Why Do Inventory Cars Exist?

Normally, some manufacturers produce models with special configurations or colors that cannot find suitable buyers, and over time, these become backlogged "inventory cars." There may also be other reasons. Additionally, some backlogged "inventory cars" might remain unsold due to quality issues, so caution is advised when selecting them. Generally, if a car has been in inventory for over three months or half a year, it can be classified as an inventory car. The main reasons not to buy an inventory car are: 1. After leaving the factory, various fluids, electronic components, batteries, rubber seals, and tires in a new car may deteriorate due to prolonged storage without periodic inspection and maintenance, leading to issues like moisture damage and aging. 2. Only a very few dealerships perform periodic inspection and maintenance measures. While the cost is not high, it consumes manpower and time. Some 4S stores even keep their inventory cars in open parking lots, exposing them directly to sunlight, wind, and rain. 3. For inventory cars stored for too long, without proper warehousing management, the aging of electronic components and rubber parts is often undetectable without professional testing equipment. Many long-term inventory cars also suffer from insufficient oil or battery charge.

What are the general functions of engine oil?

Engine oil filter is the abbreviation of engine oil filter, and its main functions are as follows: 1. Filter the engine oil inside the engine to improve its cleanliness and lubricity. 2. Supply clean engine oil to the crankshaft, connecting rod, camshaft, turbocharger, piston ring, etc., to provide lubrication, cooling, and cleaning effects, thereby reducing engine wear, enabling it to perform at its best, and extending the lifespan of these components. The following is related content introduction: Experts recommend replacing the oil filter every time the engine oil is changed. The reason is that the contaminants in the old oil filter can reduce the viscosity and cleanliness of the new engine oil, affect the oil circulation speed, and also damage the engine.

How to Quickly Remove Odors from a New Car?

To remove odors from a new car, you can place some orange or tangerine peels inside the car, as well as some activated charcoal. Additionally, it's important to frequently open the windows for ventilation, which can quickly eliminate the odors inside the car. More methods for removing odors from the car are as follows: 1. Place activated charcoal in the car: Put several large bags of activated charcoal both in the front and back of the car to effectively absorb odors. However, every once in a while, place the bamboo charcoal bags under direct sunlight for more than 2-3 hours to refresh them. 2. If you drive for long periods, you can purchase an air purifier. During hazy or windy weather, turn on the recirculation mode along with the air purifier to block out some external pollutants. 3. Use the air conditioning to remove odors. If opening the windows is not an option, use the air conditioning's external circulation mode to maintain airflow inside the car. Regularly clean the air conditioning system, as it can accumulate harmful gases over time.

How to Distinguish Between China 5 and China 6 Vehicles?

China 5 emission standard is marked with a V, while China 6 emission standard is marked with a Ⅵ, both using Roman numerals. There are four methods to check the emission standard: 1. Check the vehicle's environmental protection label on the windshield; 2. Log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire, or bring the vehicle registration certificate to the vehicle management office for inquiry; 3. Refer to the vehicle's factory certificate for details; 4. Estimate based on the year of vehicle registration: most vehicles registered after 2008 are China 4, while those registered in 2007 could be either China 3 or China 4, and so on.

What causes unstable charging current?

The reasons for unstable charging current include the following: 1. The generator belt is too loose. Check if the tightness of the generator belt is appropriate, and replace or adjust it. Inspect the engine belt tensioner and replace it if necessary. 2. Poor connection between the generator and the battery. Check the wiring connections between the generator and the battery terminals. Use a test light to inspect the engine and ensure it runs stably. 3. Uneven wear of the carbon brushes or failure of the carbon brush springs. 4. Burned or contaminated contacts in the voltage regulator. 5. The regulator adjustment does not meet the requirements.

What does the ESC button in a car mean?

ESC stands for Electronic Stability Control system, also known as the Driving Safety Supplement System. It is an active safety device in vehicle configurations, an abbreviation for Electronic-Stability-Controller. Pressing and holding this button can turn the electronic stability control system on or off, but it is recommended not to turn it off when driving on highways, as it poses significant safety risks. ESC is an active safety technology that assists drivers in controlling the vehicle. It is an extension of the Anti-lock Braking System (ABS) and Traction Control System (TCS) functions. Additionally, it incorporates a yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor when the vehicle is steering. The Electronic Control Unit (ECU) controls the driving and braking forces of the front, rear, left, and right wheels to ensure the vehicle's lateral stability during driving. When the vehicle is extremely unstable (e.g., during sharp turns or lane changes), ESC compensates for the vehicle's stability by applying the wheel brakes or controlling engine torque, correcting the vehicle's instability to help prevent accidents. The system consists of three main components: sensors, the Electronic Control Unit (ECU), and actuators. The ECU monitors the vehicle's operational status and intervenes in the engine and braking system. A typical ESC system includes sensors such as four wheel speed sensors, a steering wheel angle sensor, a lateral acceleration sensor, a yaw rate sensor, and a brake master cylinder pressure sensor. The actuation part includes the traditional braking system (vacuum booster, pipelines, and brakes) and hydraulic regulators. The ECU works in conjunction with the engine management system to intervene and adjust the engine's power output. The system collaborates with the engine ECU. When the drive wheels slip, the electronic system compares the speeds of each wheel to determine if the drive wheels are slipping. It then automatically reduces the throttle intake, lowers the engine speed, and decreases power output to brake the slipping drive wheels. This reduces slippage and maintains the optimal power output for tire grip on the road, preventing the drive wheels from slipping regardless of throttle input. There are many active safety systems in cars similar to the Electronic Stability Control system, such as the ABS Anti-lock Braking System and the EBD Brake Force Distribution System. The ABS system is almost a standard feature in every car, preventing wheel lock-up during emergency braking. If the wheels lock up during emergency braking, the driver cannot control the vehicle's trajectory or decelerate the car. Locked wheels cannot provide traction, leaving the car in an uncontrolled state, which is highly dangerous. To prevent wheel lock-up during emergency braking, engineers developed the ABS Anti-lock Braking System.
