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 dual fuel engine powers a machine by burning natural gas and liquid diesel fuel. When operating in a low load mode, some of the engine cylinders are fueled with a high ratio of diesel/gas, and the remaining cylinders are unfueled. When operating in a high load mode, all of the engine cylinders are fueled with a low ratio of diesel/gas. When operating in a limp home mode, the fuel injectors are configured to inject only diesel fuel into all of the plurality of engine cylinders.

摘要： A fuel system includes a plurality of fuel injectors each defining a nozzle supply passage, a nozzle outlet, a low pressure space, and a drain. The fuel system includes a plurality of mechanically actuated pressure intensifiers each including a tappet and being positioned partially within one of the fuel injectors, and a common rail fluidly connecting with each of the fuel injectors. Each of the fuel injectors further includes an injection pressure control mechanism having an injection pressure control valve. Each injection pressure control valve blocks the corresponding pressure intensifier from the common rail and fluidly connects the pressure intensifier with the low pressure space at a first position, and fluidly connects the pressure intensifier with the common rail and blocks the pressure intensifier from the low pressure space at a second position. Each of the fuel injectors further includes a pressure recovery mechanism having a pressure recovery valve. Each pressure recovery valve blocks the corresponding pressure intensifier from the common rail and fluidly connects the low pressure space and the drain at the first position, and fluidly connects the low pressure space with the common rail and blocks the low pressure space from the drain at the second position. Injecting fuel via operating the fuel system may include operating the fuel system in a low leakage mode where the pressure intensifier displaces fuel at a low pressure, between high pressure injections.

摘要： An electrically controlled fuel injector includes an armature that is movable between a first armature position and a second armature position inside an armature cavity containing fuel. By reducing the size of the armature cavity to a squish film drag gap, the armature experiences a squish film drag phenomenon when the armature moves from the first armature position to the second armature position reducing the armature travel speed but also reducing the settling time of the armature after an injection event. By reducing the armature travel speed; the armature experiences a reduction in magnitude of armature bounce allowing the armature to settle down quicker and produce minimum controllable injection events with shorter dwell times than predecessor fuel injectors, especially for close coupled post injection events.

摘要： A fuel injector includes an injector body having an internal surface and an external surface. A tappet assembly includes a non-guided tappet and a plunger assembly, and is mounted on the injector body. The tappet assembly is movable with respect to the injector body a displacement distance between an advanced position and an extended position. A portion of the plunger assembly is slidably guided along the internal surface of the injector body, while the non-guided tappet is free of contact with both the internal surface and the external surface of the injector body in the advanced and extended positions. The tappet assembly may be prevented from moving beyond the extended position using a snap ring positioned within a retention opening of the fuel injector body.

摘要： An electronically controlled fuel injector includes a reduced part count and complexity over similar fuel injectors without a substantial reduction in performance capabilities. This is accomplished by using a one-piece needle that is hydraulically balanced and biased toward a closed position with a spring positioned in the needle control chamber. Although subtle, this injector has some ability to control the fuel pressure when the needle valve is opening and closing by adjusting a relative timing of a pressure control valve opening relative to a needle control chamber, using separate electrical actuators. The disclosure is particularly applicable to fuel injectors that cycle through high and low pressure states during and between injection events, respectively. Cam actuated fuel injectors being particularly well suited.

摘要： A mechanically actuated electronically controlled unit injector includes an electronically controlled spill valve to precisely control timing of fuel pressurization within a fuel pressurization chamber. Cavitation bubbles may be generated in the region of the valve seat when the spill valve member is closed to raise fuel pressure in the fuel injector. This cavitation can cause erosion on the spill valve member and the surrounding injector body. In order to preempt cavitation damage, the valve member may be modified to include a compound annulus that includes a small annulus that corresponds to an identified cavitation damage pattern. Although the generation of cavitation bubbles may continue after such a strategy, cavitation erosion, and the associated liberation of metallic particles into the fuel system can be reduced, and maybe eliminated, by the preemptive cavitation reduction strategy.
