1. A power output apparatus that outputs power to a driveshaft, said power output apparatus comprising:

  • an internal combustion engine that is operable independently of a rotating state of the driveshaft;

    a motoring structure that is capable of motoring the internal combustion engine;

    an oxygen concentration measurement unit that is located in an exhaust system of the internal combustion engine to measure an oxygen concentration in exhaust emission from the internal combustion engine;

    a status detection module that detects a current status of the oxygen concentration measurement unit based on a measurement result of the oxygen concentration measurement unit, when a predetermined execution condition is satisfied in a fuel injection-stop engine rotation state where the internal combustion engine is rotated with stop of fuel injection; and

    a status detection-time control module that controls the internal combustion engine and the motoring structure to maintain the fuel injection-stop engine rotation state upon satisfaction of a predetermined cancellation condition for canceling the fuel injection-stop engine rotation state during detection of the current status of the oxygen concentration measurement unit by said status detection module, said status detection-time control module controlling the internal combustion engine and the motoring structure to cancel the fuel injection-stop engine rotation state on completion of the detection of the current status.
