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.

How to Maintain a Tesla Model 3?

Tesla Model 3 is a pure electric vehicle, and its maintenance only requires checking the battery and replacing the windshield washer fluid. During daily use, it is important to regularly inspect the condition of the tires and brakes to prevent potential safety hazards. Below are the relevant details: 1. Maintenance Interval: The maintenance interval for pure electric vehicles is generally every 10,000 kilometers or once a year. 2. Precautions: When using a pure electric vehicle, maintain good driving habits and avoid charging in extremely cold environments. It is best to use slow charging and fully charge the battery in one go to extend its lifespan. If the vehicle is not used for an extended period, charge it regularly to prevent battery depletion.

Can people with color weakness get a driver's license?

People with color weakness can get a driver's license because traffic regulations only prohibit those with red-green color blindness from obtaining a driver's license and do not specify that color weakness disqualifies someone. In addition to color discrimination ability, the driver's license test also has vision requirements for the eyes. For example, ordinary cars require both naked eyes or corrected vision to be above 4.9 on the logarithmic visual acuity chart. Color weakness, also known as anomalous trichromacy or color vision deficiency, is a mild form of color blindness where individuals can recognize colors but with reduced sensitivity. Below is more relevant information: 1. Legal basis: According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," for a C1 driver's license, applicants must have no red-green color blindness. Vision requirements: Both naked eyes or corrected vision must reach 4.9 or above. 2. Color weakness is a mild form of color blindness and is not equivalent to color blindness: Color weakness, also known as anomalous trichromacy or color vision deficiency, is a mild form of color blindness where individuals can recognize colors but with reduced sensitivity. People with color weakness have poorer color discrimination ability and can only see colors when they are highly saturated; they can only distinguish hue changes when there is a significant difference in wavelength. On the other hand, color blindness is the complete inability to distinguish certain or all colors, which has a significant impact on life and work. Color weakness is slightly better than color blindness, and the ability to discriminate colors can be improved by wearing color blindness correction glasses. Since there are many such products on the market, some of which are substandard, it is recommended not to choose cheap options but to select high-quality, certified products.
