(EN) INTERNAL COMBUSTION ENGINE
(FR) MOTEUR A COMBUSTION INTERNE
Abstract
(EN)
Internal combustion engine having a main combustion chamber (26) and a subsidiary combustion chamber (30) interconnected by a passageway (32) having a flow control element (34) arranged therein to cyclically vary the extent of communication provided between the main and subsidiary combustion chambers. In use, a subsidiary air fuel charge is first ignited in the subsidiary combustion chamber (30) with the control element (34) substantially blocking communication between the two combustion chambers (30, 26). Then the control element (34) is moved to permit the igniting air fuel charge in the subsidiary combustion chamber (30) to move through the passageway (32) to ignite a main air fuel charge in the main combustion chamber (26). The control element (34) is reciprocable having a head portion (82) which is moved from within the passageway (32), into the subsidiary combustion chamber (30) to effect opening of communication between the combustion chambers (26, 30).
(FR)
Un moteur à combustion interne possède une chambre de combustion principale (26) et une chambre de combustion secondaire (30) reliées entre elles par un passage (32) ayant un élément de commande d'écoulement (34) disposé à l'intérieur du passage pour faire varier de manière cyclique le degré de communication entre les chambres de combustion principale et secondaire. En utilisation, une charge secondaire d'air-carburant est d'abord allumée dans la chambre de combustion secondaire (30), l'élément de commande (34) bloquant sensiblement toute communication entre les deux chambres de combustion (30, 26). Ensuite, l'élément de commande (34) est déplacé pour permettre à la charge d'air-carburant d'allumage dans la chambre de combustion secondaire (30) de se déplacer au travers du passage (32) pour allumer une charge principale d'air-carburant dans la chambre de combustion principale (26). L'élément de commande (34) est mû d'un mouvement alternatif et possède une partie de tête (82) qui est déplacée depuis l'intérieur du passage (32), dans la chambre de combustion secondaire (30) pour effectuer l'ouverture de commnunication entre les deux chambres de combustion (26, 30).
