Is It Serious If the Car Is Scratched and the White Paint Is Exposed?

When a car is scratched and the white paint is exposed, it needs to be addressed promptly. Below is an introduction to car paint: 1. Introduction One: The car's body paint consists of four layers, from the inside out: the electrocoat layer, the primer layer, the base coat layer, and the clear coat layer. The primary function of the electrocoat layer is rust prevention. After the entire body is assembled, it is immersed in an electrocoating bath, forming an electrocoat layer on the surface. 2. Introduction Two: Above the electrocoat layer is the primer layer, which primarily serves to prevent rust and enhances adhesion to the next layer of paint. Above the primer layer is the base coat layer, which is responsible for the car's aesthetic appearance. The various colors we see on car bodies are primarily due to the base coat layer. 3. Introduction Three: The outermost layer is the clear coat, a transparent paint layer that enhances the gloss of the car's paint and protects the base coat. Most minor scratches typically remain on the clear coat, but these can often be removed through simple polishing.

What Causes Brake Noise When the Car is Cold?

Cold-start brake noise occurs due to the following reasons: 1. In principle, braking involves friction between two components that converts mechanical energy into thermal energy. During this process, intense friction generates severe vibrations. When the vibration frequency matches or approaches the natural frequency of the brake pads (or related components), resonance occurs, leading to abnormal noises or squealing. This is particularly noticeable when descending garage ramps. 2. Braking systems are typically divided into disc brakes and drum brakes, with disc brakes being more prone to these abnormal noises/squeals. 3. Drum brakes: Due to their larger size and heavier weight, their natural frequency is lower. Low-frequency resonance from outside the vehicle often fails to transmit sound into the cabin, making occurrences rare. 4. Disc brakes: Their smaller size, lighter weight, and higher natural frequency make them susceptible to high-frequency resonance, resulting in abnormal noises/squeals. Resonance can occur across various components—brake discs, brake pads, calipers, etc. The piercing squeals heard are usually emitted by the resonance of the brake discs.

What is the fuel consumption of the Changan CS75?

The MIIT comprehensive fuel consumption of the Changan CS75 is 6.5L/100km, while the actual fuel consumption is around 9L/100km. The MIIT comprehensive fuel consumption is data collected under ideal conditions, and due to various factors such as environment and driving habits, the actual fuel consumption tends to be higher than the MIIT figure. Additional information: 1. Definition of fuel consumption: Fuel consumption generally refers to constant-speed fuel consumption, which is the vehicle's fuel consumption per 100 kilometers obtained in constant-speed fuel consumption tests specified by national standards for certain types of vehicles. 2. Types of vehicles include: (1) M1 category, M2 category with a maximum design total mass not exceeding 3.5 tons, and N1 category compressed natural gas vehicles; M1 category and N1 category vehicles with a maximum design total mass not exceeding 3.5 tons, tested according to the method specified in GB/T-12545.1-2008 "Test methods for fuel consumption of passenger cars." (2) M2 category, M3 category, N2 category, and N3 category compressed natural gas vehicles with a maximum design total mass exceeding 3.5 tons; M2 category, M3 category, and N category vehicles with a maximum total mass greater than or equal to 2 tons, tested according to the method specified in GB/T-12545.2-2001 "Test methods for fuel consumption of commercial vehicles."

Does the Dash Cam Record When the Car is Parked?

If equipped with a parking monitoring feature, the dash cam can continue to operate after the vehicle is parked and turned off. However, the duration of operation will not be very long, as the dash cam's functionality depends on its own power supply. Once the vehicle is turned off, there is no power supply, so it can only operate for a short period. More details about dash cams are as follows: 1. Introduction One: Dash cams have two types of parking recording functions. One type records continuously as long as the car is running, also known as full-time recording. The other type relies on motion detection, meaning it only starts recording when the vehicle experiences movement. Dash cams with this feature cannot continue recording after the vehicle is turned off. 2. Introduction Two: Some dash cams come with their own batteries, but the battery life is limited. Some can only record for half an hour. Therefore, if the owner wants to record the vehicle around the clock, it is almost impossible unless the car is running 24/7. Without the vehicle running and no power supply, relying solely on the dash cam's built-in battery makes continuous recording difficult.

What does PEPS mean in cars?

PEPS in cars refers to the keyless system, also known as the Passive Entry Passive Start system. The function of the keyless system is simply that when the driver steps into a designated range, the system can recognize the authorized driver and automatically open the door; when leaving the vehicle, the door locks will automatically lock and enter an anti-theft state. The working principle of the keyless system is as follows: 1. Carry the car key to the vicinity of the vehicle (the car key must have power), when pressing the vehicle button or pulling the door handle, the vehicle will receive the ignition or unlock signal and send a signal to the low-frequency antenna. 2. After receiving the signal, the low-frequency antenna will send a low-frequency trigger signal to the car key. 3. The car key receives the low-frequency trigger signal and sends a high-frequency unlock signal. 4. The high-frequency receiver receives the high-frequency unlock signal, and the entire vehicle completes the unlocking or ignition process.

Should You Engage the Handbrake or Shift Gears First When Driving?

For manual transmissions, you should shift into gear first before releasing the handbrake. This is to prevent the vehicle from rolling backward if parked on a slope—releasing the handbrake first could cause the car to roll, but shifting into gear first ensures it stays in place. For automatic transmissions, the order doesn't matter as much; you can either shift into gear or engage the handbrake first, as long as safety is ensured. Here’s an introduction to manual and automatic transmissions: 1. A manual transmission uses a manual gear-shifting mechanical transmission (also called a manual gearbox, MT) to adjust the vehicle's speed. This means the driver must manually move the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed changes. 2. An automatic transmission does not require the driver to shift gears manually. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions.
