<p>A rotational speed control apparatus for an engine (10) is provided. The engine (10) is configured to drive a compressor (24) and includes an ignition plug (18). The rotational speed control apparatus includes an electronic control unit (25). The electronic control unit (25) is configured to: (a) correct a torque of the engine (10) through feedback such that a rotational speed of the engine (10) during idle operation becomes close to a target rotational speed; and (b) adjust the ignition timing such that a reserve torque that is ensured is larger when a first changeover is started than when a second changeover is started, the first changeover being a changeover from a stopped state of the compressor (24) to a driven state of the compressor (24), the second changeover being a changeover from the driven state of the compressor (24) to the stopped state of the compressor (24).</p> |
