Fuel-tank of motor vehicle

Abstract

A motor vehicle fuel tank It belongs to the field of fuel tank, comprises a tank body and an oil suction pipe, A partition plate is arranged inside the tank body to divide the tank body into a crude oil tank and an oil suction tank, The filling port is located in the crude oil tank, As that space length of the oil suction tank is small than the space length of the crude oil tank, the suction pipeextends into the suction tank to suck fuel, As that oil is supply by extending the oil suction pipe into the oil suction tank with small space length, The risk that the original suction pipe can not suck oil due to the excessively long original tank body can be reduced, and since the liquid level change of the suction tank with the smaller space length is far smaller than that of the original tankwith the larger space length when the whole tank is inclined, the fuel supply can be ensured when the suction pipe can face the gradient of the shorter distance.

Description

technical field [0001] The invention relates to the field of fuel tanks, in particular to a motor vehicle fuel tank. Background technique [0002] The fuel tank plays an important role in storing fuel. For current motor vehicles, especially tractors with relatively small space at the bottom, in order to meet the capacity of the fuel tank at the same time, it is often made into a relatively long structure. like figure 1 As shown in the figure, when the vehicle is going uphill or downhill, since the oil suction pipe is often set in the middle of the fuel tank, the fuel tank will tilt forward or backward. Fuel fuel causes the engine to stall, and the motor vehicle stalls on the slope and loses power.

Problems solved by technology

[0002] The fuel tank plays an important role in storing fuel. For current motor vehicles, especially tractors with relatively small space at the bottom, in order to meet the capacity of the fuel tank at the same time, it is often made into a relatively long structure. like figure 1 As shown in the figure, when the vehicle is going uphill or downhill, since the oil suction pipe is often set in the middle of the fuel tank, the fuel tank will tilt forward or backward. The engine stalls due to fuel, and the motor vehicle loses power when it stalls on the slope, which can easily trap the motor vehicle on the slope, and even cause personal and property losses due to the inability to control the machine.

[0003] Although the upper groove can be set at the bottom of the fuel tank, the oil suction pipe can extend into the groove to temporarily reserve the fuel, which can play a certain emergency effect when going uphill or downhill, but on the one hand, the depth of the groove should not be too deep, Because the height of the bottom of the tractor from the ground is limited, on the other hand, the groove is too shallow, and the fuel tank can't store much fuel when tilted

[0004] Although the known published patent CN102616131B fuel tank with high volume utilization rate and CN101450612A vehicle fuel tank disclose the use of a kind of oil suction pipe structure that can slide to the corresponding lower corner along with the uphill and downhill, the length of the oil suction pipe is greater than that of the fuel tank. height, so the oil suction pipe is easy to coil in the fuel tank, causing the oil suction pipe to be easily knotted or bent to affect the oil absorption, and the fuel tank is often equipped with an oil return pipe and a liquid level sensor, which is easy to be compared with a long The oil suction pipe interferes, and even makes the oil suction pipe entangled on it, so its practical application value is very small, and it has not been promoted in the market at present
