Definitions

  • piston can be only one organ in order to lighten the system (this is possible only when the symmetry regarding the cylin der axis is guaranteed by means of wheel works).
  • thermodinamic efficiency In order to improve the thermodinamic efficiency this new crank mechanism must possess some characteristics that can carry out a thermodinamic cycle that gets nearer the limit- cycle. It is well known that in the limit-cycle combustion takes place at constant volume and subtend isentropic trans ⁇ ormations.
  • thermodinamic cycle
  • crank mechanism is more durable than the traditional one because it saves organs that are less protected from the wear.
  • this new type of crank mechanism permits very high turn velocities both because the crankshafts, turning in opposite each other way, allow a better balancing, and because the forces of inertia, that are due to the masses ha ving shuttle, are unloaded on the two crank mechanisms.

Abstract

Dans le but d'améliorer le rendement thermodynamique et organique du moteur par rapport aux moteurs actuels, l'invention propose un nouveau type de transmission à bielle et manivelle, double et inversée, ayant les caractéristiques suivantes: le mouvement du piston au voisinage du point mort haut est bien plus faible qu'au point mort bas; les courses de coulisseau extérieur (course de détente et d'admission) à la même vitesse de rotation se déroulent en un temps plus long que les courses de coulisseau intérieur (courses de compression et d'échappement); pendant le fonctionnement, il n'y a pas de forces de fermeture qui risqueraient de pousser le piston contre la paroi du cylindre. Ces caractéristiques permettent d'améliorer la combustion, de réduire l'échange de chaleur et de limiter l'usure due au frottement entre le piston et la paroi du cylindre, ce qui évite le risque de grippage.
