Definitions

  • the invention relates to a device for supplying air to a multi-cylinder engine cylinder head comprising two rows of air intake ducts to the cylinders.
  • such an air supply device comprises a first and a second air distributors arranged, or to arrange, and to fix on the cylinder head, along the air mouths of said air inlet ducts of this cylinder head, which communicate with the combustion chambers of the cylinders.
  • Such air distributors formed by a first and a second air distributor are typically present on in-line V-engines, for example 6-cylinder engines.
  • the air distributors are supplied with air via an air distributor means.
  • the air distributor means is integrated in one piece with one of the air distributors and is sealingly connected to the other air distributor via a press fit connection using an O-ring for the air distributor. seal.
  • An air supply device of a multi-cylinder engine cylinder head according to the preamble of claim 1 is also known by the US-A-4,811,697 .
  • the air supply means for the cylinders will therefore comprise, overall, three main parts: the upstream air distributor and the two downstream air distributors, with optimized positioning, centering and fixing means.
  • the air distributors are each connected, at a first end of their direction of elongation, to an upstream air distributor and / or, at a second downstream end, opposite the first, to an air transfer pipe promoting the good distribution of air there.
  • one or other of these "air distributor” and “air transfer manifold” can be made as before and it is recommended that this implementation is preferably applied at least to the input air distributor (upstream) which will therefore include several internal conduits (a priori divided into three) with three air mouths, one receiving external air (typically to from a throttle body), the other two being therefore arranged in front of the corresponding air mouth of the splitters.
  • both the upstream air distributor and the aforementioned downstream air transfer pipe (s) are made with the positioning, centering and fixing means presented above. .
  • the first complementary sliding pivot positioning means between the air distributor and the air distributor concerned will comprise an annular skirt, projecting around the corresponding mouth of the air distributor, this skirt closely covering an outer edge the corresponding mouth of the distributor facing him, to ensure a substantially no radial play interlocking along said axis of engagement.
  • FIG 1 two air distributors 1, 3 are shown, designed in a manner known per se, for distributing the intake air to the two series of air inlet mouthpieces (marks 5a, 5b, 5c for the one of them) of a cylinder head 9 of multicylinder engine 11 covering a crankcase of the engine.
  • Each air distributor 1, 3 comprises at least one air intake mouth and a plurality of mouths, or groups of mouths, air distribution or outlet to said corresponding air mouth of the cylinder head 9.
  • These mouths have end surfaces, such as 15 for the mouth 1d, which serves as a support, and 17 for the mouth 3d, which has along the axis of engagement 30 a clearance e with the surface 25 opposite ( see figure 4 ).
  • FIG. 1 21a locates the air inlet zone in the dispenser 19 (see also figure 3 ). The air is thus admitted substantially parallel to the axes 10 and 30.
  • these surfaces 17 and 25 will therefore, axially, in the immediate vicinity, one in front of the other, when the parts 1, 3 and 19 will be fixed together, after being correctly positioned and centered, according to the invention.
  • said surfaces will be planes.
  • these planes are perpendicular to the axis 10 or 30 considered, the axis 30 constituting the axis of engagement along which we will approach, and here engage, the outlet mouth of the distributor 19 on the mouthpiece 3d, sliding pivot.
  • said surfaces or support planes will cooperate in pairs to correctly connect and position the air distributor 19 vis-à-vis each of the two distributors 1, 3, with the mouths and surfaces concerned in support or face to face.
  • the fitting 27 is favorably realized, as illustrated figures 1 , 3 and 4 by a skirt 37 formed around the mouth 21c, this over the entire periphery of the corresponding end flange.
  • this skirt 37 covers the end of the mouthpiece 3d of the distributor tightly and externally, until it is therefore placed axially as close as possible to the end surfaces 17, 25, as explained above, the seal 35 then being compressed radially.
  • three screws 39a, 39b, 39c have been used which can pass for at least some with clearance (in their unsealed state) two sets of three holes, such as 41a and 43a for the screw 39a which will serve to ensure the locating effect sought, in connection with the corresponding orifice 41a and its vis-à-vis 43a, said holes being formed through the rim of one side of the mouth 1d, and the other of the mouth 21b, and thus through the aforementioned surfaces 15 and 23 transverse to the axis 10 common to these two mouths.
  • the threads of the screws 39a, 39b, 39c engage threads formed in the three holes (such as 43a) of the flange 15 of the distributor 1.
  • the displacement 29 is stopped at the location of the bearing surface 15, by the engagement of the screws in their holes, such as the hole 41a, here formed in the outer rim 45 of the air distributor.
  • the screw 39a also serves for locating, the three screws forming here the fastening means 33 can then be clamped on the distributor 1, through their corresponding holes, to ensure the desired tight attachment.
  • the two air distributors 1, 3 can also be interconnected by the same isostatic assembly system acting without deformation of the parts, since at this end we will have provided, as illustrated figure 2 , to connect their corresponding mouths 50, 51, via an air transfer tube 53.
  • the positioning, centering and fixing means which may be identical to those presented, have not been illustrated; but we can easily imagine them, identical to those mentioned above.
  • This air transfer pipe 53 will therefore preferably bear the same means 27, 31, 33 for positioning and centering (sliding pivot, surface support, locating,) and fastening as the distributor 19.
  • the axis of engagement (previously 30) between the air transfer tube 53 and the air distributor 3 has been identified 60.
  • the difference between the distributor 19 and the air transfer manifold 53 here relates to their internal construction.
  • the distributor 19 here comprises three main air ducts: one for admission (on which opens its air intake opening 21a) the other two bringing air to the respective outlet mouths 21b and 21c, these three conduits of course communicating with each other inside the dispenser.
  • the air transfer tube 53 contains only one duct, with an opening, respectively 55 and 57, at each end, to let air circulate between the two air distributors 1 and 3, respectively. opposite of the inlet distributor 19.
  • FIG. 2 at 59, where there has been a recirculating air inlet (EGR) which can arrive transversely in the air intake distributor 19.
  • EGR recirculating air inlet
