What does excessive HC in vehicle exhaust mean?

How many labels should be affixed on the car window?

Two labels are required: the Motor Vehicle Inspection Compliance Label and the Compulsory Insurance Label. Below is more information about these two labels: 1. Compulsory Insurance Label: According to laws and regulations, this is insurance that must be purchased by individuals or entities within the specified scope. It mandates that motor vehicle owners or managers purchase corresponding liability insurance, thereby increasing the coverage rate of third-party liability insurance. In the event of an accident, compulsory insurance can provide timely and basic protection to the greatest extent for victims of traffic accidents. 2. Motor Vehicle Inspection Compliance Label: A green environmental inspection compliance label (commonly known as the green label) is issued to motor vehicles equipped with spark-ignition engines (mostly gasoline or natural gas vehicles) that meet National Standard I or above, and to motor vehicles equipped with compression-ignition engines (mostly diesel vehicles) that meet National Standard III or above. A yellow environmental inspection compliance label (commonly known as the yellow label) is issued to other motor vehicles that comply with the emission standards at the time of manufacture.

Will the 4S shop arrange a replacement car for customers during car repairs?

If the repair time exceeds 5 days, the 4S shop will arrange a replacement car for customers. If it is less than 5 days, a replacement car is generally not provided. According to Article 19 of the "Regulations on the Responsibility for Repair, Replacement, and Return of Household Automobile Products," during the warranty period of household automobile products, if each repair due to quality issues (including waiting time for repair spare parts) exceeds 5 days, the consumer should be provided with a replacement car or reasonable transportation cost compensation. The repair time is calculated from the time the consumer and the repairer confirm the repair until the repair is completed. A repair that takes less than 24 hours is counted as one day. If the 4S shop indeed cannot provide or has no replacement cars available, you may consider nearby 4S shops that have been operating for a shorter time. Generally, long-established and large-scale 4S shops have more vehicles sent for repairs, and replacement cars are usually all allocated, while newer 4S shops may still have replacement cars available.

Why does the tire pressure warning light remain on after a tire repair?

It indicates that the air pressure in the recently repaired tire is abnormal (usually overinflated). It must be adjusted to match the pressure of the other three tires. The tire pressure warning cannot be cleared manually. The vehicle's tire pressure warning system alerts when tire pressure is either too high or too low. It is recommended to check the pressure of all four tires. The standard tire pressure values are usually marked on the driver/passenger door edges or fuel cap, typically 2.2 bar for front tires and 2.4 bar for rear tires. After confirming all tires are properly inflated: 1. Use an OBD scanner to clear the fault code. 2. Drive at speeds above 30 km/h for some time to reset the system. Additional information: Tire pressure maintenance: Generally, car tires should be checked at least once a month. Seasonal adjustments are particularly important, with ideal times being November and May. In November when winter approaches, tire pressure usually decreases and should be slightly increased. In May when temperatures rise, check if pressures are normal. Note: Unless the tire pressure significantly exceeds standard range, avoid deliberately reducing pressure during this period.

What are the reasons for slow tire air leakage but unable to find the leak?

The following are the reasons for slow tire air leakage but unable to find the leak: 1. Foreign objects puncturing the tire: This is the most common situation. Objects that easily puncture the tire include nails, screws, wires, glass fragments, sharp stones, and tiles. Among these, nails and screws are the most likely to puncture the tire, causing a slow leak. If the tire is punctured by a foreign object, careful observation of the tire surface can reveal it. If the puncture location is hidden, you can sprinkle water on the tire surface to find bubbles or hear a "hissing" sound of air escaping. 2. Leaky valve core: If you pour water on the valve core and see bubbles, it indicates a leaky valve core. In this case, simply loosen the dust cap a bit, as being too tight can press against the valve core and cause air leakage. 3. Damage to the tire sidewall: Besides the tire tread being easily punctured by foreign objects, the sidewall and inner edge of the tire can also be damaged. Some drivers have poor spatial awareness and often scrape the tire sidewall against the curb when parking. Once or twice may not cause issues, but repeated occurrences can wear down the tire sidewall.

Does All-Purpose Cleaner Damage Car Paint?

All-purpose cleaner, after all, contains chemical substances that can cause certain damage to car paint and interiors. More details are as follows: Definition of All-Purpose Cleaner: All-purpose cleaner, also known as multi-purpose cleaner, is categorized into heavy-duty and light-duty types, containing various composite chemical ingredients. Generally, car wash shops use large industrial packaging of these cleaners, which can be diluted and applied to areas like wheel rims and tires. Although the cleaning power of all-purpose cleaner is outstanding, its corrosiveness is also very strong. Even diluted solutions with low concentrations can cause irreversible damage to paint surfaces and interiors with long-term use. Pros and Cons of All-Purpose Cleaner: All-purpose cleaner is mainly used for cleaning interiors and has strong stain-removing capabilities, which is why many car wash shops use it. However, it should be noted that many all-purpose cleaners on the market today are alkaline and of inferior quality, with relatively low prices. Because they are alkaline, their stain-removing effect is good, but they can harm the interior. Safe products for cleaning interiors need to be neutral, but since neutral products are more expensive, many service shops rarely use them to save costs.

How to Check Traffic Violations on the Same Day?

Same-day traffic violations are generally not available for checking. It usually takes 3 to 7 days for a motor vehicle violation to be recorded, and the latest should not exceed 13 working days. Below is some information about violation handling: 1. Time Frame: Vehicle owners need to go to the local traffic police station to handle the violation within 15 days of receiving the penalty notification message. If not handled within 15 days, a late fee of 3% per day will be charged, but the total late fee will not exceed double the original fine amount. It is advisable to handle it early to avoid unnecessary penalties. 2. Confirmation Method: The fastest and most effective way to know if you have run a red light is to check for red-light violations at the vehicle management office or traffic police station. You need to bring important documents such as your driver's license, vehicle license, and ID card. All three are essential, and it is best to prepare some cash as well, so that if a violation is found, you can immediately proceed with the necessary formalities.
