Definitions
- the invention is based on a fuel distributor according to the claims 1 and 2.
- a fuel distributor for an internal combustion engine which serves to supply several fuel injectors with fuel, a number corresponding to the number of fuel injectors has continuous valve receptacles in a valve carrier, in which the electromagnetically actuated fuel injection valves can be inserted axially, and has a supply line open to the valve receptacles.
- the fuel injectors are fixed to the valve carrier with a contact strip which engages over the part of the injectors projecting from the valve receptacle and hooks into corresponding recesses in the valve carrier with locking lugs.
- the injection valves are fixed in the axial and circumferential directions by means of this contact strip, which also serves for the electrical contacting of the injection valves. Tolerance problems between the electrical plug pins on the injection valve and the electrical plug pin receptacles in the contact strip can, however, cause certain rotations of the injection valves during assembly, as a result of which the injection valves do not adhere to their predetermined orientation in the valve receptacles and their beam alignment is thus undesirably changed.
- the fuel distributor according to the invention with the characterizing features of claims 1 and 2 has the advantage that even in the first seconds after a hot start of the internal combustion engine, the formation of a sufficient reservoir with vapor-free fuel ensures that fuel-free fuel is sprayed off through the fuel injection valves is.
- the fuel-air mixture thus formed has good ignitability.
- valve receptacles In the case of a fuel distributor consisting of a single flow channel, good cooling is achieved by all-round flow around the valve receptacles and formation of vapor bubbles is avoided.
- the vapor bubble free fuel volume within the Valve receptacles must be protected from mixing with fuel permeated by vapor bubbles, which is achieved by arranging at least one fuel feed bore on a side of the valve receptacle that is not opposite to the flow direction, for example on a side of the valve receptacle that is perpendicular to the flow direction or away from the flow direction.
- the fuel distributor according to the invention with the characterizing features of claim 2 has the advantage that it can be produced in a simple and inexpensive manner and enables a large volume of fuel which is free of vapor bubbles. Furthermore, the fuel located in the outer annular gap is cooled by the fuel flowing through the fuel supply channel 2, thereby preventing the formation of vapor bubbles in the outer annular gap.
- FIG. 1 shows a section of a fuel distributor according to the invention in accordance with a first exemplary embodiment
- FIG. 2 shows a plan view of the fuel distributor
- FIG. 3 shows a section of a second exemplary embodiment of a fuel distributor according to the invention
- FIG. 4 shows a plan view of the fuel distributor and FIG Sheet metal part designed as a bayonet lock.
- the fuel distributors for fuel injection systems of mixture-compressing externally ignited internal combustion engines which are only shown as examples in the drawing, are designated by 1 and are connected to a fuel supply line, not shown in detail.
- a tubular fuel supply channel 2, for example having a rectangular cross section, of the fuel distributor 1 of FIGS. 1 and 2 with a flow cross section 16 is used to supply fuel to at least two fuel injector 3 to accommodate the fuel supply channel 2 along a longitudinal axis 6 of one of the number of fuel injectors 3 has a corresponding number of stepped valve receptacles 4 passing through the fuel supply channel 2, each with a valve receptacle opening 5, into which the fuel injection valves 3 can be inserted in such a way that the walls of the valve receptacles 4 the fuel injection valves 3 in the direction of a receiving longitudinal axis 7 at least partially surrounded with a radial distance.
- the fuel distributor 1 is e.g. so arranged on an intake manifold 8 of an internal combustion engine that the fuel injection valves 3 inserted into the fuel distributor 1 discharge the fuel into intake pipe ducts 9 of the intake manifold 8, for example immediately before intake valves of the internal combustion engine, not shown.
- the fuel distributor 1 is fastened, for example, to the intake manifold 8, for example by means of at least one stepped tubular screw receptacle 12 which penetrates the fuel supply channel 2 in two coaxial bores 74, 75 and is tightly inserted therein, for example by soldering or welding.
- the screw receptacle 12 has a first cylindrical section 77, on which is located a second cylindrical section 78 of smaller diameter is connected to the side facing the suction pipe 8.
- a radially outwardly extending shoulder 76 is formed, which is supported on the outside of the wall of the fuel supply channel 2 and fixes the axial position of the screw receptacle 12.
- a corresponding screw 14 is used, which cooperates with a thread 18, which is provided, for example, in the suction pipe 8.
- the fuel injection valves 3 shown in FIGS. 1, 2, 3 and 4 have at one connection end 10 an electrical connector 11 with e.g. two electrical contact elements 13 and, for example, two fuel supply openings 15 on their circumference.
- the fuel is dispensed from a spray opening 17 of the respective fuel injection valve 3 facing away from the connection end 10 when it is actuated.
- a known contacting plug (not shown) is used, for example, to electrically contact the fuel injection valves 3 at their electrical contact elements 13.
- each fuel injection valve 3 to the terminal end 10 is above the fuel supply apertures 15, facing a first annular groove 21 and facing • provided below the fuel supply ports 15 of the ejection opening 17 is a second annular groove 23rd
- a first sealing element 25, for example an O-ring is arranged in the first annular groove 21 and a second sealing element 27, for example an O-ring, is arranged in the second annular groove 23.
- the sealing elements 25, 27 produce a seal between the circumference of the fuel injection valve 3 and the wall of the valve receptacle 4, so that the fuel supplied to the fuel feed opening 15 of the fuel injection valve 3 is prevented from escaping from the valve receptacle 4 at an undesired location.
- a storage volume 47 surrounding the fuel injection valve 3 is formed, which extends in the direction of the longitudinal axis 7 of the first sealing ring 25 to the second sealing ring 27 and with which Flow cross section 16 of the fuel supply channel 2 of the fuel distributor 1 is connected via at least one fuel inlet opening 28.
- the storage volume 47 surrounding the fuel injection valve 3 is referred to below as a thick juice storage device 49.
- thick juice the expert describes the; fuel reduced by the more volatile components that have escaped as vapor bubbles. Since this thick juice fuel has a high boiling point, it is less prone to vapor bubble formation than normal consistency fuel. This is the only way to accurately measure the fuel tightly in liquid form during the hot start, since steam bubbles no longer influence the metering.
- the function of the thick juice store 49 is as follows: after switching off a hot-running internal combustion engine equipped with the fuel distributor 1 according to the invention, the surface of the fuel injection valve 3 and the fuel distributor 1 have a strong heat effect on those now motionless in the thick juice store 49 Fuel, since the cooling effect of the air flowing through the engine compartment, the cooling water circulated in the internal combustion engine and the fresh fuel flushing the fuel distributor 1 during operation are lacking. The result is heating of the fuel located in the thick juice store 49 and evaporation of the more volatile fuel components. This formation of vapor bubbles is gradually decreasing after the internal combustion engine has been switched off. Fuel pressure increased. Some time after the hot internal combustion engine has been switched off All more volatile fuel components evaporated within the thick juice store 49, the thick juice remains.
- this liquid thick juice is sprayed through the fuel injection valve 3 for the first seconds after the start. This ensures that the prepared fuel-air mixture is ready to ignite even during a hot start.
- a sensible transition from the injection of thick juice to the injection of cool, fresh fuel can be achieved by a suitable choice of the size of the thick juice store 49, that is to say by a choice of the size of the storage volume 47.
- the fuel inlet opening (s) 28 through which essentially only as much fuel can get into the thick juice reservoir 49 as the injection valve 3 is spraying.
- the fuel inlet opening 28 is not arranged on the side of the valve receptacle 4 facing the flow of the fuel shown by an arrow in the drawing, but on a side perpendicular to the flow direction or away from the flow direction, e.g. such that the normal vector of the fuel inlet opening is parallel to the direction of flow.
- valve receptacle 4 is manufactured particularly cost-effectively by deep drawing a sheet metal blank, while the fuel supply channel 2 is made from a tube with a rectangular cross section, for example, which is available as a commercially available semi-finished profile.
- the valve receptacles 4 each have a collar 51 which is open in the direction of the connection end 10 of the injection valve 3 and which consists of a radially extending part 53 and an adjoining cylindrical part 54.
- the radially extending part 53 of the collar 51 is adjoined in the direction of the spray opening 17 of the injector 3 used by a first cylindrical section 65, which has a second cylindrical section 66 with a smaller diameter than the first section 65 through a shoulder 67 is separated, which bears against the inside of the wall of the fuel supply channel 2 and fixes the valve receptacle 4 in its axial position.
- the valve receptacle 4 is in two coaxial bores 68, 69 whose diameters correspond to the outside diameters of the cylindrical sections 65, 66, inserted into the fuel supply channel 2 and tightly connected to it, for example by soldering or welding.
- the suction pipe 8 is sealed with a sealing element 73, for example a molded rubber part.
- FIG. 3 A second invention SLI exemplary embodiment is shown in Figure 3, and "4 of the drawings, the exemplary embodiment with respect to the game of Figure 1 and 2 have the same effect and consistent Bau ⁇ parts are designated by like reference numerals.
- the fuel supply channel 2 is surrounded by an outer tube 22, for example with a circular cross section, so that an annular section 31 is formed between the outer tube 22 and the fuel supply channel 2.
- the ring cross-section 31 is connected to the storage volume 47, which is limited by the circumference of the fuel injection valve 3 and the respective wall of the valve receptacles 4, for example by an opening 37 arranged in the outer tube 22 and at least one fuel inlet opening 28 of the valve receptacle 4 intersecting with the opening 37.
- beads 34 for example beads, which are located in the area of one end 41 of the fuel distributor 1 and extend radially over the circumference, for example beads, which are incorporated into the fuel supply duct 2 by inner rollers and have a larger diameter than the inner diameter of the outer tube 1 before assembly having the fuel supply channel 2 is held in its position in the outer tube 22 by a press fit and sealed for example by soldering.
- An opposite arrangement is also possible, in which the beads are arranged on the outer tube.
- the ring cross section 31 serves to form a fuel-free fuel reservoir.
- the flow cross section 16 is connected to the ring cross section 31 by at least one connecting opening 39 passing through the wall of the fuel supply channel 2.
- the main stream of the fuel flushing the fuel distributor 1 flushes the flow cross section 16 for cooling the fuel injection valves 3 and the fuel distributor 1 and flows past the ring cross section 31 only separately through the wall of the fuel supply channel 2. Only a small part of the fuel flowing through the flow cross section 16 passes through the at least one connecting opening 39 into the ring cross section 31 and replaces the fuel discharged therefrom by the fuel injection valves 3.
- the connection opening 39 can be in the middle, but also in another place of the fuel supply channel 2.
- connection openings 44 are provided in the area at both ends 41 of the fuel supply channel, which make a connection between the ring cross section 31 and the flow cross section 16 and serve to vent the ring cross section 31 serving as a fuel reservoir.
- the ventilation openings 44 not only can a fuel change be made between the flow cross section 16 and the ring cross section 31, but steam bubbles can also pass from the ring cross section 31 into the flow cross section 16.
- the ring cross section 31 serving as the fuel reservoir and the individual storage volumes 47 surrounding the respective fuel injection valve 3 together form the thick juice reservoir 49, in which the hot internal combustion engine equipped with the fuel distributor 1 according to the invention is steam-free, ie liquid fuel can accumulate and enables a trouble-free hot start of the internal combustion engine.
- the fuel reservoir of the thick juice volume 49 formed by the ring section 31 is cooled particularly well by the fuel flushing through the flow section 16 of the fuel distributor 1 owing to the large surface area of the fuel supply channel 2 separating the flow section 15 and the ring section 31.
- connection of the injection valves 3 to the valve receptacle 4 is established either by a bayonet connection or a clamp connection.
- the flange 50 and the collar 51 are surrounded by a clamp 52 with a U-shaped profile.
- the distance between the two legs 79, 80 of the clamp 52 pointing in the direction of the receiving longitudinal axis 7 is dimensioned such that one leg 79 rests on the flange 50 of the injection valve 3, while the other leg 80 bears against the radially extending part 53 of the collar 51 abuts, whereby the flange 50 and thus the injection valve 3 firmly in the collar 51 of the valve aufnähme 4 clamped and fixed in its axial and rotational position.
- the circumference of the clamp 52 can be adjusted using a screw 81.
- the circumference of the clamp 52 is enlarged such that it can be guided over the collar 51 of the valve receptacle 4.
- the circumference of the clamp 52 is reduced by turning the screw 81 until it lies firmly against the collar 51 and the flange 50.
- the fuel injector 3 has an end flange 63 designed as a bayonet latch 57, which consists of two diametrically opposed locking tabs 56 which can be inserted axially into the annular space 62 through two cutouts 59.
- the bayonet catch 57 together with the bayonet lock 55 forms a bayonet catch 58.
- the two recesses 59 are adjoined in the circumferential direction by two overlapping sections 60 which, after the bayonet bolt 57 inserted with its locking tabs 56 into the recesses 59, overlap the locking tabs 56.
- overlapping sections 60 At the end of the overlapping sections 60 there is in each case a stop 61 for the locking tabs 56.
- the stops 61 fix the rotational position of the fuel injection valve 3 in the valve receptacle 4 and thus the injection direction of the fuel injection valve 3 and are made from the corresponding sections by bending radially extending part 82 right to this manufactured in the direction facing away from the connection end 10.
- the width of the locking tabs 56 measured in the circumferential direction of the locking tabs 56 is dimensioned with regard to the position of the stops 61 so that when the locking tabs 56 abut the stops 61, the locking tabs 56 are completely covered by the overlapping sections 60.
- the use of the easily producible fuel distributor 1 according to the invention in an internal combustion engine enables the injection of vapor-free fuel in the first seconds after a hot start of the internal combustion engine by the formation of a fuel reservoir with vapor-free fuel, whereby the hot-start properties are significantly improved.
- the fixation of the fuel injection valve 3 to the fuel distributor 1 by means of a bayonet closure 58 enables a quick and secure installation.
