The present invention relates to a system for cleaning a fuel cap valve for a vehicle, which is able to remove foreign matters fitted into a fuel cap valve by using a negative pressure of an engine. Thus, the present invention provides the system for cleaning a fuel cap valve for a vehicle, which is able to remove foreign matters fitted in a negative pressure valve body by dropping the foreign matters without additionally installing parts such as a mesh filter or the like in the fuel cap, controlling the negative pressure of the engine by a predetermined cycle for supercharging air into a negative pressure valve body of the fuel cap, or providing a chattering effect such that opening and closing operation of the negative pressure valve body of the fuel cap can be repeated, thereby easily removing foreign matters from the negative pressure valve body.
본 발명은 연료캡 밸브에 끼이는 이물질을 엔진 부압을 이용하여 제거할 수 있도록 한 자동차용 연료캡 밸브 크리닝 시스템에 관한 것이다. 즉, 본 발명은 연료캡에 메쉬 필터등과 같은 부품을 추가 장착하지 않고, 엔진 부압을 소정의 주기로 제어하여 연료캡의 부압밸브체에 대기 과급이 이루어지게 하거나, 연료캡의 부압밸브체에 열림 및 닫힘 작동을 반복하는 채터링 효과를 부여함으로써, 부압밸브체에 끼인 이물질을 탈락시켜 제거할 수 있도록 한 자동차용 연료캡 밸브 크리닝 시스템을 제공하고자 한 것이다.
