Novel fuel tank for automobile

Abstract

The invention provides a novel fuel tank for an automobile. The fuel tank comprises a tank body, a fuel filler, a fuel return pipe, a fuel supply pipe, a fuel pump, a gasoline steam output pipe and a fuel level sensor, wherein the tank body comprises an inner layer and an outer layer, the fuel pump is mounted at the lower part in the tank body and connected with the fuel supply pipe, the fuel level sensor is mounted at the top in the tank body, the fuel return pipe is mounted on the left side of the fuel supply pipe, the gasoline steam output pipe is mounted on the left side of the fuel return pipe, a check valve is mounted in the gasoline steam output pipe, the fuel filler is mounted on the right side of the fuel supply pipe, a fuel tank cover is mounted at the top of the fuel filler, and the fuel filler is mounted at the top of the tank body. The fuel tank has the benefits as follows: a vacuum interlayer is arranged between the outer layer and the inner layer, has insulation and heat isolation functions, can prevent fuel from freezing and can play roles in preventing burning of the fuel tank and explosives due to fuel temperature rise; the fuel tank is simple in structure, convenient to use, higher in safety, convenient to mount and capable of reducing environmental pollution.

Description

technical field

[0001] The invention is a novel fuel tank for automobiles, which belongs to the field of mechanical equipment for automobile parts. Background technique

[0002] In the prior art, most cars use gasoline with good volatility. The volatility and flammability of gasoline cause the vehicle to easily cause fire after an accident, thereby causing secondary damage to members; in addition When a car using a traditional tank is refueling at a gas station, because the cavity of the fuel tank is filled with a high concentration of gasoline vapor, the gasoline vapor will immediately diffuse into the air after the fuel tank cap is opened, which not only poses a threat to the safety of the gas station threat, but also pollute the environment and cause a waste of resources. In order to solve this problem, a solution is needed to avoid the volatilization of gasoline in the fuel tank without affecting the use function, and the existing fuel tanks are mostly single-layer stru...
