Definitions

  • the technics disposes of internal combustion engine as: gas turbine, pistone engine ( Otto or Diesel) and rotating engine ( Wankel ).
  • Figures, 1 through 7 represent the working strokes of the engine. By these crossing sections, the shape proposed is the preferred design, but it could also be a different one.
  • the engine we are talking about can have one or more stages connected between each other.
  • FIG 1 shows a schematic crossing section where the ring 15 is static and his internal surfaces is shaped and the central rotor 10 runs around the axis 6.
  • the couple of blades 12 and 13 have a radial motion inside the rotor and the end seal of blades describe the internal shape of the ring 15 during rotation.
  • the blades are pushed to contact the internal shape of the ring 15 by a radial pressure.
  • the pressure can be: pneumatic, hydraulics, mechanical or of a different kind.
  • centrifugal thrust could be sufficient to ensure the sealing of blades to the profile of ring 15 without requiring any additional pressure.
  • the number of blades is not binding, it fixes the shape of the inner ring surface which permits the working strokes of the engine.
  • the working strokes of the engine are: inlet, compression, firing and exhaust.
  • the figure 2 shows the beginning of the inlet stroke (see arrow F).
  • the exhaust hole is sealed from the inlet hole by a seal 17 which is loaded on the rotor by the spring 18. Any different energy may be employed.
  • the inlet of gases is realized during the rotation of the rotor 10 in direction of arrow F .
  • the volume variation is defined by the external diameter of rotor, by the internal profile of ring 15 and the left lateral surface of blade 12.
  • the inlet holes and the exhaust holes could have a different arrangement.
  • the figure 3 shows the inleted gases at the end of inlet stroke (see arrow A).
  • the arrow B shows the gases during the compression stroke between the blade 13P and the blade showed by arrow C.
  • the figure 4 shows the volumetric change during the most difficult position of the compression stroke.
  • thermic level raises as much as the pressure and the absorbtion of thermal energy increases.
  • the figure 5 shows the compressed gases when the firing stroke starts.
  • the fired gases energy produces a pressure, inside the combustion chamber, constraining the surface S of the blade 12P to rotate around the axis 6 and to slip along the internal profile of the static ring 15.
  • the figure 7 shows the end of the exhaust of burned gases. To eliminate the burned gases as much as possible, an additional little duct connected to the exhaust hole has been designed. It can be seen on the figure 1.
  • the seal 17 insures the separation of the inlet hole by the exhaust hole.
  • the power attachement (the power shaft) is on the central rotor 10 and comes out from the flanges of the external seals coupled to the static ring 15 surfaces.
  • Any kind of fuel can be used for this engine: gasoline, fuel oil, gas, petroil, etc.
  • the ignition system may have a coil ignition, electronic ignition, or a different one.
  • the cooling system can be with:
  • the engine Using cooling liquid, the engine must be provided of internal ducts for the coolant.
  • the engine In case of air cooling system, the engine must be provided of cooling ribs.
  • the engine must be provided of a suitable lubricating system to allows parts to move one on each other freely without friction.
  • the engine must have a complete set of accessories to rum in complete autonomy.
  • the output power is 1/30 of the power calculated as the maximum pressure, during firing stroke on the piston surface, was on during the complete cycle (inlet, compression, firing, exhaust) and with the maximum torque lenght, refereted to the crankshaft.
  • weight/power ratio that can be as low as 0.2, similar to the aviation gas turbine ratio.
