A safety apparatus for a fuel tank in a vehicle includes a fuel tank for storing fuel, a gelling agent tank for storing a gelling agent which can gelatinize the fuel, a supply system for supplying the gelling agent in the gelling agent tank to the fuel tank, a tank-emergency detecting system for detecting an emergency in the fuel tank, and a control system for outputting a drive signal to drive the supply system. The control system outputs the drive signal under the condition that the tank-emergency detecting system outputs an emergency detection signal indicating an emergency in the fuel tank.

A safety apparatus for a fuel tank in a vehicle comprising: a fuel tank for storing fuel; a gelling agent tank for storing a gelling agent which can gelatinize the fuel; a supply system, connected between the gelling agent tank and the fuel tank, for supplying the gelling agent in the gelling agent

A safety apparatus for a fuel tank in a vehicle comprising: a fuel tank for storing fuel; a gelling agent tank for storing a gelling agent which can gelatinize the fuel; a supply system, connected between the gelling agent tank and the fuel tank, for supplying the gelling agent in the gelling agent tank to the fuel tank; tank-emergency detecting means, coupled to the fuel tank, for detecting an emergency in the fuel tank and for outputting an emergency detection signal indicating said emergency; a control means, coupled to the supply system and the tank emergency detecting system, for outputting a drive signal to drive the supply system; wherein the control means outputs the drive signal under the condition that the tank-emergency detecting means outputs the emergency detection signal, wherein the tank-emergency detecting means comprises: an optical fiber provided on one of the fuel tank and a component that is attached to the fuel tank, a light supply means, coupled to the optical fiber, for supplying a predetermined quantity of light to the optical fiber, and a light quantity detecting means, coupled to the optical fiber, for detecting the quantity of the light which was transmitted from the light supply means through the optical fiber; wherein the emergency detecting means compares change of the quantity of the light which is transmitted through the optical fiber when no large external force is applied to the fuel tank to change of the quantity of the light which is transmitted through the optical fiber when a large external force is present on the fuel tank and detects an emergency in the fuel tank on the basis of the results of the comparison; and said safety apparatus further comprising a plurality of emergency detection means, including (1) a temperature-emergency detection means for detecting temperature in the fuel tank and outputting an emergency detection signal when the temperature in the fuel tank exceeds a predetermined threshold value of temperature; and (2) an acceleration-emergency detection means for detecting acceleration and outputting an emergency detection signal when the acceleration exceeds a predetermined threshold value of acceleration; and wherein the control means outputs the drive signal, under the condition that at least one of the plurality of emergency detection means outputs an emergency detection signal.
