Abstract
An injection control apparatus includes an injector for injecting fuel which is accumulated under pressure toward a combustion chamber, an injector driver for supplying a current to an electromagnetic actuator used for a solenoid valve, and a state detection unit for detecting a state of an engine or an ambient environment. A valve opening control unit supplies a first current to the electromagnetic actuator for opening the solenoid valve. An opened-state maintaining control unit supplies a second current to the electromagnetic actuator for maintaining the solenoid valve continuously in an opened position. A timing control unit variably adjusts a period of time from a starting time of the valve opening control unit to a time when the opened-state maintaining control unit becomes active in place of the valve opening control unit, in accordance with a result of detection provided by the state detection unit.
