A device for reinforcing a vehicle fuel tank improves a structure of a rigid reinforcement pillar mounted in an enclosed fuel tank by maintaining stiffness of the reinforcement pillar in a state in which the fuel tank is under positive pressure and an engine negative pressure acts thereon as well as inducing breakage of the reinforcement pillar when a large impact applies, such as in the event of vehicle collision, thereby preventing a fused portion between upper and lower plates of the fuel tank from rupturing.
一种用于加强车辆燃料箱的设备,通过在燃料箱处于正压并且发动机负压作用于燃料箱上的状态下保持加强柱的刚度以及致使加强柱在诸如车辆碰撞情况下施加较大冲击时发生断裂而改善安装在封闭式燃料箱中的刚性加强柱的结构,由此防止燃料箱的上板与下板之间的融合部出现破裂。
