To determine which national emission standard a vehicle complies with, you can follow these methods: 1. Check the vehicle's environmental protection label: The label usually has a clear marking indicating the standard. 2. Visit the public inquiry platform of the Motor Vehicle Environmental Protection Website: Enter the vehicle's VIN (Vehicle Identification Number) and the last 6 digits of the engine number to check the vehicle information. 3. Based on the vehicle's manufacturing year: Most vehicles manufactured after 2008 are compliant with National IV standard; vehicles registered in 2007 may be either National III or National IV; vehicles manufactured before 2007 are mostly below National IV, meaning National III or National II; vehicles manufactured before 2005 are mostly National II. 4. Take the vehicle registration certificate (original or copy) to the local vehicle management office for inquiry.

I most commonly use the motor vehicle registration certificate to check the emission standard. It's listed in the 'Emission Standard' column on the vehicle information page, showing standards like China IV or China V. If you don't have the certificate, the 'Registration' section on the back page of the driving license also records it. The environmental label is affixed to the top left corner of the windshield, displaying the emission standard in white text on a blue background. Last year, when I helped a friend check the emission standard of a used car, I simply had him search for 'Motor Vehicle Environmental Protection Website' on WeChat, enter the VIN and engine number, and the result appeared immediately. Some cities also restrict high-emission vehicles from entering urban areas, such as Beijing where China III diesel vehicles are banned within the Sixth Ring Road. Checking this in advance can help avoid fines.

Will Car Wax Be Washed Away by Rain?

No. Here is the relevant introduction: The wax itself is waterproof and can protect the car paint. The purpose of waxing is to make the car less susceptible to erosion from external dust and acid rain, thereby providing a certain protective effect on the paint and surface, helping to maintain the gloss and smoothness of the paint, and minimizing external pollution and erosion. Generally, the wax will naturally evaporate under sunlight in 1 to 2 weeks. However, the foam or detergent sprayed during car washing can be very harmful to the wax, almost washing it off in one go. Frequent washing can also remove the gloss of the paint, so it is recommended to wash the car with clean water from top to bottom to avoid damaging the paint.

Why is there no sound when playing music via Bluetooth in the Magotan?

Possible reasons for no sound when playing music via Bluetooth in the Magotan include: 1. Not enabled: The volume on the car navigation system or mobile phone is not turned on; simply enable it. 2. Incompatible pairing code: Some phones (e.g., iPhone) have music playback programming that is incompatible with certain car models, so only phone calls can be made, not music playback. The Bluetooth playback frequency band needs to be changed. 3. Multimedia music: The multimedia music function of the car Bluetooth is not enabled; it needs to be set up and turned on. 4. Signal interference: The media audio on the phone is not turned off, causing signal interference with the Bluetooth function.

What needs to be replaced for lifting the chassis?

There are several methods to lift the chassis: Replacing with larger tires (wheels): Owners who choose to modify by increasing tire size must be technically inclined. Even a simple lift of a few centimeters requires calculating various parameters, including wheel diameter, circumference, and rotation speed. Additionally, corresponding steel spacers need to be added to increase the space between the tires and the vehicle, and computer calibration is required to adjust the overall balance of the vehicle. Installing taller springs or modifying shock absorber height: Vehicles can have their chassis lifted by replacing the suspension springs. This is the simplest modification method. Choosing to modify the height of the shock absorbers can raise or lower the vehicle body.

What are the symptoms of a bad car fan relay?

Relay damage can cause the low-speed fan to stop working, leading to the engine coolant boiling over. Car Fan: The car fan is generally used to cool the radiator. The fan's operation drives air flow, which helps lower the water temperature. However, the water temperature should not be too low—engine temperature that is too low is also not ideal. Additionally, components like the thermostat and water pump work together, so cooling only begins when a certain temperature is reached. Car Air Conditioning: Generally includes a refrigeration unit, heating unit, and ventilation system. This integrated setup makes efficient use of the limited space inside the car, with a simple structure and easy operation, making it a popular modern car air conditioning system internationally.
