Abstract
(EN)
This invention relates to engine-building and more particularly to a method of piston internal combustion engine working and may be used in stationary power-generating plants and in transport. A method of piston internal combustion engine working comprising the suction valve (1) opening into the cylinder (8) over-piston cavity, feeding the working medium into it before the suction valve (1) shutting off; further compressing and burning of the working medium with its further expansion and discharge of the worked-out gases. A detonating additive is added into the working medium, but the working medium expansion is preferably affected at its constant pressure and the over-piston cavity variable volume. The piston internal combustion engine comprises a rocker (5) of variable length which is provided by telescopic spring (24) of variable rigidity and hydrocylinder (13) and compensator (4) which is provided by a telescopic spring (28) of variable rigidity and hydrocylinder (31). A rocker (5) of variable length provides fuel burning at the constant pressure of the working medium and variable volume of the over-piston cavity. Compensator (4) provides automatical adjusting of the given compression pressure rate.

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.
