What cleaning agent should be used to clean wheel hubs?

To clean wheel hubs, you can use toilet cleaner, all-purpose cleaner, or tire cleaning agent. Below are the relevant introductions about toilet cleaner, all-purpose cleaner, and tire cleaning agent: Toilet cleaner: Its main component is hydrochloric acid, which has a strong corrosive effect. Therefore, it needs to be diluted before use. The corrosiveness is very effective in removing stubborn stains, but it can also damage the paint protection layer of the wheel hub. Thus, the amount used should be controlled, and it should be rinsed thoroughly with clean water after use to avoid residue. The final cleaning effect is average—it can remove surface stains but may not completely eliminate deeper rust stains or other stubborn stains. All-purpose cleaner: All-purpose cleaner is also a common household cleaning agent. Although it goes by one name, there are many different formulations for different stains, and even different brands may have different formulas. However, one thing is certain: all-purpose cleaners are chemically synthesized reagents. Before purchasing, be sure to explain your intended use to the seller. If the all-purpose cleaner's formula is not suitable, it may have poor cleaning performance or even corrode the wheel hub. Wheel hub cleaner: The effect of wheel hub cleaner is similar to that of foam cleaner. After spraying, it reacts with the dirt on the wheel hub's surface, producing a large number of bubbles. As the bubbles form, the stains dissolve and flow out with the cleaner. Professional wheel hub cleaners have no pungent odor during use, and the cleaning effect is very noticeable—brake dust and rust stains can be removed. They also act quickly and are easy to use. For the maintenance and cleaning of wheel hubs, if the stains are minimal, you can start by using clean water and a sponge brush to clean and rinse. When there are stubborn stains on the wheel hub's surface, you can then opt for professional cleaning agents, such as wheel hub cleaners or iron removers. These cleaners can effectively remove stains, but they may still have some corrosive effect on the wheel hub's outer coating, so thorough rinsing is necessary after cleaning. Additionally, wheel hubs inherently have a layer of metal protective film, so special care should be taken not to use paint brighteners or other abrasive materials during cleaning.

Does driving over a pothole at 60 mph affect the car?

Driving over a pothole at 60 mph can affect the car, primarily impacting the tires. Impact on tires and rims: Hitting a pothole at high speed can easily cause bulges, deformation, or damage to the tires, and in severe cases, may even lead to tire blowouts or rim damage. Impact on brake bearings: The sudden impact from hitting a pothole at high speed may cause irreversible damage to the bearings inside the brakes, leading to loose wheels or regular abnormal noises during subsequent driving. Impact on the body and electrical system: Severe vibrations can also cause varying degrees of deformation to the car body, cracking or loosening of interior and exterior trims, and deformation of electronic circuit boards and connectors inside the car, resulting in open circuits, poor connections, or short circuits.

How to Solve the Problem of Black Smoke from Diesel Vehicles?

The solutions for black smoke from diesel vehicles are: 1. Check, clean, or replace the air filter; 2. Clean the fuel system or add fuel cleaner; 3. Visit a 4S shop to detect and confirm the root cause of the fault, then replace the damaged parts; 4. Inspect and replace the fuel injector; 5. Check the pressure of the fuel injection pump and repair or replace it. The reasons for black smoke from diesel vehicles are: 1. Clogged air filter; 2. Poor fuel quality and carbon deposits; 3. Insufficient compression force; 4. Poor performance of the fuel injector; 5. Poor performance of the fuel injection pump. Diesel engines are divided into: 1. Spark-ignition engines: Gasoline engines inject gasoline into the intake pipe, mix it with air to form a combustible mixture, which then enters the cylinder and is ignited by the spark plug to expand and perform work; 2. Compression-ignition engines: Diesel engines directly inject diesel into the engine cylinder through the fuel injection pump and nozzle, where it mixes uniformly with the compressed air in the cylinder and self-ignites under high temperature and pressure to push the piston and perform work.

What is the penalty for driving at 133 km/h on a highway with a 120 km/h speed limit?

Driving at 133 km/h on a highway with a 120 km/h speed limit will result in a penalty of 3 demerit points and a fine. Safe speed on highways: Scientific research has shown that the safest speed in China is between 110-115 km/h. On highways with a speed limit of 120 km/h, the theoretically safest speed range is between 90 km/h and 110 km/h. Driving within this speed range is considered the safest. Penalties for speeding by ordinary vehicles on highways: Exceeding the speed limit by less than 10% will not be penalized; exceeding the speed limit by 10% to less than 20% will result in 3 demerit points; exceeding the speed limit by 20% to less than 50% will result in 6 demerit points; exceeding the speed limit by 50% or more will result in 12 demerit points.

What are the new regulations for the cancellation of annual inspections for private cars in 2021?

In 2021, the regulations for annual vehicle inspections have been adjusted, expanding the scope of exempted inspections and optimizing the inspection cycle. Starting from November 20, 2020, non-operational small and micro passenger vehicles (excluding minivans) with 7-9 seats and within 6 years of age have been included in the exempted inspection range. For non-operational small and micro passenger vehicles (excluding minivans) over 6 years but under 10 years of age, the inspection cycle has been relaxed from once a year to once every two years. This means that private cars only need to undergo two on-site inspections within 10 years, specifically in the 6th and 8th years. The purpose of annual inspections: The goal of annual inspections is to check the quality of the vehicle and whether all aspects of the vehicle meet the relevant regulations for road use, primarily to ensure driving safety and also to provide a safeguard for the driver's safety. Notes for annual vehicle inspections: Vehicles should undergo annual inspections within three months before the expiration of the current inspection validity period. According to relevant laws, the owner of the vehicle must first handle any related traffic violations or accidents before proceeding with the legal process to apply for the annual vehicle inspection.
