How to Check the Fuel Tank?
1 Answers
For most family sedans, the fuel tank cap is located on the left or right rear side of the vehicle body. Structure of the automotive fuel tank: 1. Fuel Tank Cap: The fuel tank cap is typically designed with a claw-type mechanism and uses a corrugated leaf spring to press a rubber gasket against the perimeter of the fuel tank opening to ensure a tight seal. Some caps also feature a locking device to prevent detachment or loss. 2. Baffle Plate: The fuel tank usually contains baffle plates, which serve to separate the return fuel area from the pump's suction area. This increases the fuel circulation path, reduces the circulation speed, and aids in cooling, heat dissipation, bubble separation, and impurity sedimentation. 3. Fuel Gauge Sensor: (1) The fuel gauge sensor is a sliding rheostat installed inside the fuel tank and connected to the fuel level float. The float and rheostat form a small assembly, which is connected to the fuel gauge to indicate the amount of fuel in the tank. (2) The fuel supply and return lines act as the connection between the fuel tank and the engine, serving as the pathway for fuel delivery. 4. Fuel Filler Inlet: The fuel filler inlet screen filters out large impurities from the fuel. 5. Vent: Maintains equal pressure between the inside of the fuel tank and the external atmospheric pressure.
