Abstract:
A rotation control apparatus for controlling internal combustion engine rotating means for driving an internal combustion engine to control rotation of a rotating shaft of the internal combustion engine, wherein the internal combustion engine rotating means is connected to an auxiliary machine and is selectively connected to and disconnected from the rotating shaft via a clutch, the rotation control apparatus comprising:vibration reducing means, which maintains a rotational speed of the internal combustion engine at a reference rotational speed to reduce an air pressure in a cylinder of the internal combustion engine when an operation of the internal combustion engine is stopped, and subsequently stops rotation of the engine to reduce vibrations of the engine, wherein the vibration reducing means operates the internal combustion engine rotating means to drive the auxiliary machine while the engine is stopped.
