A post injection is utilized in a more effective manner. In an internal combustion engine which is provided with a fuel injection valve for injecting fuel into a cylinder of the internal combustion engine, in cases where a post injection is carried out after a main injection of fuel from the fuel injection valve, when a rotation speed of the internal combustion engine is equal to or more than a first predetermined speed, a penetration force of fuel in the post injection is made larger than a penetration force of fuel in the main injection, whereas when the rotation speed of the internal combustion engine is less than a second predetermined speed which is equal to or less than the first predetermined speed, the penetration force of fuel in the post injection is made smaller than the penetration force of fuel in the main injection.
