Abstract

고정밀도로 연료 증산 방지 장치의 고장을 진단할 수 있는 연료 증산 방지 장치의 고장 진단 장치를 제공한다.
연료 탱크의 내부 압력을 소정의 초기 압력으로 조정하는 초기화 수단과, 대기구멍을 닫으면서 퍼지 제어 밸브를 구동하여 초기 압력을 소정의 목표 압력까지 변화시킴과 함께 이때의 퍼지량을 일정 유량으로 제어하는 압력 조정 수단과, 연료 탱크의 내부 압력이 목표 압력에 달하였을 때 퍼지 제어 밸브 및 대기구멍을 함께 닫음으로써 연료 증산 방지 장치에 밀폐 구간을 구성하는 밀폐화 수단과, 밀폐 구간에 설치된 압력 검출 수단과, 밀폐 구간의 내부 압력의 변화에 의거해 연료 증산 방지 장치의 고장 진단을 고장 진단 수단을 구비했다.
