What are the symptoms of high engine temperature?

An excessively high engine temperature manifests in the following ways:1. When the engine temperature is too high, the intake air temperature also rises, resulting in reduced actual air intake volume. This decreases the engine's volumetric efficiency, leading to diminished power and torque output, which manifests as insufficient engine power.2. At excessively high temperatures, the combustion chamber reaches extremely high temperatures that can easily reach gasoline's ignition point, prematurely igniting the air-fuel mixture and causing engine knocking. This creates severe engine impact and vibration, subjecting components to additional shock loads that may cause premature failure.3. When overheated, pistons undergo excessive thermal expansion, reducing or even eliminating the clearance between pistons and cylinder walls. This increases piston movement resistance and may even cause scoring damage to both pistons and cylinder walls.

Should You Use Recirculation or Fresh Air Mode in Summer?

First use the fresh air mode or open the windows for ventilation, then switch to recirculation mode. In hot summers, many car owners habitually turn on the air conditioning's recirculation mode as soon as they enter the vehicle, thinking it will cool the cabin faster. However, this is incorrect because the interior temperature is higher than outside, making this approach less effective. More relevant information is as follows: 1. In summer, you can open doors on the same side or lower windows completely while keeping windows on the other side closed, then use the door opening/closing method to circulate and expel hot air from the cabin. 2. Open all four windows or diagonally opposite windows while driving to accelerate hot air circulation. When interior and exterior temperatures become similar, close the windows, turn on the AC cooling function, set the air circulation to fresh air mode, and adjust the temperature to the lowest setting to speed up cabin temperature stabilization.

Is it dangerous to drive on the highway with underinflated car tires?

Driving on the highway with underinflated car tires is dangerous. Effects of low tire pressure: Low tire pressure increases tire body deformation, making the tire sidewalls prone to cracking. It also causes flexing movements, leading to excessive heat buildup, accelerating rubber aging, fatigue of the cord ply, and cord breakage. Additionally, it increases the tire's contact area with the ground, accelerating shoulder wear. Effects of high tire pressure: Excessive tire pressure overextends the tire cords, reducing the tire body's elasticity. This increases the load on the car during driving, and impacts may cause internal cracks or blowouts. High pressure also accelerates tread wear and reduces puncture resistance.

Is It Safe to Sleep in a Car with the Air Conditioner and Windows Open?

Sleeping in a car with the air conditioner and windows open is a safe practice. When the car is stationary with the air conditioner running, the engine operates in an idle state, leading to incomplete fuel combustion, which generates carbon monoxide. This carbon monoxide can enter the car's interior through the air conditioning system. However, if there is air exchange with the outside, it will not pose a harm to the human body. The car's "internal circulation" and "external circulation" modes: Internal circulation means the air circulates within the car without any outside air entering. In this mode, external exhaust fumes and dust do not enter the car, and the air conditioning's cooling or heating efficiency is better. Internal circulation is suitable for use in traffic jams or polluted areas. External circulation, on the other hand, allows a small amount of outside air to enter while the air inside the car circulates. This helps replenish fresh air inside the car but may reduce the efficiency of the air conditioning's cooling or heating. External circulation is suitable when there are many passengers in the car or during long drives. Safe methods for sleeping in a car: Do not close the windows tightly; maintain good air circulation inside the car. Open the windows slightly while sleeping to prevent the risk of suffocation. Park the car in an outdoor area with ample space before sleeping, as small spaces may have poor air circulation, making it difficult to ensure fresh air inside the car. Check for any exhaust leaks, as car exhaust entering the interior can easily lead to poisoning.

Can new cars be registered during the National Day holiday?

New cars cannot be registered during the National Day holiday. The vehicle management office is closed on holidays. Methods for registering a new car: The process includes vehicle inspection, inspection review, acceptance, license plate selection, issuance of temporary license plates, and production of the vehicle license. The entire process takes approximately one morning. Notes for registering a new car: In the week following the National Day holiday, the number of vehicles coming for registration gradually increases. Currently, there are two peak periods for registration, around 10 AM and 2 PM. You can choose to register during off-peak hours. If the temporary license plate is still valid, you can also wait until after the peak period to register.

What to Do When the Seat Belt Buckle Gets Stuck?

There are several solutions if your car's seat belt buckle gets stuck: 1. If the buckle is stuck and cannot be pulled out, avoid using excessive force to yank it. Instead, gently pull and release it a few times, and the issue should resolve itself. 2. The buckle usually doesn't get damaged. If it keeps beeping or stops functioning, first check if there's any debris blocking the slot. You can try repeatedly pressing the release button or use non-sharp tools like toothpicks to clean it. These methods can generally fix common issues. If the problem persists, it's best to take it to a 4S shop for inspection and repair.
