Abstract

"MOTOR DE COMBUSTãO INTERNA COM INJEçãO DIRETA". A presente invenção refere-se a um Motor de combustão interna, especialmente motor Otto, com válvulas de admissão (20) e com um dispositivo de injeção (40) para combustível (42) que é de tal modo disposto e executado que injeta o combustível (42) diretamente para dentro de uma câmara de combustão (16) de cilindros de trabalho (14) do motor de combustão interna. No caso, as válvulas de admissão (20) possuem pelo menos na área de uma canelura (68) das mesmas uma superfície que é realizada de tal modo que age contra uma coqueificação.
