Title (EN) BARRIER RING AND ASSEMBLY FOR A CYLINDER OF AN OPPOSED-PISTON ENGINE
(FR) ANNEAU D’ARRÊT ET ENSEMBLE POUR UN CYLINDRE D'UN MOTEUR À PISTONS OPPOSÉS
Abstract:
(EN) A barrier ring for a cylinder assembly for an opposed-piston engine fits into a groove fashioned into a portion of the cylinder liner that is adjacent to the top dead center location of the end surfaces of the pistons, in a volume of the cylinder liner that defines the combustion chamber. The barrier ring and groove are part of a barrier assembly that prevents heat generated during combustion from reaching the outer wall of the cylinder assembly, reducing the need for conventional cooling systems and increasing the amount of heat retained in the combustion chamber. The barrier assembly allows for increased engine efficiency because of the combustion heat retained in the combustion chamber, as well as a reduction in the overall size of the engine because of the reduction in engine cooling needed.
(FR) La présente invention concerne un anneau d’arrêt pour un ensemble de cylindre pour un moteur à pistons opposés qui s'ajuste dans une rainure usinée dans une partie de la chemise de cylindre qui est adjacente à la position de point mort haut des surfaces d'extrémité des pistons, dans un volume de la chemise de cylindre qui définit la chambre de combustion. L'anneau d'arrêt et la rainure font partie d'un ensemble d’arrêt qui empêche la chaleur générée pendant la combustion d'atteindre la paroi externe de l'ensemble de cylindre, de manière à réduire le besoin de systèmes de refroidissement conventionnels et d'augmenter la quantité de chaleur retenue dans la chambre de combustion. L'ensemble d’arrêt permet une augmentation du rendement du moteur en raison de la chaleur de combustion retenue dans la chambre de combustion, ainsi qu'une réduction de la taille totale du moteur en raison de la réduction du besoin de refroidissement de moteur.
