Definitions

  • the present invention relates to an air intake duct arrangement of an internal combustion engine whose cylinder head is fixed to the body of a motor vehicle by means of a damping element, said cylinder head being closed by a set of distribution casings, and said intake duct consisting of an intermediate portion connected on the one hand to an upstream portion connected to a heat exchanger, and on the other hand to a downstream portion conveying the air in the direction of an intake manifold, fixed on the intermediate portion.
  • the conduits for supplying the engine with gas or for recovering exhaust gases are not installed so as to optimize the flow of gases.
  • these ducts are positioned in the cramped structure of the engine block, between wiring, water pipes, air conditioning ducts and fuel ducts.
  • this type of duct sinfully bypasses the engine block and the structure, constraining the shape of the duct to the detriment of its function.
  • One of the disadvantages of the air intake ducts of an engine is that they take up space in the engine compartment and they do not facilitate the integration of other components.
  • the section of the intake duct is not constant in its shape, which can induce losses and cause a decrease in the performance of the combustion engine.
  • the document FR-2548731 proposes to place a housing-shaped distribution case with a filter, directly on the cylinder heads. This integration makes it possible to obtain an effective mixture of the exhaust gases with the combustion air, the duct Exhaust keeps a complex shape that clutters the engine compartment and does not optimize the space.
  • Another example of arrangement of an intake duct of an engine is given in the document US 2003/217740 .
  • the present invention aims to overcome the disadvantages associated with this type of architecture by proposing a new implementation of the air intake duct which reduces the pressure drop while ensuring the tightness of the distribution.
  • the present invention proposes that the intermediate portion of the intake duct be integrated into the motor distribution casing.
  • the figure 1 is a general layout diagram of an internal combustion engine and highlights the path of the air supplying the V-motor.
  • the air passes firstly through an air filter 6 on which is
  • the air is then sent to a turbocharger 5 via an upstream pipe 9.
  • a turbocharger 5 Once compressed, the air is conveyed by an outlet pipe of the compressor 8 to a cooler.
  • Supercharged air cooler 11 is for example a conventional heat exchanger consisting of a bundle of tubes for exchanging energy between the compressed air and the outside air flowing between the tubes.
  • an intake duct orients the flow of air towards a switchbox and then to the air intake manifolds 16 of the front and rear benches of the combustion engine .
  • This intake distributor is composed of an upstream portion 12, an intermediate portion 19 and a downstream portion 2.
  • the upstream portion 12 is positioned between the outlet of the supercharged air cooler 11 and the intermediate portion 19 , which connects the upstream portion 12 to the downstream portion 2.
  • the latter makes it possible to direct the flow of compressed air to an air cutoff box 3, itself connected to the intake distributor 16.
  • the downstream portion 2 and the air shutoff housing 3 are located between the respective yokes of the front and back benches 4, as shown in the perspective view of the figure 2 .
  • the Figures 2 and 3 represent the arrangement of the distribution casings of the internal combustion engine V.
  • a first distribution casing 1 is secured to the cylinder head of the rear bench 4.
  • a second casing 15 is positioned on the engine cylinder block and comprises faces in contact with the other two casings 1 and 13.
  • the third casing 13, as shown in perspective on the figure 4 comprises the intermediate portion 19 and is fixed to the breech block of the front bench 10.
  • the intermediate portion 19 of the intake duct is integrated into the casing of the casing 13, which is mounted screwed on the breech block.
  • the intermediate portion 19 integrated in the casing 13 comprises ends at its ends for receiving the coupling means with the upstream and downstream portions.
  • these coupling means can be made by snap-fastening, collar, flange or even V-band.
  • the fact that the intermediate portion 19 is derived from the foundry being directly included on the housing 13, provides an air intake duct whose implementation in the engine block is less tortuous than the prior art.
  • the section of the intake duct is constant over its length, which reduces the pressure losses and the engine consumption.
  • the present invention is more compact than an air hose separated from the housing, which supports an additional function.
  • the casing 13 may also include fixing brackets intended to receive the fixing means of a motor cap 14.
  • This motor cap 14 is fixed on either side of the breech block on the mounting brackets respectively positioned on the casings 1 and 13.
  • the casing 13 thus allows to integrate several functions in one piece. This integration aims to improve the architecture of the engine block, increase the performance in terms of consumption and reduce the number of parts.
