Does it really cost fuel to turn on the heater in the car? Does it cost to turn on the heater in the

Definitely the oil, the reason. The engine should ensure that the temperature of the body is 80-90 degrees when working normally, if the hot air is turned on, the temperature of the engine will drop, and the consequence is that the engine should increase the idle speed to increase the water temperature, (in winter, when the car is just started in the morning, the speed of the machine will also reach about 1200, the purpose is to increase the water temperature, improve the heat of the engine, so that it reaches the working temperature of 80-90 degrees), so the fuel consumption of increasing the speed is the fuel consumption of the heating, of course, the engine has been running at high speed, For example, at high speeds, there is basically no idling, and there will be no excess fuel consumption. Conclusion.

Turning on the heater will also produce a certain amount of fuel consumption, of course, it is much less economical than turning on the air conditioner.

The refrigeration compressor consumes a lot of engine power and consumes significant fuel. Heating is basically the use of the residual temperature of the engine, should not directly consume fuel, however, the heater motor needs electricity, power consumption will indirectly bring fuel consumption, but this consumption is basically negligible. Some friends feel that electricity is in the car, as long as the engine turns, it will generate electricity, and there is no need to use it in vain.

Actually, this is a misconception, and this is indeed the case with DC generators in the past, which will generate electricity as long as the generator rotates. And now the alternator, as long as there is no current consumption, the generator idles, does not generate electricity, and the power consumption when idling and generating electricity is not the same, friends who often drive will pay attention to the point will find that when the fan belt is loose, the sudden acceleration belt will scream, and sometimes it is not screaming, but when you turn on the headlight, the belt will also scream, at this time turn off the headlight, the belt will stop screaming, indicating that when the generator generates electricity, the running resistance does become larger, causing the belt to slip and whistle.

As long as you don't turn on the air conditioner, just turn on the fan, use the heat energy of the engine itself, no fuel, the heat itself must be dissipated, the fan uses the electricity of the battery, you don't turn on the headlights during the day, the excess electricity generated by the generator is stored...

In winter, it does not cost oil to turn on the heater. At present, most of the car heating system adopts water heating, in more popular terms, that is, the car heating system only uses the waste heat of the engine, so the heat emitted by the engine work does not affect the fuel consumption of the car, and it can even be said that turning on the heating air is only equivalent to connecting the entrance of the air inside the engine.

However, from another point of view, winter will indeed increase fuel consumption, although the heating system only transports the waste heat of the engine, but when the temperature in the car does not meet the requirements, the engine needs to do extra work to transport heat, which will naturally increase fuel consumption.

The following are the precautions for turning on the warm air in winter:

1. The working principle of the air conditioner and the air conditioner of the car is the same, it is necessary to liquefy the refrigerant through the compressor of the air conditioner, absorb the heat in the car to cool down, and the use of the compressor will increase the load of the engine, so the fuel consumption will increase.

But the warm air is different, the car's water tank is the first of the warm air heat, through the blower to transmit the warm air into the car, and the heat is originally generated by the car during driving, so do not use the compressor to work. This does not increase the load on the engine and does not increase fuel consumption.

2. The correct way to turn on the heater without fuel is to start the engine first and let the car run normally for a period of time, so that the car water tank will have a certain amount of heat, and then turn on the heater. And set the air circulation to external circulation, so that the cold air in the car is discharged first, and then set to internal circulation, so that there will be no load on the engine and fuel consumption will not increase.

Turning on the heater of the car will not affect the fuel consumption of the vehicle, because the heating of the vehicle air conditioner is through the transfer of the heat from the engine to the cab to heat.

According to the type of heat source, the automobile heating system is mainly divided into two types: one is to use engine coolant as the heat source (currently used by the vast majority of vehicles), and the other is to use fuel as the heat source (used by a few medium and high-end cars). When the engine coolant temperature is high, the coolant flows through the heat exchanger (generally known as the warm air small tank) in the heating system, and the air sent by the blower is heat exchanged with the engine coolant, and the air is heated and sent into the car by the blower through each air outlet.

Turning on the heater in the car will consume a little more fuel. When the heater is turned on in winter, the engine needs to consume a part of the oil to heat the heat, the colder the conditions, the more heat is needed, which will affect the water temperature of the water tank to decrease, and the water temperature will be reduced to slightly reduce the thermal efficiency of the engine, resulting in a slight increase in fuel consumption, so the colder the weather, the more slightly more fuel consumption will be turned on the heater.

Pay attention to the air conditioning in the car in winter.

In the mode of turning on the internal circulation of the heater and air conditioner for a long time, the air in the car is not fresh, especially the space of the car is not large, so in winter, the car must pay attention to opening the window regularly for ventilation; When turning on the heater in the car, it is best to open the windows ajar to allow the air to circulate to a certain extent, and turn on the convection mode to prevent the car from drying out and improve the air quality in the car.

Note that after using the air conditioner, before parking, the air conditioner should be turned off, and the warmth in the air conditioner can also be maintained for a short period of time, so there is no need to worry about being too cold, and at the same time, the external circulation system should be turned on, so that the air duct of the air conditioning system can be cleaned to avoid breeding bacteria.

I think this question needs to be analyzed on a case-by-case basis:

1.When you turn off the fan and turn it on to the outer circulation (red) to turn on the heater, it is not fuel-efficient, but it is an environmentally friendly practice. Because the heat of the warm air is the extra work done during the operation of the engine, if the warm air is not turned on, this part of the energy will be dissipated into the atmosphere through the cooling system such as the water tank and the heat sink with the help of antifreeze circulation, why not turn on the blower, just turn on the red blue switch that adjusts the temperature to the red side, and there will be warm air blowing out slowly?

In fact, if you turn on the heater when the car is cold, you will not get the heater and will prolong the warm-up time, so generally do not turn on the heater switch before the water temperature comes up, and you should turn the red blue switch that adjusts the temperature to the blue side, so that the warm water switch is turned off. After the water temperature is normal, turn the red blue switch to the red side and turn on the blower.

Although the blower is not turned on, if the ventilation system is in the external circulation, because the vehicle is moving forward, the external air is blown into the warm air tank box through the external circulation valve, bringing the hot air into the car, so you will feel that there is warm air blowing out slowly, if you change to internal circulation, there will be no such phenomenon.

As long as the red blue switch that adjusts the temperature is turned on the red side, even if the blower is not turned on, the coolant is already circulating in the heating system, which is true.

In order to keep the engine water temperature normal, once the water temperature exceeds the standard, the electronic fan will start to help the water tank dissipate heat, after the water temperature is normal, the electronic fan stops working, and so on and so on, to keep the water temperature normal, if the heater switch is turned on, the coolant will flow into the heater water tank, the heater water tank can help the coolant dissipate heat, so that the frequency of the electronic fan switch decreases, which is beneficial to the vehicle, and there is no saying that it costs fuel.

2.When the temperature is too low, turning on the heater will consume more fuel! Because when the temperature is too low, even if the coolant circulation is not turned on and the fan is not started, the heat generated by the engine will be quickly dissipated, and the engine must increase the gasoline combustion to ensure the optimal working temperature.

In order to maintain the temperature in winter, most of the engines are in a small cycle state; And when you turn on the heater, the cool air inside the car flows quickly through the surface of the exchanger, which actually adds an efficient radiator to the engine's cooling cycle! Especially when you open the external circulation, its powerful cooling effect can be imagined, the computer will instruct to increase the amount of fuel injected and change the ignition advance angle to maintain the necessary operating temperature. So it's best not to use the heater when the water temperature of the car doesn't reach normal.

3.Turn on the air conditioner, fan, compressor is working, it must cost oil, because the power consumption of the air conditioner during heating is higher than that during cooling, so this state is more fuel-intensive than turning on the air conditioner in summer.

It costs fuel to turn on the air conditioner in the car, and it does not consume fuel to turn on the air conditioner in winter.

Warm air comes from the heat generated when the engine is working: when the cooling system of the engine dissipates heat from the engine, the heat emitted by the fan is sent into the car to form a warm air; When the heater is not in use, the fan stops and the hot air outlet closes, and the heat is completely dissipated into the atmosphere. Therefore, car heaters are reused as waste and do not consume fuel.

The AC key is the switch of the air conditioner compressor, and if you use the air conditioner in summer, you must turn on the AC button, that is, turn on the cold air; The heater only uses the heat circulation inside the car, and there is no need to start the air conditioning compressor at all, so you only need to adjust the air conditioning button to turn on the heater, and you don't need to turn on the AC switch.

They all say that it doesn't cost gas, but I turn on the heater (don't turn on a c), and the fuel consumption has increased significantly, and the fuel consumption has increased many times.

In winter, the weather is cold, the engine temperature is low, and turning on the heater just after starting will increase fuel consumption to a certain extent.

Both cold and warm are expensive, and warm is more expensive than cold.

It doesn't cost fuel to turn on the heater in the car.

The heating mode of the car air conditioner does not consume more fuel in the car. The car air conditioner is only in refrigeration mode when it is runningAir conditioning compressorwill run, and will consume the power of the engine, thereby increasing the fuel consumption of the car.

In winter, it is fuel-free to turn on the heater in the car. At the same time when the air conditioner and heating are not started at the same time, that is to say, the A C button is not turned on, the heating is the cooling system of the engine, and when the cooling system dissipates heat from the engine, the small fan will rotate, and the heat will be introduced into the car and become a warm air.

When the heating is turned off, the fan stops spinning, the hot air vent closes, and the heat dissipates into the atmosphere. Car heating is equivalent to waste reuse, and does not consume fuel.

Does it cost oil to turn on the cold air?

But in winter, when the car is just started, immediately turn on the warm air mode, which will naturally increase fuel consumption, although the heating system is only to transport the waste heat of the engine, but the temperature in the car is still relatively low at that time, when it does not meet the requirements, then the engine needs to do work, additional heat delivery, so that the amount of fuel will be consumed.

In winter, it is necessary to pay attention to the heater in the car: turn on the heater for a long time, in the mode of internal circulation, the air does not circulate out in the car, resulting in the air in the car is not fresh, and the non-hitching wheel is often dull.

If you turn on the air conditioner, it is different, because they work differently, the cold air requires the compressor to pass through the pressurization to make the refrigerant.

Liquefaction and re-vaporization, cooling by absorbing heat from the air to achieve the effect. When the air conditioner is turned on, the meshing is connected, and the pulley of the compressor drives the compressor to work, and the engine load increases, requiring a certain amount of oil.

The car heater does not cost fuel.

It does not consume fuel to turn on the heater in the car, because the heating in the car is provided by the car's cooling system, and it has nothing to do with the speed and power of the engine. In winter, the water temperature of the engine is used to warm the air, so when the heater is used in winter, the air conditioning compressor is not working, and the fuel consumption will not increase.

However, when the car is just started or the car is still warm, do not turn on the heater, because the engine is not yet hot, and the cold air blowing in is also blowing in, which also consumes electricity in vain and increases the load on the engine. At the same time, when the car is just started, it takes a certain amount of time for the oil to lubricate the various components. If the heater is turned on at this time, the internal lubrication of the engine is not enough, and the frictional resistance increases, resulting in excessive load on the engine, which will consume fuel.

Precautions for driving the heater

1. The warm air is not suitable for blowing directly on the head, and blowing it for a long time will cause fatigue to the driver and affect driving safety, so it is recommended to open the small gap in the window to circulate the air in the case of long-term use of heating to ensure the oxygen content of the air in the car and make the driver sober.

2. Some car owners are accustomed to resting in the car, and must not keep the heater on when sleeping in the car, because this is very easy to cause carbon monoxide poisoning.

3. After turning on the heating, the car is a confined space, so that it brings a good environment for bacteria to breed and spread, if this is someone smoking in the car, the amine and nicotine in the smoke and dust will be attached to the surface of the evaporator, in the condition that the air conditioner is not commonly used, the situation of rainy days, the bacteria will spread on the surface of the evaporator, and the air pollution in the car will be caused when the air conditioner is turned on again.

In the cold winter, the heating source of the car comes from the engine to accompany the waste heat, so the heating method avoids the waste of heat to the greatest extent, and the heating effect is not bad, the compressor, that is, AC does not need to work, the only thing that the blower needs to consume is the power of the car Huling, if the wind is a little smaller, the engine heating will also come, and the system of charging the car is to use the remaining energy between you stepping on the accelerator, loosening the accelerator and stepping on the brakes. It's just that in this regard, looking at the technology of each car, I have learned that the conversion efficiency of Mazda is quite good, so it almost does not consume any fuel to turn on the heater.
