Zusammenfassung:To create a novel method for starting preparation of an internal combustion engine configured as a gas engine or a dual-fuel engine.SOLUTION: In a step a), at first, when a cylinder-group-specific fuel supply valve (16) is closed, cylinder-individual fuel supply valves (17) are closed and a vent valve (18) is closed, a cleaning medium is filled in a predetermined manner in a fuel supply system (13) from which a gaseous fuel is discharged beforehand, and a pressure prevailing in the fuel supply system (13) is monitored whether the pressure is in a predetermined pressure range for a predetermined period. Then, when it is confirmed in the step a) that the pressure prevailing in the fuel supply system (13) is in the predetermined pressure range for the predetermined period, in a subsequent step b), the gaseous fuel is filled in the fuel supply system (13).SELECTED DRAWING: Figure 1 【課題】ガスエンジン又は二元燃料エンジンとして構成された内燃機関の新しい始動準備方法を創出すること。【解決手段】ステップa)では、まず、シリンダ群固有の燃料供給弁(16)が閉じられ、シリンダ固有の燃料供給弁(17)が閉じられ、通気弁(18)が閉じられた場合に、前もってガス燃料が放出されていた燃料供給システム(13)に、浄化媒体が所定の方法で充填され、燃料供給システム(13)内に広まっている圧力が、所定の期間にわたって、所定の圧力範囲内にあるかが監視される。次に、ステップa)において燃料供給システム(13)内に広まっている圧力が所定の期間にわたって所定の圧力範囲内にあることが確認される場合、後続のステップb)において、燃料供給システム(13)にガス燃料が充填される。【選択図】図1
