Title (EN) FREE-PISTON INTERNAL COMBUSTION ENGINE
(FR) MOTEUR À COMBUSTION INTERNE À PISTONS LIBRES
Abstract:
(EN) A linear-acting, free-piston internal combustion engine suitable for operation on a four-stroke engine cycle comprises a power piston (11a, 11b) reciprocating in a power chamber (18a, 18b) and a compression piston (23, 23a, 23b) reciprocating in a compression chamber (29a, 29b). The power piston (11a, 11b) and the compression piston (23, 23a, 23b) are rigidly connected by means of a rod (19). The compression piston (23, 23a, 23b) performs alternately an intake stroke and a compression stroke and the power piston (11a, 11b) performs alternately a power stroke and an exhaust stroke.
(FR) L'invention porte sur un moteur à combustion interne à pistons libres, à action linéaire, approprié pour travailler sur un cycle de moteur thermique à quatre temps. Le moteur selon l'invention comprend un piston moteur (11a, 11b) mobile en translation alternative dans une chambre de puissance (18a, 18b) et un piston de compression (23, 23a, 23b) mobile en translation alternative dans une chambre de compression (29a, 29b). Le piston moteur (11a, 11b) et le piston de compression (23, 23a, 23b) sont reliés rigidement au moyen d'une bielle (19). Le piston de compression (23, 23a, 23b) exécute alternativement une course d'admission et une course de compression et le piston moteur (11a, 11b) exécute alternativement une course de combustion et une course d'échappement.
