Definitions

  • the present invention relates to a motor with internal combustion comprising at least one pinion comprising a central fixing hole and a plurality of branches connecting the hole to the peripheral toothing line around which a timing belt and a pump comprising an output shaft of which the end is threaded, said pump being attached to one side of a mounting housing comprising two holes tapped by at least two screw and threaded end of the output shaft being fixed in the central hole of the pinion by a nut on the other side of the fixing housing
  • It relates more particularly to a motor of this type in which the pump is a injection pump.
  • the intervention time for such operation was estimated to take several hours, from around 2 to 3 hours.
  • the object of the invention is then to propose an internal combustion engine fitted with a pump whose change, in case of failure, either less expensive.
  • the invention relates to a internal combustion engine comprising at least a pinion including a central fixing hole and a plurality of branches connecting the hole to the peripheral toothing line around which is fitted with a strap distribution, and a pump comprising an axis of outlet whose end is threaded, said pump being fixed to one face of a housing fixing comprising two threaded holes with au minus two screws and the threaded end of the axle outlet being fixed in the central hole of the pinion by a nut on the other face of the casing fastening device characterized in that at least two sprocket branches are each pierced with a hole and in that the face of the fixing housing opposite the pinion includes two tapped holes suitable for fixing the pinion to the housing fixing before dismantling the pump.
  • the invention therefore consists in leaving the distribution set including in particular the pump gear and the drive belt distribution in place when changing the injection pump, as will be described by following in the process of the invention.
  • the tapped holes are adapted to receive the fixing screws of the pump on the fixing housing.
  • the tapped holes suitable for fixing the pinion to the housing fixing when the pump is disassembled are through and are the ones that go up the pump.
  • the pump is an injection pump fuel.
  • the invention also relates to a vehicle automobile comprising an engine as it comes to be described.
  • the invention relates to the application of process according to the invention for changes in combustion engine injection pumps internal defective.
  • FIG. 1 a motor with motor vehicle internal combustion 1 according to the state of the art comprising a set of distribution 2 in which a belt of distribution 21 drives a support pinion 22 of diesel injection pump 3.
  • This injection pump 3 is fixed on the rear face 4a of a support casing 4 and its threaded end 31 is mounted in the hole central of pinion 220 and is blocked by a fixing nut 42.
  • the fixing is carried out by means of three fixing screws 5 arranged at 120 ° on the same diameter by relative to the pump fixing center 3.
  • the pump support pinion 22 meanwhile, has a plurality of branches 221 which extend from central hole 220 to its line of straight toothing L which drives the belt distribution 21.
  • This disassembly then allows the disassembly of the faulty injection pump 3 by unscrewing the fixing screw 5 fixing holes 41 made in the rear face 4a of the casing support 4 and, on the other hand, the reassembly of a new 3 'injection pump by tightening the screw 5.
  • the disassembled timing belt 21 must also be changed because its reassembly would present risks of breakage too that could bring about change of the complete engine.
  • Timing belt 21 used and reassembly are obviously costly additional operations. Gold, "normal" wear of the drive belt distribution 21 does not require that these operations are performed.
  • the invention proposes to avoid dismantling of the distribution set and therefore of the associated timing belt.
  • These fixing holes are, in accordance with the invention, emerging from the front face 4b of the casing at the rear 4a.
  • the pinion 22 is then held by two screws fixing on the front face 4b of the casing support 4 while leaving the strap of distribution 21 in position.
  • the reassembly of a new pump 3 'injection can then be done by unscrewing a first screw of the front face 4b and of the pinion then introducing it into one of the holes fixing the pump 32 and screwing it back on the rear face 4a of the support 4.
  • Locking of the fixing nut 42 of the new 3 'pump can then be carried out and the unscrewing and re-screwing the last screw fixing can also be carried out according to the steps made for the first fixing screw 5.
  • the solution according to the invention allows, first of all, perform an injection pump exchange without have to touch the engine distribution.
  • the solution allows a downtime of the shorter vehicle and therefore to pay a bill well "light".
