An automotive air conditioning system mainly consists of the following components: 1. Refrigeration system: The compressor's function is to compress low-pressure vapor into high-pressure vapor, reducing the vapor volume and increasing the pressure. The compressor draws lower-pressure vapor from the evaporator and, after increasing the pressure, sends it to the condenser. 2. Heating system: A low-temperature heat medium is heated in the heat source, absorbs heat to become a high-temperature heat medium, and is then transported through pipes to the interior, where it releases heat through radiators to raise the indoor temperature. 3. Ventilation system: This system uses natural or mechanical methods to allow unobstructed airflow to pass through and reach the interior or a sealed environment, creating a sanitary, safe, and suitable air environment. 4. Air purification device: The air purification device can remove impurities and purify contaminated air. 5. Control system: The control system refers to a management system composed of a control subject, control object, and control medium, with its own goals and functions.

I usually help people repair cars. The automotive air conditioning system mainly consists of several key components, each of which is quite important. The compressor is like the engine—it compresses the refrigerant gas, driving the entire cycle. The condenser is usually located near the front radiator, cooling the hot gas into a liquid. The expansion valve or capillary tube controls the refrigerant flow, reducing the pressure. The evaporator is inside the car, absorbing heat to cool the air. The blower or fan blows cold air into the cabin. There are also pipes connecting them, circulating the refrigerant liquid, and the control panel allows me to adjust the temperature and airflow. These components work together to ensure reliable cooling. If the compressor fails, the AC won’t cool properly, so it’s important to check the belt and oil seals promptly. Performing maintenance before summer can save a lot of trouble.

Where is the car's three-way catalytic converter located?

The three-way catalytic converter is installed in the vehicle's exhaust system. Here is more information about the three-way catalytic converter: 1. The three-way catalytic converter can convert various major harmful substances in vehicle exhaust into harmless substances. 2. The vehicle is equipped with a three-way catalytic converter and an oxygen sensor device, which can transform harmful gases such as CO, HC, and NOx emitted from the vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 3. If the three-way catalytic converter is damaged, the secondary oxygen sensor will not be able to correctly provide data to the vehicle's computer, leading to either too lean or too rich fuel mixture concentration. A too lean mixture can cause ignition difficulties, weak driving, engine backfiring, etc., while a too rich mixture can increase fuel consumption, incomplete combustion, and severe carbon deposits in the cylinders and spark plugs. When such faults occur, the engine fault light should illuminate.

The first 12 months after a motor vehicle driver initially applies for a driver's license or adds a new vehicle class to their license is considered the probationary period. 2. When driving on highways during the probationary period, the driver must be accompanied by someone who has held a driver's license for the corresponding or higher vehicle class for more than three years. The accompanying driver should sit in the front passenger seat to provide guidance. If the novice driver is unaccompanied or the accompanying driver does not meet the requirements, a fine of 200 yuan will be imposed.

What are the length and width of the Baojun 510 windshield?

Baojun 510 windshield length is 1250mm, width is 650mm. Windshield manufacturing requirements: Car windshields are generally made as a single large curved piece with certain curvatures on all sides. This type of curved glass is a highly technical product in terms of both the manufacturing process and assembly, as it involves multiple factors such as vehicle model, strength, heat insulation, and installation. Windshield maintenance: During regular glass maintenance, choose appropriate windshield washer fluid based on the season and weather conditions. When the windshield surface appears blurry, cleaning with suitable washer fluid can significantly improve clarity. If you notice glare on the glass at night, it can also be wiped with washer fluid. Additionally, when driving on highways or in dusty conditions, washer fluid is consumed quickly, so it's important to replenish it promptly.
