Abstract
A fuel safety control device includes a fuel pump disposed in a fuel tank and coupled to a vehicle engine with a fuel piping system, a fuel system safety controller coupled to the fuel pump for controlling the driving direction of the fuel pump, and an impact detector coupled to the fuel system safety controller for supplying an impact signal to the fuel system safety controller and to reverse the driving direction of the fuel pump, and to draw the fuel from the fuel piping system back to the fuel tank when receiving an impact signal, in order to prevent the impact firing from being occurred. A transformer circuit may be coupled to the fuel pump for increasing the driving speed of the fuel pump when required.
