Abstract
A direct injection spark ignition internal combustion engine includes a fuel injector for directly injecting fuel into a cylinder and intensifies a tumble flow using the fuel injected into the cylinder bore at a time near an intake stroke bottom dead center during homogenous combustion. The thrust force of the fuel injected from the fuel injector is set to intensify the tumble flow based on at least one of the state of the combustion chamber, the temperature of the injected fuel, and the orientation of the injection hole.
