Description

Technical Field

[0001] This utility model belongs to the field of automotive fuel reduction testing technology, and more specifically, relates to an automotive fuel reduction testing device. Background Technology

[0002] With the development of automobiles, car users have higher requirements for the accuracy of vehicle fuel level, and correspondingly, higher requirements are also put forward for the whole vehicle fuel reduction test during the research and development process. At present, when conducting the fuel reduction test of automobiles, the fuel pump relay is usually short-circuited to directly draw fuel from the fuel tank through the fuel supply line. In this way, the electric fuel pump always works at the theoretical maximum pressure and flow rate, and the accuracy, reliability and safety of the test results and the test process cannot be guaranteed. However, the existing technology has the following problems: (1) The fuel reduction test needs to record the liquid level information (fuel pump resistance, instrument display, etc.) corresponding to each liter of fuel. It is not easy to control the volume of fuel drawn when the fuel is drawn at a high flow rate, and the test results have a large error; (2) High flow rate is easy to cause fuel splashing, overflow and other phenomena, which pose a great safety hazard; (3) When the fuel level is low, high flow rate fuel drawing can easily cause air bubbles to appear in the fuel supply line in advance, affecting the accuracy of the test results.

[0003] There is a technology in the prior art called "car fuel tank" with publication (announcement) number "CN105291824A". This technology discloses a car fuel tank, wherein the car fuel tank includes a tank body (1) and an oil inlet pipe (2) and an oil outlet pipe (3) that are disposed through the tank body (1). The tank body (1) has a plurality of shock-absorbing plates with through holes (4) vertically arranged inside, and a plurality of protrusions are formed on the inner wall of the tank body (1). The outer surface of the tank body (1) is also provided with a plurality of threaded rings (5) along the circumferential direction. The above design incorporates multiple perforated damping plates inside the fuel tank, allowing the pressure of the fuel inside to be dispersed and reduced when the fuel sloshes. Multiple protrusions are also included to break up any slicks in the fuel tank, further reducing pressure. Additionally, multiple threaded rings are installed on the outer surface of the tank, significantly improving its pressure resistance. These design elements greatly enhance the fuel tank's performance and lifespan.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
