Title (EN) NON-CIRCULAR DISTRIBUTION VALVE, VALVE ARRANGEMENT ON THE HEAD OF THE CYLINDER OF AN INTERNAL COMBUSTION ENGINE
(FR) SOUPAPE DE DISTRIBUTION NON CIRCULAIRE, AGENCEMENT DE SOUPAPE SUR LA TÊTE DU CYLINDRE D'UN MOTEUR À COMBUSTION INTERNE
Abstract:
(EN) Distribution valves and cylinder heads for endothermic engines having non-conventional geometric shapes can be obtained by means of application of additive manufacturing techniques. The use of a non-conventional geometry, in specific terms different from the conventional cylindrical geometry, allows the production of filling coefficients of the combustion chamber which are substantially greater and which become evident in terms of improvements in power which can be developed for the same cylinder capacity with respect to an endothermic engine with conventional valves.
(FR) Des soupapes de distribution et des culasses pour moteurs endothermiques ayant des formes géométriques non conventionnelles peuvent être obtenues au moyen de techniques de fabrication additive. L'utilisation d'une géométrie non conventionnelle, dans des termes spécifiques différents de la géométrie cylindrique classique, permet la production de coefficients de remplissage de la chambre de combustion qui sont sensiblement supérieurs et qui deviennent évidents en termes d'amélioration de la puissance qui peut être développée pour la même capacité de cylindre par rapport à un moteur endothermique avec des soupapes classiques.
