Abstract
L'INVENTION SE RAPPORTE A UN MOTEUR A COMPRESSION D'AIR ET A INJECTION DANS UNE CHAMBRE DE COMBUSTION CREUSEE DANS LA TETE DU PISTON, PAR L'INTERMEDIAIRE D'UN CANAL DE JONCTION DANS LEQUEL SE TROUVE L'ORIFICE D'INJECTION DE L'INJECTEUR. SELON L'INVENTION, LA PROJECTION DU POINT 7 D'INJECTION SUR LA SURFACE 8 DE LA CULASSE SE SITUE DANS UN CERCLE AYANT AU PLUS 1,1 FOIS LE DIAMETRE D DE LA CHAMBRE DE COMBUSTION 2 ET LA DISTANCE A ENTRE LE POINT D'INJECTION 7 ET LA PAROI 9 DE LA CHAMBRE 2 EST INFERIEURE OU EGALE A 30 DU DIAMETRE D. L'INVENTION AMELIORE LE FONCTIONNEMENT DU MOTEUR AU RALENTI ET DANS LA PLAGE INFERIEURE DE MARCHE.
