Why is the engine noise loud in the new Sportage?

[ElizaLee]

The loud engine noise in the new Sportage is caused by carbon deposits. It is necessary to clean the carbon deposits in the engine combustion chamber, fuel injectors, intake valves, and throttle body. Finally, pour a fuel system cleaner into the fuel tank to remove all carbon deposits in the fuel lines. Reasons for increased engine noise: Engine mount aging or loosening: Engine mounts are rubber blocks placed between the engine and the vehicle frame. Their purpose is to reduce vibration and provide cushioning during engine operation, as well as to secure the engine. Once these mounts age or become loose, the engine will vibrate, and the faster the speed, the louder the vibration noise. Inappropriate engine oil usage: If the viscosity of the engine oil does not match the engine, it can easily lead to carbon deposits, resulting in increased engine noise. Engine misfire: An engine misfire mainly refers to one or more cylinders not functioning properly. Common symptoms include: intermittent exhaust flow from the vehicle, severe shaking of the exhaust pipe, and a clear "popping" or thumping sound from the engine.
