Definitions
- the present invention relates to an injection device for a diesel engine the preamble of claim 1.
- Newer injection systems for diesel fuel which improve efficiency of the diesel engine and a reduction in fuel consumption are designed so that the ideal characteristic curve via an electronic control for the time of injection depending on the respective operating conditions Ignition pressure and fuel consumption can be optimized.
- statically compressed fuel in the line system also contributes to this at, through which the flow losses in the distribution of diesel fuel be reduced.
- the operating pressures are around 1,600 bar compared to around 900 bar at until then the usual injection system.
- the Fuel distributor made from a forging to the connection nipple Attachment of pressure lines are formed.
- the distribution routes are created by drilling, i.e. it is a longitudinal bore introduced into the cross bores through the connecting nipples.
- Another disadvantage of the known fuel rail is that it is a relative has high weight.
- the invention is therefore based on the object of developing an injection device, which is simple and inexpensive to manufacture, the lowest possible weight exhibits and meets the high stress requirements.
- This design of the fuel rail allows one manufactured according to the prior art many times cheaper Manufacturing, essentially, with the exception of insertion holes for the connecting nipple is possible through non-cutting processing.
- connection nipples by welding or soldering is also an opposite the forging and drilling of the known tube much easier Manufacturing process.
- the largely non-cutting processing, especially the now possible waiver of one Drilling the longitudinal hole by drilling also has a particularly favorable one Effect on the strength of the pipe.
- the strength of the pipe is further increased by machining the surface.
- the tube can be widened and kneaded, creating a optimal weight design of the fuel rail results.
- one Ball calibration is possible, with a work hardening and smoothing of the inner wall he follows.
- the mechanical processing introduction of the Insert holes
- resulting notch effect and rounded edges achieves what in the transition area of the insertion holes with the inner wall also results in a reduction in the notch effect.
- Fuel distributors can choose smaller wall thicknesses that lead to a significant weight reduction compared to the known tube.
- the connecting nipples which are advantageously designed as turned parts, are in the insertion holes of the pressure accumulator are pressed in and then welded or soldered.
- Induction welding has proven to be a particularly advantageous welding process shown. However, it is also conceivable to use this type of welding or a capacitor discharge welding, which has only a limited heat affected zone in the Distribution pipe has, so that its material properties remain practically unchanged.
- tempered steels such as C 45 or alloyed steels are advantageous.
- a rust-resistant steel is also suitable DIN 17455 advantageous.
- An AgCu solder is used when soldering the connecting nipples to the fuel rail and soldered at a process temperature of around 750 ° C.
- An injection device is shown in the figures, which has a fuel distributor 1 has, which consists of a drawn or rolled tube.
- the interior of the fuel distributor 1 forms a pressure accumulator 2 in the through holes 10 open, each connected to a pressure line 5.
- the through holes go 10 to the outside of the fuel distributor 1 in a receiving funnel 7 above, which widens outwards.
- connection nipple 3 press screws 4 are screwed through each Pressure line 5 is guided, which has a compression head 6 at the end.
- the diameter of the through hole 10 corresponds approximately to the clear diameter the pressure line 5, so that practically this directly into the pressure accumulator 2 flows.
- the pressure screw 4 has on the fuel rail 1 opposite end of a cuff with a key surface, such as this can be clearly seen in FIG. 1.
- connection nipple 3 is with provided with an external thread onto which a union nut 9 is screwed.
- an end face of the distributor pipe 1 is included closed a sealing piece 12 which on its side facing the pressure accumulator 2 Side is crowned and in a correspondingly adapted recess of the fuel rail 1.
- the press nipple 13 is included provided with an internal thread 14.
- the connecting nipple 3 is pressed into the fuel rail 1, wherein the connecting nipple 3 has a cylindrical shaft which of a Press ring 18 is enclosed, by means of which the connecting nipple 3 in the wall of the fuel rail is pressed.
- the connecting nipple 3 provided with a through hole 16 which opens into the pressure accumulator 2 and on the opposite side has a receiving funnel 17, in which the Compression head of the pressure line 5 is pressed in a sealing manner.
- connection nipple 3 with a conical shaft is provided, which is also surrounded by a press ring 19 through which the connecting nipple 3 in a correspondingly adapted bore of the fuel rail 1 is pressed.
- the taper of the shaft of the connecting nipple 3 extends starting from the pressure accumulator to the pressure line 5.
- connection nipple 3 in this embodiment is connected by a rivet 20 to the fuel rail 1, for example can be introduced in the form of a blind rivet.
- connection nipple has 3 a conical shaft with a corresponding press ring is enclosed.
- connection nipple shown in Figure 8 is designed so that it is transverse extends through the fuel rail 1.
- the through hole 16 opens into one transverse to it, that is to say in the axial direction of the pressure accumulator 2 Cross hole 22.
- connection nipple 3 or the pressure lines 5 on the fuel rail 1 are shown in FIGS. 11 and 12.
- a spring clip 26 can be seen, the compression head of the pressure line 5 engages and is supported on the opposite side of the fuel rail 1 and presses the pressure line 5 onto the fuel rail 1 by the spring force.
- FIG Ring 27 which has an elongated hole extending over a partial circumference 28, through which the pressure line 5 is guided and the underside of which Compression head 6 supports.
- This underside is eccentrically shaped so that it can be turned accordingly of the ring 27, the pressure line 5 is pressed against the fuel rail 1.
- FIGS. 9 and 10 show possibilities for the axial sealing of the pressure accumulator 2 shown.
- FIG. 9 there is a ball 23 with a corresponding one Pressed excessively into the pipe end of the fuel rail 1, whereby a molded seat 21 caused by the oversize of the sealing ball 23 is formed, which results in a sealing surface in the area of the sealing ball jacket.
- the sealing ball 23 can by caulking the wall of the fuel distributor 1 in the system area with the Sealing ball 23 or be set by other suitable measures so that a tight seal of the pressure accumulator 2 also taking into account the therein prevailing high pressures is guaranteed.
- sealing ball 23 which is preferably a greater hardness than that Has material of the fuel rail 1 by a threaded plug 25 against the circumferential approach 24 pressed so that it is due to the deformation gives an annular sealing surface.
