摘要： A fuel system for an engine including a cylinder, a cylinder head having a quill tube bore, and at least, one fuel injector, is provided. The fuel system comprises a common rail, a quill tube, and a connector. The quill tube is configured to connect the common rail to the at least one fuel injector to supply fuel from the common rail, wherein the quill tube is coupled to the cylinder head such that a portion of the quill tube is positioned inside the quill tube bore in the cylinder head defining a coolant jacket therebetween. The connector is configured to couple the quill tube to the cylinder head, and to hold the quill tube inside the quill tube bore. The connector includes at least one through hole configured to allow passage of the coolant to the coolant jacket.

摘要： A fuel injector for a common rail fuel system includes an energizer section, an injector section, and control section axially disposed along an injector axis. To control and injection event, the control section includes a control orifice manifold that has a plurality of control orifices and control passages to distribute high pressure fuel with the injector assembly. To prevent plugging of the control orifices and passages, an internal filter element with a plurality of filtration orifices is located in proximity to the control orifice manifold.

摘要： A nozzle for a fuel injector is disclosed. The nozzle may have an internal axial nozzle bore. The nozzle may also have at least one orifice passing from the nozzle bore radially outward through a wall of the nozzle at a tip end. Further, the nozzle may have a sac volume formed in the tip end and defined by a bore radius and a tip radius. The bore radius may be generally perpendicular to the central bore. The tip radius may be generally parallel to the central bore. The tip radius may be less than the bore radius.

摘要： A fuel injector includes an injector body forming an actuator portion. An actuator bore is formed in the actuator portion and is at least partially defined by an inner surface and by an end surface. An actuator disposed in the actuator bore and has an outer surface such that a flow channel can be defined between the inner surface of the actuator bore and the outer surface of the actuator. A cooling flow passage is formed in the injector body, in fluid communication with the actuator bore, and is adapted to supply cooling fluid to the actuator bore. A drain passage is formed in the injector body, in fluid communication with the actuator bore. An internal cooling fluid flow path extends from the cooling flow passage, through the flow channel, and from the flow channel through the drain passage.
