What are the disadvantages of buying stock cars?

Buying stock cars has the following disadvantages: 1. Long-term parking of stock cars can lead to aging of batteries, tires, circuits, etc., posing safety hazards; 2. Components such as tires may become out-of-round due to prolonged fixed contact with the ground; 3. Sun exposure accelerates the premature aging of the vehicle's paint and rubber seals, rain may cause moisture damage to electronic components, dust can clog various heat dissipation devices and drainage holes, and high-density storage may even lead to body scratches; 4. Since stock cars are never washed, they are more susceptible to natural corrosion, leading to surface oxidation and rust in some areas.

Can National IV Vehicles Be Licensed?

National IV vehicles will begin to be completely phased out. If licensing is required, it is advisable to consult the local vehicle management office, as restrictions vary by province. According to national announcements, due to fuel upgrades, the National Fifth Stage Motor Vehicle Pollutant Emission Standards will be implemented in different regions and at different times, with the aim of reducing vehicle exhaust emissions. The update of emission standards is to better control environmental pollution by utilizing technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, to control and reduce vehicle pollutant emissions.

Why doesn't water come out when the car air conditioner is turned on?

Introduction to the reasons why no water comes out when the car air conditioner is turned on: 1. The air conditioner needs to turn on the compressor, that is, AC cooling, to produce condensed water. 2. The air humidity is not high enough. Condensed water comes from the water vapor in the air, which condenses into water droplets when it encounters cold. If the air humidity is low, the water will mostly adhere to the pipe walls, with very little flowing down, making it almost invisible. Below is an introduction to car air conditioner maintenance: 1. Do not adjust the air conditioner vent direction randomly: When using the air conditioner, not paying attention to adjusting the direction of the air flow is not conducive to achieving the best effect. According to the principle that cold air sinks and hot air rises, the correct approach is to point the vents upward when cooling and downward when heating. 2. The air conditioner should be started regularly in winter: In some regions where winters are relatively warm, some car owners do not use the air conditioner at all during the winter. Prolonged disuse can cause the rubber seals to age, and the lubricant on the internal components of the air conditioner to dry out. Starting the air conditioner regularly allows the components to be lubricated, maintaining good condition. Therefore, it is best to start the air conditioner once a week in winter. 3. The duration of each use of the air conditioner should not be too long: Some people turn on the air conditioner as soon as they get in the car and keep it running for a long time. Prolonged use can increase the pressure on the condenser, causing wear and tear to the cooling system. Therefore, the duration of each use of the air conditioner should not be too long. If the temperature inside the car has reached a comfortable level, the air conditioner can be turned off and restarted after a while. 4. In summer, ventilate and cool down before driving, then switch to internal circulation: In hot summers, many car owners are accustomed to turning on the internal circulation of the air conditioner as soon as they get in the car, thinking that this will cool the interior faster. However, since the temperature inside the car is higher than outside, this approach is not effective. Upon entering the car, you should first open the windows for ventilation and turn on the external circulation to expel the hot air. After the interior temperature drops, you can then switch to internal circulation.

Can National IV Second-hand Cars Be Transferred?

National IV second-hand cars can be transferred in regions outside the key air pollution prevention and control areas such as Beijing, Tianjin, Hebei, Shanghai, Jiangsu, Zhejiang, Guangzhou, Shenzhen, Zhuhai, Foshan, Jiangmen, Dongguan, and Zhongshan. Things to note when transferring a second-hand car: Check the seller's ID to verify if the seller has the right to use and dispose of the vehicle; The Vehicle Identification Number (VIN) on the dashboard should match the one registered on the vehicle license; Check the original purchase invoice of the vehicle, which serves as proof of the vehicle's origin; Check the vehicle registration certificate, as every vehicle on the road is registered with the local vehicle management office; Check the vehicle license, which is the legal proof of the vehicle's right to operate; Check the vehicle license plate for any signs of tampering or alteration, ensuring it matches the plate number registered on the vehicle license.

What are the differences between China 4 and China 5 standards?

The difference between China 4 and China 5 standards lies in the upper limit of sulfur content: the sulfur content limit for China 4 standard gasoline is 10mg, while for China 5 standard gasoline, it is 50mg. China 5 imposes stricter controls on nitrogen oxides compared to China 4, with China 5 setting the emission limit at 25%. The China 4 emission standard is the fourth stage of national motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include HC, NOx, CO, PM, etc. These are controlled through technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices.

What to Pay Attention to When Transferring Ownership of a Used Car?

When transferring ownership of a used car, pay attention to the following points: 1. Check if the vehicle's appearance has been modified, ensuring it matches the photo on the vehicle registration certificate, including but not limited to: added body kits, roof racks, side steps, snorkels, body decals, advertisements, body color, front and rear bumpers, headlights, tire size, spoilers, suspension, etc.; 2. Verify if the engine has been modified, such as adding a turbocharger or replacing the intake system; 3. Ensure the Vehicle Identification Number (VIN) and engine number are clear and can be imprinted; 4. Prepare all necessary transfer documents, such as the original IDs of both buyer and seller, vehicle registration certificate, vehicle title, transfer invoice, and in cities with license plate restrictions, an indicator certificate is also required; 5. Confirm the vehicle's annual inspection is valid and check for any outstanding traffic violations within the inspection period.
