Study of Fire Examples for Electrical Wire Short and Insulated Coating Melting by Heating Including Automotive Engine Room

Abstract

This paper is to analyze and study the cause of fire examples produced because of short phenomenon by electric connecting damage and contacting engine overheating 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.
