During the annual inspection of vehicles, the requirements for tires are that the same model, specification, and tread pattern should be installed on both sides of the same axle. The tire bolts and axle bolts should be complete and tightened; the tire specifications should match the motor vehicle product announcement and the motor vehicle factory certificate; the length of the tire tread and sidewall should not exceed 25mm or be too deep, as this can affect abnormal wear and deformation. Depending on the type and usage of the vehicle, dedicated school buses should use tubeless radial tires; highway buses, tourist buses, and school buses should have all wheels fitted with retreaded tires and should be sent for regular inspections; vehicles transporting dangerous goods and other buses with a length greater than 9m should use radial tires; for passenger cars, motorcycles, and trailers, the tread depth should be greater than or equal to 1.6mm, while the tread depth of the steering tires for other motor vehicles should be greater than or equal to 3.2mm; the tread depth of the remaining tires should be greater than or equal to 1.6mm. Tire maintenance methods: regularly clean stones from the tire treads; minimize exposure of tires to direct sunlight; promptly check tire pressure; pay attention to suspension maintenance; inspect front wheel alignment; be mindful of driving habits, choosing smooth roads to avoid objects that can puncture or scratch tires, and avoid chemical spills that can corrode tires. Steps for vehicle annual inspection: exhaust emission test, the first item in the annual inspection, which requires re-inspection if failed; violation check, if there are unresolved violations, the inspection cannot be passed; appearance inspection, mainly checking for damage to the vehicle body, tires, lamp covers, etc., and whether the owner has made unauthorized modifications to the vehicle; on-site testing, mainly checking brakes, lights, horn, chassis, etc.; review, after all tests are completed, the vehicle management office will review the indicators; certification, if the review is passed, the motor vehicle inspection certificate can be obtained.

What is the lowest temperature that a car air conditioner can be set to?

Introduction to the lowest temperature setting of a car air conditioner: Generally speaking, the lowest temperature inside a car with air conditioning is around 10 degrees Celsius, and it also depends on the effectiveness of the car air conditioner refrigerant. However, the cooling limit for most car air conditioner refrigerants is 10 degrees. Below is an introduction to car air conditioner maintenance: 1. Do not arbitrarily adjust the air conditioner vent direction: When using the air conditioner, not paying attention to adjusting the direction of the air flow can hinder its effectiveness. Based on the principle that cold air sinks and hot air rises, the correct approach is to direct the vents upward when cooling and downward when heating. 2. Regularly start the air conditioner in winter: In some regions where winters are relatively mild, some car owners do not use the air conditioner at all during the winter. Prolonged disuse can cause the rubber seals to age, and the lubricating oil on the internal components of the air conditioner can dry out. Regularly starting the air conditioner allows the components to be lubricated, maintaining good condition. Therefore, it is best to start the air conditioner at least once a week during winter. 3. Avoid using the air conditioner for too long each time: Some drivers keep the air conditioner running continuously after entering the car. Prolonged use can increase the pressure on the condenser, causing wear and tear on the cooling system. Therefore, it is advisable not to use the air conditioner for too long each time. If the interior temperature has reached a comfortable level, the air conditioner can be turned off and restarted after a while. 4. Ventilate and cool down before driving in summer, then switch to internal circulation: In hot summers, many drivers habitually turn on the internal circulation of the air conditioner as soon as they enter the car, thinking it will cool the interior faster. However, since the interior temperature is higher than the outside temperature, this method is ineffective. Upon entering the car, it is better to first open the windows for ventilation and turn on the external circulation to expel the hot air. Once the interior temperature has dropped, switch to internal circulation.

Should You Leave a Small Gap in the Car Window When Parking for a Long Time?

When parking for a long time, it is best not to leave a gap in the car window, as it may attract thieves and lead to theft of items inside the vehicle. Here are the reasons for leaving a gap in the window: 1. Lowering the interior temperature: Studies show that if the window is left open while the car is parked outdoors under direct sunlight, the temperature inside can be reduced by up to 20-30 degrees Celsius compared to a completely sealed interior. Leaving a small gap in the window can effectively lower the temperature inside the car. 2. Reducing interior odors: Many cars have strong interior odors, especially when exposed to sunlight. Under high temperatures, the leather and interior joints release large amounts of harmful gases, including formaldehyde and benzene. If the windows are closed, entering the car will expose you to these odors immediately. However, leaving a gap in the window to maintain air circulation can effectively alleviate this issue.

What Causes High Engine Idle Speed?

High idle speed is mainly caused by the following reasons: 1. The idle switch fails to close; 2. Malfunction of the idle control valve; 3. Air intake pipe leakage; 4. Incorrect valve timing; 5. Fuel injector dripping or clogging; 6. Exhaust system blockage; 7. EGR valve opening during idle operation. Below are the solutions for high idle speed: 1. Adjust or replace the throttle position sensor; 2. Clean or replace the idle control valve and perform basic idle speed setting with a dedicated decoder; 3. Locate the leakage point and reseal or replace related components; 4. Check timing marks and readjust valve timing according to standards; 5. Clean and inspect each fuel injector's spray volume to ensure no clogging or dripping; 6. Replace the three-way catalytic converter; 7. Remove carbon deposits from the EGR valve or replace the EGR valve.

How Much Refrigerant Should Be Added to a Car's Air Conditioning System?

Introduction to Adding Refrigerant to Car Air Conditioning: The amount of refrigerant to be added to a car's air conditioning system is generally around 2-3 cans, with most models requiring between 450-650 grams. The exact amount may vary depending on the vehicle model and the content of the canned refrigerant. In practice, it is essential to follow the manufacturer's instructions in the user manual or rely on the actual pressure readings from the air conditioning pressure gauge. Phenomena and Hazards of Overfilling Refrigerant in a Car: 1. Excessive refrigerant can cause unstable idling, belt slippage, and noise. 2. The pressure relief valve may automatically open and release excess gas. 3. In high-end vehicles, the high-pressure protection compressor may stop working, which can severely lead to the rupture of high-pressure pipes. 4. If the internal refrigerant is insufficient, the internal pressure will be too low, reducing the amount of heat removed during the compression and release process. The air conditioning system will not achieve the desired cooling effect.

Can a small car be equipped with a parking air conditioner?

Can a small car be equipped with a parking air conditioner? The following is a related introduction to parking air conditioners: 1. Introduction: A parking air conditioner is an in-vehicle air conditioner. It refers to a device that uses the vehicle's DC power supply (12V/24V/36V) to allow the air conditioner to operate continuously when parking, waiting, or resting, regulating and controlling the temperature, humidity, airflow, and other parameters of the in-cabin air environment, fully meeting the comfort and cooling needs of truck drivers. 2. System Composition: Due to the limitations of the vehicle's battery capacity and poor user experience in heating during winter, parking air conditioners are mainly single-cooling type. They generally include a refrigerant medium delivery system, cooling source equipment, terminal devices, and other auxiliary systems. The main components include: condenser, evaporator, electronic control system, compressor, fan, and piping system. The terminal devices utilize the distributed cooling capacity to specifically adjust the air conditions inside the cabin, providing truck drivers with a comfortable resting environment.

Can Parking Lot Scratches Be Covered by Insurance?

Yes, it can be covered by insurance. If the car owner has purchased the additional coverage "Third Party Not Found Special Clause" under the car damage insurance, the insurance company will cover the full cost. If the incident occurs in a free parking lot, the parking lot will only be liable for compensation if there is intentional or gross negligence in vehicle storage damage; general scratches do not require them to take responsibility. After the incident, report the case within 48 hours, obtain an accident confirmation form from the traffic police, and then contact the insurance company for claims. Here is supplementary information about vehicle insurance: Vehicle insurance, also known as motor vehicle insurance or auto insurance, refers to a type of commercial insurance that covers personal injury or property damage caused by natural disasters or accidents involving motor vehicles. Auto insurance is a type of property insurance. In the field of property insurance, auto insurance is a relatively young category, as it emerged and developed alongside the appearance and popularization of automobiles. Additionally, unlike modern motor vehicle insurance, early auto insurance primarily focused on third-party liability as the main coverage and gradually expanded to include risks such as collision damage to the vehicle body.
