Abstract

PURPOSE: A fuel feed shutoff system prevents the occurrence of a fire by breaking the supply of fuel on a head-on collision of a vehicle. CONSTITUTION: A fuel feed shutoff system comprises a fuel shutoff valve(8), a resistance wire(5), a resistance gauge(6) and an electronic control unit(7). The fuel shutoff valve(8) mounted on one side of the center of a fuel pipe(2) breaks the supply of fuel. The resistance wire(5) is mounted to cross an engine room(4) between an engine(1) and a fuel filter(3). The resistance gauge(6) mounted on one side of the resistance wire(5) measures the resistance value of the resistance wire(5) and inputs the measured resistance value to the electronic control unit(7). When the engine(1) pulls backward an impact coming from the head-on collision of a vehicle, the resistance wire(5) extends the engine(1). The resistance value of the resistance wire(5) is increased by the extension of the resistance wire(5). The electronic control unit(7) operates the fuel shutoff valve(8) to break the supply of fuel from a fuel pump(10) to the engine(1) when the resistance value of the resistance wire(5) inputted from the resistance gauge(6) is above constant value.
