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.

    A system for cleaning a fuel cap valve of a vehicle, may include a fuel cap having an air breather passage and a negative-pressure valve body configured for opening or closing the air breather passage; a canister for collecting evaporated gas inside a fuel tank to supply the evaporated gas into an engine intake system; and a negative-pressure control mechanism for controlling an engine negative pressure, which is applied from the engine intake system to the negative-pressure valve body of the fuel cap through the canister and the fuel tank, to reach a predetermined level or more, or for controlling the engine negative pressure at a repetition interval, in a fuel cap cleaning mode for cleaning the negative-pressure valve body of the fuel cap.
