Abstract

This paper deal with vehicle fire caused by damage of diesel particulate filter (DPF) on diesel passenger vehicles. In order to reduce particulate matters included exhaust gases, a DPF in the exhaust system were installed diesel vehicles. A DPF was broken by excessively trapped particulate matters, regeneration error with a malfunction of ECU and defect of suction system such as swirl valve. If the DPF was broken, hot exhaust gases was released to the bottom of vehicle and released hot exhaust gases lead to occur the fire through combustible materials around the exhaust system. When a fire happened in the diesel vehicle caused by damage of DPF, silicate inorganic compounds were attached to the exhaust ventilation pipe and muffler. The silicate inorganic compounds were created by DPF combustion consisting of raw material ceramics. If the silicate inorganic compounds attached to the tail pipe in the diesel passenger vehicles, its fire cause will be assumed damage of DPF.

본 논문에서는 디젤 승용차량에서 매연저감장치 손상에 기인한 차량화재에 대하여 기술하였다. 디젤 차량에서는 배출가스에 포함되는 입자상 물질을 저감하기 위하여 매연저감장치를 배기계통에 설치하고 있다. 매연저감장치는 입자상 물질의 과다 포집, 재상과정에서의 오류 및 흡기계통 불량 등에 의해 재생과정에서 파손에 이르게 되며, 매연저감장치가 파손되는 경우, 고온의 배출가스가 분출되고, 차량 하부 배기계통의 주변 가연물을 통해 화재로 진전된다. 매연저감장치 손상에 의해 화재가 발생되는 경우, 배기계통 배관 및 머플러 부분에 규산염계 무기화합물이 부착되는 특징을 나타내며, 이 규산염계 무기화합물은 매연저감장치 내부 필터 재료인 세라믹 부분이 손상되는 과정에서 발생된다. 따라서 화재가 발생된 디젤 차량의 경우, 머플러 주변에서 규산염계 무기화합물이 식별되는 경우, 매연저감장치 손상에 기인한 화재로 추정할 수 있다.
