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.
- Fuel injection system for direct injection of fuel into a combustion chamber of an internal combustion engine 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 pivotably mounted on the first designed as an O-ring seal member so that it is slightly tilted within predetermined limits by a solid angle OC.
- 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 installation allows the individual high-pressure injection valves and a FCAs and on the other hand ensures accurate positioning of the valve.
- a fixing element which fixes the nozzle body in its position in the first recess, and which is formed in the form of a thickening with spherical contour.
- the fixing element has outwardly curved end surfaces and / or plane end surfaces.
- the cylinder head has a corresponding second recess, in which the fixing element can be inserted, in the form of a slot.
- the fixing element may preferably z.
- Example be provided as a molded pin on the outer periphery of the valve housing, which then engages in the bore or recess in the cylinder head (or in the rail) and thus fixes the fuel injection valve securely in position.
- the longitudinal axis of the fixing element is provided substantially coaxially with the longitudinal axis of the fuel injection valve.
- the convex contour of the fixing element has an undercut above the convex contour, so that a tilting of this Vermosfix ist in the form of the fixing and thus breaking it is prevented. It is also particularly advantageous if the Vermosfix ist in the form of the fixing below the convex contour downwards, ie in the direction of the discharge end of the fuel injection valve, tapers to provide a so-called insertion bevel to facilitate the mounting of the high-pressure injection valve.
- the fuel injector 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.
- the boundary of the recess can be designed, for example, with a radius or as an edge. Contours are also possible that can already be produced with the cast of the cylinder head.

- the nozzle body 11 has a sealing ring 12 plugged onto a discharge-side end.
- the fuel injection system shown here is an example at which the fuel injection valve 1 is not mounted with an intermediate sleeve to the fuel rail 4, but only a Dichtré between
- Fuel distribution line 4 and fuel injection valve 1 in the form of an O-ring 5 are. Furthermore, this injects

- a fixing element 15 extends on the discharge side from a connection region 28 between the plug 7 and the valve housing 13.
- the fixing element 15 is in the form of a second recess or receiving bore 31 in the form of a fixing element
- a longitudinal axis 29 of the fixing element 15 extends coaxially to the longitudinal axis 16 of the nozzle body 11.
- a thickening in the form of four outwardly projecting members 30 is provided, which have a spherical contour.
- the number of outwardly projecting members 30 is variable.
- the fixing element 15 is injection-molded, for example, as part of a plastic encapsulation.
- the housing 13 is provided with a plastic extrusion, which simultaneously forms the plug 7, on whose outer periphery an outwardly projecting fixing element 15 is formed, which forms a convex contour and as Verwoodfix ist of Valve in the cylinder head (not shown) is used.
- a rib 17 is also provided along the longitudinal axis 29 on the outer circumference of the fixing element 15, which is molded onto the fixing element 15.
- the fixing element 15 or its convex contour and the radially outwardly of the fixing element 15 outwardly projecting elements 30 which form the thickening are formed such that at its upper inlet end an undercut 19 is provided and they leash in the discharge direction of the fuel injection valve
- Insertion bevel 18 in the form of a continuous taper, which the assembly of the fuel injection valve. 1 facilitated.
- the undercut 19 at the upper end of the convex contour also prevents that after tilting 15 in the cylinder head bore or recess (not shown) tilted.
- 3a to 3d show respective sectional views along the line III-III of FIG. 2 of various embodiments of the Verwoodfixticianen invention or the fixing element 15th
- Fig. 3a shows a VerFDfix ist having four outwardly projecting members 30, which are provided in each case at 90 ° intervals on the outer periphery of the fixing element 15 and thus form four spherical contours and the thickening of this.
- Fig. 3b shows an embodiment which also has four outwardly projecting elements 30, of which, however, each two opposing elements differ in the length with which they protrude from the fixing element 15 radially outward.
- the outwardly projecting end surfaces 20 of the fixing elements 15 are here in contrast to the embodiment shown in Fig. 3a plan formed, but may also have a curvature, so that a convex contour is provided.
- Fig. 3c shows an embodiment in which only two outwardly projecting elements 30 are provided and the remaining outer surfaces of the fixing element 15, on which no outwardly projecting elements 30 are provided, may be of any desired design.
- Fig. 3d shows an embodiment which is similar to that shown in Fig. 3a, but in addition to the outer periphery of the fixing member 15, a reinforcement in the form of a transverse rib 17 is provided.
- Fig. 4 is schematically the deviation of the longitudinal axis 29 of the
- the Vermosfix ist of the fuel injection valve 1 in the form of the fixing element 15 with spherical contour engages in the recess 31 a.
- the rotational fixation in the recess 31 also inclines with a corresponding tolerance compensation.
- the Vermosfix ist or the fixing element 15 could tilt in the recess 31 and break under certain circumstances.
- 5a to 5d show various side views of a portion of the fixing element 15 which has various embodiments of Vercardonne Heidelberg or outwardly projecting members 30 at its outer periphery.

- Fig. 6b shows a second recess 31, in which the
- Verformfix ist (not shown) of the fixing member 15 engages, which is designed as a slot. It is particularly advantageous that the necessary assembly clearance between the cylinder head bore or recess 31 is independent of the deflection between the rail cup 21 and cylinder head bore 31.
