Description

Technical Field

[0002] In traditional fuel tank systems, the tank is usually only used to store fuel, and an external fuel pump and filter are required to ensure the purity and stability of the fuel during the process of transferring the fuel from the tank to the engine. This setting makes the fuel supply system more complex in structure, occupies a large space, and is cumbersome to maintain and install. The filters and fuel pumps that need to be installed separately on the engine inlet and outlet pipelines not only increase the cost, but also increase the potential failure points of the system. At the same time, more storage and turnover space is required, which affects the design and cost efficiency of the entire vehicle or machine.
