Is it okay to turn off the engine without turning off the air conditioner, and turn off the engine d

Always turn off the air conditioner before turning it off. Due to the high humidity of the air in spring and summer, the moisture in the air condenses into water when passing through the air conditioner, which will adhere to the surface of the evaporator"Stinky sock smell"or"Sour"The reason for this, properly turning off the air conditioner will make us unaffected by the smell of the air conditioner. Before the engine is turned off, do not rush to turn off the air conditioning system, you can first cut off the air conditioner, so that the fan works for 2 to 3 minutes, and then the air intake mode should be placed in the internal circulation, so that the air will dry the surface of the evaporator that no longer produces condensation, remove the environment for bacterial breeding, and the odor will not be generated.

Many car owners often think of turning off the air conditioner after the engine is turned off, which is harmful to the engine, and the next time the vehicle starts, the engine will start with the air conditioning load, and the high load will damage the engine.

That's because the generator can't get any electricity when you're idling, plus the battery isn't very much power, you can turn on the air conditioner at high speed, try it and see if he turns it off.

OK. Turning off the engine without turning off the air conditioner does not harm the car itself, but it has a certain impact on the air conditioning system, because the air conditioning compressor is always working if the air conditioner is turned off, so that there will be condensation on the surface of the evaporator, which is easy to cause mold and odor.

Therefore, it is recommended to cut off the compressor before stopping, and then let the ventilation function work for a period of time to ensure that the surface of the evaporator is dry. Just like after a home air conditioner is shut down, the blower will work for a while, mainly to get wet.

The quality of the current on-board battery and various protection measures for on-board equipment have been greatly improved and improved compared with the past. As long as the capacity of the car battery is sufficient, it cannot be said that turning off the engine without turning off the air conditioner must be harmful to the car.

The big problem is no, but in this way, the air conditioner will start at the same time when the next time the ignition is ignited, and the instantaneous current load will be too large, and the battery life will be shortened. After several practices, it was found that if the air conditioner is not turned off and the engine is turned off, adjusting the windshield to 0 seems to also play a role in turning off the air conditioner. The next time the lighter air conditioner will not start, the windshield must be turned on before the air conditioner starts.

Automotive air conditioning device (hereinafter referred to as automobile air conditioner). It is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, provide a comfortable riding environment for the occupants, and reduce the fatigue of the journey; Ventilation devices that create good working conditions for drivers and play an important role in ensuring safe driving. It generally includes refrigeration units, heating units and ventilation units.

This kind of combined device makes full use of the limited space inside the car, has a simple structure and is easy to operate, and is an internationally popular modern automobile air conditioning system.

The automotive air conditioning and refrigeration system consists of a compressor, a condenser, a liquid storage dryer, an expansion valve, an evaporator and a blower. Copper pipes (or aluminum pipes) and high-pressure rubber pipes are connected into a closed system between the components. When the refrigeration system works, the refrigerant circulates in different states in this closed system, and each cycle has four basic processes:

1. Compression process: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses it into high-temperature and high-pressure gas and discharges it out of the compressor. 2. Heat dissipation process:

The superheated refrigerant gas at high temperature and high pressure enters the condenser, and due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid and discharges a large amount of heat. 3. Throttling process: The volume of the refrigerant liquid with higher temperature and pressure becomes larger after passing through the expansion device, and the pressure and temperature drop sharply, and the expansion device is discharged in the form of mist (fine droplets).

4. Endothermic process: the mist refrigerant liquid enters the evaporator, so the boiling point of the refrigerant is much lower than the temperature in the evaporator, so the refrigerant liquid evaporates into gas. During the evaporation process, a large amount of surrounding heat is absorbed, and then the refrigerant vapor at low temperature and low pressure enters the compressor.

This process is repeated to reduce the temperature of the air around the evaporator.

Since the opening and closing of the air conditioning system are controlled by the air conditioning clutch, if the air conditioning is not turned off, it is not a big problem for the air conditioning compressor to turn off or start directly.

However, the blower is directly controlled by the ignition switch (key door), and if the vehicle's electrical system is not good, it is best to turn off the air conditioning blower when the vehicle is started.

Car air conditioning, car stalling, car information, car knowledge, car service.

If you don't turn off the air conditioner AC before the vehicle turns off, the compressor will be burned out after a long time!

There are many reasons to turn off the flame:

1. Driving habits and technical problems, the comfort of the manual car mainly depends on the control of the clutch, the clutch must be put gently, because the traffic light you want to start quickly is easy to turn off a little faster, especially for small displacement cars, even the old drivers often turn off, because of the displacement power problem to find the best connection point, a little lower on the flameout.

2. Use high-standard, high-quality and qualified fuel.

3. Clean the oil circuit thoroughly, including fuel injectors, throttle valves, fuel tanks, etc. It may be that the quality of the oil you add is not up to standard, there is too much grease, the oil path is blocked, and the oil attack is not smooth.

4. The main reason for the failure of the car to stall in the idle state is due to too much dust in the air, and there is a lot of dirt deposited at the valve core of the idle motor and the throttle seat when the engine is running. The solution to this problem is simple: just clean the idle motor.

5. Whether the oil circuit is smooth or not, which is also easy to cause the engine to stall halfway.

6. Due to the price of oil, coupled with the return of many people's hobbies - cycling, walking to work has increased, so new cars have been parked for a long time and are not used. In fact, it is important not to park it for a long time. In case of a long parking time, you should do a thorough maintenance before re-use, change the oil, filter, etc., and check the fuel, electrical circuit, etc. as appropriate.

It is possible that your vehicle is due to lubrication or electrical problems due to prolonged parking.

In short, whether it is a new car or an old car, whether it is an automatic or manual transmission, whether it is a veteran or a novice, it is best to add a high grade of oil when refueling, even if it is more expensive, it is worth it, so that you can protect your engine from carbon deposits. In addition, regular maintenance is also crucial, and the oil circuit and circuit are always checked to see if they are unblocked.

Turning off the air conditioner is harmful to the engine. If the air conditioner is not turned off after the engine is turned off, the engine will also start with the load of the air conditioner the next time the vehicle starts, so doing so will damage the engine. The correct thing to do is to turn off the air conditioner and then turn off the engine after parking.

First, turning off the air conditioner after the engine is turned off, which is harmful to the engine. It is highly discouraged to turn off the air conditioner after the engine is turned off, and it should be turned off after the car has been parked. It also gives the vehicle a starting time, two or three minutes after the vehicle starts, and then turn on the air conditioner, so that the engine will not be damaged, and it will also prolong the life of the engine.

Many people turn off the engine first and then turn off the air conditioner, which is wrong.

Second, the right thing to do is to turn off the air conditioner before parking the car. After stopping the car and turning off the ignition, it is also important to note that there is a correct step to turn off the air conditioner. A minute or two before turning off the fire, turn off the air conditioner, but don't turn off the fan, wait for a while, wait for the fan to blow for a while, turn off the air conditioner, and then turn off the fire.

This is also good because it prevents mold in the air duct and also protects the engine from being subjected to such a high load when the car starts again. So don't underestimate the steps to turn off the air conditioner, it's also very important.

Third, the car air conditioner should also be regularly maintained, and the water tank and condensate should be cleaned regularly. Car air conditioners also need to be maintained, replace the air conditioning filter regularly, and replace it with a new one if it is dirty. The water tank and condensant will also become dirty, which will also affect the cooling effect of the air conditioner, which will increase fuel consumption and affect the engine.

Therefore, it is also necessary to clean the engine compartment, water tank and condensate.

And you need to pay attention to the use of air conditioning on the car, otherwise it will affect the engine. Don't leave the air conditioner on for a long time, don't leave it on all winter, don't turn on the internal circulation as soon as you enter the car, and don't leave the internal circulation on for a long time. The most important thing is to turn off the air conditioner for two or three minutes before turning off the engine and maintaining it well, so as to prolong the service life of the car.

It is harmful to the engine, because the engine will run when the car is started, and the air conditioner will also be used to roll this tomb, which will also have a certain impact on the engine, and it will cause damage to the engine after a long time.

The engine can be very harmful, and it can also affect the service life of the car. Therefore, the air conditioner should be turned off before turning off the engine.

There is no harm in doing it because the car has automatically turned off the air conditioning when you turn off the engine.

The timing of planning is very risky, and it can also affect the handling life of the car. Therefore, the air conditioner should be turned off before turning off the engine.
