A direct injection internal combustion engine in which current velocity of gas in the vicinity of firing part of an ignition plug is controlled, and mixture gas suitable for ignition can stay for a long time. In the direct injection internal combustion engine, a portion (28) for reflecting a part of fuel injected from an injecting portion (11) having a passage (25) for directing fuel injected from the injecting portion (11) directly toward the vicinity of firing part, and directing the fuel indirectly toward the vicinity of the firing part is provided on the wall face between the injecting portion (11) of a combustion chamber (6) and the firing part (17). With such an arrangement, difference in arriving time of mixture gas suitable for ignition and passing through two sorts of passages, namely, direct and indirect passages, and current velocity of gas reaching the firing part by reflection can be controlled and the mixture gas stays in the vicinity of firing part for a long time. |
