The evaporator in a car's air conditioning system, also known as the evaporator core, is essentially a heat exchanger. When refrigerant enters the evaporator, it expands and absorbs heat, thereby cooling the evaporator. At this point, the air blown by the blower passes through the evaporator, resulting in cold air being discharged from the air conditioning vents. The primary function of the evaporator is to cool the air delivered by the blower. Below is some relevant information about car air conditioning systems: 1. The car air conditioner is a crucial comfort feature in vehicles, and its working principle is relatively straightforward. 2. The refrigerant commonly used in car air conditioners is R134a, which requires periodic replacement. If the refrigerant is not replaced for an extended period, the air conditioning system's cooling performance will deteriorate, and the cooling speed will slow down. 3. When replacing the refrigerant, it is essential to visit a professional service provider and use specialized equipment, as car owners cannot perform this task themselves.

Is the Vios an imported car or a joint venture car?

It is a domestically produced joint venture car. Imported cars do not have the FAW logo. Joint venture and domestic mechanical processing: It is undeniable that domestic cars are indeed very generous in terms of materials, paint, and interior, but they lose in the assembly standards of the products. For example, joint venture cars have very strict requirements on the body seams and component tolerances, and some Japanese brands even have requirements for the cleanliness of the car assembly workshop. Joint venture and domestic core components: The engine is the heart of a car, and its quality determines the consumer's driving experience. In recent years, domestic cars have made great progress in this area, but compared with joint venture cars, the difference lies in the average level and durability.

What is Air Compressor Oil?

Air compressor oil is a liquid lubricant. The following is a relevant introduction about engine oil: 1. Introduction: Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber. It is often referred to as the "blood" of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing certain new characteristics. Additives are an essential part of the lubricant. 2. Requirements: As a type of machinery, an engine has common requirements for lubricants similar to general machinery, such as appropriate viscosity, certain anti-oxidation, anti-wear, anti-corrosion, and viscosity-temperature properties. However, an engine is also a special type of machinery, and its requirements for lubricants have unique aspects.

Is the engine of Geely Vision the same as Toyota's?

Geely initially used Toyota's 8A engine. Historical Background: Initially, they conducted reverse engineering on Toyota's 8A engine, followed by Mitsubishi's 4G series engines. Later, they reverse-engineered Volkswagen's EA888 engine, which was applied to models like the Boyue and Borui. Some 2.4L engines were also purchased from Toyota. In recent years, Geely has developed its own engines, such as the 1.4T engine, which has shown good performance in terms of output power and stability. Domestic Technology: No, it's not the same. In engineering terms, this is called "reverse development," where the goal is to thoroughly study the design of the target model, avoid its design patents and features, and then redevelop it. Avoiding patents essentially means avoiding the core technologies of the engine, such as the stratified combustion technology in the 1.4TSI.

Can I use the Traffic Management 12123 App without My Physical Driver's License?

You can use the electronic driver's license from the Traffic Management 12123 App when you don't have your physical driver's license with you. The electronic driver's license has been implemented and is displayed through the Traffic Management 12123 App. Not only can you use the electronic driver's license in your own city, but you can also use it when driving to other cities. This means we no longer need to carry a physical driver's license when traveling. During inspections, presenting the electronic version of the driver's license is equivalent to showing the physical version. However, it's crucial to ensure that the driver's license is within its validity period. If the physical driver's license expires, the electronic version will also expire, and you must replace it within the specified time frame as required. The electronic driver's license can replace the original physical version for most procedures, including handling traffic management services, expanding passenger and freight transport services, and can be used independently during car rentals, insurance payments, and law enforcement inspections. Therefore, even without the physical driver's license, you can still drive normally. However, if your physical driver's license is temporarily suspended, you cannot use the electronic version. Due to various reasons, if the physical driver's license is in an abnormal state, such as being temporarily suspended or for other reasons, the information on the electronic driver's license might not be synchronized yet and may still show as normal, but it cannot be used. If you continue driving under these circumstances and are checked by traffic police, it will be treated as driving without a license. To present your electronic driver's license, open the Traffic Management 12123 App, click on the driver's license section at the top, and then find the electronic driver's license option. Here, you can also see the status and validity period of your electronic driver's license.
