How to Define Stock Vehicles?

Stock vehicles is just a term in the automotive sales industry, referring to new cars that have not been sold for a long time after leaving the factory, with extended inventory periods. There are no national regulations specifying how many months constitute a stock vehicle, but the industry generally considers cars that have been in inventory for over three months or more than half a year as stock vehicles. For imported cars, due to the considerable time spent on transportation, customs clearance, and entry procedures, the timeframe is more lenient, typically classifying them as stock vehicles if they exceed six months to a year. Here are reasons why purchasing stock vehicles is not recommended: 1. After leaving the factory, various fluids, electronic components, batteries, rubber seals, and tires in new cars may deteriorate due to prolonged storage without periodic inspection and maintenance, leading to issues like moisture damage and aging. 2. Only a very few dealers perform periodic inspection and maintenance measures. While the cost isn't high, it consumes manpower and time. Some 4S stores even keep their inventory in open parking lots, exposing new cars directly to sun, wind, and rain. 3. For vehicles stored for too long, without proper warehouse management, the aging of electronic components and rubber products is hard to detect without professional equipment. Many long-stored vehicles also suffer from oil and power shortages.

What are the symptoms of a clogged expansion valve?

When an expansion valve becomes clogged, the air conditioning system may exhibit symptoms such as poor cooling performance, icing of the expansion valve, noisy compressor operation, and abnormal refrigeration. The expansion valve plays a throttling role in the air conditioning system. During operation, it regulates the refrigerant flow and system pressure by controlling the opening degree of the expansion valve to ensure normal system functioning. Causes of thermal expansion valve clogging: Clogging faults in the thermal expansion valve of the refrigeration system often occur, including "dirt clogging" and "ice clogging." The main cause of dirt clogging is the presence of impurities in the system, such as welding slag, copper chips, iron filings, fibers, etc. Ice clogging occurs due to excessive moisture (humidity) in the system. Sources of moisture include: (1) Insufficient vacuuming time during installation, failing to remove all moisture from the pipelines, and poor welding at pipeline connections, leading to air leaks. (2) Failure to purge the air from the connecting hoses when charging the system with refrigerant. (3) Introduction of air when adding lubricating oil to the system.

Can turning on the AC in a car provide heating?

Car air conditioning AC cannot provide heating because the AC button is the switch for the air conditioning compressor. In summer, when using the air conditioning, you need to press the AC button to turn on the cold air. The heating function in a car, on the other hand, utilizes the internal heat circulation of the car and does not require activating the air conditioning compressor. Here are some related details: 1. Car air conditioning is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions, providing a comfortable environment for passengers and reducing travel fatigue; it also creates good working conditions for the driver and plays an important role in ensuring safe driving as a ventilation device. 2. The heating in a car comes from the heat generated by the engine during operation. After the engine's cooling system dissipates heat from the engine, a fan directs this heat into the car cabin to create warm air; when the heating is not in use, the fan stops, the heating vents close, and the dissipated heat is completely released into the atmosphere. Therefore, car heating is a form of waste heat reuse and does not consume additional fuel.

What is the fuel tank capacity of the Jetta VS5?

The fuel tank capacity of the Jetta VS5 is 51 liters. It is a compact SUV under the FAW-Volkswagen Jetta brand. Among vehicles in the same class, the Haval M6 has a fuel tank capacity of 55 liters, and the Wuling Xingchen has a fuel tank capacity of 52 liters. If the owner wants to know the remaining fuel level, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it indicates that the fuel is almost empty, and when it is near F, it means the fuel level is sufficient. Maintenance of the fuel tank is as follows: Drain accumulated water and sediment from the fuel tank, and check for any fuel leakage at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and steam valves, also check if the vent holes are clear. The filter screen at the fuel filler inlet should remain intact to prevent impurities from entering the fuel tank during refueling, which could block the fuel lines. The sealing gasket on the fuel filler cap should also be intact to prevent fuel from spilling out while driving.

Will the Noise Increase After Applying Undercoating?

Applying undercoating will not increase the noise. Undercoating: Undercoating is a protective, rust-proof, and sound-insulating layer for the chassis. It is a high-tech adhesive rubber asphalt coating that is non-toxic, offers high coverage, and strong adhesion. It can be sprayed on exposed areas of the vehicle such as the chassis, wheel hubs, fuel tank, lower body panels, and trunk. After quick drying, it forms a durable elastic protective layer that prevents impacts from flying stones and gravel, as well as protects against moisture, acid rain, and salt corrosion on the metal parts of the chassis. This prevents rust and corrosion, ensuring the safety of the vehicle. Functions: Prevents gravel from striking the chassis, maintains the integrity of the vehicle's underbody, protects against corrosion, significantly blocks external heat, maintains interior temperature, and reduces fuel consumption. Application method for undercoating: Rinse the chassis with a high-pressure water gun, apply an engine degreaser to remove oil and dirt, blow out water from crevices with an air gun, dry with a towel, spray the rust-proof layer, perform localized touch-ups to ensure full coverage, remove surrounding masking materials, and clean non-target areas with a specialized cleaner.

Do the left-turn arrow and circular light turn green simultaneously?

Depending on road conditions, some left-turn arrows and circular lights in urban traffic systems turn green simultaneously. Urban Road Traffic: Urban roads prioritize user experience with a human-centered approach, emphasizing subjective comfort due to the economic development levels of different city areas and prominent road network hubs. They exhibit stronger humanistic elements, making them more user-friendly. Highways, however, focus more on technical aspects, prioritizing regional traffic efficiency. Except for administrative attributes influencing road network density and grade, highway networks are uniformly coordinated, better meeting the fundamental functional requirements of road engineering—ensuring unimpeded access to all necessary destinations. Traffic Light Design Principles: The simplest current method is timed control, where the activation and deactivation durations for each direction are preset. More complex systems use microcontroller or PLC programming, enabling different control strategies across time periods, synchronized or interlocked traffic signals for various directions, and adaptable control policies. The most advanced approaches involve adaptive control and intelligent transportation systems, now implemented in many major cities. These systems adjust signal timing dynamically based on real-time feedback from road sensors and cameras to optimize traffic flow.
