Definitions

  • the present invention relates to a gas dynamic pressure wave machine according to the preamble of independent claim.
  • Pressure wave machine is known from the prior art for example from CH-A-681 738.
  • the standard pressure wave machine is for high boost pressures and good efficiencies strongly dependent on filling. At deep Internal combustion engine throughput decreases the filling in the rotor Pressure wave machine and thus also the boost pressure. The The machine is actually too big in this map area. With a high internal combustion engine throughput, the filling increases strongly and the compression efficiency deteriorates yourself. The pressure wave machine is in this map area actually too small.
  • FIG. 1 For the sake of simplicity, the processing according to FIG. 1 a pressure wave cycle is shown and described while a two-cycle machine is shown in FIGS is.
  • the invention is based on the number of pressure wave cycles regardless, it can be used for pressure wave machines with only one cycle or with two or more cycles become.
  • Figure 1 shows a development of the rotor Pressure wave machine according to the prior art and you can see the internal combustion engine 1, the gas dynamic Pressure wave machine 2, the high pressure exhaust duct 3 and Low-pressure exhaust duct 4 including the purge air S, the rotor 6 with the individual cells 18, the fresh air inlet 8, or low-pressure fresh air supply duct 14, the high-pressure charge air duct 10, which merges into the charge air duct 11 and leads to the internal combustion engine 1.
  • FIG. 2 and 3 is an inventive Gas dynamic pressure wave machine shown on the one Plenty of improvements have been made to to increase the overall efficiency significantly.
  • the Pressure wave machine 30 is via the high-pressure exhaust duct 31 and the high pressure charge air duct 32 with the schematic shown internal combustion engine 33 connected.
  • in the Gas housing 34 is also the low pressure exhaust duct 35, and it can be seen from this figure that the two channels, d. H. the high pressure exhaust duct and the Low-pressure exhaust duct, in the gas housing on the rotor side as sector-shaped openings, each with an opening edge 36, or 37 lead.
  • the rotor 40 can also be seen with its Cells 41, the rotor being arranged in a jacket 42 and driven, for example, by a belt drive 43 becomes.
  • the pressure wave machine is an open system, and that means that between the exhaust part and the Fresh air section a direct connection via the rotor consists. This also causes the engine pressure pulsations from the exhaust gas high pressure section to the fresh air high pressure section transfer.
  • the connecting line 46, the High-pressure charge air duct 32 into the high-pressure exhaust duct 31 leads.
  • the connecting line contains a Check valve 47, optionally with a electronic control is provided. It works Check valve as a regulation in the sense that only Pressure surges are transmitted, their energetic level is higher than the current pressure in the high-pressure exhaust duct.
  • the negative pressure pulses i. H.
  • Branch that in Figure 2 or 3 somewhere between the High pressure charge air duct edge and the engine intake is arranged, directly after the opening edge of the high-pressure charge air duct is arranged.
  • This variant is the Not shown for clarity.
  • the pressure wave machine is after State of the art heavily dependent on filling.
  • Reduction of pressure pulsations as described above allows the provision of a connecting line Return of charge air to the high-pressure exhaust side of the Pressure wave machine, thereby increasing the Mass throughput of the machine and thus an increase in Filling levels, which results in a significant increase in pressure noticeable.
  • An additional regulation of the returned Fresh air high pressure volume by means of the regulated Check valve can therefore be used to control the charge pressure in the general and in addition to the Otto engine Power control can be used.
  • the pressure wave machine to improve compression efficiency at higher Engine throughputs can be dimensioned somewhat larger, without increasing the boost pressure at lower engine throughputs to lose.
  • This can also be done, for example, by that the cross section of the connecting channel by means of a suitable, known device is regulated, wherein either the regulated check valve or one additional cross-sectional control can be used. This is particularly effective in the lower to middle Speed, temperature and load range of the Internal combustion engine.
