Abstract

Moteur à combustion interne pouvant comprendre un piston se déplaçant dans un cylindre et une culasse de cylindre disposée en face de la tête de piston dans le cylindre. La culasse de cylindre peut facultativement être mobile entre une position de taux de compression plus élevé, plus proche du point mort haut du piston, et une position de taux de compression plus faible, plus éloignée du point mort haut du piston. Au moins un orifice d'admission peut fournir un fluide comprenant de l'air d'admission à une chambre de combustion à l'intérieur du cylindre. Les gaz de combustion peuvent être dirigés hors de la chambre de combustion par au moins un orifice d'échappement. L'orifice d'admission et/ou l'orifice d'échappement peuvent être ouverts ou fermés par le fonctionnement d'une soupape manchon qui entoure au moins partiellement le piston. L'invention décrit les articles, systèmes et procédés qui s'y rapportent.
