Abstract

본 발명은 연료탱크의 리크 진단 방법 및 이에 적용되는 장치를 개시한다. 본 발명에 따른 연료탱크의 리크 진단 방법은, 주행 중 차량의 연료탱크에 대한 압력을 연료탱크의 리크 진단 압력으로 조절하고 차량 정지 시에 곧바로 연료탱크에 대한 리크 진단을 수행할 수 있도록 하기 위한 구성으로 이루어진다. 따라서, 본 발명은 차량 정지 전에 미리 차량의 연료탱크에 대한 압력을 연료탱크의 리크 진단압력으로 조절하고 차량이 정지하면 차량이 정지하고 있는 동안에 부합 형성이 불가한 경우 또는 진단률을 높여야 하는 경우 등의 상황이 발생하여도 연료탱크의 리크 여부에 대한 진단을 용이하게 수행할 수 있다.연료탱크에 대한 리크 진단을 수행할 수 있다.
