Car air conditioners consist of four main components: the heating system, cooling system, ventilation and air purification system, and control system. The functions of these components are as follows: 1. Heating system: Increases the temperature inside the car and defrosts the front windshield. 2. Cooling system: Reduces the temperature and humidity inside the car. 3. Ventilation and air purification system: Regulates airflow and air exchange inside the car, and filters the incoming air. 4. Control system: Manages the operation of the air conditioning system to achieve heating, cooling, and ventilation.

The automotive air conditioning system mainly consists of several components: The compressor acts like the core engine, responsible for compressing the refrigerant into a high-temperature, high-pressure gas. Then, the condenser, located at the front of the car, dissipates heat to turn it into a liquid. The expansion valve or similar component reduces pressure to allow the refrigerant to flow. The evaporator near the cabin absorbs heat to cool the air. The fan blows out the cooled air, while the control circuit regulates the temperature. Driving in summer relies on it; otherwise, you might feel dizzy from the heat. It's recommended to clean the air filter once a year to prevent mold and odors. If the refrigerant leaks, the cooling effect will be poor, and you can go to a repair shop to top it up. Over years of driving, I've found that an efficient air conditioning system can also save some fuel costs. Proper maintenance overall can extend its lifespan.

What are the symptoms of insufficient transmission fluid in a car?

The symptoms of insufficient transmission fluid in a car include: 1. The most noticeable is a jerky feeling when shifting gears, with unsmooth gear changes; 2. When pressing the accelerator, the increase in engine RPM does not correspond proportionally to the increase in vehicle speed; 3. The transmission will overheat. If the transmission fluid is not replaced for a long time, it will become increasingly viscous, affecting heat dissipation and leading to excessively high temperatures, which over time can impact the transmission's lifespan. Transmission fluid deteriorates and evaporates under high-speed and high-temperature conditions, so it needs to be replaced regularly. Failure to replace it can accelerate wear and tear on mechanical components. Transmission fluid helps keep the gear system clean, lubricates the transmission components, and extends their service life.

Can replacing the original car lights with LED lights pass the annual inspection?

Replacing the original car lights with LED lights requires the addition of lenses to pass the annual inspection. The reason why modified car lights fail the inspection is that they are not equipped with lenses and directly install xenon or LED bulbs without proper housing. Additionally, bulbs with a color temperature exceeding 6000K also cannot pass the inspection. The annual vehicle inspection in China is primarily based on the National Standards of the People's Republic of China, focusing on four main aspects: appearance, exhaust emissions, lighting, and braking (including axle weight). Among the reasons for vehicles failing the inspection, a significant proportion is due to non-compliant lighting, but this is not because of the installation of xenon or LED bulbs. Instead, it is due to insufficient brightness and light transmittance of the lights, which are mainly caused by prolonged vehicle use, aging light circuits, or insufficient power supply.

How to Identify a New Car vs. a Stock Car?

Methods to identify a new car and a stock car are: 1. Check the manufacturing date: Every vehicle has a nameplate near the door that clearly indicates the manufacturing date. If the car was manufactured within the last three months, it is considered new; otherwise, it is a stock car. 2. Look at the date symbols on the car windows: These markings represent the manufacturing date of the glass. If they are inconsistent, it means a piece has been replaced. 3. Inspect the tire wear: New tires come with a layer of tread hairs that wear off easily. Check if all four tires still have these hairs when picking up the car. 4. Feel the inside of the exhaust pipe with your finger: If there are obvious black stains, it indicates the car has been driven for some time and might be a test drive vehicle. If the color is faint, there is no need to worry.

Where is the tire pressure reset button for the JAC Refine S3?

The tire pressure reset button for the JAC Refine S3 is located in the center of the dashboard. The black knob labeled 'set' is the tire pressure reset button. Pressing the 'set' button will reset the tire pressure monitoring system. The working principle of the tire pressure monitoring system involves an internal sensor installed on the tire hub. This sensor includes a bridge-type electronic pressure sensing device that detects air pressure, converting the pressure signal into an electrical signal, which is then transmitted via a wireless transmitter. The JAC Refine S3 is a compact SUV with dimensions of 4345mm in length, 1765mm in width, and 1640mm in height, with a wheelbase of 2560mm. In terms of suspension, the front suspension of this vehicle uses a MacPherson strut independent suspension, while the rear suspension employs a torsion beam non-independent suspension.

How often should a minivan be inspected?

A minivan should be inspected once a year within the first 5 years of use, and every 6 months after exceeding 5 years. For trucks and large or medium-sized non-operational passenger vehicles, the inspection is required once a year within the first 10 years, and every 6 months after exceeding 10 years. As for ordinary motorcycles, they should be inspected every 2 years within the first 4 years, and once a year after exceeding 4 years. Vehicle annual inspection is also known as motor vehicle inspection. Depending on the nature of the motor vehicle's use, the inspection items and scope may vary. Motor vehicle inspections include three categories: motor vehicle safety technical inspection, motor vehicle emission inspection, and comprehensive vehicle performance inspection.
