How Long Can a Temporary License Plate Be Used for a Car?

Car temporary license plates cannot be used for more than 15 days, and the owner should promptly apply for a formal license plate from the vehicle management authority. After expiration, penalties may include vehicle impoundment, a fine of 200 yuan, and a deduction of 3 points. The characteristic of a temporary license plate lies in its temporary nature. While formal license plates can be permanently valid, once a temporary license plate expires, the holder cannot drive on the road without renewal; otherwise, it constitutes a traffic violation. New car temporary plates can be extended, with a maximum of three extensions totaling 21 days. New cars require temporary license plates to be driven on the road. Temporary license plates serve as a transitional phase before obtaining formal plates, with the same legal effect as formal plates. However, temporary plates are time-sensitive and become invalid once formal plates are issued. Temporary license plates are divided into two types: one for temporary driving within the administrative jurisdiction, issued for a validity period not exceeding 15 days, colored blue; the other for temporary driving across administrative jurisdictions, issued for a validity period not exceeding 30 days, colored yellow. The procedures for applying for yellow and blue temporary license plates are the same, requiring the following documents: original and photocopy of the vehicle owner's identity proof; original and photocopy of the vehicle qualification certificate; original and photocopy of third-party liability insurance (traffic compulsory insurance); original and photocopy of the vehicle purchase invoice. Types of temporary license plates: Motor vehicle temporary license plates include four categories: temporary plates for administrative jurisdictions, temporary plates for cross-administrative jurisdictions, temporary plates for testing purposes, and temporary plates for special-type motor vehicles. Motor vehicle temporary license plates consist of two cards, with the front displaying the plate number and validity period, and the back showing detailed vehicle information. Temporary license plates cannot be lent to others.

What are the reasons for no air coming out of the car vents?

The reasons for no air coming out of the vents may include abnormal connection of the vent switch, blown fuse of the air conditioning, blocked air conditioning vents, or malfunctioning of the air conditioning motor fan. Below are the detailed explanations: 1. Clogged air conditioning filter: The most common reason for no air coming out of the air conditioning is a clogged air conditioning filter. Since the outside air usually passes through the air conditioning filter before entering the car interior, the main function of the air conditioning filter is to isolate dust, particles, moisture, and other attachments in the air. It also provides strong sterilization and deodorization effects, ensuring that passengers do not inhale harmful gases that could threaten their health and driving safety. Generally, the air conditioning filter is installed above or below the blower. Therefore, it can be said that air must pass through it to enter the car. If the air conditioning filter is clogged, poor air circulation will naturally result in no air coming out. 2. Damaged blower: The blower is an important part of the air conditioning system, as the air circulation inside the car relies on its operation. When using the air conditioning at high fan speeds, a buzzing sound can often be heard coming from under the passenger seat. This is the sound of the blower working. The higher the air demand, the faster the blower needs to draw in air. Therefore, if the blower is damaged, it may not draw in enough air or fail to draw in air at all, preventing air from being blown out and causing the air conditioning to not work. 3. Faulty air door, computer, or switch: The air door is located inside the air duct and, being made of plastic, may get stuck or break. When the air door cannot open, the air drawn in by the blower cannot flow out through the vents, resulting in no air coming out of the air conditioning.

Does using 95 octane gasoline in a car designed for 92 octane have any impact?

Using 95 octane gasoline in a car designed for 92 octane has no short-term impact, but in the long run, it will reduce the service life of the car's ignition system, fuel injectors, and spark plugs, leading to an earlier need for major repairs. The appropriate gasoline grade can be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, those between 10.0-11.5 should use 95 octane gasoline, and if the compression ratio is even higher, 98 octane gasoline is recommended. However, with the application of some new technologies, the compression ratio alone cannot determine the gasoline grade to use. High compression ratio engines can also be tuned to use lower octane gasoline because, besides the compression ratio, 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. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after the current tank is used up. However, long-term use of the wrong gasoline grade can have the following impacts: For cars designed for lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance in practice. For cars designed for higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If the gasoline ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance will make the engine run very unstably. If the knocking is imperceptible, it only increases noise and does not significantly damage the engine. However, if the knocking is noticeable, it indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring. Considerations when choosing gasoline: Select gasoline with appropriate volatility based on the car's operating environment temperature. Gasoline with good volatility makes cold starts easier and allows the engine to warm up smoothly. However, if the volatility is too high, it can easily cause vapor lock in the fuel lines, preventing the fuel pump from delivering gasoline properly and causing the engine to stall. Choose gasoline based on its lead content.

How to handle an Audi Q3 trunk that won't close?

Audi Q3 trunk that won't close can usually be fixed by simply opening the trunk lock mechanism and adding some lubricating oil. The main reason for this issue is lack of lubrication in internal components. If the trunk's locking mechanism is damaged or deformed, it may get stuck when closing. In such cases, immediate repair is necessary, and parts replacement might be required when needed. The Audi Q3 is a compact entry-level luxury SUV with body dimensions of 4385mm in length, 1831mm in width, and 1608mm in height, featuring a 2603mm wheelbase and equipped with permanent four-wheel drive system.

How many kilometers can a car exceed its maintenance interval?

Car maintenance can be delayed by approximately 1,000 kilometers. However, during the warranty period, it is essential to strictly adhere to the maintenance schedule outlined in the manual. Otherwise, the 4S dealership may refuse to provide free warranty repairs or free claims for issues that arise during the warranty period, citing overdue maintenance. Different car brands have varying maintenance intervals in terms of both time and mileage. Japanese and Korean car models typically require maintenance every 5,000 kilometers, while European and American models may have intervals of 7,500 kilometers or even 15,000 kilometers. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing.
