Auto fire detection & fire extinguisher system in all cars - why not? The recent news of Racer Ashwin Sundar and his wife losing their lives in a burning BMW shook many of us and it indeed makes us wonder how come incidents like these can happen in these modern times. A similar thought kept lingering among many of us when Paul Walker succumbed in a burning Porsche. There was also a Jetta(of a Team-Bhpian) which went on flames just about a month back. Just a quick internet search reveals that there are around 400,000 car-catching-fire cases reportedly.
Nowadays, even mass market cars are becoming increasingly powerful and agile and it is a necessity to create a system to avoid such incidents in future. Yes, things like Fuel cut off in case of a collision is there, but these incidents show they are not enough.
Getting straight to the point, I'm wondering why not manufacturers think on the following lines. Most of the "car catching fire" videos I saw indicate that in most cases fire starts from the engine bay, so I had the following few ideas: Idea 1 - Just a crude thought
- Design and strategically place Fire extinguishers(like the hand held ones with either liquid or dry compounds, which we see in offices) in the four corners of the engine bay and have sensors that trigger them when they sense fumes and fire.
Advantages
- Till this system gets really engineered well, it may not be able to dose off the fire entirely but it might delay the fire and provide those crucial extra minutes.
Disadvantages
- In case of head on collision where the engine bay gets crushed, the system may not work effectively. Idea 2
Like the fuel tank, have a reservoir that carries the Fire extinguisher compound. Have Pipes that run around the engine bay in 3 layers - one layer on top, one in the middle and one at the bottom. Have sensors to identify fumes and flames, and small motors to jet propel the compounds from the reservoir and across across the pipes and from there across the engine bay.
Advantages
- A far more refined and effective method than the first method and can be far more effective even in case of head on collisions.
Disadvantages
- Probably cost and overhead for manufacturers.
In both the methods, there can also be a override switch where the driver can trigger the system in case of a collision and he is conscious and senses that a fire might break out.
So the question is - Why not think on these lines as a first step?
