Why does the Baojun 510 make a metallic sound after parking?

[DanielAnn]

The reason why the Baojun 510 makes a metallic sound after parking is the contraction noise of the exhaust pipe metal as the temperature gradually decreases. Common issues with the exhaust pipe: Common issues include water drainage and smoke emission. Specifically, water dripping from the car's exhaust pipe is a good sign, indicating that the vehicle's engine is burning fuel efficiently. When gasoline burns completely, it produces carbon dioxide and water. At high temperatures, water turns into steam, which is colorless and transparent. When the temperature drops below 100°C, the steam condenses back into water. Maintenance of the exhaust pipe: During cold starts in winter, close the choke to start the engine. After the engine warms up, make sure to open the choke promptly. Avoid driving at high speeds for extended periods with the choke closed. If the muffler surface is stained with oil, it may discolor or turn yellow after the engine heats up. If the muffler surface is covered with a large amount of dirt or mud, clean it promptly to prevent affecting its heat dissipation.
