Ⅱ. Object of Study
For a fire take places heat or flame(source of fire), material that can generates combustion reaction(combustibles) and enough oxygen for combustion should be provided. In case of the vehicle it is loaded with liquid fuel and combustible that generates heat continuously and has the high inflammability due to the characteristic of engine. Therefore it has the characteristic that it is highly exposed to the fire everytime and everywhere and rapid combustion is expanded if a fire occurs. If a fire occurs during driving it is very difficult to extinguish it because of the condition of the road, weather and other different reasons and it can be connected to major accident because rapid escape in the small space is difficult. Such a worry actually came true and connected to disaster with many casualties as we saw in the accident of SeoHae Grand Bridge in 2006.

According to the analysis data on property damage per places in the first half of 2011, vehicle fire comprises 8% of total fire cases (11,155Mil.Won). And for only June 2011, vehicle fire occurred 2,100cases which are about 38.5% increased compared to 1,547cases in the previous year. Therefore it is judged that we have to investigate the reason of a fire thoroughly and any measure for the prevention of the fire shall be taken in order to decrease the vehicle fire. The occurrence of vehicle fire can be attributed mainly to 4 reasons including the fire from car accident.
(1) vehicle fire from the short of electrical equipment
(2) vehicle fire from overheat of engine
(3) vehicle fire from abnormal combustion
(4) vehicle fire from exhaust heat and friction heat

Every year big or small vehicle fire occurs and will occur whether it is from 4 reasons mentioned above, defect of vehicle itself or secondary result by car accident. And it will threaten our precious life and property continuously. Many researches and product developments for vehicular fire extinguishing system are carried out throughout the world. But most technologies have much similarity and those technologies mainly rely on actual electrical signal in case of car accident. But fire extinguishing system can't operate well in case that there is a problem in the delivery of electrical signal due to major exterior shocks or serious damage in the engine part of the vehicle. Also it is very insufficient and early stage for the extinguishing agent that can suppress the fire in vehicle engine. It is also difficult to suppress the fire in vehicle with gas or powder type extinguishing agent when we consider the density of the space inside of vehicle bonnet such as engine, air conditioner duct and radiator.
Accordingly this study is aiming the development of extinguishing agent that is having the type of foam with the particular space absorbent and time stationary and can suppress the fire in engine efficiently. Foam-type extinguishing agent shall penetrate into the space of engine inside of bonnet and do extinguishing process such as suffocation and cooling against a fire. For the suppression of the fire in engine this extinguishing agent shall be type of shaving cream or hair mousse from the mixture of water and surfactant or discharging agent.

After we investigate the development status for vehicular extinguishing agent we found that there has been many achievements in the development of discharging equipment and we could see many contents about the discharging method of extinguishing agent and storage method of extinguishing agent but the development of extinguishing agent is very little and it is very difficult to look for any example of development for extinguishing agent. The extinguishing agent is mainly concentrated on gas or foam type and we think these agent has the limit in its fire suppression capability.

Considering the status mentioned above this study concentrates on the development of high-capacity fire extinguishing agent that suppress a fire in engine efficiently and establish the idea about the development of fire extinguishing system that automatically discharges extinguishing agent by the shock from crash and the temperature in engine. When we investigate the most accidents regarding harmful gas in the car we found several causes; Driver or passenger's sleeping with the car is in starting-up status which eventually reaches to deadly injury or death due to carbon-monoxide intoxication that is flown into the inside of the car. Or making suicide by making a fire with briquet which is actual situation.

So the main object of this study is to develop more safe vehicular system by combining harmful gas accident prevention system and vehicular automatic fire extinguishing equipment in order to look for the basic solution about the engine fire and prevention of accidental accident that occurs in the car. Object of study in this case is divided into 3 subjects.

1. Development of automatic window open & close system and development of control module that can detect harmful gas in the car and reduce person's damage by suffocation.
2. Development of automatic fire extinguishing equipment that can suppress a fire in the engine through the detection of shock from crash/collision and the temperature of engine room.
3. Development of the best optimized extinguishing agent that can suppress a fire in engine more efficiently.
