It is not advisable to spray 75% alcohol in a car because alcohol is a flammable and explosive substance. When exposed to sunlight, the temperature inside a closed car can reach 50-60 degrees Celsius. In a poorly ventilated environment, if there is an open flame or something that aids combustion, such as lighting a cigarette, an explosion may occur. If you need to disinfect with alcohol, it is better to use a wiping method instead of direct spraying. Before using 75% alcohol to disinfect the vehicle, turn off the engine and keep the car in a non-operational state. At the same time, ensure proper ventilation in the car. Since the flash point of 75% alcohol is around 22 degrees Celsius and alcohol evaporates quickly, car owners must ensure there are no open flames nearby and be mindful of the amount of alcohol used to avoid high alcohol concentration in the air, which could lead to an explosion.

Why does the engine malfunction light come on after flooring the accelerator?

Flooring the accelerator may cause the engine malfunction light to illuminate due to poor fuel quality. Here are other potential reasons for the light to come on: 1. Carbon deposits in the intake tract or piston crown can lead to poor atomization: This results in incomplete combustion, triggering the warning light. 2. Cold engine starts: Particularly when ambient temperatures drop sharply, insufficient light may occur due to ECU temperature calibration issues during startup. However, the condition stabilizes once temperatures drop to a certain level without fluctuation. 3. Excessive engine mileage: Weakened spark plug performance characteristics may activate the warning light, suggesting a need for professional inspection at a repair shop.

What are the reasons for the Baojun 560 air conditioner not cooling well?

The reasons for the Baojun 560 air conditioner not cooling well may include refrigerant leakage, damage to the room temperature sensor, or a blocked expansion valve. Refrigerant Leakage: If both the indoor and outdoor units are working and the compressor is also functioning, it could be due to refrigerant leakage. If the compressor does not rotate and overheats, it might be caused by a damaged compressor capacitor. A dirty condenser can also reduce the cooling efficiency of the air conditioner. Room Temperature Sensor Damage: If the air conditioner stops working once it reaches the set temperature, it may be due to a damaged room temperature sensor. Blocked Expansion Valve: A blocked expansion valve in the air conditioner prevents the refrigerant from circulating properly, resulting in no cooling.
