A kind of automobile modular fuel tank system

technical field

The invention belongs to the technical field of automobile application and relates to an automobile modular fuel tank system.

Background technique

In motor vehicles, fuel is mostly used as kinetic energy. For ease of use, generally motor vehicles that use fuel as kinetic energy are equipped with fixed fuel tanks to store fuel, thereby providing energy for the motor vehicle. However, most of the current motor vehicles (such as automobiles) only have a fixed fuel tank or an auxiliary fuel tank, which is affected by the space layout of the car chassis and the overall platform, resulting in a limited storage capacity of the fuel tank and the inability to store more fuel. Especially when the fuel gauge breaks down, the driver cannot know the situation of fuel tank storage, if the fuel tank is insufficient and the car travels to a place far away from the gas station, the vehicle may not reach the destination due to lack of fuel. However, for existing gasoline vehicles or hybrid vehicles, when the fuel tank is arranged, due to the insufficient utilization of the fuel tank layout space, the tank capacity is small, resulting in the problem of reduced cruising range. It is urgent to find a new type of fuel tank to solve the existing problem. insufficient.
