What is the reason for the abnormal noise in the Geely Xingrui fuel tank?
2 Answers
Geely Xingrui fuel tank abnormal noise is caused by the irregular shape design of the fuel tank and the lack of an anti-splash plate design. The functions of engine oil are as follows: 1. Lubrication: When the engine is running, the friction between components is rapid and intense. A sufficiently thick oil film is needed between the piston and the cylinder to separate the two components and reduce friction. 2. Cooling: The engine generates a large amount of heat during operation, and the engine oil carries some of the heat back to the oil pan to dissipate. 3. Cleaning: Oil sludge, carbon deposits, metal wear particles, and inhaled dust can form on engine parts, which can easily lead to carbon buildup.
Recently, I've encountered many Xingrui owners discussing fuel tank noise issues. Quite a few people report hearing a thumping sound when going over speed bumps with half a tank of fuel. This is mainly related to the internal design of the fuel tank. Some vehicle fuel tanks come with built-in baffles to reduce fuel sloshing. If these baffles are poorly welded or become detached, the fuel can hit the metal plates during sloshing, creating noticeable noise. Additionally, the fuel tank's mounting position plays a role – chassis vibrations transmitted to the tank can amplify this sound. I recommend first checking at the dealership whether the fuel tank mounting bracket bolts are loose. If the noise persists after tightening, it's likely an internal tank issue requiring removal to inspect the baffles. As a last resort, replacing the entire fuel tank assembly may be necessary, as manufacturers now have solutions for such problems.
