To suppress generation of a fuel wall flow in a combustion chamber, by providing an induction port jetting an air flow toward a side of the other intake valve in the vicinity of one intake valve, in a direct injection spark ignition internal combustion engine provided with a fuel injection valve having a pair of the intake valves and a spark plug.

At partial load time, during a suction stroke, when it leads to the prescribed fuel injection timing, a rotary valve 14 is opened, so that intake air is partly jetted into a combustion chamber 4 from an induction port 13 via an intake port 5. Almost simultaneously with this jetting, fuel in an amount in accordance with an operating condition of an engine is injected toward inside the combustion chamber 4 from a fuel injection valve 11. Here, since an air flow jetted from the induction port 13 collides against the sideward of injection fuel B, its atomization direction is displaced to a side of an intake valve 7B, and the injection fuel B collides against a valve stem and an umbrella part of the intake valve 7B. In this way, atomization is promoted, in this combustion atomization C, a mixture is formed in the combustion chamber 4, to be ignited by a spark plug 12.
