Definitions

  • the invention relates to a process and a combustion chamber with variable turbulence used in high speed engines.
  • the method and the unitary combustion chamber are also known, in which the absence of throttles in the path of the working fluid ensures a relatively reduced consumption of fuel, but has the disadvantage that they cannot operate at high speeds, following d '' a reduced level of organization of turbulence.
  • the method and the synthetic combustion chamber, in accordance with the present invention overcome the disadvantages presented above, in that, in order to achieve reduced fuel consumption and increased flexibility of compression-ignition engines both as regards the range of turns and / or load, as regards the dimensional range, ensures the integral organization by volume of the circulation of fluid in the combustion chamber by the only temporary separation of the space from the tower room.
  • the chamber forming a unitary whole, the combustion process as a whole constituting a synthesis between the chamber process unitary and the divided chamber method, the reinforcement of the turbulence being obtained as a result of the vectorial sum of at least three vortices, vortices with three-dimensional circulation and also by the enhancement of the threshold effect (squish) created by the piston, which accentuates the effect of transfer of the fluid between the one two enclosures which are separated by spatial profile which penetrates into the separation channel, profile defined by at least three steering surfaces, which produce vortices with three-dimensional circulation and constitute as a mobile braking threshold of the vortex enclosure, by concentrating the rich mixture which burns in the zone d u transfer channel, the circulation of the fluid in the swirling enclosure being thus determined, in order to meet the jet of fuel by equi-current and to move part of the fuel over the incandescent head of a candle.
  • FIGS. 1 ... 7 Three examples of embodiments of the combustion chambers which apply the method according to the present invention are given, in relation to FIGS. 1 ... 7, which represent:
  • injectors with several orifices allows the application of the method and of constructive solutions, in accordance with the present invention also for engines of large dimensions.
  • the air circulation in the final compression faze first encounters an ignition rod and then enters the injection zone, entraining the jet of fuel by equicurrent.
