Problems solved by technology

[0003] Existing heavy transport machinery and large vehicles generally use diesel as fuel, but diesel is affected by the temperature environment, and the cost of diesel with a lower freezing point is higher
Low-cost high-condensation-point diesel oil will hang wax or solidify in a low-temperature environment, which will affect the fuel supply of automobiles
At present, electric heating or water heating is generally used to heat the fuel in the fuel tank. However, electric heating consumes a lot of energy, and the electric power of the car battery is limited. Frequent use will affect the life of the car battery; once water heating leaks, it will damage the heat dissipation of the engine. and cause serious damage to the engine

Embodiment 1

[0055] Such as Figure 1-10 As shown, Embodiment 1 of the present application discloses a double fuel tank assembly, which includes: a fuel tank housing, the fuel tank housing encloses a cavity, and the fuel tank housing includes the upper upper housing 11 area, the middle middle housing 31 area and the lower shell 51 area of ​​the lower part; the middle grid rib structure is set in the cavity corresponding to the height area of ​​the middle shell 31, and the middle grid rib structure divides the middle part of the cavity into several middle grid cavities, and the middle grid cavity There is no connection between them in the radial direction, and the middle grid rib structure includes the first middle grid cavity group 33 and the second middle grid cavity group 34 which are not connected to each other, and the bottom end of the first middle grid cavity group 33 is provided with a first The oil ports communicate with each other to form the first fuel chamber, and the bottom end...

Embodiment 2

[0087] Such as Figure 1-10 As shown, Embodiment 2 of the present application provides an integrated double fuel tank and urea tank assembly, which includes the double fuel tank assembly and urea chamber in Embodiment 1; the urea chamber is located in the cavity surrounded by the fuel tank shell. By setting the urea chamber in the cavity surrounded by the fuel tank shell, the integrated arrangement of the fuel chamber and the urea chamber is realized, which reduces the volume of the integrated fuel tank, reduces the combined weight of the two, and makes the vehicle lighter; in addition, By integrating the fuel oil chamber and the urea chamber, the urea liquid in the urea chamber is heated by the oil return temperature of the first fuel oil chamber and / or the second fuel chamber to prevent the crystallization of the urea liquid in a low-temperature environment and realize the reuse of heat. Simplify your vehicle's thermal management system.

[0088] As an embodiment, at least ...

Embodiment 3

[0107] The integrated double fuel tank and urea tank assembly 1# and 2# are respectively processed by injection molding and rotomolding, the urea chamber volume, the first fuel chamber volume, and the second fuel oil chamber volume of the assembly 1# and 2# The cavity volume, volume and weight of the double fuel tank assembly are shown in Table 1:

[0108] Table 1

[0109]

[0110] It can be seen from Table 1 that the total volume of each cavity of the integrated double fuel tank and urea tank assembly processed by injection molding method is larger, which can increase the storage volume of fuel and urea solution, and is lighter in weight, which is beneficial to Lightweight vehicles.

Abstract

The invention discloses double oil tanks and an integrated double oil tank and urea tank assembly, and belongs to the field of automobile parts. The double-oil-tank assembly comprises an oil tank shell, the oil tank shell defines a cavity, and the oil tank shell comprises an upper shell area on the upper portion, a middle shell area in the middle and a lower shell area on the lower portion; a middle grid rib structure is arranged in an area, corresponding to the height of the middle shell, in the cavity, the middle part of the cavity is divided into a plurality of middle grid cavities by the middle grid rib structure, the middle grid cavities are not communicated in the radial direction, the middle grid rib structure comprises a first middle grid cavity group and a second middle grid cavity group which are not communicated with each other, the bottom end of the first middle grid cavity group is provided with a first oil passing opening so as to be communicated with each other to form a first fuel oil cavity, the bottom end of the second middle grid cavity group is provided with a second oil passing opening so as to be communicated with each other to form a second fuel oil cavity, and the first fuel oil cavity and the second fuel oil cavity are connected through a conversion valve.

Description

technical field [0001] The application relates to a double fuel tank, integrated double fuel tank and urea tank assembly, which belongs to the field of auto parts. Background technique [0002] With the rapid development of the automobile industry and the improvement of automobile environmental protection requirements, the fuel tank is an important safety and regulatory part in automobile parts, and its structure optimization and performance improvement have become a problem that major automobile manufacturers are competing to discuss and solve. [0003] Existing heavy transport machinery and large vehicles generally use diesel as fuel, but diesel is affected by the temperature environment, and diesel with a lower freezing point costs more. Low-cost high-condensation-point diesel oil will hang wax or solidify in a low-temperature environment, which will affect the fuel supply of automobiles. At present, electric heating or water heating is generally used to heat the fuel in...
