Using air conditioning in summer does consume more fuel. Here is more information about car air conditioning systems: Classification of Car Air Conditioning: Generally, based on vehicle configurations, car air conditioning systems are mainly divided into manual air conditioning and automatic air conditioning. Adjusting the fan speed has no relation to the compressor. Once the air conditioning is turned on for cooling, the compressor operates at full speed continuously, so there is no concept of fuel-saving or not. As for adjusting the temperature in manual air conditioning, it merely mixes varying amounts of hot air with the cold air. In practical use, the interior temperature rarely reaches conditions that would allow the compressor to stop running. Simply put, this type of non-variable compressor runs at full speed continuously once activated and does not shut off, meaning even if the temperature is set higher, it will not save fuel. Differences in Car Air Conditioning: Typically, manual air conditioning systems are equipped with non-variable compressors. Automatic air conditioning systems can also use non-variable compressors, operating on the same principle as manual systems but with the addition of an automatic thermostat. This device can detect the difference between the interior temperature and the set temperature, automatically choosing to blow "pure cold air" or a "mix of cold and hot air" and setting the fan speed accordingly. Therefore, the set temperature has no relation to fuel efficiency; using the air conditioning will always consume more fuel.

Is It Normal for Spark Plug Ceramic to Turn Yellow?

It is normal for the ceramic part of a spark plug to turn yellow. The functions of an automotive spark plug are: 1. To introduce the high-voltage electricity generated by the ignition coil into the engine cylinder; 2. To generate sparks between the spark plug electrode gaps to ignite the air-fuel mixture, ensuring normal engine operation. The procedure for removing an automotive spark plug: 1. Use compressed air or a fine hose to blow away dust and debris around the spark plug; 2. Ensure the engine is in a cold state before proceeding; 3. Immediately protect the spark plug installation port after removal to prevent debris or dust from entering the cylinder; 4. Avoid damaging the insulating ceramic body when using a wrench; 5. Do not bend or strike the center electrode when adjusting the spark plug gap.

What are the precautions when picking up a car at a 4S store?

When picking up a car at a 4S store, pay attention to checking whether the paint surface has defects, checking the production date, checking the buttons inside the car, and checking various materials of the vehicle. Check whether the paint surface has defects: When the car leaves the factory, the paint surface is smooth and flawless because new cars are also inspected before leaving the factory. However, during transportation from the manufacturer to the 4S store, the car may suffer scratches. Some dealers may repaint it and sell it as a new car. Therefore, when picking up the car, be sure to check whether the paint surface is smooth and flawless. If there are defects, it may be a damaged car that has been repainted. Check the production date: If a car is not sold within a few months after leaving the factory, it becomes a stock car. When picking up the car, check the production date. Check the buttons inside the car: The car has many configurations, and most functions are controlled by the buttons inside the car. When picking up the car, be sure to test whether all buttons are functioning properly. The best method is to open and experience all buttons that can be opened. Check various materials of the vehicle: These include the purchase invoice, certificate of conformity, vehicle consistency certificate, motor vehicle registration certificate, three-guarantee certificate, vehicle user manual, and new car delivery confirmation form. If the 4S store is responsible for license plate registration and insurance, you also need to obtain the original insurance policy, insurance invoice, compulsory traffic insurance invoice, vehicle and vessel tax invoice, purchase tax invoice, tax payment certificate, and compulsory traffic insurance label from the salesperson.

Should You Use External or Internal Air Circulation for Car AC in Summer?

In summer, using the external air circulation mode in a car's AC system can quickly introduce fresh air into the vehicle; while the internal circulation mode enables faster cooling of the cabin and blocks harmful external gases. Whether heating or cooling, to rapidly achieve the desired cabin temperature initially, windows are usually closed. Over time without fresh air intake, the cabin air becomes stale - this is when you should switch to external circulation to allow fresh outside air in. Methods for using and maintaining car AC systems include: 1. Avoid setting temperature too low; 2. Adjust vent direction properly; 3. Don't use continuously for extended periods; 4. Occasionally use higher fan speed; 5. Turn off AC during low-speed driving.
