And the controller is also used for opening the cooling liquid on-off control part 3 when the temperature of the cooling liquid is greater than a fourth threshold value so that the cooling liquid heats the main oil tank 1, and closing the cooling liquid on-off control part 3 and opening the main and auxiliary oil tank on-off control part 5 when the temperature of the main oil tank 1 is greater than a fifth threshold value.
In other words, in the embodiment of the application, the oil product matched at low temperature does not need to be filled into the main oil tank and the auxiliary oil tank, and the oil product matched at low temperature is expensive and high in operation cost, so that the embodiment of the application saves the expensive price and operation cost.
The low-temperature matched diesel mainly refers to low-grade diesel, generally, a plurality of diesel vehicles in winter need to be filled with the low-grade diesel to prevent the oil from being wax-precipitated, and the 7-grade diesel currently in China is respectively 10#, 5#, 0#, -10#, -20#, -35# and-50 # diesel. For example, 0# diesel oil can be solidified when the temperature of the diesel oil is lower than 0 ℃.
The conventional solutions for solving the low temperature environment generally include the following three solutions: 1. oil products matched at low temperature are filled, and the method is simple and easy to implement, but the use cost is greatly increased; 2. the combined fuel tanks are used, two mutually independent fuel tanks are integrated together and used for storing low-grade diesel oil and 0# diesel oil with different grades, fuel is provided for low-temperature starting and normal operation of a vehicle, and the 0# diesel oil is replaced after the vehicle is heated, so that the method is troublesome, difficult to maintain and increased in use cost; 3. the other is to use the mode of electrical heating, and the fuel feeding tank preheats before starting, but the process often lasts about half an hour, and has proposed higher requirement to the capacity of battery, and can't use when the battery power is low, and stability, feasibility are relatively poor.
Therefore, when the vehicle needs to be powered on, and when the vehicle is in a cold area, namely when the ambient temperature of the vehicle is lower than the first threshold value, and the temperature of the auxiliary oil tank 6 is lower than the second threshold value, the temperature is low, and wax deposition of oil in the vehicle oil tank may be caused.

In a possible implementation manner, the auxiliary oil tank electric heating part 7 comprises an electric heating resistance wire, the auxiliary oil tank 6 is heated by the electric heating resistance wire, the auxiliary oil tank can be rapidly heated, and the electric consumption of the storage battery 8 is low;

In a possible implementation mode, the auxiliary oil tank electric heating component 7 is isolated from the auxiliary oil tank 6 through the first heat conducting material 15, so that heat is prevented from being excessively concentrated on a certain point of the auxiliary oil tank 6, damage to the auxiliary oil tank 6 is avoided, and overheating is avoided.
In a possible implementation mode, the auxiliary fuel tank electric heating component comprises a resistance wire relay 9, and whether the electric heating resistance wire heats the auxiliary fuel tank 6 or not is controlled through a switch of the resistance wire relay 9.
In one possible implementation, the main-auxiliary fuel tank on-off control component 5 comprises a main-auxiliary fuel tank on-off control valve to facilitate and rapidly realize the on-off of the main-auxiliary fuel tank.
When the auxiliary oil tank 6 is heated by the auxiliary oil tank electric heating component 7 for a period of time, and when the temperature of the auxiliary oil tank 6 is greater than a third threshold value, the auxiliary oil tank electric heating component 7 can be controlled to stop heating the auxiliary oil tank 6, and the engine 11 can be controlled to start, that is, the oil in the auxiliary oil tank 6 is heated at the moment, so that the normal driving cycle of the vehicle engine can be performed, that is, the low-pressure oil pump 10 can be used for pumping the oil in the auxiliary oil tank 6 into the engine 11, so as to realize the operation of the engine 11.
When the engine 11 is started, the temperature of the coolant of the vehicle rises with the operation of the engine 11, when the engine operates for a period of time, generally about 15 minutes, which is related to the temperature of the engine and the environment, when the temperature of the coolant is greater than a fourth threshold value, for example, when the temperature of the water in the diesel engine exceeds 80 ℃, the thermostat is opened, and the coolant on-off control component 3 is opened, so that the coolant heats the main oil tank 1, and the coolant plays a role of heating the main oil tank 1 through the coolant pipeline 2 arranged below the main oil tank 1, as shown in fig. 2, the coolant pipeline 2 can be arranged around the bottom of the main oil tank 1, so as to heat the main oil tank 1.
In a possible implementation, the coolant line 2 is coated with heat-insulating asbestos 12, so that heat losses can be avoided and the electrical quantity is saved.
In a possible implementation manner, the coolant pipeline 2 is isolated from the main oil tank 1 through the second heat conduction material 16, so that heat is prevented from being excessively concentrated on a certain point of the main oil tank 1, damage to the main oil tank 1 is avoided, and overheating is avoided.
In one possible implementation, the coolant on-off control component 3 comprises a coolant on-off control valve to facilitate and rapidly switch on and off the coolant line 2.
After the main oil tank 1 is heated by the cooling liquid for a period of time, when the temperature of the main oil tank 1 is greater than a fifth threshold value, namely the oil in the main oil tank 1 and the oil in the auxiliary oil tank 6 are heated at the moment, the oil can be supplied to a vehicle engine to carry out normal driving circulation in a low-temperature environment, the on-off control component of the cooling liquid can be closed, the on-off control component of the main oil tank and the auxiliary oil tank is opened, the flow of the oil between the main oil tank and the auxiliary oil tank is realized, and the oil in the main oil tank 1 is timely supplemented into the auxiliary oil tank 6 so as to be timely supplied to the engine 11 through the low-pressure oil pump 10.
