Abstract

Procédé d'exploitation d'un moteur à explosion à pistons trouvant application dans le domaine de la construction de moteurs et notamment dans les groupes d'alimentation fixes et les véhicules. Selon ce procédé d'exploitation d'un moteur à explosion à pistons, la soupape d'aspiration (1) débouche dans la cavité située au-dessus du piston dans le cylindre (8) et y introduit le milieu de travail avant de se refermer, et le milieu de travail subit une compression et une combustion puis une dilatation et les gaz brûlés sont évacués. Un additif détonant est ajouté au milieu de travail, mais la dilatation de ce dernier se faisant de préférence sous une pression constante du milieu de travail et avec un volume variable de la cavité située au-dessus du piston. Ce moteur à explosion à pistons comporte un culbuteur (5) de longueur variable réalisé à l'aide d'un ressort télescopant (24) de rigidité variable, ainsi qu'un cylindre hydraulique (13) et un orifice de compensation (4) réalisé à l'aide d'un ressort télescopique (28) de rigidité variable et d'un cylindre hydraulique (31). Le culbuteur (5) de longueur variable permet d'assurer la combustion du carburant à la pression constante du milieu de travail et avec un volume variable de la cavité située au-dessus du piston. L'orifice de compensation (4) assure le réglage automatique du taux de pression de compression prédéterminé.
