What does AC in air conditioning mean?

The AC button on the air conditioner is the abbreviation for Air-conditioning. Pressing the AC button starts the air conditioning to adjust the temperature according to the set value, while turning it off only activates the air blower. Here are specific details about AC in air conditioning: 1. AC can be understood as the compressor switch key. In cars, it indicates cooling. When AC is lit, it means the compressor is working, and the engine needs to provide power, which is why using air conditioning in summer increases fuel consumption. 2. In winter, the heat generated by the engine is used to raise the temperature inside the car. The engine coolant is connected to the heater core inside the air conditioning assembly, and the blower blows air through the heater core fins to produce hot air for heating the car interior. Therefore, using air conditioning in winter does not increase fuel consumption, and since AC is used for cooling and temperature adjustment, turning on AC in winter does not increase the power of the heater.

Can You Die from Sleeping in a Car with the AC On?

If you spend the night in the car, it is certainly possible. Turning on the AC usually involves closing the windows, and running the AC requires the engine to be on. The engine's combustion inevitably produces carbon monoxide. When the windows are tightly closed, the concentration of carbon monoxide inside the car will gradually increase until it reaches lethal levels, leading to poisoning and death. Function of the AC: The car air conditioning system is designed to regulate and control the temperature, humidity, air cleanliness, and airflow inside the vehicle to optimal levels. It provides a comfortable environment for passengers, reducing travel fatigue, and creates favorable working conditions for the driver. It serves as a crucial ventilation device for ensuring safe driving. Precautions: For your own safety and that of your family, try to avoid sleeping in the car. If you must sleep in the car, park it in a well-ventilated area to allow the wind to disperse any toxic gases around the vehicle. Do not close the windows completely—leave them slightly open to ensure proper air circulation and sufficient oxygen inside the car while maintaining some privacy.

How many points will be deducted for not meeting vehicles according to regulations while driving?

Generally, 1 point will be deducted for not meeting vehicles according to regulations while driving. When driving, special attention should be paid to roads without centerlines, narrow roads, and narrow bridges. It is necessary to slow down and pass on the right side while ensuring the safety of non-motor vehicles and pedestrians. When encountering difficulties in meeting vehicles, the party with the right-of-way condition should yield first. Principles of yielding when meeting vehicles: The principle of yielding when meeting vehicles is that turning motor vehicles should yield to straight-going vehicles, vehicles from the right side have priority, and right-turning vehicles should yield to left-turning vehicles. Relevant regulations on yielding when meeting vehicles: Vehicles with traffic signs or markings indicating priority should pass first; at intersections without traffic signs or markings, vehicles should stop and observe before entering, yielding to vehicles from the right side; turning motor vehicles should yield to straight-going vehicles; right-turning motor vehicles traveling in opposite directions should yield to left-turning vehicles.

How to Go to the DMV Without a Temporary License Plate?

The only correct approach is to use a tow truck to transport the vehicle that needs to be registered to the DMV for license plate issuance. According to the "Road Traffic Safety Law," driving a motor vehicle without displaying a license plate is considered a violation of traffic regulations. If caught by traffic police, the penalty includes a deduction of 12 points. Below are specific details about license plates: 1. Function of License Plates: License plates serve as a numbering and information registration system for vehicles. Their primary purpose is to identify the vehicle's region of registration and to trace the owner and registration details. 2. Classification by License Plate Colors: Large civilian vehicles have yellow plates with black characters. Small civilian vehicles have blue plates with white characters. Embassy vehicles for foreigners have black plates with white characters and a red "Embassy" character mark. Consulate vehicles for foreigners have black plates with white characters and a red "Consulate" character mark. Other foreign vehicles have black plates with white characters. Test vehicles have blue plates with white characters and a "Test" character mark before the numbers. Learner vehicles have blue plates with white characters and a "Learner" character mark before the numbers.

Will Tire Pressure Decrease in Cold Weather?

Cold weather can cause tire pressure to drop. When temperatures decrease, it's advisable to slightly increase tire pressure to prevent abnormal tire heating. However, tire pressure should not be excessively high as it may reduce traction and affect driving comfort. Tire pressure is crucial for road safety and is a dynamic value rather than a constant one. It's recommended to check tire pressure at least once a month. Additionally, tire pressure should be adjusted with each seasonal change. Tire Pressure: During winter, tire rubber hardens and becomes relatively brittle, with reduced friction coefficients. This requires maintaining tire pressure that's neither too high nor too low. In cold temperatures, excessively low pressure can accelerate aging in soft tires and increase ground contact, leading to faster wear and reduced tire lifespan. Therefore, proper tire maintenance is essential. Tire Replacement: Consider switching to better winter tires. Due to cold weather, tire rubber hardens compared to summer conditions. Even though many vehicles come with all-season tires, icy and slippery roads challenge tire traction. For driving safety, switching to winter tires is highly recommended.

Can Vehicle Inspection Be Conducted During National Day?

Generally, vehicle annual inspections cannot be conducted during National Day in most areas. However, some regions may offer inspection services during the holiday to alleviate inconvenience for working individuals. It is advisable to consult the local vehicle management office for specific arrangements. You will need to visit the local vehicle management office and the designated inspection center for both physical and online vehicle checks. There are many important considerations for vehicle annual inspections. Inspection Schedule: For the first six years, vehicles must undergo inspection every two years. After six years, inspections are required annually. The inspection month is based on the registration month indicated on the vehicle's license. The first step in the inspection process is the exhaust emission test, which monitors engine exhaust emissions and helps determine if the engine is functioning optimally, including fuel efficiency. Exterior Appearance: Avoid excessive customization of the vehicle's exterior, as it may lead to inspection failure. Unnecessary modifications not only incur additional costs but also risk failing the inspection. Additionally, unauthorized changes to the vehicle's body or engine are strictly prohibited. Purchasing vehicles of unclear origin is strongly discouraged, as it may result in legal consequences.
