Definitions
- the invention relates to an internal combustion engine having a cylinder head with a combustion chamber side fire deck, with at least one releasably connected to the cylinder head Injektorhülse for receiving an injector, wherein the injector is screwed to a fire deck side first end via a first screw to the fire deck, and wherein the injector in Area of the first end has at least one radially projecting first support area with a fire deck facing the first support surface which rests on a formed by the cylinder head first mating surface.
- JP 11-132100 A describes a cylinder head structure having a combustion chamber side fire deck and a top deck spaced from the firebox, wherein a central injector sleeve for receiving an injection device is provided per cylinder.
- the injector is screwed via a first screw on the upper deck and a second screw with the fire deck of the cylinder head.
- an attachment for an injector sleeve of a cylinder head is known from JP 2002-188547, wherein the injector sleeve is screwed into the cylinder head in the area of the fire deck.
- the object of the invention is to avoid these disadvantages and to increase the rigidity of the cylinder head with low material cost.
- a tight connection with a long service life between injector and cylinder head is to be created.
- the distance between the first mating surface and the second mating surface of the cylinder head is greater than the distance between the first bearing surface and the second bearing surface of the injector, so in the screwed state, the injector and the first screw is under a tensile prestress caused by a prestressing tensile force.
- the first screw is designed to exert the bias tension on the built-in cylinder head injector.
- An external thread of the injector can be part of the first screw. In a simple embodiment with few components, it is provided that the external thread of the injector sleeve is screwed into a threaded bore of the fire deck.
- the external thread of the injector is screwed to a support on a bearing surface of the fire deck nut, which is arranged from the side of the combustion chamber in a bore of the fire deck.
- the external thread of the injector is screwed to a support on a bearing surface of the fire deck nut, which is arranged from the side of the combustion chamber in a bore of the fire deck.
- this variant can be dispensed with preparation of a thread in the Injektorbohrung the cylinder head, which are reduced by the first screw tensions occurring in the fire deck.
- the injector when the injector is screwed in the region of the second end via a preferably formed by a hollow screw element by a second screw with the cylinder head, said second support surface of the second screw Injector sleeve is pressed against the second mating surface of the cylinder head.
- the element can act with an injector sleeve facing the pressure surface on an engagement surface of the injector in the region of the second end.
- the second screw prevents lifting of the injector by the gas forces in the cylinder chamber.
- the first bearing surface may be glued to the first mating surface and / or the second bearing surface may be glued to the second mating surface.
- the deflection of the fire deck and the resulting stresses can be reduced by the ignition pressure without requiring higher material use in the cylinder head.
- FIG. 1 shows an injector sleeve for an internal combustion engine according to the invention in a meridian section in a first embodiment
- Fig. 2 is an injector in a partial section in a second embodiment.
- the Fig. lund Fig. 2 each show an injector sleeve 2 arranged in a cylinder head 1 for receiving an injection device opening into a combustion chamber 3 of an internal combustion engine and not shown further.
- Reference numeral 28 denotes the cavity within the injector sleeve 2 for receiving the injector.
- the injector sleeve 2 is releasably secured via a first screw 4 in an adjacent to the combustion chamber 3 fire deck 7 of the cylinder head 1, and has a first end 5 in the region of the fire deck 7 and the first end 5 facing away from the second end 6. In the region of the first end 5, the injector sleeve 2 has an external thread 16, which cooperates with a corresponding internal thread 8 for fastening in the cylinder head 1.
- the internal thread 8 is formed by a threaded bore 17 of the fire deck 7 of the cylinder head 1.
- Fig. 2 shows an embodiment in which the internal thread 8 is replaced by a nut 19. is formed, which is supported on shoulders 20, 21 of the fire deck 7. The nut 19 is arranged from the side of the combustion chamber 3 in the bore 22 of the fire deck 7.
- At least one radially projecting first support region 9 is arranged with a first support surface 10 facing the fire deck 7, which rests on a first counter surface 11 formed by the cylinder head 1.
- the injector sleeve 2 has at least one radially outwardly projecting second support region 12 with a second support surface 13 facing the fire deck 7.
- the second bearing surface 13 rests on a second counter surface 14 formed by the cylinder head 1.
- first contact surface 10 and the first counter surface 11 are formed as planar annular surfaces normal to the axis 2a of the injector sleeve 2.
- First bearing surface 10 and first counter surface 11 may also be formed as a corresponding conical surfaces. The same applies to the second bearing surface 13 and the second counter surface 14th
- the injector 2 In the relaxed state, in which all bearing surfaces 10; 13 and mating surfaces 11; 14 not touch, so if for example the injector 2 is not screwed into the cylinder head 1, the distance a between the first mating surface 11 and the second mating surface 14 of the cylinder head 1 is greater than the distance b between the first support surface 10 and the second As a result, in the screwed-in state, the injector sleeve 2 is under a tensile prestress caused by a prestressing tensile force, the first screwed connection 4 being designed to exert the pretensioning tensile force on the injector sleeve 2 installed in the cylinder head 1.
- the biasing force must be chosen at least so large that a lifting of the injector 2 is avoided by the resulting during combustion in the combustion chamber 3 maximum cylinder pressure.
- an element can be screwed by a second screw 15 in the region of the second end 6 of the injector 2 with the cylinder head 1, which - in addition to the biasing tension - the second bearing surface 13 presses against the second counter surface 14.
- the im in 1 shown by a hollow screw 24 formed element acts with one of the injector sleeve 3 facing the pressure surface 23 on an oppositely directed engagement surface 24 of the injector 2 in the region of the second end 6 a.
- the second screw 15 has in in FIG. 1 shown an external thread 26 on the hollow screw 25, which in an internal thread 27 of the cylinder head 1 is screwed.
- first bearing surface 10 is bonded to the first mating surface 11 and / or the second bearing surface 13 with the second mating surface 14 by means of an adhesive.
- the deflection of the fire deck 7 and the resulting stresses can be reduced by the ignition pressure without higher material use in the cylinder head 1 would be required. This allows a very rigid construction of the cylinder head 1 and low weight.
