Abstract

본 발명은 차량이 주행 및 정지시에는 물론 연료를 처음 주입할 때 발생하는 과다한 증발가스를 저감시켜 주기 위하여 기존의 캐니스터와 연계되도록 캐니스터 (10)을 별도로 장착하여 연료주입시 발생하는 증발가스에 대한 연료보급을 캐니스터로 증발가스 제어를 위해 베이퍼 벤트 밸브(12)가 구성된 연료탱크와 퍼지 솔레노이드 밸브에 증발가스관(11)(11')으로 연결시켜 엔진의 상태를 체크하는 각종 센서들에 의한 정보를 입력하고 연산하여 최적의 구동신호로 출력하는 E.C.U에 의해 제어되도록 함으로서 연료주입시 차량의 증발가스를 저감시킬 수 있게 한 장치를 제공코저 한 것이다.In order to reduce excessive evaporation gas generated when the vehicle is running or stopped, as well as when fuel is injected for the first time, the canister (10) is separately installed to be connected to the existing canister, The fuel supply is connected to the fuel tank and the purge solenoid valve constituted of the vapor vent valve 12 for controlling the evaporation gas to the canister by the evaporation gas pipes 11 and 11 ' And a control unit that controls the fuel injection valve to be controlled by an ECU that inputs and computes an optimum driving signal and outputs the optimal driving signal.
