Abstract

The invention discloses a vehicle fuel tank, which comprises a main fuel tank body, a secondary fuel tank body, a refuelling pipe, a connecting pipe, a the first air duct, a the second air duct and the first and the second control valves respectively controlled the make and break of the first and the second air ducts in accordance with the fuel level. The refuelling pipe is communicated to the fuel inlet of the secondary fuel tank body, and the connecting pipe is communicated to the fuel outlet of the secondary fuel tank body and the fuel inlet of the main fuel tank body. The first control valve is disposed on the top space of the main fuel tank body, which is connected to one end of the first air duct, and the other end of the air duct is communicated to the atmosphere. The second control valve disposed on the top space of the secondary fuel tank body is connected to one end of the second air duct, and the other end of the second air duct is communicated to the atmosphere. Through the arrangement of the main and secondary fuel tank bodies, the volume of the fuel tank can be effectively increased, and the requirement of the fuel capacity can be met as well.

Description

technical field [0001] The invention relates to an automobile oil tank used in an automobile oil supply system, in particular to an automobile oil tank used for storing fuel and supplying fuel to an engine system. Background technique [0002] Automobile fuel tank is an important part of automobile fuel supply system, and the fuel storage capacity of the fuel tank is also one of the indicators for testing driving performance. At present, most of the fuel tank structures of passenger cars use a single fuel tank structure, and the oil storage capacity of the fuel tank of this structure can generally meet the driving distance of more than 300 kilometers. [0003] During the design process of a car, when arranging a car fuel tank, it is often affected by the car body structure, chassis-related components and other auxiliary components, resulting in insufficient space to arrange a car fuel tank with sufficient volume. [0004] Due to the arrangement of the body structure and cha...
