Abstract

Dans ce moteur comportant une chambre de combustion (3) formée dans un cylindre (2) et délimité par un piston alternatif (5) relié par une bielle à un vilebrequin d'un carter, et comportant un canal de transfert réunissant le carter (4) à une fenêtre d'entrée (12) de la chambre de combustion et relié par une soupape anti-retour (21) à un canal (21) de circulation de gaz, et un dispositif de préparation du mélange, un élément de guidage d'écoulement (23, 33, 95) qui étale le courant de gaz (40) est disposé dans le trajet d'écoulement de ce courant de gaz passant du canal (22) au canal de transfert (14).Application notamment aux moteurs deux temps de scies à chaîne.
