How to Deal with Scratches on the Car Light Glass Cover?

Scratches on the car light glass cover can be polished using scratch wax. Here are the specific details about car polishing: 1. Definition: Car polishing is a process in car detailing where the vehicle is polished before waxing, sealing, or coating. 2. Precautions: Before using sandpaper on the car, wash the entire vehicle with a strong paint cleaner to remove dirt. Avoid particles and dust that may cause new scratches during the polishing process. For paint surfaces with defects like coarse particles, fine sandpaper marks, or flow marks, gently sand them flat using 600~1000 grit wet sandpaper wrapped around a small rubber block before polishing.

Latest Preferential Policies for Automobiles in 2020

2020's latest preferential policies for automobiles are as follows: 1. Implementation of 'Two Cancellations and One Permission' for vehicles: cancellation of the requirement to paste the annual inspection label on the car window; cancellation of the requirement to spray characters on the body of private cars with 7 seats or more; permission for online appointment of vehicle annual inspections. 2. Nationwide mandatory implementation of the China VI-A standard for light vehicles: Starting from July 1st, vehicles must meet the China VI-A standard, including used cars. 3. Implementation of a point-adding system for driver's licenses: (1) Reporting others' traffic violations can earn certain additional points; (2) Answering questions correctly can add points—answering 9 out of 10 questions correctly adds 1 point, with a daily cap of 1 point and a total cap of 6 points. These additional points cannot be accumulated onto the driver's license score but can be used to offset penalty points for violations; (3) If a vehicle owner has no violations within a scoring cycle, they can receive 3 points, which can be accumulated for up to 4 years. 4. Mandatory installation of tire pressure monitoring systems: All new vehicles produced in 2020 must be equipped with tire pressure monitoring systems. 5. Supporting the implementation of the China VI standard: Accelerating the phasing out of old vehicles and further reducing or eliminating subsidies for scrapping old vehicles. Currently, most cities have adopted reduced subsidies, while some cities like Jinan and Hangzhou have completely eliminated scrapping subsidies for old vehicles. This policy particularly impacts commercial vehicles and trucks. 6. Reclassification of vehicle categories: Motorcycles are now classified as Class 1 passenger vehicles, meaning they can use highways from now on, but their speed must be maintained between 60-80 km/h. Two-wheeled motorcycles are not allowed to carry passengers and must drive in the far-right lane.

What Causes a Car to Lose Power and Fail to Accelerate When Going Uphill?

The reasons for a car losing power and failing to accelerate when going uphill are as follows: 1. Engine fuel system malfunction: The engine fuel system is a common problem area in cars. Clogged fuel injectors, leaking fuel lines, reduced fuel pump power, or a blocked fuel filter can all cause a car to lose power when going uphill. The feeling of powerlessness mainly occurs because the engine doesn't get enough fuel during uphill driving, leading to decreased combustion efficiency and insufficient horsepower. 2. Air intake system malfunction: The same applies to the air intake system. Besides fuel, the engine also needs air. If components like the air filter or throttle become clogged or malfunction, resulting in insufficient air intake, the car may also lack power when climbing hills. 3. Spark plug malfunction: Spark plugs are another common source of problems. If a spark plug fails to ignite properly, it can lead to acceleration issues. 4. Engine malfunction: At least one cylinder in the car's engine is not operating properly or has shut down. Generally, in a four-cylinder engine, if one cylinder fails to fire, the engine can still run. However, as the number of cylinders increases, this symptom becomes harder to detect.

What are the causes of Tiida key system failure?

Tiida key system failure is caused by detecting low battery power in the key or insufficient power in the car battery. The basic components of a remote key consist of the following two points: 1. Transmitter: Composed of a transmission switch, transmission antenna, integrated circuit, etc., containing an identification code storage circuit and an amplitude modulation circuit, with a button-type lithium battery installed on the opposite side of the circuit. The transmission frequency uses radio waves, and the transmission switch button sends a signal once per press; 2. Receiver: After the transmitter sends the identification code using shortwave modulation, it is received by the car's shortwave antenna and enters the shortwave high-frequency amplification processor of the receiver's electronic control unit through a distributor for demodulation, where it is compared with the demodulator's identification code.

What does '4WD with three differential locks' mean?

4WD with three differential locks refers to a four-wheel-drive vehicle equipped with front axle, center, and rear axle differential locks. The front axle differential lock primarily ensures that all wheels receive equal power distribution, the center differential lock synchronizes the rotation speed of front and rear wheels when wheel slippage occurs, and the rear axle differential lock maintains identical rotation speeds between the rear wheels and front axle. Most 4WD urban SUVs come standard with a center differential lock. Below is an extended explanation: The necessity for differential locks: Every vehicle is equipped with a differential, whose primary function is to allow left/right or front/rear drive wheels to rotate at different speeds. Without a differential, front-wheel-drive vehicles would easily experience tailspin during cornering. To maintain consistent rotational speeds during curved driving, differential locks become essential.

Is driving at 80 km/h in L gear harmful to the car?

Driving at 80 km/h in L gear causes some wear and tear on the transmission, but the impact is generally minimal. Car designs typically account for a certain degree of aggressive driving. Using L gear when going downhill: When going downhill, shifting into L gear restricts the transmission to a lower gear (usually first gear). This allows the engine braking effect to help control speed, reducing the burden on the brakes, minimizing the risk of brake fade, and improving driving safety. For vehicles without an L gear, manual mode can be used for downhill driving if available. Using L gear when climbing steep slopes: When climbing steep slopes, selecting L gear restricts the vehicle to lower gears, preventing frequent gear shifts. This provides more power for hill climbing and also helps protect the transmission.
