In this embodiment, since the oil absorption of the engine 90 from the oil tank (the main oil tank 1 or the auxiliary oil tank 2) is directly related to the liquid level in the oil tank, if there is a difference in diesel oil level in the main oil tank 1 or the auxiliary oil tank 2, the oil tank with a high liquid level will absorb more diesel oil, whereas the oil tank with a low liquid level will absorb less diesel oil, so that the liquid levels in the main oil tank 1 and the auxiliary oil tank 2 will be kept dynamically level. After the vehicle is flamed out, if liquid level difference exists between the main oil tank 1 and the auxiliary oil tank 2, at the moment, the first oil outlet pipe 1a and the second oil outlet pipe 1b can generate siphon effect between the main oil tank 1 and the auxiliary oil tank 2, and diesel oil in the oil tank with high liquid level is sucked into the oil tank with low liquid level until the liquid levels in the main oil tank 1 and the auxiliary oil tank 2 are leveled.
The return oil of the engine 90 respectively returns to the main oil tank 1 and the auxiliary oil tank 2 after passing through the return tee joint 6. Since the return oil of the main oil tank 1 and the auxiliary oil tank 2 returns to the bottom of the oil tank and the pressure in the two oil tanks is consistent all the time, the return oil back pressure of the main oil tank 1 and the auxiliary oil tank 2 is only related to the liquid level height of the two oil tanks. When the liquid level of one oil tank is high, the pressure of the oil return port of the oil tank is higher than that of the other oil tank, so that the oil return amount of the oil tank with the high liquid level is smaller than that of the oil tank with the low liquid level until the liquid levels of the two oil tanks are leveled, and the oil return amounts are the same. Thereby realizing the simultaneous consumption of the fuel in the two fuel tanks.
