Is It Safe to Sleep in a Car with the Air Conditioning On in Summer?

Sleeping in a car with the air conditioning on in summer is not safe. According to experimental data, in a closed car, running the air conditioning produces a large amount of carbon monoxide. In just over 20 minutes, the carbon monoxide concentration can exceed safe levels significantly, causing a noticeable sense of suffocation. Regardless of the type of car or whether the air circulation is set to internal or external, carbon monoxide can still enter the cabin. Precautions for using air conditioning: 1. Use external circulation after sun exposure: If the car has been exposed to the sun outdoors, first turn on the external circulation to ventilate and dissipate heat. Additionally, opening the windows and sunroof can speed up heat dissipation. After 3-5 minutes, when the interior temperature has stabilized, close the windows, turn on the cooling, and switch the air circulation to internal. 2. Use internal circulation in cold weather: In cold weather, wait a moment after getting in the car until the engine reaches normal operating temperature. Then, turning on the heater with internal circulation can quickly raise the temperature. 3. Use external circulation on highways: During high-speed driving, you can turn on the external circulation as needed. Prolonged use of internal circulation during long drives can lead to stale air inside the car, so switching to external circulation helps maintain a comfortable temperature while bringing in fresh air. However, if the air conditioning was initially turned on to cool the car, avoid keeping the external circulation on continuously. Instead, periodically switch to external circulation to refresh the air.

What is the average fuel consumption of the old Excelle?

The average fuel consumption of the old Excelle is 9.0. Here are the pros and cons of the Excelle car: 1. Pros: Good sound insulation, very sensitive steering wheel, strong engine power during high-speed driving, and stable acceleration. The exterior is very stylish, and the paintwork is also attractive. The interior resembles that of a mid-range car, not complicated and very practical. The sound system of this car is also of good quality, and the air conditioning works well. 2. Cons: The engine noise is relatively loud. The pedals are too high, which can cause fatigue for the driver after long periods of driving. The gear shift is not very comfortable to use, and the horn button is small and hard. The passenger side window glass often does not rise fully.

What is the optimal remaining battery level for charging new energy vehicles?

New energy vehicles have an optimal charging range between 20% and 90% battery level. Charging within this range can effectively minimize the impact on the power battery and significantly extend its service life. There are two main categories of new energy vehicles: 1. Hybrid Electric Vehicles (HEVs): These vehicles use traditional fuels while being equipped with both an electric motor and an internal combustion engine to enhance low-speed power output and reduce fuel consumption. Based on whether they can be externally charged, they can be further classified into Plug-in Hybrid Electric Vehicles (PHEVs) and Mild Hybrid Electric Vehicles (MHEVs). 2. Battery Electric Vehicles (BEVs): As the name suggests, these vehicles are primarily powered by electricity. Most BEVs directly use electric motors for propulsion, with some models mounting the motor in the engine compartment, while others integrate four motors directly into the wheels (using the wheels as rotors). The main challenge lies in electricity storage technology.

How to Add Car Coolant? Where to Add It?

Car coolant is added to the radiator in the engine compartment. The coolant should be filled between the MAX and MIN level marks. There are two main reasons for coolant alarms: 1. Coolant loss: For example, if the vehicle is parked overnight and a coolant alarm appears when starting the next morning, check for any traces of antifreeze under the vehicle chassis. If present, it indicates a leak in the cooling system that requires repair. If there is no leak, simply replenishing the antifreeze will resolve the issue. 2. Water temperature alarm: If a coolant alarm suddenly appears during high-speed driving, accompanied by a water temperature alarm, it suggests a problem with the engine cooling system. Issues such as damaged water pump impellers preventing proper coolant circulation, malfunctioning cooling fans, or clogged radiator/condenser surfaces impairing heat dissipation can all trigger the coolant warning light.

Is It Necessary to Buy a Car Cover for a New Car?

If the owner parks the vehicle on the roadside for a long time or in open parking areas with high uncertainty, such as residential areas, purchasing and using a car cover is highly recommended. Otherwise, there is no need to buy one. Car maintenance tips: 1. Engine cleaning: The car engine should be cleaned at appropriate intervals. Prolonged use can lead to the formation of a thick layer of carbon deposits on the engine surface, which can significantly corrode the rubber components inside the engine. 2. Regular checks: During summer, temperatures are generally higher, causing gasoline and water to evaporate more easily than usual. Therefore, it is essential to frequently check the radiator and fuel tank, topping them up promptly when levels are low.

What are the reasons for high pressure on both sides of a car's air conditioning system?

Car air conditioning system experiencing high pressure on both sides can be caused by air in the system; system blockage or malfunction. The functions of an air conditioning filter include the following 3 points: 1. Providing fresh air: Prevents car windows from fogging up, ensuring clear visibility for the driver and safe driving; supplies fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety; effectively sterilizes and deodorizes. 2. Ensuring safety and hygiene: Maintains clean air in the cabin, preventing bacterial growth; effectively separates solid impurities such as dust, powder, and grinding particles from the air; efficiently blocks pollen, ensuring that drivers and passengers do not experience allergic reactions that could affect driving safety. 3. Adsorbing harmful substances: Adsorbs moisture, soot, ozone, and odors from the air, with strong and long-lasting moisture adsorption capabilities.
