What are the four fundamental modular architectures of Geely Automobile?

Geely Automobile has introduced four global fundamental modular architectures (BMA, CMA, SPA, and SEA). Modular architecture divides a complete automobile structure into several modules, each assembled with components, and then integrates these modules together. BMA for A-segment vehicles: It is a compact modular architecture entirely independently developed and designed by Geely, meeting international technical standards. It retains the inherent high flexibility and scalability of the CMA–Compact Modular Architecture, initially co-developed by Geely Automobile Group and Volvo Cars. CMA for mid-size vehicles: This is the first mid-size vehicle fundamental modular architecture led by Volvo and co-developed with Geely, specifically designed for mid-size vehicles. It can cover products from A to B-segment vehicles. SPA for mid-to-large SUVs: SPA is Volvo's proprietary production platform. SEA for pure electric vehicles: The SEA architecture is currently the most extensive pure electric architecture globally, with a wheelbase range from 1800mm to 3300mm, covering all vehicle sizes from A to E-segment. It meets all styling requirements for sedans, SUVs, MPVs, compact city cars, sports cars, pickup trucks, and future mobility vehicles.

What are the common faults of automobile steering gears?

Common faults of automobile steering gears include the following: 1. Abnormal noise during steering. Abnormal noise during steering is caused by mechanical parts, such as damage to the kingpin and bushing, or damage to the column thrust bearing. During inspection, you can turn the steering wheel left and right to observe the location of the noise for disassembly and inspection. 2. Oil leakage from the steering gear. Oil leakage from the steering gear usually occurs in a few locations: the upper cover of the steering gear, the side end cover, and the connection between the steering shaft and the arm. These three parts all have sealing rings, and the issue can be resolved by replacing the new oil seal and sealing ring. 3. Difficulty in returning to position. Vehicles have the function of automatic steering return. For hydraulically assisted cars, the automatic return function is somewhat weakened due to the hydraulic damping effect, but a certain degree of automatic return capability should still be maintained. 4. Power steering pump oil leakage. If oil leaks from the rear cover of the power steering pump, it is obviously due to damage to the rear cover sealing ring.

What is the maximum tire size that can be modified for the X-Trail?

The maximum tire size that can be modified for the X-Trail is 235/55-R17. Any wider or larger than this may cause rubbing against the vehicle body. Tires are an essential component of a car, and you will see a series of letters and numbers on them. The markings on the tire sidewall include the tire brand, tire type, tire size, the maximum speed the tire can withstand, the production year of the tire, and more. For example, 235/55-R17. Tire width: 235 refers to the tire width of 235 millimeters. Tire aspect ratio: 55 refers to the tire aspect ratio, which is the ratio of the height from the rim to the tread of the tire to the maximum width of the tire section, expressed as a percentage. In other words, the height is 55% of the width. Radial tire and rim diameter: R stands for radial tire, commonly known as "steel-belted tire." A radial tire is a new type of tire where the carcass cords are arranged in a radial direction, and the belt layer, with cords arranged circumferentially or nearly circumferentially, tightly wraps around the carcass. It consists of six main parts: the tread, carcass, sidewall, belt layer, bead, and inner liner. 17 represents the rim diameter of 17 inches.

What does 91 and 95 mean on the fuel tank cap of Audi A6L?

Audi A6L fuel tank cap showing 91 and 95 means this vehicle must use gasoline with octane ratings between 91-95. The differences between 92 and 95 octane gasoline are as follows: Different compositions: 92 octane gasoline contains approximately 92% isooctane and 8% n-heptane, while 95 octane gasoline contains about 95% isooctane and 5% n-heptane. Isooctane has better anti-knock properties, whereas n-heptane has poorer anti-knock performance. Therefore, higher octane numbers indicate higher anti-knock quality. Each engine is factory-rated with specific anti-knock requirements based on its performance characteristics, determining which octane gasoline should be used. Price difference: 95 octane gasoline is slightly more expensive per tank than 92 octane. Performance difference: Higher-octane 95 gasoline is suitable for engines with higher compression ratios. As these engines increase speed, ignition timing advances. When reaching a critical point, pre-ignition may occur where fuel-air mixture combusts before spark plug ignition - this phenomenon is called "knocking." Increasing gasoline's octane rating effectively improves anti-knock performance.

What should be noted when obtaining a driver's license for the first time?

For first-time driver's license holders, please note the following points: 1. The first year is considered a probationary period for new drivers. If you accumulate 12 penalty points during this probationary period, your license will be revoked. After revocation, you must reapply for training, take the exams again, and obtain a new license. 2. During the probationary period, if you need to drive on highways, you must be accompanied by a driver with more than 3 years of driving experience in the front passenger seat. 3. After completing the first-year probationary period, there's no need to replace your license; you can continue using it. 4. When your license reaches 6 years, you must undergo an annual review and license renewal. (According to the expiration date indicated at the bottom of your original license, you should visit the local vehicle management office or district traffic police departments within 90 days prior to the expiration date to complete the annual review and renewal procedures). 5. If out-of-province trainees wish to transfer their license back to their home province, they must wait until the one-year probationary period is over before applying for the transfer procedures at the local vehicle management office. 6. For those upgrading their license category, the annual review and renewal must be processed within the validity period indicated at the bottom of the original license.

What are the causes of the high-mounted brake light illumination failure?

The following is a related introduction to the causes of the high-mounted brake light illumination failure: 1. Fault diagnosis: Based on the high-voltage breakdown of the drive chip and the failure analysis of the breakdown location of the faulty component, it is preliminarily suspected that there was a high-voltage interference level or electrostatic surge voltage in the high-mounted brake light circuit when the fault occurred. The focus of the investigation should be on the source of the impact voltage and the operating conditions. 2. Cause analysis: Using a test vehicle with normally functioning high-mounted brake lights, frequent switching of the rear wiper while the high-mounted brake light was illuminated resulted in the high-mounted brake light malfunctioning after multiple operations, consistent with the fault observed in the road test vehicle.
