摘要： A fuel injection valve has first injection holes, second injection holes, a first needle that opens and closes the first injection holes, and a second needle. The fuel injection valve is arranged such that a part of fuel injected from the first injection hole and a part of fuel injected from the second injection hole are gathered together at a position spaced from the side wall of the cavity by a predetermined distance. The second needle starts operating to open the second injection holes, after a predetermined time elapses from a point in time at which the first needle starts operating to open the first injection holes.

摘要： A method of operating an engine system should produce relatively low concentrations of various emissions without compromising a desired power output of the system. In order to operate an engine system of the present disclosure, a predetermined total amount of fuel injected into at least one combustion chamber is apportioned into at least a first amount and a second amount of fuel. The first amount of fuel is injected into the at least one combustion chamber during non-auto ignition conditions. The second amount of fuel is injected into the at least one combustion chamber during auto-ignition conditions. When the engine system is in a mid-low engine load range, the second amount of fuel is one of equal to or less than 15% of the predetermined total amount of fuel. When the engine system is in a high engine load range, the second amount of fuel is greater than 15% of the predetermined total amount of fuel.

摘要： A system for injecting fuel into the combustion chamber of a self-igniting internal combustion engine, has a control unit which acts upon a spring-controlled injection device which includes a nozzle needle, by way of which one or more injection openings are opened or closed. The control unit includes a first valve and a second valve, which each include one pressure chamber which communicate with one another via a pressure line. The first valve and the second valve are connected in series, and the first valve controls the subjection of the pressure chamber of the second valve to pressure, and the level of the injection pressure during the injection phases is controlled by the second valve.

摘要： Fluid in a chamber, through which a fuel control armature is moving, is used to dampen armature vibrations. This dampening effect is achieved by forming a passage through which the fluid flows as the actuator moves to a steady state position. This passage may be implemented in a control module for controlling fuel delivery in a fuel injector. The control module includes a control module housing defining the cavity. The armature is disposed at least partially within the cavity. The armature affects the flow of fuel in the injector by changing the area of a fuel port through which fuel passes. The fluid passage is formed as the armature moves towards a contact wall defining the cavity.

摘要： A common rail intensifier fuel injection system includes a plurality of fuel injectors respectively associated with cylinders of an internal combustion engine. A common rail supplies fuel at an intensified pressure to the fuel injectors and receives the fuel at the intensified pressure, alternately, from at least two fuel pressure intensifying circuits. At least one of the fuel pressure intensifying circuits includes a fuel pressure intensifier having an operating chamber for receiving and discharging an operating fluid, and a fuel chamber of a diameter smaller than that of the operating chamber for receiving fuel at a low pressure from the fuel supply and discharging the fuel at the intensified pressure into one of the fuel pressure intensifying circuits. A control valve, in a first position, connects the operating fluid source with the operating chamber of the fuel pressure intensifier and, in a second position, connects the operating chamber of the fuel pressure intensifier with a drain. A controller switches the control valve between the first and second positions and switches the supply of fuel at the intensified pressure, to the common rail, between the various fuel pressure intensifying circuits.

摘要： Inclusion of a direct control needle valve in fuel injectors can allow for independent control of injection pressure and timing. Engineers have learned that it is desirable to position the control valve assembly in close proximity to the needle valve member to improve response time. However, by placing the control valve assembly in a central portion of the fuel injector, at least one fluid passage must often be routed through the electrical actuator included in the valve assembly. The present invention seeks to address this problem by providing a direct control valve assembly for a fuel injector that directs fluid around the electrical actuator without increasing the size of the fuel injector. Thus, the present invention includes an electrical actuator having an actuator centerline that is oriented at an angle, which is preferably perpendicular, with respect to a centerline of the fuel injector.

摘要： A fuel injector comprising a valve needle slidable within a first bore, a surface associated with the valve needle being exposed to the fuel pressure within a first control chamber and movement of the valve needle away from the valve needle seating being limited by a moveable stop member. The stop member has a surface exposed to fuel pressure within a second control chamber. The fuel injector also includes a control valve arrangement for controlling the fuel pressure within the first and second control chambers to control movement of the valve needle and the stop member. The invention also relates to a fuel injector in which the control valve arrangement is arranged to permit the rate of valve needle movement away from the valve needle seating to be varied, in use.
