Abstract:
1. A power output apparatus comprising: an engine that outputs power to a drive shaft; an air flow rate adjustment mechanism that adjusts an air flow rate supplied to the engine; an exhaust system having a catalyst, for discharging exhaust gas from the engine; a first suppression controller that, after startup of the engine, controls the air flow rate adjustment mechanism so as to limit the air flow rate to a level equal to or less than a predetermined flow rate; and a second suppression controller that, at a predetermined timing, transitions an operation of the engine to a reduced hydrocarbon operation state established so as to reduce a quantity of hydrocarbons within the exhaust gas, and cancels the limit on the air flow rate, wherein the air flow rate during a control of the first suppression controller is less than the air flow rate during a control of the second compression controller.
