Abstract

The invention provides a fuel tank which comprises a fuel tank body, an oiling port and a ventilation port. The oiling port is formed in the sidewall of the fuel tank body, the ventilation port is formed in the top of the fuel tank body, and the top of the fuel tank body is further provided with a multifunctional valve and a buffer layer which is used for reducing influences of external force. The fuel tank is a six-layer coextrusion plastic fuel tank made of polyethylene, nylon and binding agents. The fuel tank is molded at a time, integration is achieved, and therefore the production efficiency is improved. The infiltration capacity of the fuel tank is lower than 0.2g/24h, so the fuel tank is friendly to environment and capable of saving energy. The fuel tank is light in weight, large in shape freedom degree and capable of utilizing the effective space inside a car to the maximum degree, so the oil storage capacity of the fuel tank of the car is greatly improved; the fuel tank is high in safety and reliability and resistant to impact, corrosion and rusting, sparks will not be generated to cause explosion in the friction or collision process, the fuel tank can generate springback automatically and will not deform permanently, and the service life is long.

Description

technical field [0001] The invention relates to a fuel tank. Background technique [0002] The fuel tank of the car is the only place to store fuel in the car. It is an important functional and safety component on the car. It must be firm and sealed; the plastic fuel tank has the characteristics of safer, more corrosion-resistant and long service life, and can be suitable for cars Lightweight developments are required to meet new automotive fuel economy standards. The fuel system is one of the main sources of HC compounds in vehicle emissions. Studies have shown that 45% of the vehicle's HC compound emissions come from the fuel system and crankcase, so improving the anti-penetration performance of the fuel tank has become the most direct, effective and important way to meet vehicle exhaust emission standards. The above-mentioned problems should be solved in the design and production process of the fuel tank. Contents of the invention [0003] The purpose of the prese...
