초록

이 논문은 자동차 엔진룸에서 전기적인 접촉불량에 의한 단락현상과 엔진의 뜨거운 열에 의해 가연성 물질과 접촉하여 화재가 발생된 원인을 분석하고 연구하는 것이다. 첫째, 배터리에서 시동모터로 연결되어 있는 배터리 전원선이 자동변속기 상단에 배선을 고정시켜 주는 브래킷(Bracket) 볼트 이완으로 차체와의 단락 현상에 의해 화재가 발생된 것을 확인하였다. 둘째, 배터리에서 시동모터까지 가는 배선에 감은 절연테이프가 녹아 단락현상에 의해 화재를 일으킨 것을 확인하였다. 셋째, 냉각 팬 배선이 이완되어 과열된 엔진의 열에 의해 배선이 융착되어 화재가 발생된 것을 확인하였다 따라서, 엔진에 관련된 시스템의 화재는 엔진 및 각 시스템의 손상으로 자동차 탑승객을 위험에 처하게 하며, 화재 후 자동차는 재사용이 어렵게 되므로 시스템의 철저한 관리와 세심한 주의가 요구되어진다.

This paper is to analyze and study the cause of fire examples produced because of short phenomenon by electric connecting damage and contacting engine over-heating with combustible materials in engine room of vehicle. In the first example, it knew the fact that the fire produced by contacting with body of vehicle because of loosed of bracket bolt for wire fixing that installed on the transmission case the battery power cable supply the power from battery of engine room to starting motor. In the second example, it certified the fire by short phenomenon because of insulation tape melting wound wiring lined from battery to starting motor. In the third example, it sought for fire's cause that melting phenomenon the wire coating by overheated engine as the wire disconnected with connector by the vibration. Therefore, the fire of system including engine electric made in the danger the people in the car by failure of engine and other system. And than, the car's driver must manage and examine a vehicle conscientiously.
