a car fuel tank

Abstract

The invention belongs to the technical field of fuel tanks, and specifically relates to a fuel tank for automobiles, including a fuel tank shell, a damage prevention mechanism, an oil inlet pipe, an anti-vibration mechanism, a protection mechanism and an anti-collision mechanism. The damage prevention mechanism is arranged inside the fuel tank shell, The anti-damage mechanism includes an inner tank, an installation gap, rubber balls and deoxygenated water. The inner tank is installed in the fuel tank shell, and the outer wall of the inner tank is fixedly fitted with several evenly distributed rubber balls, and each rubber ball The balls are fixedly fitted with the inner wall of the fuel tank shell, there is an installation gap between the inner tank and the fuel tank shell, and the installation gap is filled with a sufficient amount of deoxygenated water, and the oil inlet pipe is installed on the top of the fuel tank shell surface, and a dust blocking mechanism is installed in the oil inlet pipe to prevent dust from entering the inner tank. The automobile oil tank provided by the invention has the advantages of dust prevention and shock absorption.

Description

technical field [0001] The invention belongs to the technical field of fuel tanks, in particular to an automobile fuel tank. Background technique [0002] Automotive fuel tanks are divided into materials; iron fuel tanks and aluminum alloy fuel tanks. With the application and development of various new materials, the rust prevention of iron fuel tanks has become the biggest problem in the quality of fuel tanks. Especially in today's environment-friendly work. In terms of heavy trucks: During the promotion of National 45 vehicles, the problem that affects the promotion of new models is the quality of Chinese oil, among which the quality of the fuel tank that holds the fuel has become the key point. The aluminum alloy fuel tank not only can meet the strength direction but also has great advantages in corrosion resistance than iron and other new materials. It has also become the first choice for large buses and heavy trucks that consume a lot of fuel and require high fuel qua...

AI Technical Summary

Problems solved by technology

[0003] When the fuel tank on a large heavy truck is refueled, the dust raised by the fuel tank when the pipe cover is opened or closed is easy to enter the fuel tank, resulting in the formation of dirt in the fuel tank that is difficult to remove, which will affect the formation after a long time Precipitation, etc. make the quality of the oil poor, which affects the running condition of the engine and causes damage to the engine. At the same time, after a car accident, the damage of the fuel tank may cause secondary damage
