Abstract:
1. An engine starting control apparatus comprising: a motor control section configured to operate an electric motor to crank an engine with an output of the electric motor being adjustable; a valve timing control section configured to operate a variable valve operating mechanism when the engine is started to change at least a close timing of an intake valve of the engine from an initial timing corresponding to a state in which the engine is stopped to a start timing for starting the engine, the valve timing control section operating the variable valve operating mechanism to set the close timing of the intake valve such that the start timing is set to be closer to an intake bottom dead center during a single engine start as compared to the initial timing; and a start control section configured to continuously decrease the output of the electric motor as the close timing of the intake valve draws closer to the start timing from the initial timing during the single engine start.
