Abstract

"MOTOR DE COMBUSTãO INTERNA COM IGNIçãO CONTROLADA E COM INJEçãO DIRETA" A invenção refere-se a um motor de combustão interna com ignição controlada e com injeção direta, caracterizado em que pelo menos um dos condutos de admissão (24) comporta meios para criar, no cilindro (10), pelo menos em algumas fases de funcionamento do motor, um fluxo conhecido como "tombamento", e em que um injetor de combustível (42) é implantado de modo a desembocar no cilindro, de tal modo que o jato de combustível tende a ser interceptado pela parte do fluxo que circula no sentido oposto ao do jato e que se dirige à vela de ignição.
