When the central processor assembly 4 judges that the environmental temperature detected by the environmental temperature detection part 11 is lower than the allowable temperature of the high-grade fuel oil and higher than the first-level cold temperature value, which indicates that the vehicle is in a common cold area, the central processor assembly automatically controls the first flow valve 2111 to be opened at the moment, and then the high-grade fuel oil in the high-grade oil tank 101 is heated by using the high-temperature coolant discharged by the engine 200. Meanwhile, the central processing unit assembly 4 controls the electric oil suction pipe heater 3 to suck low-grade fuel oil, and the engine 200 burns the low-grade fuel oil. When the central processor assembly 4 judges that the detection data of the oil suction temperature detection piece 13 of the oil tank is greater than the allowable temperature of the high grade fuel oil and simultaneously judges that the detection data of the starting water temperature detection piece 12 is greater than the preset water temperature value, the central processor assembly 4 automatically controls the electric oil suction pipe heater 3 to be switched to suck the high grade fuel oil.

Then after a preset time (meanwhile, the detection data of the oil suction temperature detection part 13 of the oil tank is judged to be larger than the allowable temperature of the high-grade fuel oil, and the detection data of the engine water temperature detection part 12 is judged to be larger than the preset water temperature value), the central processor assembly 4 automatically controls the electric oil suction pipe heater 3 to be switched to suck the high-grade fuel oil again, continuously judges whether the detection data of the oil outlet temperature detection part 15 of the oil tank reaches the allowable temperature of the high-grade fuel oil within a certain time, and if the detection data reaches the allowable temperature of the high-grade fuel oil, the central processor assembly 4 controls the electric oil suction pipe heater 3 to continuously convey the high-grade fuel oil to the engine 200; otherwise, the above steps are repeated, the central processor assembly 4 controls the electric oil suction pipe heater 3 to switch to suction of the low-grade fuel oil again until the detection data of the oil tank oil outlet temperature detection piece 15 reaches the allowable temperature of the high-grade fuel oil within a certain time, and the engine 200 continuously burns the high-grade fuel oil.
When the central processor assembly 4 judges that the environmental temperature measured by the environmental temperature detection part 11 is lower than a first-level cold temperature value, it indicates that the vehicle is in an extremely cold area, at the moment, the central processor assembly automatically controls the first flow valve 2111 and the second flow valve 2211 to be opened simultaneously, so that high-temperature cooling liquid discharged by the engine 200 is used for carrying out multi-level heating on high-grade fuel oil in the high-grade fuel tank 101 and fuel oil in the fuel oil filter 300, the temperature reduction of the high-grade fuel oil in the conveying process is avoided, and the high-grade fuel oil conveyed to the engine 200 is ensured to reach the allowable temperature.

When the central processor assembly 4 judges that the detection data of the oil suction temperature detection piece 13 of the oil tank is greater than the allowable temperature of the high grade fuel oil and simultaneously judges that the detection data of the starting water temperature detection piece 12 is greater than the preset water temperature value, the central processor assembly 4 automatically controls the electric oil suction pipe heater 3 to be switched to suck the high grade fuel oil. Then the central processor assembly 4 continuously monitors the detection data of the oil outlet temperature detection piece 15 of the oil tank and the oil outlet temperature detection piece 302 of the filter, and when the detection data of the oil outlet temperature detection piece 15 of the oil tank and the oil outlet temperature detection piece 302 of the filter cannot reach the allowable temperature of the high-grade fuel within a certain time, the central processor assembly 4 automatically controls the electric oil suction pipe heater 3 to be switched to absorb the low-grade fuel again.

It should be noted that, when the central processing unit assembly 4 controls the electric oil suction pipe heater 3 to be switched to suck the high grade fuel oil, the central processing unit assembly 4 also needs to control the electric oil suction pipe heater 3 to delay for a certain time and then switch to be communicated with the return oil of the high grade oil tank 101, so as to ensure that the low grade fuel oil returned by the engine 200 returns to the low grade oil tank 102 as far as possible, and further improve the oil mixing phenomenon. When the central processor assembly 4 controls the electric oil suction pipe heater 3 to be switched to suck the low-grade fuel oil, the control principle is the same as the above, so that the high-grade fuel oil returned by the engine 200 is ensured to return to the high-grade fuel oil tank 101 as far as possible.
