Definitions

  • the present invention relates to the protection of ramps fuel supply of internal combustion engine against shocks, in particular in case of frontal deformation of the engine block.
  • the link flange of the intake manifold is made of plastic.
  • a solution simple to ensure the protection of the feeding ramps of fuel, is to replace the plastic flange with a aluminum flange, so as to have a shim metal protection.
  • the hold is rigid, it fully transmits shocks, without possibility damping by deformation.
  • any rigid screen fixed on the motor independently of the intake manifold presents the same disadvantage of transmitting to it the essence of the shock received.
  • such a screen is generally difficult to implement in the engine compartment, for reasons of space.
  • the present invention aims to ensure in better conditions, the protection of a fuel supply ramp in the event of a frontal impact of the vehicle.
  • a protection device composed of a deformable assembly by crushing fixed on the cylinder head, and a reinforcement stand fixed on the one hand on this set, and secondly on the cylinder block.
  • this device comprises at least one pillar crashing gradually in case of shock and oriented in the direction of the splitter fixing screws intake on the cylinder head.
  • the proposed protective device is indeed composed a deformable assembly by crushing fixed on the cylinder head 7, and the reinforcement stand 4, fixed on the one hand on this together, and secondly on the cylinder block 8.
  • the deformable assembly is constituted by sheet 1 and by 2.
  • the plate 1 is screwed preferably on the cylinder head 7 by the screws 5, and the stand 4 is screwed preferably on the cylinder block 8 and on the plate 1, by the screws 6.
  • the columns 2, here four in number, are reported on the sheet 1, preferably by welding. Their function is to crash gradually in case of shock. They are oriented in the direction of the fixing screws 10 of the intake distributor 9 on the cylinder head 7.
  • the plate 1 is arranged in front of the ramp 11, so as to be protected by the whole of the device in the event of a frontal impact.
  • the rigidity of the columns 2 is reinforced by the reinforcements 4, screwed both on each pillar 2, and on the 1.
  • the reinforcements 4 screwed both on each pillar 2, and on the 1.
  • the protective device proposed by the invention which "encapsulates" the feed ramp of fuel on the intake side of the engine, allows the protection of this ramp during a frontal deformation of the engine compartment, by progressive crushing of columns. This crash is controlled by the choice of optimal dimensions for the balusters, which can be carried out through recommendation calculations.
