Definitions

  • the invention relates to a fuel distributor for fuel injection systems of internal combustion engines of the type defined in the preamble of claim 1.
  • Such a fuel rail is known from DE 37 30 571 A1 or from DE 32 28 508 A1.
  • the attachment to the internal combustion engine takes place via webs or flanges with through holes arranged on the distributor housing, through which a screw is passed and screwed on the internal combustion engine side.
  • the working noises of the fuel injection valves and the pressure pulsations which are caused by the timing of the fuel injection valves, are transmitted to the adjacent components, such as the intake manifold of the internal combustion engine, and lead to unpleasant noise in the engine compartment of the motor vehicle.
  • an elastic ring is provided in a known so-called top-feed fuel injection valve (DE 28 27 850 A1), which is inserted directly into a connecting piece on the intake manifold and is enclosed by a holder clamped on the intake manifold, which non-positively surrounds the fuel injection valve is placed and on which the holder engages.
  • the fuel distributor according to the invention with the characterizing features of claim 1 has the advantage that it is largely sound-decoupled from the adjacent components even in the design with a distributor housing which receives a number of fuel injection valves in fuel-flushed receiving bores corresponding to the number of cylinders of the internal combustion engine. As a result, extensive noise reduction in the engine compartment of the vehicle is achieved even when using a fuel distributor of the type described in the introduction.
  • each vibrating metal element is formed by an elastic sleeve, eg made of elastomer and a clamping element that can be anchored to the intake manifold.
  • the elastic sleeve is inserted in mutually aligned through bores in the distributor housing and hold-down device, and the clamping element penetrates the sleeve with radial pressure on the sleeve against the bore walls and overlaps the sleeve with a clamping shoulder, the diameter of which is not greater than the outside diameter of the sleeve.
  • the clamping element consists of a clamping screw and a metallic spacer sleeve surrounding the screw shaft.
  • the spacer sleeve abuts the screw head and the mounting flange of the intake manifold so that the fuel rail can be attached to the mounting flange of the intake manifold with a defined torque.
  • the diameter of the screw head is slightly smaller than the diameter of the elastic sleeve surrounding the spacer sleeve, so that the vibrating metal character is retained.
  • the holding-down device also forms the contact strip for the electrical contacting of the electromagnetically actuated fuel injection valves
  • the connecting cables leading to the plug contacts in the contact strip are fixed in the cable channels provided in the holding-down device, e.g. by mechanical fasteners or by pouring or foaming. This avoids free, oscillatory conductor cross-sections and also prevents noise.
  • the distributor housing and hold-down are suitably made of plastic, but can also be made of metal.
  • the drawing shows a section of a cross section of a fuel distributor for a fuel injection system of an internal combustion engine.
  • the fuel distributor shown in cross section in the drawing has a plastic distributor housing 10, in which a plurality of receiving bores 11 are contained.
  • the number of receiving bores 11 corresponds to the number of cylinders of the internal combustion engine, so that four receiving bores 11 are provided in the distributor housing 10 for a fuel distributor for a four-cylinder internal combustion engine.
  • Each longitudinally continuous and stepped receiving bore 11 has a longer bore section 111 and a bore section 112 and 113 upstream and downstream of the bore section 111, the bore section 112 having a larger bore diameter and the bore section 113 having a smaller bore diameter than the central bore section 111.
  • the bore section 113 ends with an orifice opening 12 and protrudes after assembly into an injection opening 14 formed in an intake manifold 13 of an internal combustion engine.
  • a mounting flange 49 is provided on the intake pipe 13, on which a support surface is placed with the interposition of an elastic sealing ring 15 made of elastomer 16 rests, which is arranged on the distributor housing 10 coaxially to the receiving bore 11 and set back from the opening 12 of the receiving bore 11.
  • an electromagnetically actuated fuel injection valve 17 of a known type is used in each receiving bore 11, an electromagnetically actuated fuel injection valve 17 of a known type is used.
  • a fuel injection valve is shown in detail, for example, in DE 37 05 848 A1.
  • the fuel injection valve 17 lies in the bore section 112 with a housing flange 18 and in the bore section 113 with an orifice connection 19.
  • the bore section 111 which is connected to a fuel supply line that cannot be seen here, is liquid-tightly closed by two O-rings 20, 21, which are supported radially on the one hand on the fuel injection valve 17 and on the other hand on the bore wall in the bore section 111 or 113.
  • a complete distributor housing 10 with inserted fuel injection valves 17, in which the course of the fuel supply line can also be seen, is shown in DE 37 30 571 A1.
  • a holding-down device 22 made of plastic which rests with a clamping flange 23 on a support flange 24 on the distributor housing 10 and overlaps the housing flange 18 of the fuel injection valve 17. With this overlap area of the clamping flange 23, the hold-down device 22 holds the fuel injection valves 17 in the distributor housing 10.
  • a continuous flat gasket 25 made of elastomer is inserted between the clamping flange 23 of the hold-down device 22 and the carrier flange 24 of the distributor housing 10.
  • the hold-down device 22 is also designed as a so-called contact strip, which contains sockets 26 and connecting cables 27 leading to the sockets.
  • the sockets 26 are arranged so that they are when the Push the hold-down device 22 onto the distributor housing 10 via pins 28 on the fuel injection valves 17.
  • the power supply to the electromagnets of the fuel injection valves 17 is established via the connecting cables 27, sockets 26 and pins 28.
  • the connecting cables 27 are laid within the hold-down device 22 in cable channels 29. To avoid the development of noise, the connecting cables 27 are fixed in the cable channels 29, in the exemplary embodiment by a mechanical cable holder 30. To fix the connecting cables 27, the cable channels 29 can also be poured out or foamed.
  • Both the connection between the hold-down device 22 and the distributor housing 10 and also the fastening of the complete fuel distributor to the fastening flange 49 of the intake pipe 13 takes place by means of so-called vibrating metal elements 31 and 32.
  • Each vibrating metal element 31 or 32 is composed of a clamping element 33 or 34 and one this enclosing elastic sleeve 35 and 36 made of elastomer.
  • the elastic sleeve 35 is inserted into a through hole 37 in the distributor housing 10, while the elastic sleeve 36 is inserted into two mutually aligned through holes 38 and 39 in the distributor housing 10 and in the hold-down device 22.
  • the clamping element 31 penetrates the elastic sleeve 35 under radial pressure against the bore wall of the through bore 37 and is anchored in the hold-down device 22.
  • the clamping element 34 penetrates the elastic sleeve 36 in the same way with radial pressure on the bore walls of the through bores 38 and 39 and is anchored in the mounting flange 49 on the intake pipe 13.
  • the clamping element 33 or 34 overlaps the associated elastic sleeve 35 or 36 on its end face facing away from the anchoring with a Clamping shoulder 40 or 41, which is not larger than the outer diameter of the elastic sleeve 35 or 36.
  • Each clamping element 33, 34 is formed by a clamping screw 42, 43 and a metallic spacer sleeve 44 or 45 surrounding the screw shaft.
  • the undersides of the screw heads each form the clamping shoulders 40 and 41.
  • Corresponding threaded bushes 46 are inserted into the hold-down device 22, in each of which one of the clamping screws 42 is screwed in with a defined tightening torque.
  • the spacer sleeve 45 protrudes slightly on the underside of the distributor housing 10 facing the mounting flange 49 of the intake pipe 13, so that a small gap 48 remains between the distributor housing 10 and the mounting flange 49 of the intake pipe 13 when the fuel distributor is braced on the intake pipe 13.
  • the elastic sleeve 36 can also protrude by the same amount over the distributor housing 10, but this is not mandatory.
  • the screw shaft of the clamping screw 43 is also screwed into a threaded bore 47 in the mounting flange 49 with a defined tightening torque.
  • the two spacer sleeves 44, 45 enable the application of a precisely defined tightening torque of the clamping screws 42, 43 to the plastic design of the distributor housing 10 and hold-down device 22.
  • the distributor housing 10 and hold-down device 22 can also be made of metal with the fuel distributor being otherwise of the same construction.
