Abstract:
An ECU controls an internal combustion engine which generates a tumble flow inside a cylinder and strengthens the tumble flow by fuel injected near bottom dead center of an intake stroke. The ECU includes an injection timing changing device that changes the injection timing of fuel based on the amount of air drawn into a cylinder of the internal combustion engine.
