Definitions

  • the present invention relates to an exhausting system construction, specifically designed for motorcycles and the like.
  • motorcycle exhausting systems conventionally comprise one or more end-pieces comprising the silencer device, and being associated with a manifold coupled to the engine exhausting means.
  • Cylindric catalytic end-pieces are very expensive and, likewise to existing catalytic systems, they must be periodically replaced, as the catalyzer effect has been exhausted.
  • the aim of the present invention is to provide such an exhausting system construction to be used in motorcycles and the like, overcoming the above mentioned drawbacks of the prior art.
  • a main object of the invention is to provide such an exhausting system construction which can be used for a very broad range of exhausting systems, included those which are already existing on the market.
  • Another object of the present invention is to provide such an exhausting system construction which allows to restore the catalytic system, with a low cost.
  • an exhausting system construction particularly for motorcycles and the like, characterized in that it comprises a catalytic element which can be removably arranged between an exhausting manifold and a silencer device.
  • the exhausting system construction according to the present invention which has been generally indicated by the reference number 1, comprises, as main components thereof, a catalytic element 2, which can be removably arranged between an exhausting manifold 3 and a silencer device 4.
  • the catalytic element 2 comprises a substantially cylindric body, including a plurality of concentric chambers, and having walls coated by a catalyzer, of a per-se known type.
  • the catalytic element 2 can be arranged at a cylindric end portion 5 of an exhausting manifold 3, which can be in turn engaged in an inlet bottom element 6 of the silencer device 4.
  • Said silencer device 4 may be of any per se known type, and comprises an outer casing 7, coupled, at an end portion thereof, to the inlet bottom element 6 and, at the other end portion thereof, to an outlet bottom element 8.
  • Said inlet 6 and outlet 8 bottom elements operate as a support for a core element 10 comprising a perforated tube, ending with an unperforated outlet portion 11.
  • the core element 10 is locked by a locking rivet 12, coupling the outlet bottom 8 to the outlet portion 11 of said core element 10.
  • a sound absorbing material 9 such as a glass wool material, is arranged between said core element 10 and outer casing 7.
  • the silencer device 4 is locked on the manifold 3 by locking means comprising, in this embodiment, pulling spring elements 13, having end portions attached to suitable attachment means 14 which are respectively welded on the manifold 3 and inlet bottom element 6 of the silencer device 4.
  • FIGs 3 and 4 show an exhausting system construction 101, fully analogous to the exhausting system construction 1 shown in figures 1 and 2, but including different locking means for locking the silencer device 4 on the manifold 3.
  • Said locking means comprise, in this embodiment, screws or rivets 113 designed for clamping therebetween bracket elements 114 respectively associated with the manifold 3 and the inlet bottom element 6 of the silencer device 4.
  • Figures 5 and 6 show an exhausting system construction 201, fully analogous to the construction 1 and 101 shown in the preceding figures, but including a probe element 215 which is an useful element for the operation of the electronic injection system.
  • the invention provides a motorcycle exhausting system construction allowing to fit exhausting system with either one or more silenced end-pieces, independent from the catalyzer device.
  • the modular structure of the subject exhausting system construction provides a lot of functional advantages.
  • Another advantage is that, in a case of a damaging of the end-piece, for example occurring in a road accident, said end-piece, which does not comprise the catalyzer proper, can be replaced in a manner which is much more unexpensive than the replacement of a conventional catalyzed exhausting end-piece.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.
