To provide a propulsion mechanism which is a simpler structure than before and capable of stably operating in a propulsion mechanism of a DF engine driven by selecting a diffusing combustion and a premixed combustion, and of an electric propulsion ship powered by battery.SOLUTION: A propulsion mechanism 3 of an electric propulsion ship 1 comprises a generator 15 to generate electricity with a DF engine 23 driven by selecting diffusion combustion of liquid fuel or by premixed combustion of gas fuel, a battery 13, an electric motor 11 to drive a propeller 17 when power is supplied to the electric motor from the generator 15 or the battery 13, and a switching controller 9 to control the connecting selection of the generator 15, the battery 13, and the electric motor 11, and to control the distribution of power. The electric motor 11 is a DC motor. The switching controller 9 connects the electric motor 11 and the battery 13 when a load change of the electric motor 11 is beyond the predetermined threshold in the case that the motor 11 with the connected state to the generator 15 is in a power running by receiving power supply from the generator 15 while the DF engine 23 is driven by the premixed combustion.SELECTED DRAWING: Figure 1

    【課題】拡散燃焼と予混合燃焼を選択して駆動するDFエンジンと、蓄電池を電源とする電気推進船の推進機構において、従来よりも構造が単純で安定した動作が可能な推進機構の提供。【解決手段】液体燃料の拡散燃焼又はガス燃料の予混合燃焼を選択して駆動するDFエンジン23で発電する発電機15と、蓄電池13と、発電機15又は蓄電池13から電力が供給されるとプロペラ17を駆動する電動モータ11と、発電機15、蓄電池13、及び電動モータ11の接続の選択及び電力の分配を制御する切替制御部9を備える、電気推進船1の推進機構3であって、電動モータ11は直流モータであり、切替制御部9は、DFエンジン23が予混合燃焼で駆動中に、電動モータ11が発電機15と接続された状態で発電機15から電力の供給を受けて力行している場合、電動モータ11の負荷変動が予め定められた閾値を超えると電動モータ11と蓄電池13を接続する。【選択図】図1
