What are the hazards to the body when turning off the engine and then turning off the air conditione

<> air conditioning is a very great invention of human beings, which has brought us a lot of convenience. There are many friends who turn off the engine directly when parking without turning off the air conditioner. So, is the use of car air conditioner to turn off the engine and then turn off the air conditioner?

Or turn off the air conditioner and then turn it off? Let's talk about it now!

Turn off the engine and then turn off the air conditioner, in fact, this is very harmful to our car, because our car turns off and then turns off the air conditioner has a great harm to the engine, our car will start with the load of the air conditioner the next time, so such a high load will damage the engine.

Our best practice is to turn off the air conditioner a few minutes before we reach our destination, so that the natural air can be turned on, so that the temperature in the air conditioning duct will rise, eliminating the temperature difference with the outside world, so as to keep the air conditioning system relatively dry and avoid mold growth. And you should also turn on the air conditioner after the vehicle has been started for two or three minutes and the engine has been lubricated.

Many people do not know much about the use of air conditioners, once the operation is wrong, it will not only affect the performance and life of our car air conditioning system, but also damage the health of us and our families!

Some local tyrant friends may say: No! Our BMW Mercedes-Benz didn't see the power cut off at the moment of starting.

ActuallyUninterrupted power for a high-end car does not mean that it will not automatically protectIt is because such a high-end car has more sufficient power to maintain the starting consumption, which can ensure that the power consumption of the driver and passengers is not affected, it takes into account the driving experience of the driver and passengers, not that it does not have protection means inside the engine compartment.

Today's car computer has a lot of protective instructions, and some operations that are really harmful to the vehicle will be optimized or refused to be executed by the engine computer. You can take a closer look, sometimes, even if the air conditioning switch is pressed, the compressor will not start immediately, that is, the protection program is controlled according to the situation at that time. Neither the starting motor nor the engine is affected by whether the air conditioning switch is turned on or not, so you don't have to tremble at all, and even if you don't turn off the air conditioner sometimes, the car won't be good.

Turn off the engine and then turn off the air conditioner when driving. There is a lot of cold air in the air duct of the air conditioner that cannot be discharged, and it is easy to breed a large number of bacteria. The next time you turn on the air conditioner, these bacteria can easily be inhaled into the body and cause respiratory diseases. There is also the easy loss of battery power.

If you turn off the air conditioner first, the compressor will not be turned off, which will have no effect on the body, but will cause the air conditioning pipe to be damp and smelly.

Turn off the engine and then turn off the air conditioner, it will hurt the car more, first of all, the power will suddenly fail, the air conditioning compressor may burn out, and the next time the lighter compressor will start directly. Secondly, there may be water in the air conditioning ducts, which should be closed to blow natural air to dry it and avoid the growth of bacteria.

I'm sure we've all had experiences with fires and turning off air conditioning. Does this hurt the car? This is a concern for many.

If the air conditioner is turned off, the starter motor should not only drive the engine, but also the air conditioning compressor the next time the air conditioning cycle is started. If it is subjected to high loads for a long time at the time of starting, it is easy to damage the starter and battery. It is believed that the air conditioner was not turned off in advance before extinguishing the fire, the fan kept blowing for a while, and the moisture in the pipes was blown dry.

After parking, there will be water vapor condensation in the air conditioning system, which is easy to breed bacteria, leading to mildew and odor problems! Is it really necessary to turn off the air conditioner before turning off the engine?

<> the absence of air conditioning has no effect on the engine, the first start does not spin the compressor and does not increase the unnecessary load on the starter. Because when the vehicle starts, almost all the electrical appliances on the car are in a state of power loss, all the current and voltage are concentrated on the starter, the air conditioning panel has no electricity, and the compressor will not start naturally. When the vehicle starts, about 3 to 5 seconds with a barrage, the compressor will start working.

A compressor with an electromagnetic clutch can hear a "pop", which is the sound of the compressor sucking in.

Turning off the air conditioner directly or letting the air conditioner start the vehicle automatically will cause great damage to the car, and the car does not turn off the stupid Hu air conditioner, resulting in the instantaneous power load of the vehicle being too high, and it is easy to scrap the engine for a long time, and it will also cause great wear and tear to the battery. So, make sure that you don't turn off your air conditioner until you turn it off. The battery is the power supply of the car, from the lighting and air conditioning to the start of the car are inseparable from the battery, the life of the battery is generally about 2-3 years, if the car always turns off the air conditioner will increase the burden on the battery, the life of the battery will be greatly shortened.

When the car starts, the air conditioning system does not run. Even if the air conditioner is turned on, it will not run, so the load on the starter will not increase, which also reduces the load on the battery. Do not turn off the engine first and then turn off the air conditioner.

Turning off the engine and then turning off the air conditioner will cause damage to the engine as the engine will start with the load on the air conditioner and then aggravate the damage to the engine.

If the air conditioner is not turned off before the engine is turned off, the cooling and heating systems of the air conditioner in the car will be affected, and some adverse reactions may occur. Therefore, the air conditioner must be turned off before the flameout is defeated.

It may affect the life of the vehicle engine, increase the work burden of the jujube rolling engine to a certain extent, and the coarse rock will also damage the battery device on the vehicle, resulting in excessive battery loss.

This will cause serious damage to the vehicle's engine and battery, which is easy to shorten the life of the vehicle and increase fuel consumption.

If you don't turn off the air conditioner before the car turns off, if you start the car directly next time, it will cause damage to the car's air training beam compressor and engine. The most correct way is to check whether all the electrical equipment on the car is turned off before the car is turned off, if it is turned off, the vehicle can be turned off, and if it is not done, it is easy to cause the vehicle to suffer corresponding damage. <>

Because we all know that the air conditioner of the car is a high-power electrical appliance, if you do not turn off the air conditioning system in advance before the car turns off, then the damage to the air conditioning compressor is very large, because the car has not turned off the compressor of the air conditioner is running, and it takes a lot of electricity in the whole operation process, if you do not turn off the air conditioning system in time, and suddenly turn off the car again, then the impact on the electronic sensors of the air conditioning compressor is great. If this is the case for a long time, it is easy to lead to the scrapping of the air conditioning compressor. <>

And for this behavior not only to cause damage to the air conditioning compressor, but also to a certain degree of damage to the engine, because the air conditioning compressor needs external transmission of force when compressing air, and this power comes from the engine, because the engine has to do a part of the work to the compressor to work, so the load of the engine increases, resulting in an increase in the amount of fuel injection in the engine cylinder, if you suddenly turn off and the air conditioner is not turned off, it will form idling, This will cause an increase in carbon deposits inside the engine, which will affect the life cycle of the engine. <>

In general, the damage to the car is very great if the air conditioner is not turned off before the car is turned off, so it is recommended that the majority of drivers must check whether the air conditioner is turned off before the car is turned off. And this phenomenon of turning on the air conditioner generally exists in summer, because the summer is hotter and the car turns on the air conditioner more often, so the majority of drivers must pay attention to this detail.

If the air conditioner is not turned off before the car is turned off, the next direct start will cause damage to the car, but the damage is not too big and will increase the burden on the battery.

I don't think there will be any damage, because the high-power appliances in the car will automatically turn off when they start.

I think it hurts, because the next time you start the hot car, you need to drive the compressor to run, so the load is greater and it is easier to generate carbon deposits.

When the car is in an idle state, the engine needs to overcome the frictional resistance of its internal parts, and does not output power to the outside world, and the fuel combustion is insufficient, which is easy to produce carbon deposits in the cylinder and the throttle, and will also increase fuel consumption. The fuel consumption of the car is higher when the air conditioner is turned on at idle. On the other hand, gasoline is wasted, and it also does a lot of damage to the engine and battery.

When the engine is idling, the exhaust gas often contains a large amount of carbon monoxide due to insufficient fuel combustion, and the carbon monoxide emitted with the exhaust gas may collect around the vehicle and enter the vehicle through the air conditioning system. In addition, when the air conditioner is turned on, the windows are closed and the air is not circulated, and the carbon monoxide concentration in the car will become higher and higher over time.

Notes:

In the season when the air conditioner is used frequently, you may wish to do more air conditioning pipe cleaning and disinfection, so that the air conditioner refrigeration effect is better. Before turning off the heat, make it a good habit to turn off the air conditioner in advance.

Before stopping at the destination, turn off the air conditioner and turn on the natural air, so that the temperature in the air conditioning duct can rise and eliminate the temperature difference with the outside world, so as to keep the air conditioning system relatively dry and avoid a large number of mold multiplication caused by moisture.

What damage does the car do to the engine if the air conditioner does not turn off? Many car owners like to start the air conditioner when parking on the side of the road for a long time, which will definitely increase fuel consumption, but it is not just as simple as fuel consumption, and there are other problems and hidden dangers in idling the air conditioner.

1. Cause carbon deposition in the engine.

When the engine is idling, because the throttle is in a critical closed state, the air intake is very small, and the engine at this time is in a concentrated injection state, and the carbon deposit will be relatively more due to the excessive concentration of the mixture. If the air conditioner is turned on again, this requires a certain amount of power output, and the engine will increase its speed appropriately in order to avoid stalling, generally about 50 rpm, which will lead to more carbon deposition when running at low speed with load.

When the engine carbon deposition is serious, it will affect the oil lubrication, cause the engine to detonate, block the three-way catalytic converter and oxygen sensor, and then lead to a more serious vicious circle, affecting the operation of the engine and eventually leading to serious engine failure.

2. It may be life-threatening.

The car idles on the air conditioner for a long time, due to the excessive concentration of the mixture and insufficient combustion of the engine, which will lead to the generation of a large amount of carbon monoxide, which is slightly lighter than the air, and will gather around the body when there is no wind in the place, and may re-inhale the air conditioning system, which will lead to suffocation of the people in the car due to lack of oxygen, and the danger will occur.

Generally speaking, there is a certain amount of damage to the engine when the air conditioner is turned on at idle speed, but the life of the engine is very long, and its stability and durability have been verified in many ways. Therefore, it is not recommended to idle the air conditioner in place to rest in the car, because the case of death due to exhaust poisoning is not once or twice, I hope that all car owners will take warning.

The consequence of the owner not turning off the air conditioner directly is that the vehicle will ignite under the pressure of starting the air conditioner the next time, which is easy to damage the engine and battery and shorten the service life. There is also a disadvantage, that is, it will make the evaporation box damp, resulting in a large number of molds in the air conditioner, causing the air conditioning odor, making the air in the cabin turbid, and affecting the health of the owner.

The consequences of turning off the engine without turning off the air conditioner are as follows:1. The next time you start the car, the compressor will rotate with it, increasing the load on the motor; 2.engine damage; 3.It breeds bacteria. Features of the air conditioner:1. Utilize refrigerants.

The continuous abnormal circulation achieves the refrigeration effect; 2.Remove dust, odor and smoke from the air in the car, make the air in the car fresh, humidify the air in the car, and improve the relative humidity of the air in the car.

The maintenance method of the air conditioner is as follows:1. The temperature should not be too low; 2.control the direction of the air outlet; 3.Do not use for long periods of time; 4.Appropriate opening of large air volume; 5.Turn off the air conditioner when driving at low speeds.

Occasionally forgetting to turn off the air conditioner after turning off the engine will have no effect on the car. The effect of forgetting to turn off the air conditioner when the engine is turned off is mainly that the pressure of the next start of the air conditioner will cause the vehicle to ignite, which will easily damage the engine and battery and shorten the service life. Turn off the air conditioner 7 minutes before turning off the fire, and the remaining hot air will dry the moisture in the evaporation chamber and eliminate the temperature difference with the outside world, thereby reducing the odor of the air conditioner and maintaining the air conditioning system.

Relatively dry. <>

When the car is started or turned off, all other components that are in use, such as the air conditioner or stereo, are automatically temporarily turned off, and all power is concentrated in the engine as the starting power. When the process is over, the air conditioner will automatically turn on again. Repeated switching in this way will consume the battery, which will have a certain impact on the life of the battery and the air conditioner.

Turning off the engine without turning off the air conditioner still has a certain impact on the car, which is mainly reflected in the humidity inside the air conditioning duct. When the automobile air conditioning system is operating normally, the surface temperature of the air conditioning evaporation box is very low, and there is a large amount of water vapor.

It will condense on it and be blown into the air duct by the air conditioner, resulting in a high humidity inside the air duct, so that a large number of molds will multiply in it, resulting in air conditioning odors, etc. If we turn off the air conditioner switch a few minutes before the engine turns off, but keep the fan running, the temperature inside the air conditioner evaporation tank and the air conditioner duct will rise, and the moisture inside will evaporate, so that the air conditioning system will remain relatively dry, which can avoid the breeding of mold, which is still very good for our health.
