Abstract: 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.

Abstract: A leak prevention device including an expandable chamber and control valve for preventing fuel leakage into the combustion chambers of a internal combustion engine equipped with a common rail fule injection system including open nozzle injectors and a shut off valve mounted in the common rail upstream of the fuel injectors to isolate, when closed, the fuel injectors from the source of fuel under pressure. The expandable chamber contains a variable volume held in its collapsed condition during engine operation and expanded upon engine shutdown sufficiently to prevent the flow of fuel from any injector into the corresponding combustion chamber.

Abstract: 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.

Abstract: A fuel system for fuel injectors of an internal combustion engine is provided with a hydromechanical timing valve having a valve body assembly with a barrel and plunger arrangement. The plunger is displaceable within the barrel under the counterbalancing forces of rail fuel pressure (load) and one or more timing valve springs. The relative position of the barrel and plunger determines the effective size of the port through which timing fluid can flow. In accordance a first embodiment, the plunger has a tapered head which covers and uncovers ports in the barrel to a greater or lesser extent, thereby creating a variable flow-through cross section. Alternatively, in accordance with other embodiments, the barrel has ports with slot-like orifices of progressively changing widths which coact with a metering groove on the spool to define a variable flow cross section through which the timing fluid must pass.

Abstract: An electro-hydraulic position-servo device to quickly and accurately position a stop element is provided for use with a positive displacement fuel injection system, wherein a shuttle is used to positively displace pre-metered slugs of fuel to unit injectors. The stop device is operatively associated with a control shaft having at least one helical surface thereon; the stop element and control shaft slidably located within a housing. The housing permits communication between at least one pressurized fluid source and a drain line by way of a chamber within which the control shaft is located. Thus, by simply rotating the control shaft from rotational drive means, the control shaft will assume an axial position determined by the orientation of the helical surface with respect to the supply and drain lines. The device is adjustable by rotation of the shaft to a new position with the re-orientation of the helical surface.

Abstract: A fuel injection system is provided for a multicylinder internal combustion engine. Each cylinder is provided with at least one fuel injector. The system includes a cam-operated pumping plunger which maintains fluid pressure within an accumulator and controls the intermittent application of fluid pressure from the accumulator through a first chamber in which the plunger moves to one end of a metering plunger. The opposite end of the metering plunger coacts with a second chamber in which the metering plunger moves to define a cavity into which fuel is supplied for subsequent feeding to the cylinder injector. Fuel enters the cavity during those periods when the metering plunger is not subjected to the accumulator fluid pressure, the latter being under the control of the pumping plunger. The pumping plunger reciprocates within its chamber and is rotatable about its longitudinal axis. An elongated groove is formed in and encompasses the exterior of the pumping plunger.
