The high-pressure fuel tank system comprises a fuel tank body, an upper shell and a lower shell are arranged on the fuel tank body, a fuel pump assembly is installed at the upper end of the upper shell, an oil supply pipe assembly is further installed on the upper shell, an FTIV is jointly arranged on the side face of the upper shell and the side face of the lower shell, and the FTIV is connected with the fuel pump assembly. A first wave-proof plate and a second wave-proof plate are installed in the fuel tank body, an LVS with a labyrinth structure inside is further arranged on the outer side of the fuel tank body, an LVS air inlet and an LVS air outlet are formed in the two ends of the LVS respectively, the LVS air outlet is higher than the LVS air inlet, and it is guaranteed that fuel can flow back into the fuel tank. The wave-proof plate is arranged in the high-pressure fuel tank system with the zero shaking leakage rate, so that the shaking amplitude and frequency of fuel oil caused by acceleration, braking and bumping processes of a vehicle can be reduced.

    本发明公开了一种零晃动泄漏量高压燃油箱系统,包括燃油箱本体,所述燃油箱本体上设有上壳体和下壳体,所述上壳体上端安装有燃油泵总成,且上壳体上还安装有供油管总成,并且上壳体和下壳体侧面共同设有FTIV,所述燃油箱本体内安装有第一防浪板和第二防浪板,且燃油箱本体外侧还设有内部带有迷宫结构的LVS,且LVS两端分别设有LVS进气口和LVS出气口,并且LVS出气口高于LVS进气口,保证燃油能够回流到燃油箱内。该零晃动泄漏量高压燃油箱系统内设置了防浪板,可以减少由于车辆加速、制动和颠簸过程导致的燃油晃动幅度和次数。
