameter or other engine parameter which is proportional to engine fuel flow. This variable resistance device is connected in series with a generator having a D.C. voltage output directly proportional to vehicle speed. An ammeter indicates current through the circuit and is calibrated to give an output of miles per gallon.

摘要： A hydromechanical fuel pump system of supplying timing fluid and fuel to high pressure fuel injectors utilizing a hydromechanical fuel control circuit to control the flow of fuel that is withdrawn from a fuel reservoir by a pump and delivered to the fuel injectors which includes a speed signal generator that produces a fuel pressure in a speed signal branch line of the fuel control circuit that is a function of engine rpm, and a torque shaping module that is provided in a fuel delivery branch of the fuel control circuit. The torque shaping module controls the supply pressure of the fuel flow to the injectors so that, during an initial engine operating range, the supply pressure is merely that as received from the fuel pump, in a second engine operating range, the torque shaping module causes the supply pressure to be a function of fuel pressure in the speed signal branch line as boosted by an assist means, the effect of which is removed in a third engine operating range, and in a last engine operating range, the supply pressure is determined by partially offsetting the effect of the pressure in the speed signal branch line by a counterpressure factor.

摘要： A cam follower assembly for mechanically connecting a cam on a camshaft to a push rod assembly is disclosed. The cam follower assembly includes a cam follower link rotatably mounted to a pivot at a first end. At a second end the cam follower link has a substantially semicylindrical recess having a thin axial wall formed at each end of the recess. The cam follower link contacts a push rod adjacent its second end on a surface opposite the surface having the substantially semicylindrical recess. A pinless roller is mounted within the substantially semicylindrical recess and is restrained from axial movement by the thin axial walls. The pinless roller is held in rolling contact with a corresponding cam by imposition by the link of restraining force directly on the cam engaging surface of the roller. The roller may include an annular groove to facilitate lubrication of the cam follower assembly.
