Title (EN) TWO-STROKE ENGINE AND RELATED METHODS
(FR) MOTEUR À DEUX TEMPS ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) A two-stroke engine (10) includes a crankshaft (12) that is rotatable about an axis (14), and an engine block (20) that includes a combustion cylinder (28) and a compression cylinder (26). A first piston (38) is slidably disposed within the combustion cylinder (28) and is operatively coupled to the crankshaft (12) for reciprocating movement within the combustion cylinder (28) through a power stroke during each rotation of the crankshaft (12) about the axis (14). A second piston (36) is slidably disposed within the compression cylinder (26) and is operatively coupled to the crankshaft (12) for reciprocating movement within the compression cylinder (26) such that fresh air is received and compressed in the compression cylinder (26) during each rotation of the crankshaft (12) about the axis (14).
(FR) La présente invention concerne un moteur à deux temps (10) comprenant un vilebrequin (12) qui peut se mettre en rotation autour d'un axe (14) et un bloc-moteur (20) qui comprend un cylindre de combustion (28) et un cylindre de compression (26). Un premier piston (38) est disposé de manière coulissante à l'intérieur du cylindre de combustion (28) et est couplé en fonctionnement au vilebrequin (12) en vue d'un mouvement en va-et-vient à l'intérieur du cylindre de combustion (28) à travers une course de combustion lors de chaque rotation du vilebrequin (12) autour de l'axe (14). Un second piston (36) est disposé de manière coulissante à l'intérieur du cylindre de compression (26) et est couplé en fonctionnement au vilebrequin (12) en vue d'un mouvement en va-et-vient à l'intérieur du cylindre de compression (26) de sorte que de l'air frais est reçu et comprimé dans le cylindre de compression (26) lors de chaque rotation du vilebrequin (12) autour de l'axe (14).
