What are the vision requirements for the C1 driver's license physical examination?

For the C1 driver's license physical examination, the naked or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. The following are the vision requirements for a driver's license: 1. Regulations: For applying for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or tram driving licenses, the naked or corrected vision of both eyes must reach 5.0 or above on the logarithmic visual acuity chart. For other driving license types, the naked or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart. 2. Others: For those with monocular vision impairment, if the naked or corrected vision of one eye reaches 5.0 or above on the logarithmic visual acuity chart, and the horizontal field of vision reaches 150 degrees, they can apply for a motor vehicle driver's license for small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, or special small automatic transmission passenger cars for the disabled.

What grade of gasoline should a BMW Z4 use?

BMW Z4 should use 95-octane gasoline, as this grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, BMW Z4 owners can also find this information on the fuel tank cap, which is usually labeled. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the use of new technologies, the compression ratio alone cannot determine the appropriate gasoline grade, as high-compression engines can also be tuned to use lower-octane gasoline. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If a BMW Z4 occasionally uses the wrong gasoline grade, simply switching back to the correct grade after use is sufficient. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles designed for lower-octane gasoline, using a higher grade will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher-octane gasoline, using a lower grade can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but severe knocking indicates serious engine conditions. The vibrations not only affect driving stability but can also cause abnormal wear on the pistons and cylinders, potentially leading to cylinder scoring in severe cases.

What is the difference between China V and China VI symbols?

The difference between China V and China VI emission symbols is: they are displayed on the vehicle compliance label, where 'China V' represents China V vehicles and 'China VI' represents China VI vehicles. The differences between China V and China VI emissions are as follows: Different emission standards: China VI emission standards are more than 30% stricter than China V. Excluding the influence of operating conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: The China V standard was implemented nationwide on January 1, 2017. The China VI standard has been implemented since July 1, 2019. Different principles: During the China V phase, diesel and gasoline vehicles had different emission standards, but China VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing departments: The China V standard was issued by the Ministry of Environmental Protection. The China VI standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: China V is represented by 'V'; China VI is represented by 'VI'. Different monitoring requirements for plug-in hybrid vehicles: Compared to China V, China VI has improved monitoring requirements for plug-in hybrid vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. China V standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM fine particles per kilometer driven. China VI has two standards: China VIa and China VIb. They are as follows: China VIa standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM fine particles per kilometer driven. China VIb standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM fine particles per kilometer driven. Affected by the China VI emission policy, although China V vehicles are not currently restricted from normal use, such as road restrictions or license plate limitations, their resale value will be significantly impacted. For car owners, if they purchase a truck for freight transport with a loan, the vehicle's depreciation after repaying the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China VI vehicles, which have a longer service life and more road rights, are more advantageous.
