[0002] The fuel tanks of new energy vehicles are different from those of traditional fuel vehicles, especially in terms of design and function. First of all, the fuel tanks in new energy vehicles are mainly divided into two types: normal pressure fuel tanks and high-pressure fuel tanks. The high-pressure fuel tank system is a system for storing and transporting high-pressure fuel in new energy vehicles, mainly composed of components such as high-pressure fuel tanks, fuel pumps, oil pipelines, and fuel injectors. Its function is to store high-pressure fuel and, when the engine is running, send the high-pressure fuel into the combustion chamber through the fuel pump to provide power.
