<P>PROBLEM TO BE SOLVED: To prevent large amounts of incombustible HC from being ejected from a catalyst, and to quickly increase a catalyst temperature while suppressing torque fluctuation. <P>SOLUTION: In a hybrid type power generator equipped with an internal combustion engine and an electric motor, the operation of an engine is started under a state that the rate of the load of the engine to the whole load of the engine is higher than a predetermined set value. When the operation of the engine should be started, in-cylinder filling air quantity MCYL as air quantity filled in a cylinder is reduced, and the operation of the engine is started under first operation control to advance an ignition period θ. Then, when an in-cylinder temperature TCYL is made higher than a predetermined set temperature T1, the in-cylinder filling air quantity MCYL is increased, and the first operation control is switched to second operation control to delay the ignition period θ. <P>COPYRIGHT: (C)2008,JPO&INPIT |
