Abstract: Using the heat generated by the engine when the car is running, a thermal cycle system is added between the engine, the fuel tank, and the water tank.

1. Use the heat generated by the engine when the car is running to add a thermal cycle system between the engine, fuel tank, and water tank.

2. Design the original single fuel tank into a combined fuel tank consisting of a main fuel tank and a secondary fuel tank.

3. Install a water heater at the bottom of the fuel tank, and use the heat generated by the engine to heat the main fuel tank.

4. The main oil tank oil pipeline and the auxiliary oil tank oil pipe are connected with the engine oil circuit through the oil circuit switching valve. The auxiliary fuel tank is used when the car is started. After driving for 5-8 kilometers, the switching valve is moved and the oil circuit is cut into the main fuel tank.

5. Add 0# oil to the main oil tank and -35# oil to the auxiliary oil tank.

6. The main oil tank oil circuit is parallel to the heater pipeline, and the oil circuit pipeline and the heating pipeline are jacketed with insulation pipes to prevent the oil circuit from freezing in the cold season.

7. The fuel mark display of the main fuel tank is connected to the dial in the cab, and the fuel mark display of the auxiliary fuel tank can be displayed through a glass tube outside the tank.

8. The thermal cycle system is controlled by a valve, and the heating valve can be closed for transportation in summer.
