FUEL SUPPLY DEVICE

To heat a fuel in a fuel chamber quickly in a fuel supply device which heats the fuel to be supplied to an injector.SOLUTION: A fuel supply device includes: an intake pipe member 36 connected to an engine and forming an intake passage therein; an injector 40 connected to the intake pipe member 36 and configured to inject a fuel into the intake passage; a fuel chamber part 50 connected to the upstream side of the injector 40 and configured so that the fuel to be supplied to the injector 40 is accumulated therein; and a heater part 62 which is disposed within the fuel chamber part 50 and heats the fuel accumulated in the fuel chamber part 50. The fuel chamber part 50 includes a partition wall part 71 which partitions an internal space (a chamber room T3) of the fuel chamber part 50 into a first area K1 located close to the heater part 62 in a horizontal direction and a second area K2 located far from the heater part 62.SELECTED DRAWING: Figure 6 【課題】インジェクタに供給する燃料を加熱する燃料供給装置において、燃料チャンバ部内の燃料を素早く加熱する。【解決手段】エンジンに接続され、内部に吸気通路を形成する吸気管部材３６と、前記吸気管部材３６に接続され、前記吸気通路内に燃料を噴射するインジェクタ４０と、前記インジェクタ４０の上流側に接続され、前記インジェクタ４０に供給する燃料を溜める燃料チャンバ部５０と、前記燃料チャンバ部５０内に配置され、前記燃料チャンバ部５０内に溜めた燃料を加熱するヒータ部６２と、を備え、前記燃料チャンバ部５０内には、前記燃料チャンバ部５０の内部空間（チャンバ室Ｔ３）を、水平方向で前記ヒータ部６２に近い第一領域Ｋ１と前記ヒータ部６２から遠い第二領域Ｋ２とに分ける隔壁部７１を備えている。【選択図】図６
