Abstract
A fuel injection control device includes a valve closing detection unit to detect a valve closing timing by using either of an electromotive force quantity detection mode and an timing detection mode and a selection unit to select either of the electromotive force quantity detection mode and the timing detection mode for detecting the valve closing timing, and the selection unit: selects the timing detection mode when a requested injection quantity is larger than a prescribed reference injection quantity in partial lift injection; and selects the electromotive force quantity detection mode when the requested injection quantity is smaller than the reference injection quantity.
