Abstract
A direct-injection spark-ignition engine includes a spark plug provided approximately at the center of the ceiling of a combustion chamber, and an injector having at its downstream end a nozzle which is located in an upper peripheral area of the combustion chamber, in which multiple openings are formed in the nozzle of the injector. Fuel is injected from the nozzle of the injector directly toward the proximity of an electrode of the spark plug. The directions of axis lines of the individual openings are set such that central points of fuel jets spewed out of the individual openings do not lie on the spark plug but are distributed around the electrode, slightly separated therefrom.
