Definitions

  • the invention relates to a connecting element for fuel injection systems for connecting a fuel injection valve with a fuel-carrying component and a fuel injection system with such a connecting element. Specifically, the invention relates to the field of fuel injection systems for mixture-compression, spark-ignition internal combustion engines.
  • a spring clip which has the function of a connecting element for connecting a fuel injection valve with the cup of a fuel rail.
  • holes facing away from one another on the housing of the fuel injection valve must be provided on an outer side of the fuel injection valve. In these holes ends of the spring clips are hung, so that thereby pivoting of the spring clip about a given by the two holes on the housing of the fuel injection valve pivot axis is possible.
  • cavities facing away from the cup must be provided on the outside of the cup.
  • a connector for fuel injection systems for connecting a fuel injection valve with a cup of a fuel component leading.
  • the connecting element has a first holding arm and a second holding arm, which serve indirectly via upstanding tabs for engaging in two provided on an outer side of the cup recesses of the cup.
  • a contact part is provided with a first leg portion and a second leg portion, wherein the first leg portion of the contact part and the second leg portion of the contact part lie in a plane which is oriented parallel to a plane in which the first support arm and the second support arm lie. Plants for the fuel injector are provided on the first leg portion and on the second leg portion.
  • the connecting element alone surrounds the fuel injection valve, wherein the connecting element insofar clings the fuel injection valve completely below the cup.
  • a further upstanding tab portion is provided on the connecting element on the opposite side of the connector of the fuel injection valve side, which also engages in a recess on the collar on the outside of the cup. All of these securing elements are used exclusively for fixing the position and rotation of the fuel injection valve relative to the cup, with the first holding arm and the second holding arm of the connecting element springing against the collar of the cup only from below.
  • the fuel injection system according to the invention with the features of claim 1 has the advantage that an improved design of the individual components and optionally an improved mode of operation are possible. Specifically, the junction between the fuel injector and the connector can be simplified, and the holding force that keeps the fuel injector on the cup of the fuel-bearing component in operation can be adjusted independently of the mounting requirements.
  • the fuel injection system is suitable for gasoline direct injection.
  • the connecting element is particularly suitable for fuel injection systems that are used for gasoline direct injection.
  • the fuel-carrying component is in this case preferably designed as a fuel distributor, in particular as a fuel distributor strip.
  • a fuel distributor can on the one hand serve to distribute the fuel to a plurality of fuel injection valves, in particular high-pressure injection valves.
  • the fuel distributor can serve as a common fuel storage for the fuel injection valves.
  • the fuel injection valves are then preferably connected via corresponding connecting elements with the cups of the fuel distributor. During operation, the fuel injection valves then inject the fuel required for the combustion process under high pressure into the respective combustion space.
  • the fuel is in this case compressed via a high-pressure pump and quantity-controlled conveyed via a high-pressure line in the fuel distributor.
  • valve plug a conspicuous and disturbing contribution to the overall noise of the engine can be made, which can be described as a valve plug.
  • a valve leakage is caused by the rapid opening and closing of the fuel injection valve, in which the valve needle is adjusted with high dynamics in the respective end stops.
  • the impact of the valve needle in the end stops leads to short-term, but very high contact forces, which can be transmitted via a housing of the fuel injection valve to the cylinder head and the fuel-carrying component, if there is a direct contact. This then leads to the cylinder head or to the fuel component leading to a strong noise.
  • an effective decoupling on the one hand to the cylinder head and on the other hand to the fuel-carrying component can be realized in a compact design and thus with a small footprint in an advantageous manner. Furthermore, it is possible to save a separate hold-down, which for example uses a spring force, or to design it with a reduced spring force.
  • the fuel injection valve By mounting the fuel injection valve to the cup of the fuel-carrying component by means of the connecting element, the fuel injection valve can be positioned so that the fuel injection valve is not in direct contact with the cylinder head.
  • the required seal between the fuel injection valve and the cylinder head can be chosen independently of the suspension.
  • a Teflon seal can be provided between the fuel injection valve, in particular a nozzle body or a valve tip, and the cylinder head.
  • there are great constructive freedom with respect to the seal between the fuel injection valve and the cup of the fuel component leading Thus, the cheapest for the particular application form of the seal can be realized here. In operation, due to the pressure of the fuel supplied, a force acts on the fuel injector in the direction of the cylinder head.
  • the connecting element can be designed largely independently of the requirements of the assembly in an advantageous manner so that the required holding force can be applied by the connecting element, without the fuel injection valve is adjusted too far from the predetermined mounting position.
  • the connecting element can be laterally pushed onto the cup and the fuel injection valve, if the fuel injector is positioned in the mounting position on the cup.
  • the choice of material and the geometric configuration, which also influence the rigidity can be adapted to the holding force to be applied during operation.
  • first leg portion of the support member and the second leg portion of the support member are interconnected by a connecting portion of the support member.
  • the stability of the connecting element, in particular of the support part of the connecting element is improved.
  • this can be used to maintain the relative position of the first leg portion and the second leg portion to each other in an improved manner, for example, when in operation due to the fuel pressure high forces are introduced from the fuel injection valve at the support points (abutment points) of the leg portions in the connecting element.
  • a spreading of the leg portions can be avoided.
  • operational movements of the fuel injection valve can be reduced.
  • connection portion of the support member in the plane in which the first leg portion of the support member and the second leg portion of the support member lie.
  • first leg portion of the support member and the second leg portion of the support member from the connecting portion spread apart with an acute angle therebetween.
  • through the connecting portion can be a load-related change of this acute angle be avoided.
  • the length, in particular arc length, of the connecting portion can be kept very short by this configuration, which further improves the stability.
  • first leg portion of the support member and the second leg portion of the support member are oriented parallel to each other.
  • this may possibly facilitate the assembly.
  • larger tolerances can be specified.
  • the leg portions of the support member oriented parallel to one another may also be spread slightly apart when pushed onto the fuel injection valve, so that trapping of the fuel injection valve between the two leg sections or a fixation is made possible.
  • the connecting portion of the support member is designed as a curved connecting portion, in particular circular arc-shaped connecting portion.
  • an advantageous load is enabled during operation. This results in a high stability of the connecting element. In addition, this results in a good manufacturability.

  • a stop line at the circular arc-shaped connecting portion of the support member may be predetermined.

  • the connecting element can be pushed onto the cup and the fuel injection valve until the end position relative to the cup is reached.
  • This can also be an optional predetermined target positioning of the support member with respect to the fuel injection valve can be achieved, which is easy to control.
  • the contact part has an arc section, in particular a circular arc section, which in the mounted state bears against an outer side of the cup.
