What is catchpower tire?

catchpower is not actually a tire brand, but an economical tire under the windforce WANTUCHE brand. The parent company of WANTUCHE tires is Qingdao Windforce Tire Co., Ltd. Windforce tires are mainly for export, while WANTUCHE is a new brand specifically established by Windforce Tire for the domestic market. The WANTUCHE catchpower series tires have good wear resistance and comfort, and the four drainage grooves can provide the vehicle with good driving stability and drainage performance. Tire maintenance precautions: If the tire pressure is too low, the deformation of both sides of the tire increases, the tire contact area widens, the tread arches inward, the shoulder load intensifies, and the pressure in the middle part decreases, forming a bridge effect, which causes uneven tread wear and abnormal wear in the form of sawtooth or wave patterns. If the remaining groove depth of the tire tread reaches or falls below 1.6 millimeters, the tire must be replaced because the tire's drainage capacity has significantly decreased at this point, reducing the friction between the vehicle and the ground, making driving more dangerous.

What does the anti-lock braking system mean?

Anti-lock braking system, abbreviated as ABS, stands for Anti-lock Braking System or Anti-skid Braking System in English. This system automatically adjusts the braking force on the wheels during braking to prevent wheel lock-up and achieve optimal braking performance. Below are detailed explanations: 1. Working Principle: The anti-lock braking system automatically controls the magnitude of the braking force during vehicle braking, ensuring that the wheels do not lock up and maintain a state of rolling and sliding (with a slip ratio of about 20%), thereby maximizing the adhesion between the wheels and the ground. ABS controls the pressure in the brake lines acting on the wheel brake cylinders, preventing the wheels from locking up during emergency braking, thus maintaining good directional stability of the vehicle even under hard braking. 2. Advantages: In vehicles not equipped with ABS, braking on snowy surfaces can easily cause the vehicle to lose directional stability; meanwhile, the driver must use a hydraulic modulator (also known as an actuator) to stop the vehicle. Conversely, in vehicles equipped with ABS, the system automatically sends control commands to the hydraulic modulator, enabling faster, more accurate, and more effective braking control.

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.
