[0025] The plastic fuel tank body 1 has multiple sets of mounting blocks 2 inside, three sets of first-stage anti-surge baffles 21 inside, and multiple sets of second-stage anti-surge baffles 23 inside. The lower ends of the three sets of first-stage anti-surge baffles 21 are all provided with multiple sets of assembly slots 22. The multiple sets of second-stage anti-surge baffles 23 are arranged crosswise with the first-stage anti-surge baffles 21 through the multiple sets of assembly slots 22. The lower ends of the multiple sets of mounting blocks 2 are respectively fixed to the upper ends of the three sets of first-stage anti-surge baffles 21, and the upper ends of the multiple sets of mounting blocks 2 are all fixed to the inner top of the plastic fuel tank body 1.

[0026] The specific settings and effects of the present embodiment are as follows: the fuel pump 12 is installed at the upper end of the plastic fuel tank body 1 and is used to deliver fuel from the plastic fuel tank body 1 to the engine. The fuel pump 12 can dynamically adjust its output flow according to the received control signal, thereby realizing accurate control of the fuel supply amount.

[0027] Part of the liquid level sensor 15 is fixed to the plastic fuel tank body 1, and the other part is arranged inside the plastic fuel tank body 1, which is used to monitor the fuel level in the fuel tank in real time and convert the liquid level information into an electrical signal output.

[0028] Part of the pressure sensor 16 is fixed to the plastic fuel tank body 1, and the other part is arranged inside the plastic fuel tank body 1, which is used to monitor the pressure change of the fuel and feed back the pressure signal to the electronic control unit 17.

[0029] The electronic control unit 17 is electrically connected with the fuel pump 12, the liquid level sensor 15 and the pressure sensor 16. The electronic control unit 17 receives signals from the liquid level sensor 15 and the pressure sensor 16, and communicates with the engine control system of the vehicle to obtain the operating condition information of the vehicle, such as vehicle speed, engine speed, throttle opening, etc. According to these information, the electronic control unit 17 calculates the required fuel amount of the engine under the current operating condition through the built-in algorithm, and sends corresponding control signal to the fuel pump 12 to adjust the output flow of the fuel pump 12.
