摘要： A fuel injection control apparatus is provided with a first valve opening timing determination portion that determines a first valve opening timing on the basis of a collision signal that is included in detected signals of an in-cylinder pressure sensor and indicates a collision between a movable core and a valve element and a second valve opening timing determination portion that determines a second valve opening timing on the basis of another collision signal that is included in the detected signals and indicates a collision between the movable core and a stationary core.

摘要： A drive current applied to a coil is reduced from a time at which a first collision signal indicating collision of a movable core with a valve element is input to a time at which a second collision signal indicating collision of the movable core with a stationary core is input.
