  "textContent": "A fuel injection control apparatus of a compression ignition type internal combustion engine includes a controller adapted to control an injector so that pre-stage injection and post-stage injection are performed as fuel injection during one cycle. The controller controls an interval between the timing of the pre-stage injection and the timing of the post-stage injection so that an interval ”t1 between the timing of the pre-stage peak and the timing of the post-stage peak approximately satisfies a condition. The condition is that the interval ”t1 is 0.5 times an inverse number of the frequency f0 at which a combustion noise level becomes the maximum.",
