How to Check the Tire Safety Line?

The method to check the tire safety line is: 1. Find the raised horizontal bar between the two tread patterns of the tire; 2. Observe whether the tread is flush with the raised bar. The functions of tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit the torque of traction and braking, ensuring the adhesion between the wheels and the road surface; 3. To reduce and absorb the vibrations and impact forces during driving, preventing severe vibrations and early damage to car components. The maintenance methods for tires are: 1. Regularly clean the stones in the tire gaps; 2. Reduce exposure of tires to sunlight; 3. Promptly check the tire pressure; 4. Pay attention to the maintenance of the suspension; 5. Regularly inspect the front wheel alignment.

How to Check the Production Date of Tires and Vehicles?

Tire and vehicle production dates can be checked by: 1. Locating a set of numbers on the tire sidewall—the first two digits represent the week of production in the year, and the last two digits represent the year of production; 2. Checking the nameplate below the B-pillar on the passenger side, inspecting the new vehicle’s certificate of conformity (production date is located in the upper right corner), or looking for a paper nameplate on the windshield in front of the driver’s seat. Tire maintenance methods include: 1. Regularly removing stones stuck in tire treads; 2. Minimizing exposure to direct sunlight; 3. Frequently checking tire pressure; 4. Paying attention to suspension maintenance; 5. Periodically inspecting front wheel alignment; 6. Being mindful of driving habits.

What are the symptoms of a faulty automatic transmission computer?

Introduction to the symptoms of a faulty automatic transmission computer: In addition to difficulty in shifting gears, gear slipping, and gear locking, it can also cause the mixture to be too lean or too rich. A too lean mixture can result in difficulty starting, weak driving, engine backfiring, etc., while a too rich mixture can increase fuel consumption, incomplete combustion, and severe carbon buildup in the cylinders and spark plugs. The specific symptoms of a faulty automatic transmission computer are as follows: 1. Difficulty in shifting gears: This mainly applies to manual transmission vehicles. Some drivers usually prefer to press the brake and clutch pedals simultaneously before shifting. If the driver finds it impossible to shift after pressing the clutch when shifting into first gear, whether shifting up or down, this indicates a problem with the transmission. Possible causes include insufficient or low-viscosity transmission fluid and issues with clutch linkage. 2. Gear slipping: In a normally functioning transmission, when the car is stationary, the transmission gear should remain in the designated gear or the gear specified by the computer to maintain a certain RPM range until the computer initiates a gear shift. However, if the transmission gears slip automatically, the car can spontaneously jump out of the drive gear into neutral. 3. Gear locking: This means entering protection mode. The computer can detect faults in the transmission. The more advanced the car, the stronger the computer's detection capability. In such cases, the computer will lock the transmission in third or fourth gear to alert the driver to seek immediate repair. 4. Transmission damage: The secondary oxygen sensor will fail to provide accurate data to the car's computer, leading to a mixture that is either too lean or too rich. A too lean mixture can cause difficulty starting, weak driving, and engine backfiring, while a too rich mixture can increase fuel consumption, incomplete combustion, and severe carbon buildup in the cylinders and spark plugs. When this fault occurs, the engine warning light should illuminate. Once detected, it is recommended that the driver promptly visit a 4S shop for inspection and repair.

How to Identify Stock Vehicles When Buying a Car?

Methods to identify stock vehicles when buying a car are: 1. Check the vehicle nameplate on the B-pillar; 2. There is also a vehicle nameplate in the engine compartment, which indicates the production date of the car. The vehicle nameplate is a sign that displays the basic characteristics of the vehicle, including the manufacturer, model, engine power, total weight, load capacity or passenger capacity, factory number, production date, and manufacturer name. Precautions when inspecting a new car include: checking the factory nameplate to ensure the vehicle's displacement and production date, and then looking for signs of tampering or scratches on the nameplate. If it has been tampered with, extra caution is needed. A stock vehicle refers to a car that has not been sold for more than six months.

What is the difference between National 5 and National 6 emission standards?

The differences between National 5 and National 6 emission standards are: 1. Different emission levels: The carbon monoxide emission limit for National 5 is 1000mg per kilometer; for National 6 it is 700mg per kilometer. 2. Different restrictions: The sulfur content limit for National 5 is 10ppm, and the manganese content limit is 2mg per liter; for National 6, the sulfur content limit is 5ppm, and the manganese content limit is 1mg per liter. 3. Different forms: During the National 5 phase, diesel and gasoline vehicles had different emission standards; National 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type used.

How to Determine if a Car Compressor is Good or Bad?

To determine if a car compressor is good or bad, follow these steps: 1. Start the engine and maintain the speed between 1250 to 1500 RPM; 2. Connect the manifold pressure gauge to the air conditioning refrigeration system, turn on the AC switch, and set the fan to the maximum position; 3. Touch the compressor's intake and exhaust ports. A good compressor will have a cold intake and a hot exhaust with a significant temperature difference between them. If not, it is likely damaged. The working principle of a car compressor: It draws refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the radiator, and the refrigerant changes from a gaseous to a liquid state, increasing its pressure.
