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.

More than five thousands transportation fires occurannually in Korea and the resulting destruction of property and loss of life is huge and results in traffic and environmental pollution. The recent development of automobile technology such as the hybrid concept and use of bio fuels makes fire protection even more difficult due to a lack of understanding of the new adapted system including vehicle engines. In this study, a numerical simulation was performed on a PSR (perfectly Stirred Reactor) to simulate an automobile engine and to clarify the effect of gasoline/ethanol surrogates as a fuel. The temperature, NOx and soot emissions were predicted to decrease with increasing ethanol content, but that of unburned hydrocarbons was found to increase dramatically. The result will provide not only the basic thermal characteristics for engines and their after-treatment systems, but also make it possible to assess the potential for fire events in these systems when an ethanol mixed fuel is used in gasoline vehicles.

As a result of the enforced control of emission, many devices, including the diesel particulate filter, have been installed in diesel cars to reduce the emission of particulate matters. In this study, a car fire case has been investigated and analyzed. A car fire broke out after the vehicle traveled a distance of 1.4 km from a car service center. The car was provided with DPF cleaning when the DPF warning light came on. After being dismantled in the engine room, the car's engine and gearbox were investigated. The findings showed that the rear part of the DPF metal case was melted and punctured, while the honeycomb filter of the DPF was damaged. The car fire was caused by an overheated DPF associated with inaccurate maintenance practice. Therefore, the responsibility of the fire rested on the car service center that performed the DPF cleaning.

Using high tensile steel plate makes the vehicle body stiffness lower even though it can lessen the fuel consume rate in application of weight reduction. The crack which happens arround vehicle window glass is brought about due to fatigue with low torsional stiffness. The paper presents a most suitable way to increase torsional stiffness using elasticity theory. Also the result of this study shows good agreement with FEM and experiments. We used a passenger car for calculation in this paper. Because we can apply the result of this study to fire engine as well as passenger car.

This paper is to analyze and study the failure examples of fire by inflammables and electric contact faulty in interior of vehicle. The first example, the driver used to air freshener that remove the air conditioner bad smell. He get out of a car. And then, he put it on the crash pad. Before long, a fire breaks out because of explosion solar radiation. The second example, the driver used in room of a car. It certified the fire by disconnection phenomenon happened the electric overload. The third example, the driver install the heat rays to warm his body, In the initial stages, it didn't seek the dangerous of fire during using a car to 5,000km. This heat rays become to down durability so that produced the electric overload in an instant. The fourth example, after the man smoked the cigarette on riding with rear seat, he put it on seat in vehicle no extinguishing the burning cigarette. It knew the fact that burnt to ashes a car by on well combustible paper. Thus, the driver must consider a countermeasure for minimize the fire production when he use the inflammable and install adding electric system.
