Abstract

본 발명은 연료탱크로부터 인젝터까지의 연료공급 시스템에 대한 내구성의 시험에서 설정된 소정의 조건이 경과하기 전에 연료펌프나 연료 파이프의 연결부, 연료 파이프의 연료공급정도, 인젝터등으로부터 이상이나 시험장치의 이상이 검출될시 검출된 정보를 표시수단에 디스플레이한후, 시험장치의 동작을 자동으로 중지시켜 시험장치의 부하발생을 방지하므로 연료공급 시스템의 내구성 시험에 신뢰성이 제공된다.The present invention relates to an abnormality from the fuel pump or the fuel pipe connection, the fuel supply accuracy of the fuel pipe, the injector, or the like before the predetermined condition set in the durability test for the fuel supply system from the fuel tank to the injector is passed. When the detected information is displayed on the display means when this is detected, the operation of the test apparatus is automatically stopped to prevent the load of the test apparatus, thereby providing reliability in the durability test of the fuel supply system.
