What is the reason for the increase in fuel consumption after turning on the warm air in the cold wi

Of course, because the temperature in winter is very low, the heat of the engine will also produce losses, so it is often appropriate to increase the amount of fuel injected to maintain the ideal working condition of the engine, to give a simple example, usually the ideal working temperature of the Japanese car engine is between 90-95 degrees, and the normal fuel consumption can be maintained in summer, and to -30 degrees in the northern alpine region, the same amount of fuel injection is difficult to ensure the normal temperature of the engine, due to the increase in heat loss, so the supplementary heat must also be improved, The supplementary heat is generated by burning more oil, so fuel consumption will inevitably increase in winter! ‍‍

There is a process of the engine temperature rising after a cold start, and this time will naturally become longer when the temperature is lower, in this case, even if you don't turn on the heater, your fuel consumption will increase. At the same time, because in a low temperature environment, the operating temperature required to maintain the normal operation of the engine will be higher than usual, so if the owner drives away immediately after the cold start, the fuel consumption at this time will also increase. ‍‍

Due to the very low temperature in winter in some areas of our country in the north, the fluidity of the car's oil has decreased a lot, due to the extremely low temperature, the water temperature rises slowly, and half of the oil temperature will not go up. ‍‍

I think you may forget to turn off the defroster, the car is driving in winter, the front gear is easy to frost, many friends are in a hurry to go to work in the morning, sometimes after the front gear glass is frosted, the result is forgotten to turn off, the heater does not cost oil, but the start of the defroster is the need for a compressor, so the fuel consumption is naturally improved, open the defroster and open the air conditioner in summer The essence is the same! ‍‍

My car is a good example, the weather is so cold this time, basically a week to get more than 200 fuel money, I think it is very common to say that the car in winter, especially in the north of the winter fuel consumption rises! In other words, as long as it is in winter, the temperature is greatly reduced, fuel consumption will show an upward trend, which has nothing to do with turning on the heater, but many friends find that the fuel consumption of the car rises in winter, and they can't find a reasonable reason, so they take the heater back to the black pot! In fact, in the north of the car, in the winter fuel consumption will be more or less, a very normal phenomenon, can not turn on the heater, fuel consumption will increase! ‍‍

I think the temperature of the car engine is relatively low when the car is started cold, and turning on the heater at this time will only increase the workload of the engine, in which case the time for the engine to reach the normal working temperature will be slower, so the fuel consumption will inevitably increase. Secondly, check if the air conditioner A C button is turned off. ‍‍

When the oil temperature is low, the condensation and fluidity of the oil will be reduced a lot, and the viscosity will also increase relatively, and the operating load of the engine will naturally increase after starting the car, resulting in higher fuel consumption. ‍‍

Heaters need to consume heat, and the heat source is the engine. When the temperature of the engine decreases, the horsepower decreases, and to obtain the same power, fuel consumption will inevitably increase. We can verify this from the lack of horsepower in cold cars. ‍‍

Actually, I think that the increase in fuel consumption is a normal thing because it needs to pull this compressor.

<> "Then let's talk about the role of this AC key first, the AC key is actually the same as the switch at home, that is the function of a switch, it controls the compressor of the air conditioner. When you turn on the air conditioner in the summer and press the AC button, the compressor starts to work, providing cold air for the car, the engine drives the compressor, and the compressor works to promote the circulation of refrigerant in the air conditioner, so as to achieve the purpose of refrigeration.

In fact, this is the same principle as the air conditioner at home, but this compressor needs to consume the power of the engine, and all the energy of the engine is gasoline, so the fuel consumption increases. When you turn off the AC button, the compressor is in a state of strike, and the air conditioner will not be able to cool.

When the heater is turned on in winter, the principle is different from the principle of air conditioning and refrigeration in the car, and most of the heating and air conditioning of traditional cars are water heating systems, so there is no concept of water heating and heating, right? To put it bluntly, the engine passes the hot coolant through this heat exchange system, which heats the air and sends it to the car to warm us.

It's a bit complicated, it's like a hair dryer at home, the resistance wire inside heats up the air that passes through it, and then blows out the hot air, which is almost the same reason. There is no need for a compressor in the whole heating process, which means that the AC button does not need to be opened.

If the AC button is turned on, the air conditioning compressor will work, and what is sent into the car is a mixture of heating and cold air, even if it blows out, it is also warm. However, the compressor eats up part of the power of the engine and wastes it, and the fuel consumption is high, so it is not necessary to turn on the AC button to turn on the heater in winter.

Generally speaking, it is fuel-efficient to turn on the air conditioner, especially in summer, usually it is necessary to turn on the AC key, which will cause the load of the engine, but it is not very fuel-consuming to turn on the air conditioner in winter, mainly to use the heat brought by the engine to work ** warm air, and at the same time, it is also a certain fuel consumption to turn on the warm air after the car starts.

Many people like to turn on the air conditioner when driving, and generally speaking, it costs fuel to turn on the air conditioner, especially in summer, when the air conditioner is turned on, they will choose to turn on the AC button, and this is also the control switch of the air conditioning compressor, which will increase the load of the engine to a certain extent after opening, resulting in a certain consumption of fuel.

But in winter, it is almost fuel-free to turn on the air conditioner, mainly in winter, the hot air that blows in is mainly the use of the heat generated by the engine when working, and finally brought into the car through the blower and fan, which is also the principle of rubber waste heat heating, and there is no need to open the AC key.

Normally, the AC button will be turned on in the summer, but when the temperature is very low, when the car starts to turn on the air conditioner, it also requires a certain amount of fuel consumption, mainly in very low temperatures, the engine has not had time to lubricate various parts, so that gasoline will be burned to cover the vertical side normally**.

It won't be high, and there is a small radiator in the car, but there will be fuel consumption when the car is parked there.

The warm air of a car is the heat generated when the engine is working. The heat is sent into the car through the fan to form a heater to achieve the heating effect. If the heater is not in use, the heater fan is turned off, the hot air vent will also be closed, and the hot air emitted by the engine will be discharged from the car and into the atmosphere.

Therefore, the use of heaters in the car driving will not increase fuel consumption. But one thing to note, the car should not be used when the water temperature does not reach the normal value, that is, the water temperature meter does not reach 90 degrees.

If the warm air is used when the team is stuffy, because the engine cooling system does not produce heat, not only will the car not be hot, but also will cause low temperature, so that the amount of fuel and cavity bending oil increases, this time is fuel-efficient, not only fuel but also cause engine wear.

As long as you avoid this, you can use it boldly, the quality of the warm air in winter is directly related to the safety of driving, so it is necessary to maintain a stable temperature.

<> "Many old drivers say that the fuel consumption of the car in winter is lower than that in summer, and the old driver's statement is that we don't need to turn on the cold air in winter, and the fuel consumption of all engines is low without additional burden." However, many new Heng and friends use the car in winter The fuel consumption is not low at all, but it feels that it is more fuel-efficient to turn on the heater, why is this?

In fact, everyone knows very well that driving in summer requires the air conditioner to stop laughing because the weather is hot, so the engine fuel consumption becomes larger. From the moment we turn on the air conditioner AC and press the sail button, the car's engine has an extra load. In addition to providing power to the car, it also needs to drive the compressor of the on-board air conditioner to work and provide energy for the on-board air conditioner**.

This AC button is the key point I want to talk to you today, although the essence of the AC button is to control whether the car air conditioner works, but many novice friends will not use it, resulting in high fuel consumption in the case of using the car to turn on the heater in winter. In fact, the old driver said that the fuel consumption of the car in winter is lower than that in summer, which is true, and the fundamental reason is indeed that turning on the heater in winter will not increase fuel consumption.

The car's heater** is generated by the engine's waste heat, which is lost with the cooling system even if it is not used to heat the air. But if you don't know how to use the AC button, even if you turn on the heater, it will also increase fuel consumption. If we turn on the AC button during the process of turning on the heater, the compressor of the car air conditioner is always working.

But since we set the warm air gear, the wind blowing into the car is warm. Since the compressor is always working, the engine will continue to need to do extra work, so the fuel consumption of the engine will increase.

Many novice friends mistakenly think that the AC button should be turned on when turning on the heater, resulting in high fuel consumption. In fact, the correct operation of turning on the heater in winter should be to turn on the ventilation system, make sure that the AC button is turned off, and then adjust the temperature control gear to the heater gear, so that the fuel consumption can be low and warm.

The engine is working normally, and there are certain requirements for water temperature. Generally, the water temperature is about 80 to 95 when the engine is working, if this temperature is not reached, the engine EFI system will increase the amount of fuel injection, and the idle speed will be relatively high. If the water temperature is not enough to turn on the heater or turn on the heater under the condition of long-term low-speed driving, it will cause the water temperature to drop or the temperature is not high enough, causing the idle speed to rise, so as to speed up the rise of the water temperature.

High idle speed will cause an increase in fuel consumption in Xunzhou. However, when the water temperature reaches the specified temperature and continues to run at high speed, the heating heat blown out by the dust machine of the warm air bridge will not affect the normal operation of the engine.

Therefore, not all heaters do not consume fuel, when driving at low speed in urban areas or just starting the vehicle, turning on the heater will lead to an increase in fuel consumption, and under high-speed driving conditions, it will have almost no impact on fuel consumption!

If the engine wants to reach the best state, the water temperature needs to reach more than 80 degrees, and if it is lower than this temperature, the engine needs to increase the concentration of the mixture to run normally, so the engine will have high fuel consumption at low temperatures. If we turn on the warm air at this time, it will not cost oil, and the warm air is the circulating water in the tank.

After the car heats up, turning on the heater should have little impact on fuel consumption, which belongs to waste heat utilization. If the engine temperature does not rise, and the heater is turned on at the same time, it will definitely cost fuel, after all, you need to increase the amount of fuel injected to increase the engine temperature. The fuel-saving state, in layman's terms, means that the hot air discharged by the air conditioner is simply taken from the waste heat emitted by the engine, and the compressor does not participate in the work, and the temperature is adjusted by the start and stop of the blower, so that the body feels dry.

If this switch is not turned off, the air conditioner heats the air when the compressor.

The power consumption of the fan can be provided by the generator, and in summary, turning on the heater in a cold car does not have much impact on fuel consumption. However, it should be noted that because it is the engine coolant heating, the water temperature has not yet come up when the car is just started, and it is not recommended to turn on the temperature adjustment button when the cold car starts. When the engine's water temperature gauge is close to "12 o'clock", that is, the engine is working properly, the button can be turned on.

In the state of internal circulation, the heating effect is better. However, after a long time, the water temperature of the water tank is definitely not enough, and it will take a while for the water temperature to rise, at this time, turning on the warm air will not only make you feel the cold wind, but also increase the burden on the engine, causing the water temperature to rise more slowly.

It must be more expensive than turning on the air conditioner in summer, the engine is extended in reaching the normal temperature, the water temperature is low, and the electronic damper is always open, and it is necessary to consume oil, for example, it takes five minutes to reach the temperature in summer and twenty minutes in winter, and there are many factors, but the fuel is definitely not increased in fuel consumption, because the heating is based on the water circulation in the engine of the car itself, and the heating fee is through the heater radiator, just add a fan to use electricity, which will not increase fuel consumption. I don't feel the increase in fuel consumption.

No, because the heating air in winter does not need to work through fuel consumption, because when driving in winter, the car will naturally generate heat, using the principle of fan operation, which will increase the consumption of electricity and will not use oil.

Yes, as long as you use this function, it will increase the fuel consumption of the car, whether it is warm air or hot air, it will consume a certain amount of oil.

Yes, the general vehicle in the process of driving on the heater, will lead to increased fuel consumption, and this is also essential.

Of course not, because everything in between is not the same system and does not cause a loss of fuel consumption.
