  • WO 91/02145 A describes such a rotary piston engine according to the preamble of claim 1.
  • the disadvantages are incomplete fuel combustion and harmful emissions. To extend the mixture preparation and combustion of available time often takes place Mixing the fuel with air in a carburetor, well ahead of it Combustion chamber, or - in the case of fuel injection - in the intake duct.
  • the invention is therefore based on the object of a rotary piston engine to develop, which has the advantages of a miniature motor, so one permits the most complete possible fuel combustion and emissions harmful emissions reduced.
  • the mixture preparation is thus temporally and spatially separated from the processes previously common in internal combustion engines by a "processing cycle" is created.
  • a "processing cycle” is created with a Arrangement of successively working combustion chambers in one Rotary pistons.
  • the compressed medium is also in a rotary piston provided combustion chamber pressed, the following for the The "processing cycle” mentioned above remains closed.
  • the necessary pressure for the subsequent working stroke comes from the in the rotary piston leading combustion chamber, in which the entire The preparation process and the combustion have just been completed.
  • the combustion chambers provided in the rotary piston arrive successively via channels formed in the motor housing Working volumes in connection formed by the interdental spaces are.
  • any fuels especially hydrogen or alcohol, or Fuel mixtures such as Naphtha with water.
  • Fuel mixtures such as Naphtha with water.
  • the through holes forming the combustion chambers with Catalysts or inserts equipped for flameless combustion are.
  • hydrogen water injection can be used be worked while settling on a naphtha / water mixture Nickel insert is suitable.
  • the rotary piston engine according to the invention is not only suitable as Airplane, ship or car engine but also for electricity generators.
  • the Intake opening the opposite exhaust opening over a partial angular width covered. It is also advantageous if the Intake opening over the angular width of more than one Interdental space extends.
  • Figure 1 shows a schematic representation with the omission of a Housing cover the rotating parts of a rotary piston engine with internal combustion.
  • the output of the motor is designed as an internal gear 1 Rotating piston formed, which also has an external toothing 2 for Rotation of one downstream of the engine, in the drawing Gear not shown.

In this housing part 3 incisions 5 are provided, each with a an external toothing 6 provided rotary piston 7 is used, the has a smaller diameter than the internal gear 1, all Rotary pistons with the internal gear 1 are each in meshing 8 and with their axes of rotation 9 in the approximately through the housing part shown 3 formed diameter plane of symmetry of the internal gear 1. Each of these axes of rotation 9 is thus perpendicular to the axis 4 of the Internal gear 1.
  • the inner teeth 10 of the internal gear 1 and the outer teeth 11 of the Rotary pistons 7 are each set at 45 °, show slightly helical flanks and form each Single pistons, the rotation of the rotary pistons 1, 7 in the Interdental spaces 12 of the respectively assigned rotary piston slide immerse, which exactly the shape of the inner and outer teeth 10, 11th have the corresponding inner contour and preparation or Form compression chambers.
  • the tooth flanks are over their respective radial height straight, but somewhat helical in the axial direction twisted trained.
  • Each tooth 10, 11 is provided in the rotary piston 1, 7, one Combustion chamber forming through hole 13 associated with the the opposite rotary piston circular surfaces 1a, 7a opens out and here from opposite one another, a rotary piston 1, 7 sandwiched between enclosing housing walls 14, 15 or 16, 17 sealing over a certain angle of rotation range is kept closed (see e.g. Figure 2).
  • a rotary piston 1, 7 sandwiched between enclosing housing walls 14, 15 or 16, 17 sealing over a certain angle of rotation range is kept closed (see e.g. Figure 2).
  • only with regard to the course of the through hole 13 modified embodiment connects the inclined fürgangsborhung 13 a tooth space 12 with each second subsequent interdental space.
  • each tooth engagement 8 is in the housing walls 14, 16 for the in the rotary pistons 1, 7 shown in Figures 2 to 9 each have a first Connection channel 18 is provided, which rotates past it Interdental space 12 with a through hole 13 fluidly connects and this with compressed air or compressed fuel mixture fills.
  • a second connecting channel 19 is provided, which the past him rotating through bore 13 with one of the following Interdental spaces 12 fluidly connects, into which the Filling of the through hole 13 expands.
  • an exhaust opening 20 is provided, which in the housing walls 15, 17 each with a (in the drawing not shown) connected air or fuel mixture supply Suction port 21 is opposite so that the exhaust port 20 and assigned suction opening 21 one after the other with the past rotating tooth space 12 fluidically connected become.
  • the suction opening 21 can be the opposite one Cover exhaust opening 20 over only a partial angular range a.
  • the Intake opening 21 extends over the angular width b two successive interdental spaces 12.
  • Figure 2 for the interdental space located in front of the tooth engagement 8 Compression 3/4 and for those just emerging from the tooth mesh 8 Interdental space indicates 1/4 work.
  • Figure 4 shows for the lower one Interdental space the end of compaction and for the upper one Interdental space 2/4 work.
  • Figure 6 results for the lower subsequent tooth space a compression of 1/4 and for the upper interdental space a work of 3/4; in the case of FIG. 8
  • the following cycle shown takes place in the lower interdental space Compression of 2/4, while for the upper, completely from the Tooth engagement area emerged between the teeth the end of work is specified.
  • the workflow is therefore carried out in a modified 5-stroke process 1st bar Exhaust 2nd bar Intake (exhaust and intake - as with a two-stroke engine - can be done dynamically in one process) 3rd bar compression 4 tact Evaporation (mixture preparation and combustion initiation) 5th bar Job.
  • Compressed air or a compressed fuel mixture according to the invention valve-less via a "window” (first connecting channel 18) pressed into a rotating combustion chamber (through hole 13), where the processed fuel mixture burned and then valveless again via a “window” (second connecting channel 19) rotating working volume (interdental space 12) is shifted. there can initiate the combustion without or with the help of ignition or Glow plugs are made.
