AI Technical Summary
Existing fuel refueling methods cannot meet the requirements for long-term storage without maintenance for more than 10 years, resulting in fuel oxidation and deterioration and unstable fuel supply.
A long-term maintenance-free fuel filling device and method is adopted, comprising a nitrogen cylinder, a fuel tank, and a switch valve. Through dehydration and deoxygenation treatment, nitrogen purging of pipelines, nitrogen replacement of fuel tank, and multiple fillings, the device ensures that there is no dissolved oxygen and water vapor in the fuel tank, thus achieving long-term storage and reliable fuel supply.
It enables fuel to be stored in a sealed state for more than 10 years, avoiding maintenance, ensuring reliable fuel supply to the engine, and reducing the risk of oxidation and deterioration.
