To qualify, the applicant must have maintained an AA-level or higher automotive repair certification in the previous year. The application materials should be submitted online via the Public Service Platform for Motor Vehicle Maintenance. Upon approval, the station will be designated as an M-Station, authorized to undertake automotive exhaust repair projects. Below are the relevant details: 1. Practical Testing: Nitrogen oxides (NO), carcinogenic gases emitted by motor vehicles, are 20 to 30 times higher than the Euro 3 emission standards. Primary pollutants such as hydrocarbons (HC) and nitrogen oxides (NO) emitted by motor vehicles undergo photochemical reactions under sunlight, forming more toxic secondary pollutants—photochemical smog. A 2014 research report by the Chinese Academy of Sciences indicated that this type of photochemical smog constitutes the highest proportion in haze. 2. Normalization: Due to the rapid and extensive development of China's automotive industry chain, emissions from motor vehicles have sharply increased in the atmosphere, making severe regional haze a normalized phenomenon.

Which is more upscale, the Mercedes-Benz G-Class or the Cayenne?

The Cayenne and the Mercedes-Benz G-Class are different types of SUVs. In terms of space and comfort, the Cayenne performs better, while the G-Class excels in off-road capability and head-turning appeal. The G-Class is a body-on-frame off-roader with three differential locks, offering superior performance and power compared to the Cayenne. Here are some additional details: 1. Mercedes-Benz G-Class: (1) Exterior: The design is very stylish, with clean lines, a spare tire mounted on the rear door ("small backpack"), and AMG wheels and seats. (2) Interior: The interior is minimalist, with simplified design and craftsmanship. Most operations can be performed on a large central screen. (3) Space: The high roofline ensures the cabin doesn’t feel cramped. However, there are storage boxes under both front seats. The trunk space is very generous. 2. Cayenne: (1) Exterior: Fashionable and beautiful, with excellent body proportions. The lines are not overly sharp, but they complement the overall design perfectly. (2) Interior: The cabin is decent, featuring an older-generation "aircraft cockpit" style interior, and the center console is acceptable. (3) Space: The Cayenne 3.0T offers a great sense of space, comfortably seating five passengers. As an SUV, it provides ample headroom. However, the internal storage space is limited, and the trunk is relatively small.

What to Do After Driver's License Revocation?

If your license was revoked due to accumulating 12 penalty points from traffic violations or failing to renew an expired license, you can immediately apply for retraining and retake the exams to obtain a new driver's license. For those whose licenses were revoked for drunk driving or driving commercial vehicles under the influence of alcohol, they may reapply after five years. If the license was revoked for drunk driving a commercial vehicle, reapplying is permitted after ten years. However, if a major traffic accident occurred due to drunk or alcohol-impaired driving that constitutes a crime, the offender is permanently barred from reapplying for a driver's license. Retake process after license revocation: You must reapply after the revocation period ends. This involves retaking all four driving tests (Theory Test, Field Test, Road Test, and Safety Test). Passing all four exams qualifies you for a new license. Common revocation scenarios: Driving without displaying a valid license plate or using an expired temporary plate results in immediate revocation. Obstructing, forging license plates, or using fake temporary plates also lead to revocation. Driving commercial vehicles under the influence of alcohol or while intoxicated will get your license revoked. Drunk or impaired driving causing a major accident classified as a crime results in permanent revocation with no chance of reapplying.

Is the Buick Excelle fuel consumption high?

The average fuel consumption of the Buick Excelle is 8.4 liters per 100 kilometers, which is not considered high and falls into the medium range. Factors affecting fuel consumption: 1. Weight: The relationship between vehicle weight and fuel consumption is directly proportional. A 10% reduction in vehicle weight will correspondingly reduce fuel consumption by several percentage points. 2. Design: A smaller aerodynamic drag on the vehicle body will significantly reduce fuel consumption, and these two factors are also directly proportional. 3. Thermal efficiency: Strive to improve the engine's thermal efficiency. Generally, the thermal efficiency of gasoline engines (the proportion of fuel converted into useful work) reaches over 30%, while diesel engines exceed 40%. This is the main reason why diesel engines have lower fuel consumption than gasoline engines. The ratio of engine power to displacement is called the power per liter, indicating how much power the engine can generate per liter of displacement. The higher this ratio, the more advanced the engine technology. 4. Vehicle condition: Good vehicle condition is fundamental to fuel efficiency. Many drivers take great care of their vehicles, but due to a lack of automotive knowledge, their care is often limited to keeping the car clean, while other aspects are frequently neglected. In fact, scientific maintenance can help achieve fuel-saving goals. For example, wheel bearings should be lubricated regularly, but some owners are unaware of this until the bearings wear out. 5. Road conditions: Driving conditions are an important factor affecting fuel consumption. Every car has its own "economical speed," generally designed within the range of 70 to 90 kilometers per hour. If the car can move smoothly within this speed range in urban areas, the fuel consumption should be close to the test values obtained in standard test environments. When the car moves slower than a bicycle, fuel consumption increases significantly. 6. Driving habits: Incorrect driving habits can lead to a significant increase in fuel consumption. With the advent of the automobile era, there are more and more non-professional drivers, which inevitably leads to a major problem: incorrect driving habits result in higher vehicle fuel consumption. This impact is even greater on large-displacement vehicles.
