Definitions

  • the present invention refers to the field of connections of high-pressure pipes for distributing high-pressure fuel to the injectors when the high-pressure rail is external to the head of the internal combustion engine.
  • Common rail injection systems comprise a high-pressure fuel pump that supplies a so-called common rail. Smaller pipes branch off from the common rail (or simply rail) pipe to supply each single injector.
  • the rail comprises a number of connectors, generally referred to as sleeve nipples, the number of which is the same as the number of injectors to be supplied.
  • the same number of high-pressure pipes are connected to these connectors, by means of complementary connectors, preferably screwed, to supply the injectors. Said pipes are normally called injector pipes.
  • the rail may be obtained by welding the connectors or by casting or forging the rail in a single piece.
  • the pressure inside the tappet compartment is different from the ambient pressure.
  • an overpressure is created with respect to the external pressure, and it is therefore necessary to seal the points in the wall of the tappet compartment through which the high-pressure fuel pipes pass.
  • Passing-wall are used for that purpose, that is to say, tubular elements that are fixed transversely to a part to be crossed, using connecting means provided with specific sealing gaskets.
  • the fittings of the high-pressure pipes used for fuel injection systems are manufactured to withstand extremely high pressures and made of deformable metal material to guarantee the required sealing properties.
  • a high-pressure fitting can only be used once. Therefore, when an injector has to be disconnected, the fittings of the pipes that are disconnected, including any so-called "passing-wall", must be replaced.
  • the purpose of the present invention is to reduce the components used for the hydraulic connections of a common rail fuel circuit, in which the rail is external to the head and specifically external to the tappet compartment of the internal combustion engine.
  • the idea at the basis of the present invention is to use the output connectors of the rail to pass through respective through holes in a wall of the cylinder head to enter the tappet compartment and to use the same output connectors as caps for said through holes.
  • the output connectors produced in one piece with the common rail, consist, according to the present invention, in a set of caps joined and integral with one another through the common rail suitable to close corresponding through holes in a wall of the head of the internal combustion engine.
  • the fittings are made in one piece with the rail and each fitting comprises an annular base with a flat contact surface complementary to the wall of the head of the engine. Between said complementary surfaces there is a flat annular gasket through which the respective fitting passes.
  • Means for fastening the rail to the head of the internal combustion engine keep the rail pressed against said head, to guarantee the necessary uniform compression of the annular gaskets.
  • the first solution based on radial gaskets, is particularly advantageous for implementations in which the rail is produced by means of welding, in that it enables the backlash and machining tolerances to be recovered.
  • the high-pressure pipes that branch off from the rail can all be the same and interchangeable.
  • the second solution based on flat annular gaskets, is particularly advantageous in implementations in which the rail is produced by means of casting or forging, and in particular when the machining tolerances of the rail are such to enable a high degree of precision in the assembly of the head of the engine.
  • An object of the present invention is cylinder head of an internal combustion engine provided of a common rail external to the head and a sealing system, as claimed in claim 1.
  • Another object of the present invention is a method for sealing a head of an internal combustion engine with common rail external to the head.
  • Another object of the present invention is an internal combustion engine provided with said sealing system.
  • a further object of the present invention is a vehicle or fixed installation provided with said internal combustion engine.
  • second component does not imply the presence of a "first” component. Such terms are simply used for the sake of clarity and should not be considered as limiting the scope of the invention.
  • Figures 1 and 2 illustrate a head H of an internal combustion engine E with common rail CR external to the head.
  • the common rail has a longitudinal tubular shape, perpendicular to the sheet of the drawings.
  • the common rail has two or more output connectors SN in one piece with the common rail and distributed along said common rail and aligned with one another so as to lie on a common plane PL.
  • the output pipes in turn, extend axially in a tubular shape that intersects the common rail.
  • the axes of extension of the output connectors lie on the same common plane PL.
  • the common rail has a circular cross section, the fact that the output connectors SN are aligned with one another so as to lie on a same common plane PL, corresponds to the fact that they intersect the common rail in a same angular position, even though they are distributed along the longitudinal extension of said common rail.
  • the head H of the internal combustion engine E comprises a wall HW provided with through holes TH in the same number as said two or more output connectors SN.
  • the sealing system is defined by
  • the sealing means G consist of a radial gasket, concentrically inserted into the through holes TH so as to at least partially engage a related thickness TK.
  • each through hole TH comprises an annular stop tooth TD1 which determines the axial stop of the radial gasket G during insertion of the related output connector SN into the corresponding through hole TH.
  • the stop tooth TD1 is therefore implemented so as to prevent the radial seal from falling into the tappet compartment TH.
  • the output connectors SN preferably have a tapered shape and define a base area B, in one piece with the common rail, which defines a sort of transition zone between the common rail and the output connector, which defines another stop tooth TD2 suitable to maintain the radial gasket G in the respective through hole TH, when the common rail is operatively associated with the head H of the internal combustion engine E.
  • the axial section of the radial seals G defines a sort of W capable of recovering any relevant backlash and tolerances in the distribution of the output connectors along the common rail, which could occur in case of common rails produced by welding.
  • the radial gasket G has a substantially cylindrical shape with a knurled outer cylindrical wall GWE to ensure better adherence to the respective seat obtained in the through holes TH - i.e. in the thickness TK of the wall in which the through holes are obtained.
  • the face F1 of the gasket G is visible from the outside of the head H of the engine.
  • Said face F1 preferably defines an annular stop tooth GTD that cooperates with the stop tooth TD1 to prevent the gasket from falling into the tappet compartment.
  • the smaller base of the inner truncated cone shaped wall has a diameter comprised between 10 and 16 mm, with a preferred value of 13.5.
  • Said smaller base cooperates with the output connector SN which has, at least in the portion that comes into contact with said gasket G, a cylindrical shape.
  • said cylindrical portion has a diameter comprised between 16 and 10 mm, with a preferred value of 13 mm.
  • said sealing means consist of a flat annular gasket G1 interposed between the outer face HWE of the wall HW of the head of the engine E and the base B of the output connector SN.
  • Both the outer wall HWE and the base B define respective flat surfaces TD1 and TD2 complementary to each other between which the flat annular gasket G1 is interposed.
  • the surfaces TD1 in figure 2 are preferably obtained by milling the outer face HWE of the wall HW.
  • the radial gaskets G produce a synergistic effect with this method of production of the common rail.
  • each one has a first end provided with a connector EJPC1 complementary to an output connector SN of the common rail and a second end opposite the first end provided with a connector EJPC2 complementary to the connector of the injector EJ.
  • figure 4 shows a common rail having a shorter extension than that of the head H of the engine.
  • a tappet cover closing the top of the compartment TPF in which the valve actuating tappets are housed is not shown, but is implicit.
  • the springs VS of the valves are clearly visible.
  • FIGS 5 and 6 A further comparison between the common rails is illustrated in figures 5 and 6 .
  • the linear sequence 1 - 6 of the common rail is ordered, whereas in figure 6 the numbers 3 and 4 are inverted.
  • the solution in figure 5 envisages a far smaller number of fastening points FM than the solution in figure 6 .
  • the flat annular gaskets G1 of figures 2 , 4 and 6 require low tolerances between the couplings TD1 and TD2 and a good connection pressure.
  • Fastening screws SC clearly visible in figures 1 and 2 , are inserted through the flanges defined by the fastening points, in one piece with the rail.
