  • Patent number: 10487787
    Abstract: An injector tip for a fuel injector includes an exterior surface, and an interior surface defining a sac region therein. The injector tip is also configured to define at least one orifice radially extending from the interior surface to the exterior surface. The orifice is disposed in communication with the sac region located adjacent to the interior surface. Further, the injector tip also includes a mound that is defined on the interior surface such that the mound is integrally formed with the interior surface adjacent to the sac region. The mound is configured to extend along an axis of the sac region and terminate prior to a perimeter of the at least one orifice.

  • Publication number: 20190170103
    Abstract: A fuel injector includes a nozzle including at least one outer orifice. The at least one outer orifice selectively injects a first fuel. An outer check is disposed movably within the nozzle. The outer check includes at least one first orifice and at least one second orifice. The at least one first orifice and the at least one second orifice are disposed circumferentially spaced apart with respect to one another. Each of the at least one first orifice and the at least one second orifice selectively injects a second fuel. An inner check is disposed movably and concentrically within the outer check. The at least one outer orifice is adapted to selectively injects at least one of the first fuel and the second fuel therethrough based on a position of each of the outer check and the inner check.

  • Publication number: 20190145339
    Abstract: A fuel injector includes a nozzle having at least one first orifice provided therein. The at least one first orifice is adapted to selectively inject one of a fuel and an oxidant. An outer check is disposed movably within the nozzle. The outer check includes at least one second orifice provided therein. The at least one second orifice is adapted to selectively inject an other of the oxidant and the fuel. An inner check is disposed movably and concentrically within the outer chock. The at least one second orifice is adapted to align with respect to the at least one first orifice to selectively inject the fuel and the oxidant together through the at least one first orifice based on a position of each of the outer check and the inner check.

  • Publication number: 20190063391
    Abstract: A fuel injector assembly for an engine. The engine includes a cylinder head defining a through-hole. The fuel injector assembly includes an insert, having a first end and a second end, configured to be received within the through-hole and coupled to the cylinder head. The insert defines a bore extending from the first end to the second end. The fuel injector assembly further includes a fuel injector including a plurality of orifices, received within the bore of the insert; and a duct structure including a plurality of ducts, coupled to the insert such that the plurality of ducts align with the plurality of orifices to at least partially receive one or more fuel jets from the plurality of orifices of the fuel injector.

  • Patent number: 10012196
    Abstract: A duct structure for a fuel injector assembly of an engine includes a first ring structure, a plurality of ducts, a plurality of posts, and an engagement structure. The fuel injector assembly includes a fuel injector having a plurality of orifices to discharge fuel. The first ring structure is configured to be coupled to a cylinder head of the engine, and defines a central axis. The ducts are circularly arrayed around the central axis, and are configured to provide passages to the fuel discharged from the fuel injector. The posts connect the ducts to the first ring structure. Further, the engagement structure is configured to engage with the fuel injector to align the ducts with the orifices such that each of the plurality of ducts is configured to receive fuel discharged from a corresponding one of the plurality of orifices.
