Abstract
A direct injection spark ignition internal combustion engine includes a fuel injection valve and fuel injection control device that controls fuel injection such that a fuel is injected from an upper area of an engine cylinder toward a top face of a piston through the fuel injection valve. The fuel injection control device switches a thrust force of the fuel injected from the fuel injection valve between at least two levels such that the thrust force of the injected fuel becomes weaker when the position of the piston is high than when the position of the piston is low.
