What is the Difference Between Air Suspension and Conventional Suspension in Cars?

Conventional suspension typically consists of springs and shock absorbers, while air suspension replaces the springs with air springs. Here are the key differences: 1. Different Components: Conventional suspension in cars usually includes springs and shock absorbers. These are crucial components connecting the car body to the wheels, primarily aimed at improving ride comfort and handling stability. In contrast, air suspension replaces the springs with air springs and adds an electronic control system and an air pump. 2. Advantages of Air Suspension: When compressed, it contracts, and when released, it expands. Since the force is transmitted through air, it has a larger compression range, offering better comfort than conventional suspension. It also allows for adjusting the vehicle height—when driving at high speeds, the body lowers to its minimum height, reducing the center of gravity and enhancing stability.

Is the Original Car Paint Really That Important?

Original car paint is indeed important. The factory paint consists of a primer, middle coat, color coat, and clear coat. If the primer of the factory paint is scratched off, it is impossible to fully repair this original primer layer during repainting. Subsequent repainting only includes the middle coat, color coat, and clear coat layers. Electrophoretic layer: In the painting workshop of the car factory, the car body undergoes pre-spraying treatment to meet electrophoretic requirements, preventing metal rusting, commonly referred to as the primer. Middle coat: Applied on the electrophoretic layer, it provides adhesion conditions for the color coat, enhances the anti-corrosion protection of the car body, and is then dried in an environment above 130 degrees Celsius. Color coat: Applied under constant temperature and humidity conditions, controlled by a computer to spray different colors, it further strengthens the anti-corrosion protection of the car body. Clear coat: Sprayed automatically by a computer, it becomes the outermost transparent protective layer of the car. After all spraying is completed, it is dried in a drying oven at temperatures ranging from 130°C to 190°C to protect the car body color and prevent minor scratches.

Should You Use Cold or Warm Air to Defog the Windshield?

Both cold and warm air can be used to defog car windows, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the surface and achieving defogging. The method of using warm air is similar to cold air defogging, but it's important to note that warm air should not be used on rainy days as it can initially worsen the fogging. When the car windows fog up, it's best to use the external circulation mode. The reason for car window fogging: There is a temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the side with the lower temperature will have a lower saturated vapor pressure on its surface compared to the surrounding environment, causing water vapor to gather on the glass surface and form tiny droplets, resulting in fogging. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car and the air conditioning is not turned on promptly, the exhaled air has high humidity, quickly causing the windshield to fog up. In this case, turn on the air conditioning to blow cold air onto the windshield, utilizing the dehumidifying function to remove the fog quickly. If the humidity is too high and the air conditioning is ineffective, slightly open the windows to rapidly reduce the humidity inside the cabin. Combining this with the air conditioning can speed up the process. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, blowing warm air onto the glass quickly raises the temperature of the windshield, reducing the temperature difference between the inner and outer surfaces of the glass, thereby preventing heavy fogging. However, it's worth noting that the rear and side windows heat up more slowly, so it takes longer to completely remove the fog. Whether using automatic or manual air conditioning, turning it on helps with dehumidification. Avoid setting the temperature to the coldest position, as this can cause frost to form on the outer surface of the windshield over time. Applying Anti-Fog Spray or Other Preventive Measures: Spray a small amount of defogging agent onto the car windows and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film forms on the surface, effectively preventing water vapor from condensing and forming fog. This is especially useful in cold winters. Alternatives to anti-fog spray include dish soap, soapy water, glycerin, alcohol, or saline solution. After applying, let it dry and then wipe off any excess residue with a chamois or soft dry cloth. This can keep the windows fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not too heavy, opening the side windows can create airflow between the inside and outside of the car, reducing the temperature difference and gradually eliminating the fog. The principle of this method is the same as using cold air from the air conditioning. However, this method has obvious drawbacks and cannot be used during rain, snow, on highways, or when the fog is heavy. Rear Windshield Heating: Most cars are equipped with a rear windshield heating function. The button location may vary, but the function is the same. Turn on the windshield heating switch, and the fog on the rear windshield will disappear in about a minute.

Why can't you make a U-turn on white dashed lines?

Because making a U-turn on white dashed lines can easily lead to traffic accidents. White dashed lines are pedestrian crossings, which are signs for pedestrians to pass through. Here are the relevant explanations: 1. White dashed lines: When marked on road sections, white dashed lines are used to separate traffic flows in the same direction or serve as safety distance recognition lines for driving; when marked at intersections, they are used to guide vehicle movement. 2. Situations where U-turns are allowed: At locations with designated U-turn openings, drivers should turn on the left turn signal in advance and make a U-turn without affecting other normal traffic; at intersections with U-turn signals, ensure the U-turn signal is green and make the U-turn within the designated lane; at intersections with U-turn signs, make a U-turn based on actual conditions without obstructing other vehicles or pedestrians, and at intersections without explicit prohibitions against U-turns or left turns.

How much does it cost to apply for ETC?

Installing ETC is currently free of charge. To compete for customers, various banks now provide the equipment for free, which previously cost several hundred yuan. The electronic toll collection tag, which records vehicle information, is an onboard device that communicates with dedicated equipment installed in ETC lanes. The ETC card and electronic tag must be used together to achieve non-stop passage in ETC lanes. Below is how to apply for ETC: 1. Applying at a business office: You only need to bring the owner's ID card and vehicle license. If it is handled by an authorized agent, the agent's ID card is also required. 2. Applying online via mobile phone: Users only need to fill in personal and vehicle information on the corresponding interface and upload images such as ID card and vehicle license to complete the application.

Is the Left-Side Overtaking Always Fully at Fault?

Not necessarily. The traffic laws clearly state that overtaking from the right side is a violation and is strictly prohibited. Drivers who overtake from the right side will be penalized with 3 demerit points and a fine of 200 yuan. However, this does not mean that overtaking from the left side is entirely reasonable or legal. Here are six situations where overtaking from the left side will result in full liability for an accident: 1. Oncoming traffic: Overtaking when there is a possibility of encountering oncoming traffic, resulting in an accident, will hold the overtaking driver fully liable. 2. No right lane: Overtaking from the right side when there is no right lane available, resulting in an accident, will hold the overtaking driver fully liable. 3. Overtaking a vehicle that is already overtaking: Overtaking a vehicle that is in the process of overtaking another, resulting in an accident, will hold the overtaking driver fully liable. 4. Making a U-turn: Overtaking a vehicle that is in the process of making a U-turn, resulting in an accident, will hold the overtaking driver fully liable. 5. Turning left: Overtaking a vehicle that is in the process of turning left, resulting in an accident, will hold the overtaking driver fully liable. 6. Intersections, bridges, curves, steep slopes, or tunnels: Overtaking at intersections, bridges, curves, steep slopes, or tunnels, resulting in an accident, will hold the overtaking driver fully liable.
