<p>When an internal combustion engine (10) is started and the rotor of a valve-timing changing mechanism (30) is rotated toward the advanced side to a locked phase, an electronic control device (100), which controls the engine, reduces the amount of operation of a high-pressure fuel pump (80) and a vacuum pump (90), which are auxiliary devices driven by the driving force of an intake camshaft (32). Therefore, the rotor is quickly rotated to the locked phase and is fixed in the locked position.</p> |
