Description

Technical Field

[0001] The utility model relates to a fuel tank with a heat preservation function. Background Art

[0002] A fuel tank is a container for storing liquids such as fuel or lubricating oil in an automobile or other mechanical equipment. For an automobile, the fuel tank is an important part of the vehicle fuel system. It is usually installed at the bottom or side of the vehicle and connected to the engine through a fuel pipe to ensure that the engine can continuously obtain the required fuel. The design and material selection of the fuel tank will vary according to various factors such as the type, use, fuel type, and safety requirements of the vehicle. For example, some high-performance sports cars or racing cars may use lightweight but strong alloy materials to manufacture the fuel tank to reduce the vehicle weight and improve performance; while some commercial vehicles or off-road vehicles may use thicker steel plates or composite materials to manufacture the fuel tank to enhance its durability and impact resistance.

[0003] The fuel tank will affect the fluidity and stability of the fuel in a low-temperature environment, resulting in difficult vehicle starting and poor fuel supply. Usually, heat preservation materials are used for heat preservation of the fuel tank. However, in an outdoor low-temperature environment, the vehicle standing for a long time will cause the heat preservation effect to fail, and it is impossible to quickly heat up the fuel tank to reach the optimal temperature range for fuel preservation. When long-term heat preservation of the fuel tank is carried out, heat loss will occur, increasing the economic cost, and it is not easy to achieve effective heat preservation of the fuel tank.
