Definitions

  • the invention is based on a fuel distributor according to the preamble of claim 1. It is already known from DE-A-3326408, which is considered to be the closest prior art, that such a fuel distributor for an internal combustion engine is known, which is used for supplying fuel to several so-called Feed type of trained fuel injectors is used, has a number of continuous valve receiving openings, in which the fuel injectors can be used, corresponding to the number of fuel injectors, and has a flow cross-section that is open to the valve receiving openings and that through a partition wall into an inflow cross section that serves as a fuel supply line, and one Return flow cross section is divided.
  • the entire main fuel flow supplied to the fuel distributor flows through the inflow cross section which is directly connected to the valve receiving openings, while the fuel not sprayed off by the fuel injection valves reaches the return flow cross section.
  • the formation of fuel vapor bubbles in the fuel injection valve can then lead to starting difficulties of the internal combustion engine if fuel containing vapor bubbles is sprayed off in the first seconds after the start.
  • the cause of the starting difficulties is the strong emaciation and thus the unwillingness to ignite the fuel-air mixture formed.
  • These vapor bubbles also form when the freshly conveyed cool fuel flowing in via the fuel distributor when starting from the inflow cross section directly into the Fuel injector arrives because the hottest area is directly around the valve seat and at the latest there the more volatile fuel components turn into steam.
  • a fuel distributor (DE-A-38 43 097) for fuel injectors in a top-feed design, in which two metal pipes running at a radial distance are arranged in the longitudinal direction of the fuel supply line, which are connected to an electrical voltage and for measuring the Alcohol concentration in the fuel.
  • the tubes are provided with radial openings so that a subset of the main fuel flow flowing through the interior of the inner tube radially passes through the two tubes and into an annular space surrounding the outer tube, which is connected to the nozzle of the top feed fuel injection valves is.
  • the amount of fuel present in the annulus is also flushed very quickly downstream from the nozzle of the fuel injectors into the fuel supply line during a hot start, and freshly delivered fuel reaches the fuel injectors, the evaporates and leads to starting difficulties.
  • the fuel distributor according to the invention with the features of claim 1 has the advantage that even in the first seconds after the hot start of the internal combustion engine, the spraying of vapor-free fuel by the fuel injection valves is ensured by the formation of a sufficient reservoir with vapor-free fuel.
  • the fuel-air mixture thus formed has good ignitability.
  • the second channel serves to increase the volume surrounding the fuel injection valves so that when the hot internal combustion engine is switched off, a sufficient amount of vapor-free, i.e. liquid fuel can accumulate, which enables the internal combustion engine to start hot and ensures the fuel supply until the fuel injection valves are sufficiently cooled down that no vapor bubbles form in the fresh fuel which reaches the fuel injection valves from the first channel.
  • the fuel distributor with the fuel supply line divided by a partition into a first channel and a second channel can be produced in a simple and inexpensive manner.
  • the storage volume surrounding the fuel injection valves is formed between the wall of the valve receiving openings and the circumference of the respective fuel injection valve.
  • a tube is arranged in the fuel supply line, which forms the partition between the first channel and the second channel.
  • the outer diameter of the tube is smaller than the diameter of the inner wall of the fuel supply line.
  • Such a partition wall formed by the tube has a very large surface area, so that the fuel located in the second channel is cooled particularly well by the fuel flowing past in the first channel.
  • FIG. 1 shows a fuel distributor according to the invention according to a first embodiment
  • FIG. 2 shows a section along the line II-II in FIG. 1
  • FIG. 3 shows a fuel distributor according to the invention according to a second embodiment
  • FIG. 4 shows an enlarged section of the fuel distributor shown in FIG Figure 5 shows a fuel distributor according to the invention according to a third embodiment.
  • the fuel distributors for fuel injection systems of mixed-compression spark-ignition internal combustion engines are designated by 1.
  • the fuel distributor 1, which has, for example, an elongated shape, is used to supply fuel to at least two, in the first exemplary embodiment shown in FIGS. 1 and 2, for example, four fuel injection valves 3.
  • the fuel distributor 1 along a longitudinal distribution axis 6 has a number of stepped valve receiving openings 5, corresponding to the number of fuel injection valves 3, through which the fuel injection valves 3 can be inserted so that the walls of the valve receiving openings 5 the fuel injection valves 3 in the direction of a receiving longitudinal axis 7 at least partially surround each valve receiving opening 5.
  • the fuel distributor 1 is e.g. so arranged on an intake manifold 8 of an internal combustion engine that the fuel injectors 3 used in the fuel distributor 1 discharge the fuel into intake manifold channels 9 of the intake manifold 8, for example immediately before intake valves, not shown, of the internal combustion engine.
  • the fuel injection valves 3 shown for example in Figures 1, 3 and 5 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 valve end 17 of the respective fuel injector facing away from the connection end 10 when it is actuated.
  • a known contacting strip 19, shown in dashed lines in FIGS. 1, 3 and 5, is used, for example, for the electrical contacting of the fuel injection valves 3 on their electrical contact elements 13.
  • each fuel injection valve 3 On the circumference of each fuel injection valve 3, above the fuel supply openings 15, which are formed at least approximately at the same axial height of the receiving longitudinal axis 7, face the connection end 10, a first annular groove 21 and below the fuel supply openings 15 face the valve end 17, a second annular groove 23 intended.
  • a first sealing ring 25 is arranged in the first annular groove 21 and a second sealing ring 27 is arranged in the second annular groove 23.
  • the sealing rings 25, 27 provide a seal between the circumference of the fuel injection valve 3 and the wall of the valve receiving opening 5, so that the fuel to be supplied to the fuel supply openings 15 of the fuel injection valve 3 is prevented from escaping from the valve receiving opening 5 at an undesired location.
  • a fuel supply line 29 running in the longitudinal direction of the fuel distributor parallel to the longitudinal axis 6 of the distributor is formed, which serves to supply fuel to the fuel injection valves 3, for example has a circular cross section and is connected to the valve receiving openings 5.
  • a pipe 31 is arranged in the fuel supply line 29, the circumference of which has approximately the same diameter as the inner one Wall of the fuel supply line 29.
  • the assembly of the tube 31 into the fuel supply line 29 can be done, for example, by pressing in the tube 31 having a slightly larger diameter than the inner wall of the fuel line 29, so that a firm hold of the tube 31 in the fuel supply line 29 is ensured.
  • the circumference of the tube 31 in the first exemplary embodiment lies partially against the wall of the fuel supply line 29.
  • the fuel supply line 29 is divided into a first channel 33 and a second channel 35.
  • the first channel 33 is through the inner wall of the tube 31 and the second channel 35 through part of the outer wall of the tube 31, which is designed as a partition 37 and is deformed such that the partition 37, for example, parallel to the longitudinal axes 7 of the valve receiving openings 5th runs and limits the inner wall of the fuel supply line 29 facing the valve receiving openings 5.
  • the second channel 35 is tangentially connected to the individual valve receiving openings 5 by means of overlapping openings 38.
  • the first dividing wall 37 of the fuel supply line 29 extends somewhat beyond the valve receiving openings 5 in the direction of the longitudinal distribution axis 6.
  • the second channel 35 of the fuel supply line 29 is used to form a fuel reservoir.
  • the first channel 33 is connected to the second channel 35 through at least one through opening 39 passing through the partition wall 37.
  • the main stream of the fuel flushing the fuel distributor 1 flushes the first channel 33 for cooling the fuel injection valves 3 and the fuel distributor 1 and flows past the second channel 35 only separately through the partition wall 37. Only a small part of the fuel flowing through the first channel 33 reaches the second channel 35 through, for example, a through opening 39 and replaces the fuel discharged from this reservoir by the fuel injection valves 3.
  • the passage opening 39 can be in the middle, but also at a different location of the partition 37.
  • a ventilation opening passing through the partition wall 37 44 and 45 are provided, which establish a connection between the second channel 35 and the first channel 33 and serve to vent the second channel 35 serving as a fuel reservoir. Not only can fuel change between the first channel 33 and the second channel 35 take place via the ventilation openings 44 and 45, but vapor bubbles can also pass from the second channel 35 into the first channel 33.
  • a storage volume 47 is formed which surrounds the fuel injection valve 3 and extends in the direction of the receiving longitudinal axis 7 from the first sealing ring 25 to the second sealing ring 27 and with the second channel 35 and with the fuel supply openings 15 of the respective fuel injection valve 3 is connected.
  • the second channel 35 of the fuel supply line 29 forming the fuel reservoir and the storage volume 47 surrounding each fuel injection valve 3 form a large volume which is present in the area of the fuel injection valves 3 and is referred to below as the thick juice store 49.
  • the person skilled in the art describes "thick juice" as the fuel which is reduced by the more volatile constituents which have escaped as vapor bubbles. Since this thick juice fuel has a high boiling point, it is less prone to vapor bubble formation than fuel of normal consistency. This is the only way to allow an exact metering of the amount of fuel during a hot start in liquid form, since steam bubbles can no longer influence metering.
  • the function of the thick juice accumulator 49 is as follows: after switching off a hot-running internal combustion engine equipped with the fuel distributor 1 according to the invention, there occurs one on the surface of the fuel injection valve 3 and of the fuel distributor 1 strong heat effect on the fuel which is now motionless in the thick juice store 49, since the cooling effect of the air flowing through the engine compartment, the cooling water circulated in the internal combustion engine and the fuel distributor 1 flushing during operation and partially flowing into the fuel reservoir formed by the second channel 35 There is no fuel. The result is heating of the fuel located in the thick juice store 49 and evaporation of the more volatile fuel components. This vapor bubble formation is further intensified by the fuel pressure in the first channel 33, which drops slowly after the internal combustion engine is switched off, and thus also in the thick juice reservoir 49.
  • the vapor bubbles collect on the partition 37 and at the latest at the next start of the internal combustion engine via the ventilation openings 44, 45 and the passage opening 39 from the second channel 35 of the fuel distributor line 29 into the first channel 33.
  • FIGS. 3 and 4 A second exemplary embodiment according to the invention is shown in FIGS. 3 and 4, FIG. 4 showing a greatly enlarged section of the fuel distributor 1 shown in FIG. 3.
  • the same and equivalent parts are identified by the same reference numerals as in FIGS. 1 and 2.
  • a fuel supply line 29 running in the longitudinal direction of the fuel distributor and parallel to the longitudinal axis 6 of the distributor which serves to supply fuel to the fuel injection valves 3, e.g. has a circular cross section and is connected to the valve receiving openings 5 by means of the overlapping openings 38.
  • a tube 31 is arranged, which extends, for example, concentrically to the inner wall of the fuel supply line 29 and whose outer diameter is smaller than the diameter of the inner wall of the fuel supply line 29. This means that between the circumference of the tube 31 and the inner wall An annular gap 55 is formed in the fuel supply line 29.
  • the wall of the tube 31 serving as the partition 37 divides the fuel supply line 29 into the first channel 33 inside the tube 31 enclosed by the wall of the tube 31 and into the second channel 35 formed by the annular gap 55 outside the tube 31, both in parallel run to the distribution longitudinal axis 6.
  • the tube 31 is arranged eccentrically in the fuel supply line 29.
  • the second channel 35 is tangentially connected to the individual valve receiving openings 5 and to the storage volume 47 delimited in the radial direction by the circumference of the fuel injection valve 3 and the respective wall of the valve receiving opening 5.
  • the second channel 35 serves to form a fuel reservoir.
  • the wall of the tube 31 acting as a partition 37 between the two channels 33, 35 passes through at least one, for example circular or slit-shaped, passage opening 39 which connects the first channel 33 to the second channel 35.
  • the main stream of the fuel flushing the fuel distributor 1 flushes the first channel 33 for cooling the fuel injection valves 3 and the fuel distributor 1 and flows past the second channel 35 only separately through the partition wall 37. Only a small portion, which corresponds to the amount of fuel sprayed through the fuel injection valves 3, of the fuel flowing through the first channel 33 passes through, for example, a passage opening 39 into the second channel 35 and in this way replaces the fuel dispensed from this fuel reservoir.
  • the second channel 35 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, which is steam-free, that is to say liquid fuel, can accumulate and one enables trouble-free hot start of the internal combustion engine.
  • the annular fuel reservoir of the thick juice volume 49 which is formed around the tube 31 serving as the partition wall 37, is replaced by the fuel flushing through the first channel 33 of the fuel distributor 1 due to the large surface area of the e.g. Tube 31 arranged concentrically to the fuel supply line 29 is particularly well cooled.
  • FIG. 1 A third exemplary embodiment according to the invention is shown in FIG.
  • the same and equivalent parts are identified by the same reference numerals as in Figures 1 to 4.
  • a fuel supply line 29 is formed in the fuel distributor 1 which serves to supply fuel to the fuel injection valves 3, for example has a circular cross section and is connected to the valve receiving openings 5 by means of overlapping openings 38.

  • the fuel distributor 1 according to the invention can e.g. by injection molding a metal or a plastic or also by forging a metal, e.g. of aluminum.
  • the tube 31 or the strip 57 are e.g. insert into the mold before injection molding.
  • a fuel distributor 1 according to the invention in an internal combustion engine enables spraying by forming a fuel reservoir with fuel free of vapor bubbles in the first seconds after the internal combustion engine has been hot started vapor-free and thus good ignitability fuel by the fuel injection valves and thus a reliable starting of the internal combustion engine and subsequent stable operation of the internal combustion engine.
