What are the main functions of a car air conditioning system?

Car air conditioning is the abbreviation for the air conditioning system in a vehicle. Below are the regulation functions of a car air conditioning system: 1. Temperature regulation: This is the primary function of car air conditioning. In summer, the cooling system produces cold air to lower the temperature inside the cabin. In winter, except for large commercial vehicles that use independent combustion heaters for heating, other vehicles generally utilize the residual heat from the engine for heating. 2. Humidity regulation: The humidity inside the cabin should generally be maintained between 30% and 70%. Standard car air conditioning systems do not have the function to regulate cabin humidity; only advanced luxury vehicles equipped with integrated heating and cooling systems can achieve this through ventilation devices. 3. Airflow regulation: When the temperature is suitable, the airflow speed should be limited to a certain range. The speed can be adjusted appropriately based on passengers' living environment, age, health condition, and temperature preferences. 4. Air purification: The quality of air inside the cabin is an important factor in ensuring comfort.

What Causes the Peugeot 408's Central Display to Show an Engine Fault?

Peugeot 408's central display showing an engine fault is caused by poor combustion state, poor fuel quality, unclean engine cylinder interior, and carbon deposits. Poor Combustion State: Poor engine combustion state is the main reason for the engine fault light to illuminate. In automotive design, to ensure the engine operates in good condition and maintains a normal working lifespan, oxygen sensors are installed to monitor the engine's combustion state. Once the combustion state deteriorates, it not only pollutes the environment but also leads to fuel wastage and excessive engine wear. Poor Fuel Quality: The engine has specific requirements for fuel quality indicators, especially as regulations increasingly demand higher performance from engines. In practice, some gas stations cannot fully comply with these standards to provide fuel that meets the requirements of high-performance engines, resulting in the engine fault light illuminating. Unclean Engine Cylinder Interior and Carbon Deposits: After a certain period of use, carbon deposits accumulate inside the engine. These deposits alter the engine's design parameters and, due to their unstable nature and heat retention, can cause uncontrolled ignition, leading to engine knocking. In such cases, the engine fault light will also illuminate. Solutions for Engine Faults: Engine Cleaning: Once the engine fault light comes on, the driver should promptly visit a repair shop to clean the carbon deposits using specialized cleaning agents. Using Higher Octane Fuel: After cleaning the engine, since most cars compliant with China's National IV emission standards have a compression ratio above 10.0, they are not suitable for long-term use of gasoline below 95 octane. To maintain the engine's good working condition, drivers can opt for 95 or 97 octane gasoline, which usually resolves the issue of the engine fault light illuminating.

How to Detect Air Leakage in Car Tires?

Methods to detect air leakage in car tires include: 1. Remove the valve cap and spray soapy water directly onto the valve to observe if bubbles form; 2. Sprinkle water on the surface of the tire—hissing sounds or bubbling indicate the location of the leak; 3. Park the car on a flat surface and compare the tire pressure between the front and rear wheels to ensure they are equal. Tires must have good cushioning performance to absorb and dampen vehicle vibrations along with the suspension. Poor cushioning performance can affect ride comfort and the lifespan of other vehicle components. If you notice a decrease in tire pressure, use a tire inflator to add air before driving to a nearby repair shop for further inspection.

What is the difference between full-speed adaptive cruise control and adaptive cruise control?

Full-speed adaptive cruise control provides a simpler, more relaxed, and more enjoyable driving experience. Adaptive cruise control technology assists the driver in driving and relieves fatigue. Full-speed adaptive cruise control and adaptive cruise control have different speed limits and different natures. The following are specific introductions about the differences in speed limits and natures: Differences in speed limits: Full-speed adaptive cruise control can be used at any speed; adaptive cruise control can only be used at speeds above 40 km/h or 60 km/h. Differences in nature: Full-speed adaptive cruise control does not require the driver to touch the accelerator or brake pedal during vehicle operation; it completely releases the driver's right foot, thereby achieving a simpler, more relaxed, and more enjoyable driving experience. For models that cannot achieve full-speed cruise control, when the speed falls below the computer-set speed, the cruise control will automatically exit and hand over driving to the driver. Adaptive cruise control technology is based on active safety configurations and requires radar, ultrasonic, and infrared sensors to detect obstacles, pedestrians, and vehicles ahead. It assists the driver in driving and relieves fatigue. Automatic braking functionality is necessary to ensure precise distance control.

How to Turn On the Bluetooth of an ETC Device?

The method to turn on the Bluetooth of an ETC device: 1. The ETC Bluetooth switch is a button on the top of the electronic tag. Press the button to activate the Bluetooth of the electronic tag; 2. Insert and remove the ETC card twice in succession to turn on the Bluetooth of the ETC device. A successful activation is indicated by the Bluetooth switch indicator on the ETC electronic tag flashing or staying lit for about 2 minutes. Please complete the relevant Bluetooth connection as soon as possible. The Bluetooth function of the ETC device is only used for ETC activation or recharge. Automatic deduction through the high-speed ETC lane does not require the Bluetooth to be constantly on. The ETC device has an internal battery and is charged externally via solar power. For solar-powered ETC devices that are not frequently used, it is recommended to charge them every 3 months to prevent natural discharge of the internal battery.

How to Remove an ETC Device?

Method for removing an ETC device: Since there's double-sided tape on the back of the device, you can use a hair dryer to heat it up, then gently pry it off with a small plastic scraper, and finally wipe it clean with a cloth. Note that self-removal will deactivate the ETC device, requiring reactivation at the issuing institution with the vehicle's registration certificate. ETC stands for Electronic Toll Collection, an automated system that identifies vehicles, records information, and deducts fees from pre-linked IC cards or bank accounts when passing through toll stations.
