Title (EN) INTERNAL COMBUSTION ENGINE WITH TURBULENCE CHAMBER
(FR) MOTEUR A COMBUSTION INTERNE AVEC CHAMBRE DE TURBULENCE
Abstract: front page image
(EN)Internal combustion engine comprising at least a combustion chamber, a piston (12), a turbulence chamber (17) provided inside the overhead cylinder (13) above the piston (12), and an ignition device (19) leading to the turbulence chamber (17). The invention is characterized in that at least one channel (20) provided at the base of the overhead cylinder (13), opens tangentially along the walls of the turbulence chamber (17). The channel (20) has, at its origine, a width substantially equal to the diameter of the seat of the intake valve (14) and narrows as it goes deeper in the direction of the turbulence chamber (17). This engine embodies an improvement of the Otto type engines.
(FR)Moteur a combustion interne comportant au moins une chambre de combustion, un piston (12), une chambre de turbulence (17) menagee a l"interieur de la culasse (13) au-dessus du piston (12), et un dispositif d"allumage (19) debouchant dans la chambre de turbulence (17). Selon la caracteristique principale de l"invention, au moins un canal (20), menage a la base de la culasse (13), debouche tangentiellement le long des parois de la chambre de turbulence (17). Le canal (20) a, a son origine, une largeur sensiblement egale au diametre du siege de la soupape d"admission (14) et se retrecit en s"approfondissant en direction de la chambre de turbulence (17). Ce moteur constitue un perfectionnement des moteurs du type Otto.
