초록

논문은 대형트럭의 화재에 관련된 고장사례를 고찰한 논문이다. 첫 번째 사례는 6번 실린더 라이너 상단부와 실린더 헤드 사이에 접촉하는 D링부의 변형으로 헤드 가스켓부의 기밀불량 현상으로 냉각수가 누출하여 엔진이 과열되었다. 이 열이 에어크리너 주변 배선에 전달되어 쇼트(short)에 의해 화재가 발생된 것을 확인하였다. 두 번째 사례는 자동차의 리어(Rear) 4축 브레이크 라이닝 과다마모로 브레이크 작동 S 캠(Cam)이 리턴되지 않아 브레이크 라이닝이 드럼과의 계속적인 마찰에 의한 마찰열에 의해 화재가 발생된 것을 확인하였다. 세 번째 사례는 엔진 점검을 위해 캡을 틸팅하였을 때 틸팅 모터의 과부하로 배선의 단락현상이 발생하여 이 불꽃에 의해 화재가 발생한 것을 확인하였다. 따라서, 대형트럭의 화재는 철저한 관리를 하여 화재발생을 최소화하여야 한다.

This paper is a purpose to study the failure example for heavy-duty vehicle fire. The first example, the researcher found the engine over-heating phenomenon causing a coolant leakage by the sealing poor of head-gasket because of D-ring part deformation contacting with cylinder liner top-part and cylinder head. He certified a fire breakout by short transferred to surrounding wiring of air-cleaner. The second example, a brake lining by return fault of break operating S cam causing with much wear of a rear 4 wheel brake lining repeatably was worn by friction. In the long run, it became the cause of fire. The third example, the researcher knew the fire cause was came about the short of wire by overload of tilting motor when the driver tilted up the cap to inspect a engine. Therefore, a heavy-duty fire must minimize the fire occurrence by thorough controlling.
