Definitions

  • the invention relates to an exhaust gas collecting container for an internal combustion engine charged by means of a gas dynamic pressure wave machine.
  • Such an exhaust gas collector serves on the one hand to summarize the exhaust gas mass flows which are emitted by the individual cylinders of an engine.
  • an exhaust gas receiver weakens the pulsations caused by the engine. This weakening effect is of particular importance when an engine is being charged by a gas dynamic pressure wave machine. Excessive exhaust gas pulsations can severely impair the charging process in the pressure wave machine because they lead to fluctuations in the wave travel times.
  • CH-IS 378 595 or to the applicant's document CH-T 123 143.
  • the choice of the volume of an exhaust gas recuperator is always a compromise. On the one hand a large volume is advantageous because the weakening of the pulaations increases with increasing volume.
  • the invention seeks to remedy this.
  • the invention as defined in the claims is based on the object To improve the effectiveness of a small exhaust gas collector, in particular in internal combustion engines with a low number of cylinders and / or a weak degree of charging.
  • the advantage of the invention can be seen in the fact that by improving the spring action by means of mechanical spring means, the volume of the collecting container can be kept small.
  • the exhaust gas collection container essentially consists of an inner chamber 1 through which the gas flows and an outer sound shield 2.
  • the inflow ducts 6 ', 6 "from the cylinders and the outflow duct 7 to the pressure wave machine are shown in very simplified form.
  • the mechanical spring means are a corrugated spring steel membrane 3 ', which extends over the entire active length of the container and is clamped on the end faces. The clamping is gas-tight.
  • the membrane 3' runs between the flow-limiting wall 4 of the chamber 1 and the sound shield 2 and forms the latter a dead volume 5.
  • the basic idea is now to keep the total volume of the collecting container as small as possible due to the measure of increasing the spring effect of the container contents.
  • the quasi-stationary continuity equation is where V R is the container volume and f is the gas density in the container.
  • the flow-limiting walls 4 are formed by the resilient means themselves. These are spring steel sheets 3 ", which are clamped on the entry side of the collecting container. On the exit side, the sheet ends graze past the end of the container with little play, which is curved accordingly. Leakages due to play that flow around the spring plate into the dead volume 5 , cause only insignificant interference due to the relatively high pulsation frequency.
