In a hybrid power output apparatus including an engine and a motor generator apparatus, a fuel supply stop process of stopping the supply of fuel is performed after performing a fuel increase process of increasing the amount of the fuel in a combustion chamber from that at a present state, as a control for preventing the deterioration of a catalyst upon stopping the engine. This makes it possible to prevent the catalyst from being exposed to a lean atmosphere.
