What Causes the Buzzing Sound and Resonance Sensation When Braking a Car?

The reasons for resonance sensation and noise when braking a car are as follows: 1. Tensioner pulley wear: The tensioner pulley's function is to keep the engine belt tight, preventing the generator and power steering pump from slipping. Due to prolonged pressure and high-speed rotation, the bearings inside the tensioner pulley are prone to wear, resulting in noise and resonance. When it's confirmed that the tensioner pulley is causing the buzzing sound and resonance, it's also necessary to check the engine mounts, as their role is to reduce vibrations and noise generated by the engine. 2. Exhaust pipe deformation: In most front-engine vehicles, the exhaust pipe extends from the bottom of the car to the rear. Driving on rough roads or impacts to the undercarriage can easily cause the exhaust pipe to dent or deform. A deformed exhaust pipe increases exhaust resistance, leading to buzzing sounds and resonance sensations from the exhaust system.

Are 5-seater SUVs eligible for 6-year exemption from inspection?

Private 5-seater vehicles are exempt from inspection within 6 years, but this does not mean that the inspection compliance mark does not need to be applied for within 6 years. Instead, they are exempt from online inspection within 6 years, but the motor vehicle inspection compliance mark must be applied for every 2 years. Below is more relevant information: Notes: 1. For the biennial regular inspection, the vehicle owner can directly apply to the traffic management department of the public security authority for the inspection mark after providing proof of compulsory liability insurance for traffic accidents and proof of payment or exemption from vehicle and vessel tax, without the need to undergo safety technical inspection at an inspection institution. 2. Before applying, the vehicle owner must resolve all traffic safety violations and accidents related to the vehicle. However, if the vehicle has been involved in an accident resulting in casualties, it must still be inspected according to the original inspection cycle. For vehicles registered for more than 6 years (including 6 years), they must still be inspected once a year as required; for those over 15 years (including 15 years), they must be inspected twice a year as required. The traffic management departments of public security authorities should set up windows for issuing inspection marks at municipal and county-level vehicle management offices, traffic management service stations, and traffic violation handling windows to facilitate the public in obtaining inspection marks quickly and conveniently.

Can 5000-grit sandpaper be used for car paint polishing?

5000-grit sandpaper can be used for polishing car paint. Generally, sandpaper comes in specifications such as 80, 120, 180, 240, 320, 400, 600, 1000, and 2000 grit. The higher the grit number, the finer the polishing effect, resulting in a smoother surface. Since 5000 grit is among the higher specifications of sandpaper, its polishing effect on car paint is undoubtedly trustworthy. Below is more relevant information: Precautions: 1. The polishing effect of 5000-grit sandpaper is not solely determined by the sandpaper itself; it is also greatly influenced by the polishing technique and method. If the technique or method is incorrect, it may not only fail to achieve the desired polishing effect but could also cause damage to the car paint. It is recommended to use toothpaste or polishing compound during the polishing process for better results. 2. Always pay attention to the polishing surface, controlling the pressure and duration of polishing. If you notice large areas of whitening on the car paint, stop immediately to avoid further damage. 3. Polishing car paint should not rely solely on sandpaper. It is advisable to use a specialized mechanical polisher for further treatment to achieve a better finish. Additionally, polished car paint becomes thinner, so applying a layer of paint over the polished surface is recommended. You can also wax the car's surface for added shine and protection.

Does the New Audi Still Burn Engine Oil?

New Audi still burns engine oil. Here are the specific details about the new Audi burning engine oil: New Audi burning engine oil: The previous generations of Audi did have quite severe engine oil burning issues, which affected many car owners to the extent that they had to keep a bottle of engine oil in the trunk for frequent top-ups. However, the third-generation EA888 engine has significantly alleviated the oil burning problem, and it basically does not affect usage anymore. Preventive measures for oil burning: Engine oil tends to corrode and age when exposed to high temperatures for prolonged periods, leading to thinning of the oil film and making it easier to enter the combustion chamber and participate in combustion. Therefore, using high-quality engine oil can greatly delay this phenomenon. Extended data: Poor cylinder sealing is the main cause of oil burning: Poor cylinder sealing is mainly due to excessive clearance between the piston and cylinder wall, improper installation of piston rings, or poor sealing performance, which allows oil on the cylinder wall to enter the combustion chamber, causing fuel combustion.
