Concept Design of a Quick Response System to Avoid Fatalities in Post-Collision Fire Due to Fuel-Tank Damage

This paper is an attempt to address one of the causes of catastrophic failures attributed to incidents of fire and smoke in commercial vehicles during last few years in China and India which have resulted in a considerable number of casualties. Some of the accidents encountered happened because of a crash with fire originating from the fuel tank. This was attributed to fuel leakage and excessive heat produced due to friction of debris with the fuel tank which happened within a few seconds of the crash. A Fuel-Tank Safety ECU for preventing such fire-mishaps shall be designed for spotting this failure and activating prevention methods in order. This ECU shall process the data coming from temperature-sensor and fuel-pressure sensor placed on the fuel tank of the vehicle. This real-time data shall be compared with the previously computed values and then the delta-differentiated value shall be used to conclude the likelihood of a fire-occurrence.
