Definitions

  • the invention relates to a rotary piston engine that deals with a combustible supplied under low pressure Can operate gas / oxygen mixture.
  • the second valve has the advantage of being a larger one Volume can flow in faster. This is for the Charging process of the combustion chamber is extremely important.
  • the engine according to the invention are in the Housing two counter-rotating preferably identically designed rotary pistons.
  • the two axes of rotation of the Rotary pistons are parallel to each other.
  • the design of the two rotary pistons is such that the two opposite circumferential areas or axially extending circumferential lines of the rotary pistons always in have substantially the same distance from each other.
  • the same also applies to the housing wall against - overlying circumferential areas or lines of the two pistons
  • this area of the peripheral surfaces of the Rotary piston essentially the same distance to Housing on.
  • the two rotary pistons are inside the housing of the Motor arranged between the inlet and the outlet. She So divide the housing into two parts, being the inlet and shield the outlet from each other.
  • Hydrogen and oxygen are preferred as fuel used, which separated the interior of the housing via the inlet be fed.
  • a particular advantage is building one Mono gas column for isolating the valves from the combustion chamber. Since the valves are now in the area where there is no reaction partner is present, they are only slightly warmed. she remain functional.
  • actio reactio is also to be understood essentially why the previous rotary piston engines had to be operated with little efficiency without valves.
  • the new concept of the rotary piston engine has one automatic closing of the supply line after ignition.
  • Closure lies behind a gas column with no reactants remains well below the temperature of the combustion chamber, so that the valves can operate in a temperature range in that they don't lose their function.
  • the engine only sucks fuel again when the combustion chamber pressure comes below the pressure of the supply line. This is not clocked as with the Otto engine, but only depends on the volume of the rotary pistons (see Fig. 8 (A) - (C) and Fig. 9. It is important that the fuel supply is not interrupted, that a lot of time elapses until the next ignition, and that all of the energy is obtained for rotational work.
  • the scooping volume V s is to be used, which performs the pressure reduction (see Fig. 8 (A) - (C) and Fig. 9).
  • the initial volume V 1 is 40 [cm] 3 .
  • the expanded volume V 2 is 60 [cm] 3 .
  • the scoop volume V s 20 [cm] 3 .
  • a working cycle is half a turn of a piston. So two work cycles are a full turn.
  • the inlet valve opens automatically, not clocked when the supply pressure is 1 [bar].
  • the supply pressure is natural adjustable and can therefore be higher, which leads to a leads to higher working pressure.
  • the pV diagram for the above Description is shown in Fig.7.
  • the opposite ones Area areas or line areas of the rotary pistons as well the opposite surface or line areas between the rotary piston and the housing inner wall one each constant distance.
  • For the operation of the Motor according to the invention is therefore not a disadvantage if the rotary pistons rotate in the housing without contact. But this results in the very crucial practical The advantage that there is no need for lubrication.
  • the wave is hollow for that designed.
  • the inside of the shaft is conically hollow, so that injected cooling water due to the centrifugal force over the sloping surface flows outwards,
  • Fig.4 shows a horizontal section through the engine with the Gears of the piston coupling and the gear.
  • Figure 5 shows the detail "X".
  • the spring shown here is constructed as an "oscillating lock". For the time of low pressure, it lets through H 2 and O 2 . After ignition, it automatically closes the backflow of the gas mixture at a higher pressure. The energy converted into pressure can be converted into rotational energy.
  • Figure 6 shows the detail "B".
  • the closure shown here is one Alternative to Fig.5, which is in the test.
  • the effort to manufacture is larger, but it could be that the closure is more effective. Accelerated loading of the combustion chamber is too expect.
  • Fig. 7 shows the pV diagram with and without water spray
  • Fig. 8 (A) to (C) the pressure behavior in the combustion chamber.
  • the Graphs show the pressure as a function of the scooping volume and the inlet pressure. The valves only open when the pressure in the combustion chamber decreases under the pressure of the supply line. Then the combustion chamber is reloaded.
  • FIG. 10 shows the arrangement for spark ignition by a heating coil or a LASER. The same applies here: the ignition mechanism does not have to be clocked.
  • FIG. 1a A) to (F) each show in cross section a rotary piston motor 10, the two rotary pistons 14, 16 of which are rotatable in a housing 12 are shown in different rotational positions.
  • the housing 12 is provided with an inlet 18 and an outlet 20 opposite this.
  • Two separate lines 22, 24 for light hydrogen (LH 2 ) and air-oxygen (O 2 ) lead into the interior of the housing 12 via the inlet 18.
  • LH 2 light hydrogen
  • O 2 air-oxygen
  • These "fuels” also other fuels
  • the engine is rotated as usual via a starter he H 2 , which reacts immediately when the ignition is switched on.
  • a small pressure vessel designed as required which is supplied with reserve pressure (max. pressure) of each gas type via a diaphragm pump operated by the motor, can supply the required pressure (vernacular ,, To give gas"). Unlike conventional combustion engines, this is not fuel injection.
  • the two rotary pistons 14, 16 are of identical design and each have a symmetrical shape.
  • the outer contour of the two rotary pistons 14, 16 are constructed from a polygon and short arcs.
  • the pressure then causes the rotary piston 14 to be set in rotation in the direction of the arrow shown;
  • the rotary piston 16 is also set in rotary motion by coupling the two pistons.
  • the rotary piston 16 would not experience any rotary movement on its own, since the sum of all of the rotary piston 16 due to the pressure increase in the Torque acting combustion chamber is zero. However, this does not apply to the rotary piston 14, which is why it is driven in rotation.
  • the housing 12 itself is provided with a plurality of cooling channels 34 for cooling with a cooling medium, in particular water.
  • the bearings 32 are also provided with cooling channels 34, so that the heat transfer via the axes of rotation 26 can be dissipated quickly from the housing 12 via the cooling.
  • One of the axes of rotation 26 of both rotary pistons 14, 16 forms the drive shaft of the motor 10, the rotation of which is implemented in a gear 36.
