摘要： An exhaust valve system for an internal combustion engine including a turbocharger is provided for effectively increasing the turbocharged boost pressure at low load engine conditions thereby effectively improving engine transient response. The exhaust valve system includes an exhaust valve control device operable in a normal timing mode for permitting normal opening of one or more exhaust valves at a normal opening crank angle, and in an advanced timing mode for advancing the timing of the opening of the exhaust valve to an advanced opening crank angle prior to the normal opening crank angle while maintaining the timing of normal closing of the exhaust valves at a normal closing crank angle. In one embodiment, the exhaust valve control device includes a tappet and an actuating fluid supply which operate to move the tappet between expanded and collapsed states to advance the opening of the exhaust valve while permitting normal exhaust valve lift to be introduced prior to peak exhaust valve lift thereby maintaining the normal peak lift and the normal timing of exhaust valve closure. In a second embodiment, the exhaust valve control device includes a dedicated advanced timing mode rocker lever capable of selectively actuating one of a pair of exhaust valves to create an early opening exhaust event prior to a normal exhaust event.

摘要： Fuel injection rate shaping is integrated into the pressure intensification stage of a hydraulically actuated fuel injector having a pressure intensifier. In a first embodiment, the pressure intensification plunger is formed of two parts creating a damping chamber therebetween from which fluid is forced out through orifices in a lower one of the plunger parts during an initial phase of displacement of the upper part. Thus, injection will be performed initially at a lower pressure and rate, which increases once the plunger parts make contact. In a second embodiment, a throttled flow is set via a restrictor housing that telescopingly receives the upper plunger part, so that a lower injection rate occurs while fluid is bled off through a restricted flow path between the restrictor housing and the upper plunger part, and a higher injection rate is produced once a port in the upper plunger clears the restrictor housing. In a third embodiment, the two plunger parts of the intensifier have different areas relative to each other. In a fourth embodiment, flow to the intensifier plunger is varied by the intensifier plunger co-acting with a shaped inlet port increasing the effective area of the inlet port through which flow enters the intensifier as the intensifier plunger is displaced during its injection stroke. In a fifth embodiment, a throttling effect produced by a clearance between a protrusion on the intensifier plunger and a receiving bore in the intensifier body is used reduce the intensification effect during the initial phase of injection.

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： A fuel injector is provided with a lower nozzle body which is cooled with a small amount of metered fuel. In one embodiment, a blind passage is formed to extend from the upper portion to the lower end of the injector nozzle valve element. A transverse passage is formed in the nozzle valve element connecting the blind passage and the nozzle bore. Rail pressure causes a metered amount of fuel to flow through the nozzle bore, the transverse passage and upwardly along the blind passage to the drain passage. Inward cooling occurs by providing more surface area over which the fuel flows. In another embodiment, a sleeve is formed to fit over an existing nozzle to form a passage surrounding the injector tip. An orifice is located in the nozzle housing to connect the nozzle cavity with the annular passage thereby providing a small amount of fuel to drain.

摘要： A novel and improved motion sensor for high pressure fluid delivery devices is provided which effectively senses movement of a component in a high pressure environment while minimizing the likelihood of fluid leakage through a receiving cavity containing at least a portion of the sensor. The motion sensor includes a sealing surface shaped and positioned relative to a force resisting surface formed on an annular cavity surface of the receiving cavity so as to apply a fluid, e.g. fuel, pressure induced sealing force against the force resisting surface due to the high pressure fluid forces acting on the sensor body. The sealing surface may be conically shaped for contacting a complementary conically shaped force resisting surface and/or the sealing surface may extend perpendicular to the direction of the fluid forces acting on the sensor body for abutment against a complementary positioned annular land containing the force resisting surface.

摘要： Check valves (500) are incorporated into a fuel injector so as to form a controlling orifice in the system between the solenoid vales which direct fuel to the respective injection and timing chambers of the fuel injector and the chambers themselves. The precision fuel metering capability of the valve (500) is determined by an annular clearance created between the plunger (512) of the valve and the valve body (510) when the valve is in its maximum stroke. For achieving a bi-stable operation of the valve, the ratio of the plunger valve seat (510d) area to the maximum plunger valve (512b) area and the spring (514) are key parameters. The check valves (500) are formed as cartridge type check valves that can be calibrated outside of the injector prior to the installation thereof.

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 improved high pressure fuel injector for internal combustion engines of the type having a plunger assembly, with a plurality of plungers, that is mounted within a central bore within the body of the fuel injector for reciprocal movement, the plunger assembly having an upper plunger and a lower plunger mounted for reciprocal motion within the central bore and a variable volume injection chamber in said lower end of the central bore between the injection orifice and a bottom end of the lower plunger. In accordance with a preferred embodiment, the problem of large quantities of air being drawn into the injector from the combustion chamber during the retraction stroke injection stroke is avoided by limiting the return stroke of the lower plunger to a distance that is significantly less than that of the stroke of the upper plunger of the plunger assembly. Furthermore, a cushioned stopping of the return movement of the lower plunger is obtained and the injector is also able to allow different maximum injectable charge capabilities to be produced from the same basic set of components without requiring more than the return spring assembly and injector nozzle to be changed.

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.
