The plastic high-pressure fuel tank comprises a fuel tank shell, a fuel pump and an oil filling pipeline, and an oil storage cavity is formed in the fuel tank shell; the fuel pump is arranged at the middle position in the oil storage cavity; the oil filling pipeline is arranged on one side of the oil tank shell and extends into the oil storage cavity; a plurality of first wave-proof plates are vertically arranged on the outer side of the fuel pump in the oil storage cavity; a fixing plate is arranged at the top of the first wave-proof plate; the first wave-proof plate is arranged in a wave shape in the vertical direction; a second wave-proof plate is arranged in the middles of the first wave-proof plates in a penetrating manner; an oil storage groove is formed in the oil tank shell opposite to the fuel pump; an oil storage bowl is fixedly arranged outside the oil storage tank; a plurality of oil leakage holes are circumferentially formed in the bottom of the oil storage bowl; a plurality of oil passing ports are circumferentially formed in the middle of the oil storage bowl. According to the fuel tank, the multiple first wave-proof plates are arranged in the width direction and the length direction of the fuel tank shell, gasoline in the fuel storage cavity is separated in the transverse direction and the longitudinal direction, and noise caused by sharp collision between the gasoline in the fuel tank and the fuel tank in the automobile running process is reduced.
塑料高压燃油箱,包括油箱壳体、燃油泵、加油管道,油箱壳体内设置有储油腔;燃油泵设置于储油腔内中部位置;加油管道设置于油箱壳体一侧延伸至储油腔内;储油腔内于燃油泵外侧竖直设置有多个第一防浪板;第一防浪板顶部设置有固定板;第一防浪板在竖直方向上为波浪形设置;多个第一防浪板中部贯穿设置有第二防浪板;油箱壳体相对燃油泵位置设置有储油槽;储油槽外侧固定设置有储油碗;储油碗底部周向设置有多个漏油孔;储油碗中部周向设置有多个通油口。本发明通过多个第一防浪板于油箱壳体的宽度方向和长度方向设置,将储油腔内的汽油在横向与纵向分隔,降低汽车行驶中燃油箱内汽油与燃油箱刺鼻撞击出现的噪音。
