Definitions

  • the invention relates to a rotary piston internal combustion engine according to the preamble of claim 1.
  • Such motors are well known.
  • the best-known embodiment is known under the name Wankel engine. From the DE 103 56 916 A1 It is known to generate space ignition in an internal combustion engine in a combustion chamber by means of microwave energy in order to better ignite and burn the combustion of the fuel introduced via a fuel-air mixture.
  • fuel is used in general, regardless of whether it is diesel, gasoline, hydrogen or another fuel suitable for operation.
  • fuel-gas mixtures are introduced into the combustion chamber.
  • an ignitable gasoline fuel-air mixture is compressed in the working chamber in a combustion chamber and caused to react / oxidize by a spark plug.
  • the spark plug forms a recess in the surface of the working chamber, so that this surface, which acts as a running surface for the edges of the rotary piston, has an unevenness which leads to a loss of compression.
  • the ignition causes the chemical oxidation to spread spherically from the location of the ignition in the form of a pressure and reaction front (laminar combustion chamber phase) in the elongated and flat combustion chamber and causes laminar combustion, which also leads to a loss of compression.
  • laminar combustion chamber phase laminar combustion chamber phase
  • DE 103 56 916 B3 discloses a method for igniting the combustion of a fuel in a combustion chamber of an engine by coupling microwave radiation generated in a microwave source outside the combustion chamber into the combustion chamber, whereby the energy input into the fuel in the combustion chamber distributes the combustion over a large volume in the combustion chamber and ignites it essentially simultaneously as well as an associated ignition device and an associated motor.
  • U.S. 5,845,480 A describes an ignition device for an internal combustion engine, consisting of a microwave energy source located outside the combustion chamber, which emits microwave energy into the combustion chamber, and an infrared laser energy source located outside the combustion chamber, which emits laser energy into the combustion chamber so that a plasma is generated in the combustion chamber, which the combustible mixture in the combustion chamber ignites.
  • the plasma is preferably a contactless plasma, which is generated in the free space within the combustion chamber, spatially separated from the combustion chamber wall structure, and is arranged spatially separated from the microwave transmitter.
  • the Microwave energy is emitted at a frequency within the resonance response of the combustion chamber.
  • a device for igniting fuels in an internal combustion engine which atomizes the fuel and introduces it into the combustion chamber by spraying, in order to be ionized and burned there by means of electromagnetic radiation generated outside the combustion chamber and connected by means of an emitter.
  • a magnetic field is created in the combustion chamber to improve the ionization of the fuel in the combustion chamber.
  • the invention is therefore based on the object of achieving an improved ignition of the fuel in the combustion chamber and an improvement in the efficiency.
  • At least one microwave window is arranged in the combustion chamber wall, on whose side facing away from the combustion chamber there is a device for coupling microwave energy in the form of microwaves into the combustion chamber of the working chamber.
  • a microwave window is understood to mean an area which is closed off from the outside and which is microwave-permeable.
  • the combustion chamber wall as part of the housing wall thus also serves as a running surface in the area of the combustion chamber.
  • a device for coupling in microwave energy is located on the side of the microwave window facing away from the combustion chamber.
  • the device for coupling in microwave energy can either comprise at least one microwave spark plug in a bore in the combustion chamber wall, which can be connected to a microwave pulse generator via a microwave waveguide, or a microwave pulse generator attached directly to the housing.
  • microwave energy By coupling in microwave energy, it is possible to ignite the fuel in the combustion chamber.
  • the local ignition is replaced by a room ignition or by a boundary layer ignition, the fuel being excited as homogeneously as possible over the entire volume of the combustion chamber before ignition, which takes place through an absorption of the microwave energy by the fuel particles distributed over the combustion chamber.
  • the absorption capacity of microwaves described by a material parameter tan ⁇ (t) and the associated penetration depth, play an important role.
  • the microwave energy is concentrated in a sufficient amount at as many points as possible in the combustion chamber in order to generate a room ignition in the combustion chamber there through a large number of ignition nuclei.
  • as little microwave energy as possible should be reflected back to a microwave source. The lower the reflection, the greater the absorption and thus the energy consumption of the fuel particles for a space ignition.
  • the combustion chamber wall is at least partially made of a microwave-permeable material that is particularly suitable for this, such as ceramic or sapphire glass.
  • a microwave-permeable material that is particularly suitable for this, such as ceramic or sapphire glass.
  • This can in particular also be a ceramic material, preferably with a purity of> 99%, or another solid material that is permeable to microwaves. This can be done in such a way that the combustion chamber wall either has individual areas made of this material or consists of the entire material and areas are formed therein by additional measures which allow the microwave energy to pass through and thus form the respective microwave window.
  • Uneven local geometric metallic structures are arranged in the combustion chamber wall which, depending on the configuration, deflect microwaves reflected from the combustion chamber back into the combustion chamber in a concentrated or scattered manner.
  • These local structures can either have a curved, uniform configuration, such as, for example, harmonic oscillation curves, for example a sinus curve, or an angular configuration. It is also possible to form the structures by bodies in the form of balls or the like. With these structures, a reflection or scattering of microwaves can be achieved in a targeted manner, so that in areas of the combustion chamber in which ignition of the fuel would normally not take place, the fuel can be regenerated and ignited by local field increases.
  • At least the combustion chamber wall is arranged without changing the running surface in the housing wall forming the working chamber without a recess, as in conventional engines.
  • This can be done in such a way that either only the combustion chamber wall is integrated into the housing wall or on the entire wall
  • the uneven local geometric structures are expediently designed in the form of particles introduced into the combustion chamber wall or as a metal powder layer.
  • ceramic material for example, this is applied to a pressed and pre-sintered carrier layer (green compact), whereby the unevenness can already be present or are only produced by known suitable shaping processes such as rolling, milling, etc. at this stage.
  • the surface prepared in this way can now be metallically vapor-deposited, doped with metal powder or treated in another known suitable manner in order to provide it with a metallic layer. Holes can then be created using a laser, etching or another common method, which then allow the passage of microwaves and serve as a microwave window. Then another layer that is microwave-permeable and made of a ceramic material or sapphire glass is applied.
  • a finished insert that can be introduced into the housing wall or also the piston wall can preferably be produced in this way, which insert can be secured against rotation by means of a form fit.
  • the combustion chamber wall is provided with a metallic layer extending in the longitudinal direction of the combustion chamber wall on the side facing away from the combustion chamber or inside the combustion chamber wall and having at least one opening for the passage of microwaves.
  • the metallic layer can be vapor-deposited on the outside, with corresponding openings being etched out depending on the application.
  • a metallic layer extending in the longitudinal direction of the combustion chamber wall is arranged, which has at least one opening for the passage of microwaves, similar to described above in connection with the local metallic structures.
  • this wall can be inserted, sprinkled, vapor-deposited and also sintered and fired.
  • the microwaves After being coupled into the combustion chamber, the microwaves are reflected by the metallic rotary piston and hit the metallic housing of the engine through the ceramic material of the combustion chamber wall and are thrown back towards the combustion chamber from there. Since the ceramic material also dampens the microwave, the metallic layers additionally introduced into the ceramic material can serve as a reflective surface that shortens the path through the ceramic material for the microwaves. Of course, these metallic surfaces have openings where the microwaves are coupled in.
  • the device for coupling in the microwaves has at least one microwave pulse generator attached to the housing, via which the microwaves are coupled into the combustion chamber.
  • a microwave pulse generator is in the EP 15170029.1 described.
  • the at least one attached microwave pulse generator is either located exactly at the respective location of the microwave window or it is distributed by means of a channel acting as a microwave waveguide in the housing wall.
  • the at least one microwave pulse generator is preferably attached in the axial direction so that the microwaves are introduced into the housing wall laterally, preferably parallel to a housing longitudinal axis.
  • the microwaves after being introduced into the housing wall of the first rotary piston internal combustion engine can also be coupled into the housing wall of the following rotary piston internal combustion engines are passed on to the respective combustion chamber.
  • At least one microwave channel running in the housing wall is expediently arranged, which is connected to at least one microwave window.
  • This microwave channel can be incorporated into the housing wall afterwards, e.g. by milling or other suitable measures, or even before the final sintering in a ceramic layer of the combustion chamber wall.
  • the surface of the at least one microwave channel can additionally be provided with a metallic layer, the metallic layer being interrupted at the points at which microwaves emerge from the microwave channel. In this way, the microwave energy can be brought into the combustion chamber in a targeted manner, since the microwaves oscillating in the microwave channel and reflected by the walls can exit through the at least one opening.
  • the microwave channel also has branches where appropriate.
  • the microwave channel can also be formed simply by the microwave-permeable material of the combustion chamber wall, the metallic housing wall forming a reflective side of the microwave channel.
  • a metallic reflective layer can be applied in or onto the microwave-permeable material.
  • at least one such microwave channels can be located one behind the other. Since in such a case the ignition takes place at different times in the individual combustion chambers, the microwaves are then passed through all openings or microwave channels, but only generate ignition in the combustion chamber in which the fuel is in the corresponding ignitable state.
  • the device for coupling in the microwaves is a microwave spark plug according to the patent application EP 15157298.9 on, which is arranged in at least one bore in the combustion chamber wall. The end of this meets the microwave-permeable combustion chamber wall, which forms the microwave window for this microwave spark plug.
  • the rotary piston usually consists of a metallic material, this already forms a reflective layer for the microwaves with its surface.
  • a reflective layer made of a material that is permeable to microwave energy and suitable for the combustion of fuel in the combustion chamber, in particular ceramic or sapphire glass, is at least partially arranged on the rotary piston, in which uneven local geometric metallic structures are arranged Depending on the configuration, microwaves striking the rotary piston are reflected back into the combustion chamber in a concentrated or scattered manner.
  • the geometric metallic structures can be produced without passage points for microwaves.
  • the uneven local geometric structures are therefore expediently designed in the form of particles introduced into the reflective layer or as a metal powder layer. The concentration or scattering of the microwaves in the combustion chamber can thus be controlled in a targeted manner.
  • the combustion chamber wall and / or reflective layer are at least partially designed as a prefabricated sintered insert that can be inserted into the housing wall or the piston wall. This can be done in such a way that either only the combustion chamber wall is introduced into the housing wall or the housing wall is clad with a wall layer enclosing the entire working chamber.
  • the (metallic) rotary piston which can also be completely surrounded by such a wall layer. This simplifies the production of rotary piston internal combustion engines designed in this way.
  • the device for coupling in the microwaves has a microwave generator which generates microwaves with a frequency of 25 GHz to 95 GHz, preferably 30 to 75 GHz, and which controls the time, frequency, amplitude and Has type of coupling of the microwaves.
  • the type of coupling is understood to mean whether the coupling is via individual pulses or as pulse packets or other possible required variants of the control of the microwaves.
  • the device for coupling in the microwaves can preferably have a microwave generator which introduces the microwaves in pulse packets and preferably maintains them even after a fuel has already been ignited. In this way, in addition to ignition, the combustion of the fuel is optimized and the combustion of the fuel is also stimulated after ignition.
  • a particular advantage of the engine is that the microwaves can be introduced in an angle-controlled manner with respect to a crankshaft, so that the ignition can be precisely controlled.
  • the known disadvantages of loss of compression due to the running surface that has no unevenness and the space ignition of the individual fuel particles are avoided. It is possible to provide any required ignition energy at any point and to produce uniform combustion in the entire combustion chamber by selecting the number of microwave windows and the corresponding parameters for the supply of microwaves. Basically, all design options for the tread are possible. A working chamber with a circular cross section is also possible. Furthermore, through the selection of the material and the design of the housing, the motor can be designed depending on the application, in particular if a sintered material such as a ceramic material is used.
  • the engine according to the invention also allows precise control of the start of a space ignition of a fuel in a combustion chamber, so that an optimal low-pollutant combustion of the fuel with an increased efficiency compared to conventional rotary piston internal combustion engines is achieved.
  • the invention enables the reliable ignition of lean fuel-air / gas mixtures, which makes additional enrichment for ignition unnecessary and leads to lower fuel consumption. Pollutants and their formation can be regulated by the combustion temperature and the mixing ratio of air and fuel.
  • the combustion according to the invention takes place faster than with conventional ignitions. This results in a "colder" combustion, so that the efficiency increases.
  • lower pollutant emissions can in principle be achieved with colder combustion processes.
  • the colder combustion reduces the concentration of nitrogen oxides in the fuel exhaust gases. Due to the room ignition, the burning process is significantly less dependent on the burning progress in the form of diffusion flames in contrast to conventional combustion. This avoids further heat losses and increases efficiency.
  • a heating phase of the combustion chamber and the air in the oxidation area is significantly less with this

  • microwaves are reflected by metal, so that the microwaves coupled into the combustion chamber 9 are located in the entire combustion chamber 9 and can energize the fuel located therein in the entire combustion chamber 9 and cause it to ignite. Since both the rotary piston 6 and the housing 2 are usually made of metal, the microwaves coupled into the combustion chamber 9 are reflected back and forth between the rotary piston 6 and the housing 2. If the walls forming the combustion chamber 9 are made of a microwave-permeable material, as in the exemplary embodiment the combustion chamber wall 4 or the reflective layer 8 are formed on the metallic housing 2 or a metallic core 14 of the rotary piston 6, the microwaves are somewhat attenuated, but still held in the combustion chamber 9.
