Definitions

  • the invention relates to a rotary internal combustion engine, wherein compression is provided separately by means of an external compressor.
  • the technical problem solved by the invention is that of designing an engine which will provide higher energy efficiency as compared to prior art internal combustion engines .
  • the said technical problem is overcome by separating the intake and compression strokes from the combustion chamber through the use of a separate compressor and of a specially shaped piston inside the cylinder, wherein the combustion chamber is shut by a movable shutter, the movement thereof being made possible by the shape of the piston as such.
  • the air entering the cylinder is compressed beforehand.
  • Figure 2 the engine Functional description of the compressor ( Figure 1) :
  • the piston takes in a large quantity of air and pushes almost all thereof out of the cylinder. Due to the shape of the piston (4), toward the end the pressures are generated slowly and not abruptly; also the exhaustion of air allows extraordinary compression characteristics to be attained due to the shape of the piston. The volume is not diminished linearly, but more slowly toward the end, and such great force acting on a small volume allows high pressures to be obtained.
  • the pressure of the movable shutter (3) onto the piston (4) walls is provided by a spring (2 ) .
  • a larger amount of air is stored in the pressurized container (1), filled by a compressor or by a plurality of compressors, the function thereof being besides filling the pressurized container also to utilize the braking energy of the vehicle.
  • This is obtained by disposing three compressors having different capacities on the drive shaft or shafts.
  • the compressors have different capacities in regard to the pressure to be obtained, the quantity of air required to do so, and of the required braking forces.
  • several stages of compression/resistance are obtained.
  • the release of the gas pedal occurs in several stages, resulting in a controlled braking. That way, employing three compressors, 7 braking stages would be installed on the pedal: 1 st stage - 1 st compressor, 2 nd stage - 2 nd compressor, ...
  • the driver can therefore control the braking power, provided by the compression braking of the compressor, the required air being stored in the pressurized container (1) .
  • energy is stored with minimal losses, being that the pressure in the container does not diminish with time.
  • the said air is subsequently utilized in the engine in the compression stroke.
  • the coupling of the compressors with the drive shaft or shafts is carried out as required, namely when the pressure drops inside the pressurized container (1), and during braking. That way the braking energy which heretofore was lost is utilized.
  • the compressors are also engaged when the pressure in the pressurized container drops, namely:
  • the air flows via a reducing valve (8) to the chamber (7) adjacent the engine cylinder, thereby allowing a constant working pressure. From the said chamber the desired quantity of air is released into the engine cylinder via a computer-controlled valve (6).
  • the fuel is added according to the widely known principles of fuel injection, and the expansion makes the piston (4) rotate.
  • a spark plug is required in a gasoline engine to provide the necessary spark. The moment of ignition must not take place before the movable shutter (3) reaches its lowest point, because an elevated pressure on the wall of the movable shutter would prevent the movable shutter from sliding downwards, thereby creating a "hole" or loss of compression.
  • the ignition may be delayed at will, thereby increasing the working volume (computer- controlled) and consequently the flexibility of the engine according to particular requirements. Given that the volume of the cylinder is relatively very large, the compression may be entirely utilized across the entire cylinder.
  • the pressure of the movable shutter (3) on the walls of the piston (4) is provided by a spring (2) or otherwise.

Abstract

L'invention concerne un moteur à combustion interne rotatif, la compression étant effectuée séparément au moyen d'un compresseur externe, c'est-à-dire par séparation des courses d'admission et de compression de la chambre de combustion au moyen d'un compresseur séparé et d'un piston de forme particulière (4) à l'intérieur du cylindre, la chambre de combustion étant fermée par un volet mobile, dont le mouvement est rendu possible par la forme du piston en tant que tel. L'air préalablement comprimé pénétrant dans le cylindre provient d'une chambre à pression de travail constante.
