A fuel injection control apparatus of an internal combustion engine of the present invention performs control for a common rail diesel engine so that at a timing when a piston reaches compression top dead center, the rate of heat production due to the combustion of fuel injected in pre-injection is substantially maximal, and furthermore so that the combustion of fuel injected in main injection is started in the vicinity of this timing. As a result, the combustion of fuel injected in main injection is started by fully utilizing the heat production amount due to the pre-injection. Also, this avoids the production of reverse torque, as well as ensures maximizing the amount of torque produced by the combustion of fuel injected in main injection.
