摘要：
A spark-ignition type internal combustion engine has a fuel injection valve for supplying fuel directly to a cylinder and a spark plug arranged near the fuel injection valve for igniting fuel in the cylinder. Auxiliary fuel injection is performed in the vicinity of the top dead center of the compression stroke, the subsequent main fuel injection is performed after the auxiliary fuel injection is terminated, and concurrently, the spray produced by auxiliary fuel injection is ignited by the spark plug.
