(FR) PROCÉDÉS ET APPAREILS UTILISANT LES SOUPAPES D'UN MOTEUR À LA FOIS POUR L'ADMISSION ET POUR L'ÉCHAPPEMENT
Abstract
(EN)
Methods and apparatus to selectively use engine valves (24) as both intake and exhaust valves and to selectively operate the engine as a 2 cycle or as a 4 cycle engine. In a disclosed embodiment, the intake valves and the exhaust valves are manifolded together through a small manifold, with the manifold being connectable to the intake manifold or the exhaust manifold through two-way valves (26, 28). In preferably a camless engine, the engine valves may be controlled to operate the intake valves as intake valves only or to operate as both intake valves and exhaust valves, and to operate the exhaust valves as exhaust valves only or to operate the exhaust valves as both intake valves and exhaust valves. Exemplary embodiments are disclosed.

L'invention porte sur des procédés et appareils utilisant les soupapes d'un moteur à la fois pour l'admission et pour l'échappement et permettant de choisir le mode de fonctionnement entre le 2 temps et le quatre temps. Dans une exécution, les soupapes d'admission et d'échappement sont respectivement reliées à de petits collecteurs d'admission et d'échappement et le collecteur central peut communiquer avec l'un ou l'autre des petits collecteurs à l'aide d'une vanne à deux voies. Dans un moteur de préférence sans came, les soupapes d'admission peuvent être commandées pour fonctionner soit uniquement comme soupape d'admission soit comme soupapes d'admission ou d'échappement ou les deux, et les soupapes d'échappement soit uniquement comme soupape d'échappement soit comme soupapes d'admission ou d'échappement. Des exécutions données en exemple sont décrites.
