In this application embodiment, need not to fill low temperature matched oil in the main and auxiliary oil tank promptly, because the oil that matches with low temperature often price is high, and the operation cost is higher, consequently, this application embodiment has practiced thrift expensive price and operation cost.
The low-temperature matched oil products mainly refer to low-grade diesel oil, and in general, a plurality of diesel vehicles need to be filled with the low-grade diesel oil in winter to prevent oil products from being 'cured', and currently 7 grade diesel oil products in China are respectively 10#, 5#, 0#, -10#, -20#, -35# and-50 # diesel oil. For example, diesel fuel # 0 solidifies when the diesel fuel is below 0 ℃.
At present, the general schemes for solving the problem under the low-temperature environment generally have three kinds as follows: 1. the method is simple and feasible, but the use cost is greatly increased; 2. the combined fuel tank is 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 working of a vehicle, and 0# diesel oil is replaced after the vehicle is heated, so that the method is troublesome, difficult to maintain and high in use cost; 3. in addition, an electric heating mode is used for preheating the oil tank before starting, but the process is always about half an hour, and the capacity of the battery is required to be higher, and the battery cannot be used when the electric quantity of the battery is low, so that the stability and the feasibility are poor.
Therefore, in the embodiment of the application, when the vehicle has a power-on demand, and when the vehicle is in a cold region, that is, when the vehicle environment temperature is less than the first threshold value, and when the auxiliary fuel tank 6 temperature is less than the second threshold value, the lower temperature is indicated, the wax deposition of the fuel in the vehicle fuel tank may be caused.

When the engine 11 is started, the temperature of the coolant of the vehicle increases along with the operation of the engine 11, and when the engine is operated for a period of time, typically about 15 minutes, the coolant is related to the engine and the ambient temperature, and when the temperature of the coolant is higher than a fourth threshold, for example, when the temperature of the water of the diesel engine exceeds 80 degrees celsius, the thermostat is opened, the coolant on-off control part 3 is opened to heat the main tank 1, and the coolant serves the purpose of heating the main tank 1 through the coolant pipe 2 arranged below the main tank 1, as shown in fig. 2, the coolant pipe 2 may be circumferentially arranged at the bottom of the main tank 1 to heat the main tank 1.
In one possible implementation, the coolant line 2 is covered with insulating asbestos 12, so that heat losses can be avoided and the amount of electricity saved.
In one possible implementation, the coolant line 2 is isolated from the main tank 1 by the second heat conducting material 16, so that heat is prevented from being excessively concentrated at a certain point of the main tank 1, damage to the main tank 1 is prevented, and overheating is prevented.
In one possible implementation, the coolant on-off control part 3 includes a coolant on-off control valve to facilitate rapid on-off of the coolant pipe 2.
When the main oil tank 1 is heated by the cooling liquid for a period of time, and when the temperature of the main oil tank 1 is higher than the fifth threshold value, that is, when the oil in the main oil tank 1 and the oil in the auxiliary oil tank 6 are heated, the vehicle engine can perform normal driving circulation in a low-temperature environment, the cooling liquid on-off control part can be closed, the main auxiliary oil tank on-off control part is opened, the flow of oil between the main oil tank and the auxiliary oil tank is realized, the oil in the main oil tank 1 is timely supplemented into the auxiliary oil tank 6, and the engine 11 is timely supplied through the low-pressure oil pump 10.
