Definitions

  • the invention relates to a fuel injection valve according to the preamble of claim 1 and of a fuel injection system according to the preamble of claim 12.
  • known solutions for fixing a high-pressure injection valve in a cylinder head include providing a rib at a portion of the outer circumference of the valve body which is inserted into the cylinder head, which then engages in a correspondingly provided in the cylinder head groove.
  • the groove must be milled in accordance with the cylinder head.
  • no insertion bevels can be attached, which facilitate insertion of the valve when installed in the cylinder head.
  • Another solution for positionally fixing a high-pressure injection valve in a cylinder head provides the known use of a hold-down, which then passes the position to the rail and the cylinder head.
  • a fuel injection system for direct injection of fuel into a combustion chamber of an internal combustion engine is described, wherein a cylinder head for each fuel injection valve has a opening into the associated combustion chamber receiving bore for receiving the Abspritzabitess of the fuel injection valve.
  • the receiving bore is formed there as a stepped bore and has a tapered portion on which a first sealing element sealingly abuts and the Abspritzabites seals against the cylinder head.
  • the fuel injection valve is pivotally mounted on the first designed as an O-ring sealing member so that it is within a predetermined limits by a solid angle ⁇ slightly pivoted.
  • the fuel injection valve according to the invention with the characterizing feature of claim 1 and the fuel injection system according to the invention with the characterizing feature of independent claim 12 have the advantage that a cost-effective solution for fixing the fuel injection valve in a cylinder head is made possible on the one hand sufficient insertion bevels for a problem-free assembly allows the individual high-pressure injection valves and a FCAs and on the other hand ensures accurate positioning of the valve.

  • the fuel injection valve is not mounted by default with an intermediate sleeve to the rail, which acts as a compensation element, the provision of the slot or the one-sided open slot in the cylinder head is particularly advantageous.
  • the high-pressure injection valve must be slightly inclined. This inclination causes a movement in the Verwarfix ist. Therefore, it is important that there is sufficient space in the radial direction, so that the radial movement of the valve by the tolerance compensation does not lead to a transverse force (strain) on the Vermosfix réelle or on the fixing.
  • the fuel injection valve is a multi-hole valve with asymmetrically arranged spray holes and that the sprayed through the injection holes fuel jet is inclined relative to the valve longitudinal axis.
  • the bore or recess, in which engages the VerFfix ist or at least one fixing element is designed as a one-sided open slot. This is particularly advantageous in tight spaces, because in this embodiment can be advantageously dispensed with the insertion.
