PURPOSE:To improve response quality at the time of coupling a power source to an output shaft through the method of a clutch, by such means that at least one of the power sources is connected to the output shaft through a transmission device while a standby power source is operated always in an idling condition. CONSTITUTION:An internal combustion engine having plural power sources is constituted by the first engine 1, the second engine 2, clutch 3, output shaft 4 and flywheel 5. The engine 2, not coupled to always the output shaft 4, is operated in an idle state. In this way, response quality at the time of coupling the engine 2 to the output shaft 4 with the clutch 3 can be improved, then power in an optimum condition can be output in accordance with a condition in use. |
