What Causes Headlight Yellowing?

Headlight yellowing occurs due to prolonged exposure to air, high temperatures, ultraviolet rays, and oxidation, leading to aging of the headlight cover, resulting in yellowing and cracking. Here are some precautions for car headlight maintenance: 1. Replacement: Ensure the car headlights maintain good sealing, especially to prevent contamination and damage to the reflector coating. When replacing bulbs and diffuser glass, avoid touching the lens with fingers to prevent leaving sweat or oil marks that may cause the reflector to lose its luster and reduce reflection efficiency. 2. Regular Inspection: Periodically check and adjust the headlight beams to ensure the headlight's illumination distance meets requirements, with consistent upper and lower beams. The diffuser glass should be correctly installed as specified to prevent loosening or displacement, maintaining vertical prisms.

What are the components of an automotive air conditioning system?

The following is an introduction to the automotive air conditioning system: Modern air conditioning systems consist of a refrigeration system, heating system, ventilation and air purification devices, and a control system. 1. Ventilation system: Its function is to ensure indoor ventilation while the car is in motion, continuously introducing fresh air into the car interior and expelling air mixed with dust, carbon dioxide, and harmful gases from the engine. 2. Heating system: Its function is to heat the air inside the car or fresh air entering from outside, achieving the purposes of warming and dehumidifying. 3. Refrigeration system: Its function is to lower the temperature inside the car when the external environment temperature is high, making passengers feel cool and comfortable. 4. Air purification system: Its function is to filter the introduced air, continuously removing polluted gases from the car interior to maintain clean air inside. 5. Control system: The control system mainly consists of electrical components, vacuum pipelines, and operating mechanisms.

What is the normal range for tire pressure monitoring data?

Standard tire pressure monitoring data is considered normal within the range of 2.4-2.5 bar; for reinforced tires, the normal range is 2.8-2.9 bar. Abnormal tire pressure generally occurs due to the following three reasons: Abnormal tire pressure: Typically, an alarm will trigger if the pressure is below 1.8 bar or exceeds 3.0 bar. In such cases, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the system will continue to display the previously recorded data, causing the tire pressure monitoring indicator to light up. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, it can also cause the tire pressure warning light to illuminate. In case of sensor damage, the only solution is to replace it with a new component.

Can I Pick Up the Car on the Same Day When Paying in Full?

The possibility of picking up the car on the same day when paying in full is not very high. Here is some relevant information about buying a car with full payment versus financing: 1. Convenience of Full Payment: Starting from July 1st, in addition to the price of the car itself, buyers will need to pay other fees, including vehicle and vessel tax, insurance, compulsory traffic insurance, etc. Some people find other purchasing methods more complicated, such as applying for loans, handling purchase tax, and license plate registration. By choosing financing or leasing, buyers receive a new car with complete documentation, insurance, and taxes already taken care of. The subsequent expenses mainly consist of vehicle purchase tax and insurance fees, which account for the largest portion. 2. Stability of Financing a Car: When buying a car, it's inevitable to encounter various service fees, insurance costs, and expenses related to maintenance, decoration, etc. For those who choose to finance their car, completing all the above processes means the job is done.

How to Adjust the Carburetor Air-Fuel Mixture to Optimal on a Scooter?

Scooter carburetor air-fuel mixture can be adjusted to optimal as follows: Turn the mixture screw clockwise until it bottoms out, then turn it counterclockwise one and a half turns. Below is relevant information about carburetors: 1. Definition: A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine's operation. 2. Working Principle: A carburetor is essentially a tube with an adjustable plate called a throttle valve in the middle to control the airflow through the tube. There is a constricted section in the tube called a venturi, where a vacuum is created. This constricted section has a hole through which fuel is drawn by the vacuum.

What is the New Energy Vehicle Subsidy Program?

Here is a detailed introduction to the new energy vehicle subsidy program: 1. Annual reduction: From the subsidy standards, there is a year-by-year reduction from 2020 to 2022. The subsidy phase-out intensity and pace are moderated, with the subsidy standards in principle decreasing by 10%, 20%, and 30% respectively from the previous year during 2020-2022. 2. Subsidy regulations: Pure electric passenger vehicles with a range below 300 kilometers receive no subsidy; those with a range of 300-400 kilometers (including 300 kilometers) see a reduced subsidy; those with a range above 400 kilometers (including 400 kilometers) also see a reduced subsidy. For vehicles in urban public transport, road passenger transport, taxi (including ride-hailing), sanitation, urban logistics distribution, postal and express delivery, civil aviation airports, and government agency official use that meet the requirements, the subsidy standard is reduced by 10% from the 2020 level.
