Definitions

  • the present invention relates to an air inlet connector of a turbocharger of a motor vehicle engine.
  • the present invention more particularly relates to a turbocharger air inlet connector having a connection with a burnt gas recirculation circuit.
  • the present invention also relates to a heat engine comprising a turbocharger.
  • a turbocharger is one of the three main known supercharging systems generally used on internal combustion engines, gasoline or diesel, intended to increase the power density, the other two being the supercharger and the gas injection.
  • the principle of said systems is to increase the pressure of the admitted gases, allowing a better filling of the cylinders in mixture "air / fuel", thereby increasing the power density of the engine to increase power or reduce consumption with a smaller displacement engine.
  • NOx nitrogen oxides
  • blow-by gases mainly composed of air, which can come from the combustion chamber of the engine or other motor organs and which are passed through the piston rings and from the bottom of the crankcase where they are loaded with liquid oil, in the form of fine droplets. According to antipollution standards, these gases can not be released directly into the atmosphere, are then reinjected to the intake after being removed from their oil in order to avoid reducing the efficiency of combustion and thus increase toxic emissions.
  • the blow-by gases are therefore an air / oil drop mixture, where the drops are very diluted.
  • the filtering of the blow-by gases can be carried out in a known manner by decantation.
  • the decantation process consists of circulating the particle-laden gases in a decanter comprising a chamber equipped with baffles.
  • the oil collected by impaction is then returned essentially by gravity in the bottom of the crankcase by means of cannulas whose inlet is often placed at the bottom of the decanter.
  • Deoiled gases are in turn sent back into the air intake circuit in an intake manifold disposed upstream of the turbocharger.
  • the different inlet gas flows have different characteristics and they can not be mixed abruptly with one another at a single collection point.
  • the blow-by gases and the gases coming from the EGR circuit can thus not easily coexist and in particular the oil residues that may still be present in the blow-by gases must not reach a hot inlet of the EGR valve. under threat of fire.
  • the fresh air is supplied from an air filter by an air duct generally made of plastic with a rubber base.
  • EPDM is in known manner used for the manufacture of said conduits.
  • the burnt gases from the EGR circuit or the blow-by clarifier are generally incompatible with certain rubber bases used in the manufacture of an air duct. They can not be collected in the air duct with fresh air. Said burned gases must therefore be introduced into a rigid manifold such as an input connector of the turbocharger.
  • Said connector may have a shape adapted to improve the gas inlet velocity in the compressor of the turbocharger and the flow rate of said gas.
  • the fresh air flow portion in said connector is conically shaped to improve the fresh air flow rates at the turbocharger inlet.
  • the burned gases are thus led through a conduit to the turbocharger inlet connector where they join the fresh air.
  • the directions of the two flows of burnt gas and fresh air are substantially orthogonal in order to improve the mixing of the gases at the inlet to the turbocharger, but the flow of the burned gases can be significant and prevent the flow of Fresh air also arrives at the turbocharger or at least reduces the flow of fresh air creating a high pressure drop.
  • Geometry also causes an increase in the pressure drop of the fresh air flow. Indeed, the flow of recirculated gas opens a substantially cylindrical conduit in the conical shaped turbocharger inlet connector. The wall rupture due to the outlet of recirculated gas can then cause shocks and therefore pressure drops.
  • turbocharger inlet connector adapted to collect the flows of burnt gas, deoiled gas and fresh air having different characteristics and connected to the inlet of a turbocharger and allowing an optimal flow said mixed gases to the inlet of the turbocharger.
  • the publication FR-A1-2950659 discloses an input connector of a turbocharger capable of collecting the flow of gas from a circuit of burnt EGR recirculated gas and fresh air from an air filter.
  • Said connector is adapted to bring the flow of gas from the burnt gas recirculation circuit to be diffused into the fresh air flow before the compressor wheel.
  • Said connector comprises a substantially conical seal comprising holes for the diffusion of the burnt gases in the flow of fresh air flowing along the axis of the cone.
  • the connector comprises an additional piece which is the conical seal derived from a rubber-based material, which makes it difficult to connect the duct with de-oiled gases, especially if the bulk is an important factor. .
  • a disadvantage is that said connector is complex and expensive to produce.
  • One of the aims of the invention is to overcome these drawbacks and the subject of the invention is a turbocharger input connector of a heat engine capable of receiving a flow of recirculating gas, a stream of gases coming from settling and a flow of fresh air and bring the mixture of flows to the turbocharger by optimizing the circulation of gases and improving the mixing of said gases from their mixing point to the inlet of the turbocharger.
  • the outlet of the recirculated gas supply duct comprises a diffusion wall flush with the surface of the wall of the main duct to reduce the obstacles to the flow of fresh air and therefore the pressure drops.
  • the diffusion wall also makes it possible to reduce the impact of the introduction of recirculated gases into the fresh air flow.
  • the conical shape of the main fresh air duct makes it possible to increase the speed of the mixed gases at the inlet to the turbocharger.
  • the upstream and downstream terms refer to the flow direction of the gases before entering the turbocharger.
  • an input connector 10 is attached to the inlet of a turbocharger (not shown), said connector comprising an inlet for fresh air flows 11, an inlet for recirculated gas flows 12 from a quilting from the exhaust gas circuit preferably downstream of pollution control systems such as a nitrogen oxide catalyst or trap, and an inlet for de-oiled gas streams 14 taken from a decanter (not shown).
  • Recirculated gases and deoiled gases containing substances that may have reactions with rubber elements for example can not therefore be collected in a flexible conduit such as a fresh air supply duct. It is known to collect the flows of the different gases in a rigid element such as an input connector disposed at the inlet of a turbocharger.
  • the input connector 10 is made of rigid material, preferably thermoplastic. It comprises a support wall 16 having fastening holes 13 to be traversed by fixing screws (not shown) for securing said support wall 16 of the input connector 10 against the inlet of the turbocharger. Said support wall 16 has an orifice 18 opening into the inlet of the turbocharger.
  • the input connector 10 comprises a main conduit 20 connected to a fresh air supply circuit downstream of an air filter.
  • Said main duct 20 is preferably conical in order to increase the speed of the gases entering the turbocharger.
  • the input connector includes a connection with a recirculated gas circuit or "EGR" for Exhaust Gas Recirculation in English from a burnt gas exhaust system.
  • Said connection includes a channel supplying substantially cylindrical recirculated gas 21 dug in the connector 10 and opening substantially orthogonal in the main conduit 20 to improve the mixing of the gases at the inlet into the turbocharger.
  • Said supply channel is connected with a recirculated gas supply duct 22.
  • the axis of said recirculated gas supply channel X1 is therefore orthogonal to the axis X of the main duct 20.
  • the recirculated gas supply duct 22 comprises a tubular element 23 preferably bent in order to reduce the size of the connector and comprises a tubular upstream end adapted to be connected to a burned gas duct (not shown), and an end substantially tubular downstream adapted to be inserted into the recirculated gas supply channel 21.
  • said outlet of the recirculated gas supply channel 21 in the main duct 20 is masked by a diffusion wall 25 which is flush with the surface of the wall 24 of said main duct, which reduces the asperities at the surface of the duct wall. main effect with the effect of reducing turbulence near said outlet.
  • the term "flush" means that the shape of the diffusion wall 25 substantially matches the shape of the wall 24 of the main duct 20 without presenting asperities with respect to the wall 24 of the main duct.
  • the diffusion wall 25 comprises a substantially central main conical aperture 31 surrounded by at least one substantially conical auxiliary orifice at the periphery 32 of the diffusion wall.
  • the axes of the median and peripheral conical orifices are substantially parallel to each other and open substantially orthogonal to the diffusion wall 25 in the main duct.
  • Said conical orifices have a narrowed section 33 facing the main duct 20.
  • the diameter of the narrowed section 33 of the auxiliary orifices is substantially smaller than the diameter of the narrowed section 33 'of the median main orifice 31.
  • the diameter of the narrowed section 33 said narrowed section 33 of the auxiliary orifices at the periphery 32 is of the order of 1 mm while the diameter of the narrowed section 33 'of the main orifice 31 is of the order of 3 mm.
  • the diffusion wall 25 comprises a grid 41 fixed to the wall 24 of the main duct 20, said grating comprising at least one bar 42 extending preferably in a direction orthogonal to the axis of the main duct and substantially parallel to the wall 24 of the main duct 20.
  • the figure 5 thus represents the diffusion wall 25 which comprises a succession of parallel bars 42 extending along an axis X 2 orthogonal to the axis X of the primary duct 20.
  • the said bars may be fixed to an annular frame 43 whose external diameter is substantially equal to the diameter of the outflow of the supply channel 21 of recirculated gas.
  • Said frame 43 is fixed to the wall 24 of the main duct by welding or gluing.
  • the diffusion wall comprises a grid 51 comprising a multitude of orifices 52 of small diameter of the order of 1 to 2 mm distributed over the entire surface of said diffusion wall 25.
  • Said diffusion wall 25 masks the outlet of the recirculated gas duct 21 in the main duct 20 and the surface of said diffusion wall facing the main duct is in continuity with the surface of the wall 24 of the main duct.
  • the diffusion wall 25 thus has a portion of curved surface in the extension of the surface of the wall of the main duct.
  • Said diffusion wall can be fixed to the cylindrical duct 22 of recirculated gas or be integral with the inlet connector 10.
  • Said diffusion wall 25 can thus be fixed to the downstream end of the supply duct 22 of the recirculated gases by gluing or welding.
  • Said conduit for supplying recirculated gases is then pressed into the supply channel 21 of the recirculated gases.
  • said supply conduit 22 comprises a blister on the outer cylindrical surface complementary with a groove dug in the supply channel 21 of recirculated gas to serve as a foolproof.
  • the diffusion wall 25 and the inlet connector 10 of the turbocharger may also be of a piece obtained by molding in order to reduce the number of operations for obtaining the connector.
