The invention provides a fuel tank and an automobile using the fuel tank, including a casing, an oil pump, a valve assembly and a limit assembly, the valve assembly includes a refueling valve, an oil quantity control valve and a safety valve, and the refueling valve is set in the casing at 40% of the rated volume Above the liquid level, the oil volume control valve includes an end cover, a welding layer and a valve body. The housing is provided with a bearing groove. The limit assembly includes a fixed plate and a limit plate. The outer wall is provided with a protruding column, the side of the fixed plate facing away from the housing is provided with an assembly column, the side of the assembly column facing the protruding column is provided with a limit column, and a barrier layer is provided inside the housing, and the thickness of the barrier layer is greater than or equal to 3% of the thickness of the shell, the present invention improves the sealing between the oil pump and the oil tank through the design of the limiting component, reduces the hydrocarbon emission caused by leakage, and squeezes the raised column through the limiting column. pressure, which improves the squeeze and limit function of the limit component to the oil pump, and prevents the leakage of the hydrocarbon mixture between the oil pump and the casing.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an oil tank and an automobile using the oil tank. Background technique [0002] With the rapid development of the automobile industry and the rapid popularization of automobiles, people's awareness and requirements for automobiles are also getting higher and higher. This requires automobile products with better driving control and better driving quality to meet people's growing travel needs. During the use of automobiles, the fuel tank is an important part of the automobile fuel system, and its structure and function are more and more stable and more and more people pay attention to. [0003] The existing oil tank has poor anti-penetration performance during use, and the leakage of hydrocarbons is relatively serious, which leads to a large amount of hydrocarbons seeping out of the fuel tank shell and being discharged into the atmosphere every day, making air pollution more s...
