Definitions

  • the invention also relates to a fuel injector for injecting a gaseous and / or liquid fuel into a combustion chamber of an internal combustion engine having such a nozzle assembly.
  • fuel injectors are also known as dual fuel injectors or dual fuel injectors.
  • a dual fuel injector is known that is capable of selectively injecting two different fuels, such as diesel and liquefied natural gas.
  • the two-fuel injector comprises a first and a second valve needle.
  • the first valve needle on the lifting movement of the first injection holes are releasable and closable, is guided in the second valve needle liftable.
  • the second valve needle is designed for this purpose as a hollow needle.
  • About the second valve needle more spray holes are releasable or closed. All spray holes are formed in a nozzle body which surrounds the valve needles and at the same time forms a sealing seat for the two valve needles.
  • a fuel separator in the form of a sleeve is provided between the two valve needles, which is biased in the axial direction against the nozzle body. Furthermore, the injector has a hydraulic locking arrangement which is intended to counteract mixing. A minimal mixing takes place nevertheless.
  • the present invention has for its object to provide a nozzle assembly for a fuel injection valve for injecting a gaseous and / or a liquid fuel, in which all the beam-forming geometries are optimally matched or tuned. Furthermore, the nozzle assembly is to ensure a secure media separation.
  • the nozzle assembly is proposed with the features of claim 1. Advantageous developments of the invention can be found in the dependent claims. Further, a fuel injection valve is provided with such a nozzle assembly.
  • the nozzle assembly proposed for a fuel injection valve for injecting a gaseous and / or liquid fuel into a combustion chamber of an internal combustion engine comprises a needle-shaped first injection valve member which is designed to release and close at least one injection hole through which the liquid fuel can be injected in an at least partially hollow needle second injection valve member is guided in a liftable manner, wherein the second injection valve member has the outer peripheral side a sealing contour which cooperates with a sealing seat which is formed in a nozzle body surrounding the second injection valve member at least partially.
  • the nozzle body has a central opening, through which an end portion of the second injection valve member, in which the at least one injection hole is formed, is guided.
  • the guided through the opening of the nozzle body end portion of the second injection valve member may be formed in such a manner that it closes or limits the opening. If the opening is merely limited by the end section of the second injection valve member, a free opening cross section remains between the injection valve member and the nozzle body, via which the gaseous fuel can be injected. This means that the gaseous fuel does not necessarily have to be introduced via an injection hole into the combustion chamber of the internal combustion engine. However, if the opening is permanently closed by the end portion of the second injection valve member, at least one further injection hole for injecting the gaseous fuel is provided. This is then also formed in the end portion of the second injection valve member.
  • the guided through the central opening of the nozzle body end portion of the second injection valve member preferably forms a kind of cap, so that the at least partially formed as a hollow needle second injection valve member front, d. H. on the combustion chamber side, is closed.
  • the cap-like end of the second injection valve member assists effective media separation.
  • the end section of the second injection valve member preferably has a flow-guiding outer contour which extends over at least a partial circumferential area and which is arranged downstream of the sealing contour in the flow direction of the gaseous fuel.
  • the gaseous fuel is supplied via the formed in the nozzle body sealing seat of the flow-guiding outer contour of the injection valve member and deflected accordingly.
  • the gas stream can be deflected, for example, in the direction of an opening cross-section remaining between the injection valve member and the nozzle body or in the direction of at least one injection hole, so that the opening cross-section or injection hole are optimally flown.
  • the gaseous fuel is injected via a free opening cross-section between the injection valve member and the nozzle body, can also be taken on the design of the outer contour influence on the spray pattern.
  • the spray angle can be specified via the flow-directing outer contour.
  • the end section of the second injection valve member preferably forms a fuel collecting space, into which the at least one injection hole for introducing the liquid fuel opens.
  • the fuel plenum promotes uniform delivery of the liquid fuel into the combustion chamber. This is especially true if the fuel collecting space by a circumferential groove or a circumferential channel is trained.
  • the cross section of the groove or of the channel can be constant over the circumference or change.
  • the fuel collecting space is preferably arranged in the region of the flow-guiding outer contour of the end section of the second injection valve member. Accordingly, liquid and gaseous fuel accumulate in the fuel collecting space, but with a time offset from one another, since the two injection valve members are preferably opened in succession.
  • the flow-directing outer contour can therefore also be used for the flow guidance of the liquid fuel.
  • the fuel collecting space is connected directly to the combustion chamber.
  • the fuel collection chamber opens to the combustion chamber.
  • the fuel collecting space may be formed as a circumferential or at least over a partial circumferential region of the second injection valve member extending groove. It can also be provided several such grooves, which are preferably arranged at the same angular distance from each other.
  • the fuel collecting space is connected only indirectly via at least one further injection hole with the combustion chamber.
  • the further injection hole then serves to inject the gaseous and the liquid fuel.
  • the further injection hole is arranged coaxially with respect to the first injection hole, through which the liquid fuel passes into the fuel collecting space. The coaxial arrangement simplifies the production of the injection holes.
  • the specific embodiment of the end portion of the second injection valve member may therefore be decisive for the spray pattern of the gaseous and the liquid fuel. This is especially true when the fuel plenum is directly connected to the combustion chamber of the internal combustion engine.
  • a control edge is formed on the nozzle body, preferably in the region of the fuel collecting space formed in the second injection valve member. This causes the free opening cross section between the second injection valve member and the nozzle body in dependence changed from the stroke of the second injection valve member.
  • rate shaping and a variation of the penetration depth can be represented in a simple manner.
  • a sealing seat for the first injection valve member is formed in the end portion of the second injection valve member. This is preferably conically shaped, so that the first injection valve member automatically undergoes a centering.
  • the sealing seat formed in the nozzle body for the second injection valve member is also conically shaped. In this way, an automatic centering of the second injection valve member with respect to the nozzle body can be achieved.
  • the in the FIGS. 1a and 1b illustrated nozzle assembly comprises a nozzle body 7, which surrounds a first and a second injection valve member 2, 4 at least in sections.
  • the first injection valve member 2 is designed needle-shaped and received in a liftable manner in the second injection valve member 4.
  • the second injection valve member 4 is at least partially as a hollow needle for receiving the first injection valve member 2 executed.
  • the liquid fuel is passed through an annular space 14 remaining between the first and second injection valve members 2, 4.
  • the gaseous fuel is passed through an annular space 15 remaining between the second injection valve member 4 and the nozzle body 7.
  • the second injection valve member 4 has a cap-like end portion 9, which is guided through a central opening 8 of the nozzle body 7, so that the cap-like end portion 9 closes the opening 8.
  • a spray hole 3 is formed, via which the liquid fuel can be discharged.
  • the injection hole 3 is preceded by a sealing seat 13 for the first injection valve member 2, which is formed by a conically shaped inner peripheral surface of the second injection valve member 4.
  • the injection hole 3 opens into a fuel collection chamber 11, which is formed as a circumferential channel in the end portion 9 of the second injection valve member 4.
  • the fuel collection chamber 11 is in turn indirectly connected via at least one further injection hole 12 with a combustion chamber 1 of an internal combustion engine.
  • the liquid fuel is thus injected via the spray hole 3, the fuel collection chamber 11 and the injection hole 12 into the combustion chamber 1.
  • the injection holes 3 and 12 are arranged coaxially thereto.
  • the fuel collecting space 11 opens via a flow-directing outer contour 10 in the direction of a sealing seat 6, which is formed in the nozzle body 7 for the second injection valve member 4.
  • the flow-guiding outer contour 10 is adjoined by a sealing contour 5, which interacts with the sealing seat 6. If the second injection valve member 4 opens, gaseous fuel flows via the sealing seat 6 into the fuel collecting space 11.
  • the gas flow is supplied to the injection hole 12 via the flow-directing outer contour 10, which extends into the fuel collecting space 11.
  • the gaseous fuel is finally injected into the combustion chamber 1 of the internal combustion engine (see Fig. 1b ).
  • FIGS. 2a and 2b is a modification of a nozzle assembly according to the invention can be seen.
  • This eliminates the at least one additional injection hole 12, the Combustion fuel chamber 11 connects with the combustion chamber 1. Instead, the connection is made via a free opening cross-section remaining between the second injection valve member 4 and the nozzle body 7 in the region of the central opening 8 formed in the nozzle body 7.
  • the fuel collection chamber 11 is designed as a circumferential groove which opens toward the combustion chamber 1.
  • a control edge 16 is also formed, which is arranged at the level of the fuel collecting space 11, so that the free opening cross section changes depending on the stroke of the second injection valve member 4. This means that the gas mass flow varies depending on the stroke. Because with progressive stroke of the second injection valve member 4, the remaining between the injection valve member 4 and the nozzle body 7 remaining free opening cross-section decreases.
  • FIGS. 1 and 2 Nozzle assemblies shown represent only two preferred embodiments of the invention. Further modifications are possible, which relate in particular to the design of the end portion 8 of the second injection valve member 4.
