The fire outbreaking origin of vehicle fire would be classified into two positions such as engine room and passenger room of vehicle. As a firewall is installed between engine room and passenger room, in case of engine fire, it could be assumed that it takes about 10 to 15 minutes for the fire to spread into passenger room There are two different vehicle engine layouts such as transversal and lateral layout, and the fire spreading process and resulting damage patterns on left and right side dash-panel are different depending on the engine layouts. In accordance, the first thing to do for correct and speedy finding of the fire origin place is considered to be an investigation into the dash-panel damage in case of engine room fire investigation.

Control devices for fire safety systems located in a engine room are to be arranged at a safe position which is easily accessible during a fire. To develop an interpretation for the safe position in engine rooms, calculation and experiments are carried out to determine a correlation between radiant heat and distance from fire in this paper. On the basis of results of this research, the control devices for a main engine are to be installed in the behind side of an obstruction to reduce radiant heat from the fire of the main engine. In case of other control devices, they are also to be provided in the same manner of control devices for the main engine or are to be placed with 5 meters far from fire hazards.

In this study, tests were conducted to establish a fire engine of relay waterproof and utilization in order to maintain the pressure in a situation that require high-pressure water-resistant such as a high-rise building fire, etc. As a result of test on the change of a relay waterproof pressure, the measurement result with the hydrant intake of a fire engine opened has reduced approximately 20 % compared to the measurement result with the hydrant intake closed. Similar efficiency showed in the test result that change the pressure of 2 fire engines respectively to use them more efficiently at a fire fighting activity site. A fire engine operation and utilization is proposed based on this study result in order to cope effectively with a fire site requiring high-pressure stream in a high-rise building fire, etc. by using a fire engine held at present because there is no fire pump with high-pressure stream ability arranged at the fire station and there is no regulation on high-pressure fire-fighting pumps in a type approval and verification technology criterion for a fire engine.

Extinguishing a fire at an early stage is most important to prevent spreading of a fire in Unmanned Engine Room. The most proper fire extinguish system was analyzed after examining the Automatic spread Extinguish System, which is mostly installed in Unmanned Engine Room, reproduced in the condition of real Unmanned Engine Room.

Although it is widely accepted that a fire can occur due to electrical causes even when an engine stops, there is little introduction of detailed case analysis. This study analyzed a fire case caused by an electrical cause during engine stopping at parking lot in detail. Moreover, it was revealed that the fire was mainly caused by design defect.

There is fire dangers inside engine bay where fuel of oil leakge can be ignited by hot engine surfaces. So, Fire suppressor is needed to extinguish the flames. The current FAA requirement is that the concentration level should be greater than 6% by volume throughtout the protected zone for longer than a half second simultaneously. To Satisfy the FAA requirement, The Fire extinguish system should quickly delivery the fire extinguish agents and Fire extinguish system should be designed effectively. This study is to develop and simulate the injection of fire extinguish agents into the engine-bay. Transient simulations were performed and predicted the concentration of fire extinguish agents at the certain locatioin in the engine-bay.

In this paper, the fire engine pump is controlled and monitored by the AJAX (Asynchronous Javascript and Xml) in the web server. The embedded system with built-in system having a processor and a memory of high performance occurs many problems in transmitting the large amount of data in real time through the web server. The AJAX is different from HTML (Hyper Text Makeup Language) with java script technology and can make RIA (Rich Internet Application). It process the necessary data by using asynchronous and it take advantage of usefulness, accessibility, a fast response time. Using AJAX can build up web server with real time and monitoring that fire engine pump status, check processing pump memory in the event of fire, also remotely monitors can do. The web server system can control the fire engine pump as like the black box. The experimental results show the effectiveness and commercialize possibility.

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.

Our goal was to make a cost-effective automatic fire extinguishing system for the engine compartment use of automobiles. We designed this system for the engine compartment. This system consists of 1)foam extinguisher, 2)four nozzles, 3)a pipe arrangement, and 4)an extinguishing device which is equipped with a glass bulb as detector. First and foremost, the extinguishing device was carefully designed to keep the system cost to a minimum. Second, a AFFF foam extinguisher was used because no other fire-fighting agents proved effective against fire in the engine compartment. The AFFF(Aqueous Film Forming Foam) agent which was used in the extinguisher is the 3M company's Light Water. We sought, however, to make other foams by using Halon 1301 and Halon alternatives such as HCFC Blend A, HFC-227ea. We selected these alternatives instead of air in order to raise the expansion ratio of the AFFF agent. By these means we discovered that it is possible to increase the expansion ration of the AFFF agent up to 44:1. We then demonstrated that our automatic fire extinguishing system is the most effective and lowest cost-system yet devised for passenger cars.

In the event of fire, it is necessary to put out the fire within a golden time to minimize personal and property damages. To this end, it is necessary for fire engines to arrive at the site quickly. This study established a fire engine travel time estimation model to secure the golden time by identifying road and environmental factors that influence fire engine travel time in the case of fire by examining data on fire occurrence with GIS DB. The study model for the estimation of fire engine travel time (model 1) covers variables by applying correlation analysis and regression analysis with dummy variables and predicts travel time for different types of places where fire may occur (models 2, 3, 4). Analysis results showed that 17 siginificant independent variables are derived in model 1 and the fire engine travel time differs depending on the types of places where fire occurs. Key variables(travel distance, number of lane, type of road) that are included commonly in the 4 models were identified. Variables identified in this study can be utilized as indicators for research related to travel time of emergency vehicles and contribute to securing the golden time for emergency vehicles.
