FUEL SUPPLY DEVICE OF INTERNAL COMBUSTION ENGINE

To provide a fuel supply device of an internal combustion engine suppressing knocking of the internal combustion engine, preventing the damage of an exhaust system component, suppressing enlargement/an increase in weight of the internal combustion engine or the whole of the fuel supply device, and capable of reducing costs.SOLUTION: A fuel supply device of an internal combustion engine includes a fuel tank 21 that collects fuel including at least a part of fuel having water absorption, a fuel injection device 22, a fuel supply pipe 23 that communicates with the fuel tank 21 to lead out the fuel to the fuel injection device 22, and an absorbing material 24 that is arranged in the fuel supply tube 23 and can absorb water. Moisture absorbed to the absorbing material 24 is discharged to the fuel supply pipe 23 according to a request of an internal combustion engine 1.SELECTED DRAWING: Figure 4 【課題】内燃機関のノッキングを抑制するとともに排気系部品の損傷を防止し、内燃機関や燃料供給装置全体の肥大化・重量化を抑制し、コスト低減可能な内燃機関の燃料供給装置を提供する。【解決手段】内燃機関の燃料供給装置において、吸水性を有する燃料を少なくとも一部含む燃料を貯留する燃料タンク21と、燃料噴射装置22と、燃料タンク21に連通し燃料噴射装置22へ燃料を導出するための燃料供給管23と、燃料供給管23内に配設され少なくとも水を吸着できる吸着材24とを有し、内燃機関1の要求に応じて吸着材24に吸着された水分を燃料供給管23に排出する。【選択図】図４
