    • F01N13/16—Selection of particular materials

Definitions

  • the invention relates to a silencer for exhaust systems of motor vehicles, especially passenger and Trucks and buses, with a housing that one and can be connected on the outlet side to pipes of the exhaust system is, and functional elements that are inside the housing are included.
  • the invention has for its object a silencer for exhaust systems of motor vehicles to create the one hand is reduced in weight and on the other hand better than known from the prior art Silencers can be recycled, being beyond its corrosion resistance and impact resistance and its other thermal and mechanical properties all requirements in the operation of the motor vehicle have to suffice.
  • the Housing of the silencer made of a glass fiber reinforced and heat-stabilized polyphthalamide (PPA) is formed.
  • PPA polyphthalamide
  • Such a design of the silencer can Housing of the silencer can be easily recycled, the same procedures can be used as they do for bumpers made of appropriate materials are common.
  • polyphthalamide for the housing of a Silencer has proven to be a polyphthalamide (PPA) which contains 45% by mass of reinforcing glass fibers.
  • the material can be used as polyphthalamide (PPA) "AMODEL AS-1145 HS” from Amoco Polymers, Inc., Alpharetta, Georgia 30202, USA.
  • PPA polyphthalamide
  • AMODEL AS-1145 HS Amoco Polymers, Inc., Alpharetta, Georgia 30202, USA.
  • this additional thermal insulation layer preferably can be formed from rock wool.
  • the housing made of the said polyphthalamide can expediently into a central section and two end sections structure, depending on the requirement profile, which any given by the exhaust system Design of the end sections is possible and one Basic shape of a middle section can be used.
  • the end sections of the housing can each muffler a receptacle for an input or output side Train the exhaust system pipe.
  • At least one of these receiving ports is arranged eccentrically.
  • both receptacles can also be arranged eccentrically.
  • Embodiments of the silencer according to the invention realized be in which at least one end portion of the housing forms a double intake port in which two one or exhaust pipes on the outlet side can be accommodated are.
  • both end sections can also train such a double intake port.
  • cross section of the housing of the invention Different designs are possible, such a cross section round, approximately oval or can be configured appropriately in another way.
  • This heat and squeeze ring can preferably be made of Teflon be trained.
  • the functional elements accommodated within the housing The silencer can be used in a state of the art be known manner, all of known in the art suitable for silencers Functional elements can be used.
  • a first embodiment shown in Figure 1 of an inventive Silencer 1 is used for installation in exhaust systems of motor vehicles, it being the motor vehicles both for cars and trucks and also for buses or the like. Special vehicles can act.
  • the silencer 1 shown in Figure 1 has a housing 2, in which the usual functional elements for silencers are included.
  • the housing 2 is divided into that shown in Figure 1 Embodiment of the silencer 1 in a central section 3 and two adjoining the central section 3 on both sides End sections 4, 5.
  • the left end portion 4 in FIG. 1 forms a receptacle 6 in which the silencer 1 facing end of a pipeline 7 not otherwise Exhaust system shown is added.
  • the right or output end portion 5 of the Silencer 1 forms a receptacle 8 in which the end facing the muffler 1 on the output side of the silencer 1 arranged pipeline 9 the exhaust system, not shown in the rest is.
  • the housing 2 of the silencer 1 is made of a glass fiber reinforced and heat or heat stabilized polyphthalamide (PPA) trained. This contains polyphthalamide (PPA) too 45% by mass of reinforcing glass fibers.
  • the material can preferably be such a polyphthalamide (PPA) "AMODEL AS-1145HS” from Amoco Polymers, Inc., Alpharetta, Georgia 30202, USA.
  • PPA polyphthalamide
  • AMODEL AS-1145HS polyphthalamide
  • This material is a glass fiber reinforced heat-stabilized engineering plastic, the one high heat resistance, a high flexural modulus and a has great tensile strength and is also characterized by excellent Creep resistance and low moisture absorption distinguished.
  • Its tensile strength is 259 MPa, its elongation at break 2.6%, its flexural strength 362 MPa, its flexural modulus 13600 MPa, its shear strength 108 MPa, its compressive strength 314 MPa, its Poisson number 0.41, its Izod impact strength at 3.2 mm 133 J / m, its Izod impact strength 12.9 kJ / m 2 , its Izod impact strength 72.5 kJ / m 2 , its Charpy impact strength 14.8 kJ / m 2 , its Charpy impact strength 81.2 kJ / m 2 and its Rockwell hardness 125 R.
  • the housing can be used to further limit the temperature load 2 have an additional thermal insulation layer, the can preferably be formed from rock wool.
  • Silencers are the intake port on the inlet side 6 and the outlet-side receptacle 8 of the respective End sections 4, 5 arranged eccentrically.
  • FIG. 2 differs from this of the silencer 1 according to the invention, in which both the input-side intake port 6 and the output-side receptacle 8 centrally with respect to the End sections 4, 5 are arranged.
  • Silencer 1 forms the input side End section 4 of the muffler 1 an external intake port 6, whereas the output end section 5 of the silencer 1 has a concentric receptacle 8 formed.
  • Silencer 1 forms both the input side End section 4 and the end section on the output side 5 from a double intake port 10 or 11, in which two ends of one with respect to the silencer 1 on the input side Pipe system 12 or output-side pipe system 13 are included.
  • the embodiment shown in Figure 5 of the silencer 1 according to the invention has an input side End section 4 with a central receptacle 6, whereas the output-side end section 5 has a double receptacle 11 trains, in which two ends one with respect on the silencer 1 on the outlet pipe system 13 are supported.
  • Figures 7 and 9 is one with several rounded and straight cross-section of the silencer 1 provided, the embodiment according to FIG has single receiving nozzle 6, whereas the embodiment 9 has a double intake port 10.
  • Figure 10 of the muffler according to the invention has a circular Cross-section, with a centrally arranged receptacle 6 is provided.
