According to the present invention, a fuel supply preventing system during engine ignition comprises: a negative pressure chamber formed in a fuel injection port of a filler pipe into which a fuel refueling gun is inserted; a negative pressure hose connecting the negative pressure chamber and an intake system of an engine, and generating intake negative pressure by sealing the negative pressure chamber in case of engine ignition; and a fuel cap inserted into the fuel injection port, operated by the intake negative pressure generated in the negative pressure hose to fixate a sealing state of the negative pressure chamber, and formed to be separated from the fuel injection port when the engine ignition is finished for the fuel cap not to be operated.

    본 발명은 연료 주유건이 삽입되는 필러파이프의 연료 주입구에 형성되는 부압 챔버와 상기 부압 챔버와 엔진의 흡기계를 연결하고, 엔진의 시동 시 상기 부압 챔버가 밀폐됨에 따라 흡기 부압을 발생시키는 부압 호스 및 상기 연료 주입구에 삽입되고, 상기 부압 호스에서 발생되는 흡기 부압에 따라 작동하여 상기 부압 챔버의 밀폐 상태를 고정시키며, 상기 엔진의 시동 종료 시 작동 해제되어 상기 연료 주입구에서 분리되도록 형성되는 연료 캡을 포함한다.
