The heavy truck fuel tank comprises a tank body, and the inner wall of the tank body comprises a top wall, a bottom wall, a front side wall and a rear side wall, the top wall and the bottom wall are oppositely arranged in the vertical direction of a heavy truck, and the front side wall and the rear side wall are oppositely arranged in the longitudinal direction of the heavy truck. The uphill oil blocking structure is connected to the bottom wall in a sealed mode, and when the front side wall is higher than the rear side wall, the uphill oil blocking structure can block fuel oil from flowing backwards. The downhill oil blocking structure is connected to the bottom wall in a sealed mode, and when the front side wall is lower than the rear side wall, the downhill oil blocking structure can block fuel oil from flowing forwards. And the oil absorption structure is arranged on the box body, and an oil absorption opening of the oil absorption structure can absorb oil blocked by the uphill oil blocking structure and oil blocked by the downhill oil blocking structure. According to the fuel tank for the heavy truck, when the truck is in an uphill and downhill working condition, the uphill oil blocking structure and the downhill oil blocking structure can be used for blocking collected fuel oil to ensure that the oil suction port of the oil suction structure is in full contact with oil liquid, so that the hidden danger of insufficient power or even flameout of the truck is reduced; meanwhile, the fuel oil utilization rate is increased, the endurance mileage of the vehicle is increased, and then the customer satisfaction is improved.

    本申请提供了一种重卡燃油箱,包括箱体,其内壁包括用于沿重卡的垂向相对设置的顶壁和底壁以及用于沿重卡的纵向相对设置的前侧壁和后侧壁;上坡阻油结构,密封连接在底壁上,当前侧壁高于后侧壁时其能够阻挡燃油向后流;下坡阻油结构,密封连接在底壁上,当前侧壁低于后侧壁时其能够阻挡燃油向前流;吸油结构,设置在箱体上,吸油结构的吸油口能够吸取上坡阻油结构阻挡的油以及下坡阻油结构阻挡的油。该重卡燃油箱在车辆处于上下坡工况时,能够利用上坡阻油结构和下坡阻油结构阻挡后收集的燃油,来保证吸油结构的吸油口与油液充分接触,进而降低车辆发生动力不足甚至熄火的隐患;同时提高燃油利用率,增加车辆的续航里程,进而提升客户满意度。
