What is the current vehicle scrapping age limit?

China has issued new regulations on the scrapping of private cars, abolishing the mandatory scrapping age limit and replacing it with a guideline for scrapping when the mileage reaches 600,000 kilometers. The following are the regulations on vehicle usage standards under the new policy: 1. Annual inspection: Under the new policy, private cars need to undergo two annual inspections per year starting from the 15th year after registration. For vehicles over 20 years old, four regular inspections per year are required starting from the 21st year. If they fail to pass, they will be declared scrapped. 2. Power: The new policy has strict regulations on older vehicles during annual inspections. During power testing for private cars, the chassis output power must not be less than 60% of the engine's rated power or 65% of the maximum net power. 3. Mechanical inspection: Vehicles that fail safety or environmental standards during a mechanical inspection cycle will be forcibly scrapped. The power inspection project will also replace the existing fuel consumption project to phase out vehicles with poor performance indicators. 4. Mandatory scrapping: According to the "Mandatory Scrapping Standards for Motor Vehicles," vehicles that fail to obtain a passing inspection mark for three consecutive motor vehicle inspection cycles after the expiration of the inspection validity period shall be mandatorily scrapped.

How to Determine if Engine Oil Needs to Be Replaced?

Here are the methods to determine if engine oil needs to be replaced: 1. Smell Test: Open the hood, pull out the dipstick, and smell it closely. If there is a strong sour odor, it indicates the oil has deteriorated and needs immediate replacement. This method is the simplest and most convenient, but it cannot accurately determine the extent of deterioration. 2. Finger Rub Test: Use the dipstick to take a small amount of oil and rub it repeatedly between your thumb and forefinger. If the oil feels smooth, has good lubricity, minimal debris, and no friction, it means the oil quality is still good. If you feel impurities, poor viscosity, or even a gritty sensation, the oil is deteriorating and should be replaced promptly. 3. Color Test: Take a high-quality tissue paper, drip a few drops of used oil onto it, and observe after the oil has seeped through. Good oil will leave no powder, feel dry and smooth to the touch, and have a clear yellow infiltration zone. Deteriorated oil will appear dark brownish-black with impurities, indicating it should be replaced. 4. Light Test: Hold the dipstick at a 45-degree angle under light and observe the oil droplets. If you can clearly see no debris in the droplets, the oil is still good and can be replaced later. If there is a lot of debris in the droplets, the oil should be replaced.

How to Deal with Scratches on a White Car?

Scratches on a white car should be treated differently depending on the situation: 1. Minor scratches: If the scratches are not severe and have not damaged the deep layers of paint, toothpaste can be used to remove the marks. Apply toothpaste to these minor scratches and gently rub them away. The fine particles in the toothpaste help to gradually polish away the visible scratches. 2. Visible scratches without paint damage: A touch-up pen can be used. Touch-up pens are designed for small scratches, but it's important to choose the right color as some pens may have significant color differences from the car's paint. While touch-up pens are convenient, they have drawbacks, such as short adhesion time, potential peeling over time, and uneven application affecting aesthetics. 3. Scratches that have damaged the primer: Damage to the primer is more serious because the primer lies directly above the steel panel. Immediate action is needed to prevent rusting from rain. Use colored putty for repairs, sand the scratched area carefully without enlarging it, and ensure the area is clean. Apply the putty meticulously to fill the scratch completely, then finish with a compound and wax.

What is the principle of BYD's DMI technology?

BYD DM-I technology principle: The engine drives the generator to produce electricity, the generator charges the battery, and the motor drives the vehicle. The specific details of BYD DM-I technology are as follows: 1. This technology has one main motor and one auxiliary motor. The engine is only used for power generation by M1 and does not participate in driving the wheels. M2 is the main motor, which recovers energy during braking to charge the battery. 2. DM-I mainly relies on high-power and high-efficiency motors for driving. The main responsibility of the gasoline engine is to generate electricity in the high-efficiency speed range and directly drive the vehicle at appropriate times. By changing the traditional hybrid technology design that is mainly based on the engine, fuel consumption is significantly reduced.

What to Do If You Forget to Bring Your Driver's License on the Highway?

If you forget to bring your driver's license and encounter a traffic police officer, you can provide your name and ID number to the officer. The officer can then check with the headquarters or query the system to confirm whether you have a driver's license, as forgetting to bring your license does not constitute unlicensed driving. Below are some precautions to take while driving: 1. Follow traffic rules: When driving on the road, always adhere to traffic rules. Following traffic rules is not just about avoiding fines or penalties but also about ensuring the safety of yourself and others. Do not smoke, do not answer phone calls, yield to pedestrians, yield to non-motor vehicles, do not speed, and obey traffic signals. 2. Carry your driver's license and vehicle registration certificate: When driving on the road, always carry your driver's license and vehicle registration certificate. The vehicle registration certificate serves as the car's ID card, while the vehicle registration book is equivalent to the car's household registration document. The vehicle registration book does not need to be carried in the car.

How to Cool Down a Car After Exposure to Sunlight?

After a car has been exposed to sunlight, a specialized cooling spray can be used to reduce the temperature. Here are some related tips about cooling down a car after sun exposure: 1. Specialized Cooling Spray: The main components of the cooling spray are cooling agents and dry ice. Spraying the cooling agent on the car's surface or any interior accessories can instantly lower the temperature inside the car within minutes. 2. Install Heat Insulation Film: Applying an explosion-proof heat insulation film to the car can help insulate heat, block UV rays, prevent explosions, and reflect some of the heat, effectively reducing the amount of heat entering the car. This prevents the interior temperature from becoming too high in the summer, which could otherwise affect driving comfort.
