Definitions

  • the invention relates to a suction system for internal combustion engines.
  • suction systems for weight reduction from relatively light materials and with relatively thin walls are sought.
  • An optimization of this goal is prevented by uncontrolled deflagrations of the fuel-air mixture in the intake systems when operating internal combustion engines. Pressures occurring with such deflagrations can damage the suction systems, which result in poor operating behavior of the internal combustion engine, increased consumption and an unfavorable exhaust gas composition.
  • the object of the invention is to equip a suction system in such a way that damage by excess pressure from a deflagration in the suction system is avoided.
  • Claim 2 describes a construction principle of a burst protection device which is advantageous with regard to freedom from maintenance and simple construction.
  • An essential for this construction principle lip-like sealing element which acts in the arrangement described in claim 2 as a pressure relief valve.
  • the sealing element acting as a pressure relief valve additionally serves to seal connection points of the intake system with the internal combustion engine and / or in a built-in intake system between its parts.
  • connection points as burst protection devices is advantageously achieved by spaced flanges, the mutual distance being achieved according to a partial feature of claim 4 by means of clamping bushes projecting over a flange surface for the bolts of the connection.
  • the sealing element bridging the gap between the flanges is permanently held and fixed in a groove in one of the flanges.
  • the suction system is preferably thin-walled in plastic.
  • An intake system 1 for a multi-cylinder internal combustion engine 2 comprises intake pipes 3, which are detachably connected to a common collector 4.
  • a throttle valve connector 5 is also releasably flanged to the collector 4.
  • Each intake manifold 3 has a flange 6 for detachable connection to the internal combustion engine 2.
  • the respective releasable connection of the suction pipes 3 to the collector 4 comprises flanges 7 and 8.
  • the flanges 7 and 8 are arranged at a mutual spacing when the screwing is effective. They thus form an opening 10 which is transverse to a line cross section 9 of the suction system or a suction pipe 3.
  • An elastic, lip-like sealing element 11 is arranged transversely to the gap-shaped opening 10 and is connected to a ring 12.
  • the ring 12 is held and fixed in a groove 13 arranged at a distance from the edge of the line cross section 9.
  • the lip-like sealing element 11 is designed and dimensioned such that, when the flanges 7 and 8 are screwed together effectively, they cooperate with the flat boundary 17 of the flange 8 in such a way that the sealing element 11 consists of a against the suction negative pressure sealing system by a bursting or excess pressure which arises in the event of a deflagration of a fuel-air mixture in the intake system 1, into a position 19 distant from the boundary 17 to form an outflow cross section 18.
  • the opening 10 and the sealing element 11 thus form a burst protection device 20.
  • burst protection devices 20 can also be arranged in the connection of the intake system 1 to the internal combustion engine 2 between the latter and the flanges 6 of the intake pipes 3 and in the flange connection of the collector 4 to the throttle valve connector 5.
  • the numerous burst protection devices 20, which additionally serve to seal the respective flange connection, make it possible to design the suction pipes 3 and the collector 4 of the suction system 1 with thin walls in plastic, and thus to achieve a suction system 1 which is considerably reduced in weight.
  • the lip-like sealing element 11 on the ring 12 in its main extent relative to the mounting direction of the flanges 7,8 directed radially outward.
  • the sealing element 11 is of asymmetrical cross section with a longer flank 21 facing the line cross section 9.
