Definitions

  • the invention relates to an arrangement for mounting an injector on a motor vehicle engine cylinder head.
  • an injector generally has a generally cylindrical shape elongate along a main axis.
  • the injector can also be arranged in a form injector holder cylindrical.
  • injector will refer to an injector alone or to an assembly formed by the injector and the injector holder if appropriate.
  • the injector has a first lower section which is intended to extend inside the cylinder head to a free lower end.
  • the free bottom end has an injection nozzle which opens into the combustion chamber of the engine.
  • the nozzle is controlled to release one or more jets of fuel into the combustion chamber. It is common that the fuel jets are emitted with an inclination with respect to the axis of the injector.
  • the injector also has a second upper section which is intended to extend above the upper face of the cylinder head of the engine.
  • This second section comprises connection means with supply lines and fuel return. It also has electrical connectors to allow control of the injector.
  • the flange is mounted on the injector by transverse interlocking in the lateral notches.
  • the lower section of the injector and equipped with the flange is then inserted into a well of the cylinder head.
  • the flange is attached to the cylinder head, usually by means of a screw axis parallel to that of the injector.
  • engine compartments are increasingly crowded. In this context, it seeks to reduce the size of the engine. As a result, the engine cylinder head has an increasingly compact upper face. The various components carried by the cylinder head, including camshafts, must therefore be housed in a space increasingly reduced.
  • an engine design has been proposed in which the perimeter of the cylinder head cover is arranged at a distance above the cylinder head.
  • the cylinder head cover shall be sealed to the cylinder head to prevent lubricating oil from the moving components carried by the cylinder head from coming out of the space between the cylinder head and the cylinder head cover. This sealing also makes it possible to prevent said mobile components from being fouled by external particles.
  • the injectors have a length such that the upper section of the injector protrudes above the cylinder head cover by means of an insertion orifice.
  • the insertion orifice has a diameter substantially equal to the diameter of the lower section of the injector, and a seal is arranged between the cylinder head cover and the injector.
  • the upper section of the injectors has a larger overall diameter than the lower section.
  • the injector must therefore be inserted into the well of the cylinder head after positioning the cylinder head cover by passing through the insertion hole.
  • the fixing flanges of the injectors are preferably fixed to the cylinder head, either directly or via a support of shafts. cams which is itself fixed flat against the upper face of the breech.
  • the fixing of the flanges to the cylinder head cover would not make it possible to obtain a sufficiently precise position in the position because the cylinder head cover is generally formed by a plate made of thin sheet or plastic which is able to vibrate with respect to the cylinder head during the engine operation.
  • the fixing flanges being positioned on the cylinder head before the positioning of the cylinder head cover, they are difficult to access when inserting the injector into the well. It is then impossible to fit the fork of the flange on the injector.
  • the invention provides an arrangement for fixing an injector on a cylinder head cover when the flange is inaccessible at the time of insertion of the injector into the bolt hole.
  • the invention naturally makes it possible to solve other technical problems, especially if it is desired to change the order of the injector mounting operations, for example to simplify the mass production of heat engines.
  • the invention proposes an arrangement of the type described above, characterized in that the two holding elements are mounted movably transversely between a spaced apart position in which they are spaced a distance greater than the largest diameter of the injection section and a close position to which they are resiliently biased and wherein each holding member is capable of being fitted transversely into the associated lateral notch.

  • the yoke 10 has a planar upper face 14 which is hollowed out with various cavities for receiving a plurality of parts such as intake valves and exhaust valves (not shown).
  • the upper face 14 of the yoke 10 is also intended to support two cam shafts 16 of longitudinal "B" axis which extend symmetrically on either side of the plane "P" of alignment as shown in FIG. figure 4 .
  • the camshafts 16 are rotatably mounted about their axis "B" on the cylinder head 10 via a support 18, sometimes referred to as the "beam".
  • this support 18 is in the form of a rectangular horizontal plate sufficiently thick to have a high rigidity.
  • the support 18 is thus delimited vertically by a lower horizontal face 20 and an upper horizontal face 22.
  • the plane “P" alignment here cuts the support 18 along its median longitudinal axis.
  • the support 18 comprises bearings (not shown) for rotatingly receiving the two camshafts 16.
  • the support 18 further has recesses which allow valve stems (not shown) to come into contact with the cams of the camshaft 16 via latches.
  • the lower face of the support 18 is pressed against the upper face 14 of the yoke 10.
  • the support 18 thus positioned is fixed rigidly with the yoke 10.
  • the upper horizontal face 22 of the support 18 is perfectly fixed by relative to the upper face 14 of the cylinder head 10 over its entire surface.
  • a component fixed against the upper face 22 of the support 18 remains positioned perfectly fixed with respect to the cylinder head 10 even during operation of the engine.
  • a cylinder head cover 24 covers the upper face 22 of the support 18, as illustrated in FIGS. figures 1 and 4 .
  • the cylinder head cover 24 is in the form of a thin sheet of which two longitudinal edges 26 are bent downward so as to come into contact with the upper face 22 of the support while the central part of the head cover 24 is arranged at a distance above the upper face 22 of the support 18 to allow the housing the two camshafts 16 in a free space reserved between the cylinder head 10 and the cylinder head cover 24.
  • the valve cover 24 is thus fixed to the support 18 via its two longitudinal edges 26.
  • the central portion of the cylinder head cover 24 is arranged at a distance above the cylinder head. It is therefore subject to vibration with respect to the cylinder head 10 when the engine is in operation.
  • Injectors 28 are arranged on the cylinder head 10. For the sake of clarity of the drawings, there is shown in the figures a single injector 28 arranged on the cylinder head 10. However, it will be understood that such an engine comprises several injectors 28 each of which is associated with a combustion chamber 12. All the injectors 28 of the engine are identical and they are similarly arranged on the cylinder head 10.

  • a washer is generally interposed between the shoulder 38 and the seat 40 to allow the height adjustment of the jets and to guarantee the tightness.
  • the upper portion 32 of the injector 28 has a larger radial size than the lower section 30.
  • This upper section 32 comprises connection means with a reserve of fuel under pressure as well as electrical connectors to enable the control of the emission of fuel jets.
  • the cylinder head cover 24 has an insertion orifice 41 of shape complementary to an upper end portion of the lower section 30.
  • a seal is interposed radially between the lower section 30 and the cylinder head cover 24 to ensure the tightness of the space defined between the cylinder head cover 24 and the cylinder head 10.
  • the upper section 32 and the lower section 30 are releasable relative to one another or at least they must be mounted together prior to mounting the injector 28 on the cylinder head 10. Due to the radial size of the section 32 greater than the diameter of the insertion hole 41, the injector 28 is necessarily inserted vertically into the well 36 after the cylinder head cover 24 has been positioned.
  • the injector 28 must be held firmly relative to the cylinder head 10 to prevent it from being lifted from its seat 40 in response to the emission of a jet of fuel and / or the pressure exerted in operation. in the combustion chamber.
  • the injector 28 must also be indexed angularly so that the fuel jets are emitted in a predetermined direction.
  • the lower injection section 30 comprises an upper portion of fastener comprising at least two transversely opposed lateral notches 42, as illustrated in FIGS. figures 2 and 5 .
  • Each notch 42 is formed by a longitudinal groove whose bottom 44 forms a flat.
