What are the reasons for the chip shortage in automobiles?

The reasons for the chip shortage in automobiles: Modern cars are becoming increasingly intelligent, requiring more chips than before; the impact of the pandemic has led to explosive growth in the consumer electronics industry, while chip production capacity has significantly decreased; consumer electronics products require more chips than automobiles. Modern cars are becoming increasingly intelligent, requiring more chips than before: In the past, the core components of cars were mechanical parts, such as engine components and transmission parts, which were very difficult to manufacture. In recent years, almost all car brands have been launching smart cars with directly noticeable intelligence, such as large central control screens and head-up displays, all of which require chips. Many other unseen components in cars that provide these features also require chips, such as MCUs and various controllers. With the increase in functional parts that need chips, the demand for chips by car manufacturers has also significantly increased. The impact of the pandemic has led to explosive growth in the consumer electronics industry, while chip production capacity has significantly decreased: Over the past two years, due to the pandemic, many chip factories and downstream manufacturers have closed or reduced production. These enterprises are mainly located in Taiwan, Southeast Asia, and the United States, regions that have been severely affected by the pandemic, preventing factories from operating normally. Additionally, these factories occasionally experience disasters such as fires and cold waves, further reducing and destabilizing chip production capacity.

Can the film provided by 4S stores be applied?

If the film provided by the 4S store is from a reputable brand with good quality, it can be applied. However, if it is a low-quality film, it is recommended not to use it. Regarding whether the items given by 4S stores when picking up the car can be used, car owners need to be vigilant and carefully assess the quality of these films. Car film refers to the film applied to the surface of car glass, and its functions include: 1. Blocking solar heat and blinding glare; 2. Reducing the load on the car's air conditioning system, improving fuel efficiency, and enhancing driving comfort; 3. Blocking UV rays to protect the skin of passengers from sunburn and slow down the fading, aging, and cracking of interior materials; 4. Enhancing driving safety by keeping glass fragments in place in case of breakage, preventing injuries; 5. Creating a private space to prevent others from peering in.

Should Original Steel Wheels Be Replaced with Aluminum Alloy?

Here is the relevant introduction about whether original steel wheels should be replaced with aluminum alloy: 1. Steel wheels: Steel wheels have strong load-bearing capacity (large trucks and buses all use steel rims), good toughness (they can automatically recover after slight deformation), relatively strong resistance to metal fatigue, and are low-cost. Usually, steel wheels are equipped with a plastic cover on the outside for aesthetic purposes. 2. Aluminum alloy wheels: Aluminum alloy wheels are lighter, harder, and come in more styles due to differences in material and manufacturing processes. 3. Differences: Compared to steel wheels, aluminum alloy wheels are actually harder, so under the same strength, they absorb energy less effectively than steel wheels and are more prone to fracture. Additionally, due to reasons like metal fatigue and aging, aluminum alloy wheels have a slightly shorter lifespan than steel wheels.

Does Remote Starting the Air Conditioner Harm the Car?

Remote starting the air conditioner can harm the car. Specific details are as follows: 1. Reason: Turning off the engine before shutting down the air conditioner is harmful to the engine. This is because when the vehicle is started again, the engine will start with the load of the air conditioner, which can damage the engine due to the high load. 2. Best practice: Turn off the air conditioner a few minutes before reaching the destination. This allows natural air to circulate, helping the temperature inside the air conditioning ducts to rise and eliminate the temperature difference with the outside environment, thereby maintaining relative dryness in the air conditioning system and preventing mold growth. Additionally, it is recommended to wait two to three minutes after starting the vehicle, allowing the engine to be properly lubricated, before turning on the air conditioner.

How to Replace the Battery in a Baojun 610 Car Key?

Simply use a tool to pry open the key's outer shell, and then you can replace the battery. Below are some relevant details: 1. Car remote keys contain batteries, which typically last 2 to 3 years. If the battery in the remote key is dead, it needs to be replaced. Failure to replace it will affect the owner's normal use of the car. 2. When replacing the battery, open the key, check the model of the old battery, and then purchase a new battery of the same model to install. 3. When using the remote key, avoid exposing it to water, as most car remote keys are not waterproof. 4. During regular use, try to avoid remote operations from long distances to conserve battery power. Frequent long-distance remote use will increase power consumption and reduce the battery's lifespan. 5. When opening the shell to replace the battery, be careful not to damage the chip. If the chip is damaged, you will need to have it reprogrammed, which can be expensive. If the chip is damaged, you can have it reprogrammed at a 4S shop or a specialized car key programming service. 6. In daily use, keep the spare key at home. If the main key is damaged or lost, the spare key can still unlock the car door and start the engine.

What Type of License is a Motorcycle License?

Below is a detailed introduction to motorcycle licenses: 1. For three-wheeled motorcycles, a Class D license is required. 2. For general motorcycles, a Class E license is required. 3. For light motorcycles, a Class F license is required. A Class F license (light motorcycle) applies to motorcycles with an engine displacement ≤50ml and a maximum design speed ≤50km/h. 4. A Class D license allows the holder to drive all three types of motorcycles mentioned above. A Class D license (ordinary three-wheeled motorcycle) applies to three-wheeled motorcycles with an engine displacement >50ml or a maximum design speed >50km/h and permits driving vehicles covered by Class E and F licenses. 5. A Class E license allows the holder to drive the latter two types of motorcycles. A Class E license (ordinary two-wheeled motorcycle) applies to two-wheeled motorcycles with an engine displacement >50ml or a maximum design speed >50km/h and permits driving vehicles covered by a Class F license.
