Does it consume fuel when turning on the heater, and how to use the heater correctly?

Turning on the heater sometimes costs oil, sometimes it does not consume oil, which is mainly judged by the temperature of the engine.

If the engine temperature is low and does not reach the appropriate temperature for the car to operate, turning on the heater at this time is to increase fuel consumption. Because when the car does not reach the right temperature, the car computer will automatically increase the amount of fuel injected in order to quickly heat up the vehicle. A striking example of this is the high idle speed of the vehicle when it is started coldly in winter.

This is the reason why the computer automatically increases the amount of fuel injected.

After forcibly turning on the heater, the heating rate of the vehicle will decrease, which will lead to a longer warm-up time and an increase in fuel consumption.

If the engine temperature reaches the normal temperature, turning on the heater at this time will not have much impact on fuel consumption. Because, at this time, the heat of the engine is already an excess accessory. If you don't use a fan to blow into the cab, it will also be emitted through the radiator.

Therefore, from the perspective of fuel consumption and engine protection, the heater should be turned on after the engine reaches the right temperature.

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.

The car heater is heated by the buried heat transfer of the engine coolant hopper, so there is no additional fuel consumption! When the water temperature comes up, you can get a warm air. Applying a warm air in advance before the water temperature button pin dust comes up will prolong the time for the water temperature to rise.

First understand how car heaters work:

1.When the coolant temperature is high, it flows through the heat exchanger in the heating system, and the blower exchanges the air with the engine coolant, and finally the heated air is sent into the car through the air outlets. To put it simply, the heat of the engine coolant does not need to be used in vain, and the car heater is heated by the heat transfer of the engine coolant, so there is no additional fuel consumption!

How to turn on the heater if the car does not turn on the air conditioner:

Do not turn on the air conditioner in a hurry after the car starts, wait until the engine water temperature gauge pointer reaches the middle position, and then turn on the heater.

A C is the abbreviation of air condition, it is the switch of the empty draft meditation refrigeration, and there is no need to turn on a c when turning on the heater.

The temperature of the warm air can be controlled at about 18 25. First, this is the most comfortable temperature for the human body, and secondly, if the temperature is high, it will increase fuel consumption.

If you feel that the air in the car is a little turbid and the oxygen content is decreasing, you can adjust it to the external circulation.

Prolonged use of air conditioners increases the burden on the condenser and causes wear and tear on the refrigeration system. Therefore, the air conditioner can be turned off at the right time, let it "take a break", and turn it on again after a while.

The air conditioner should be turned off three to five minutes before the engine is stopped, which can not only reduce fuel consumption, but also avoid odors caused by the air conditioner. If the engine is turned off without turning off the air conditioner, it will cause mold to multiply in the air conditioner, and when it starts again, the vehicle will ignite with the pressure of the air conditioner starting, which will cause damage to the engine due to the high load.

The car heater turned on is theoretically fuel-free. 1. In the process of turning on the heater, the coolant heat energy in the engine is used to increase the temperature and circulate it into the small water tank; 2. When the blower infiltration machine is running, the heat energy in the small water tank is blown into the car; 3. The load is very small in comparison; 4. The fuel consumption of the car without heater pants is slightly different, but it is almost negligible. Car heating refers to the cooling system of the engine, and a small fan introduces heat energy into the car during the process of exhausting the heat from the engine.

During the process of turning off the heat, the fan stops running, and when the hot air outlet is closed, some of the heat energy is dispersed into the empty air. Therefore, car heating should be a waste reuse and will not consume Tremor Ridge oil. Since warm air does not require the compressor to run, turning it on wastes the power consumption of the compressor.

In addition, it is not advisable to turn on the heater immediately when you are just starting out. It generally takes about 2 minutes to wait for the car engine to heat up to the normal working temperature.

Yes, it will lead to increased fuel consumption.

Many car owners will turn on the heater immediately after getting into the car, but when the engine is just started, the temperature of the water tank is very low, and suddenly turning on the heater will not only increase the load of the engine, but also delay the time when the water temperature rises, which will naturally lead to an increase in fuel consumption and the temperature in the car is not warm.

The correct approach should be to start the engine to drive normally, preheat for a period of time or rent a room, wait for the water temperature gauge temperature pointer to the middle position, and then turn on the heater, and at the same time set the air circulation to external circulation, first let the cold air out of the car, and then adjust to the internal circulation after 2-3 minutes, so that the car will warm up after a while, and it will not cause a burden on the engine.

In addition, when the heater is turned on, the A C button does not need to be pressed, because pressing it means that the compressor has started to work, which naturally increases fuel consumption. The car cold air and warm air are two systems, the warm air is generated by the heat and heat cycle generated by the car's own engine, there is no need to use the compressor to work and consume fuel, we just need to turn the temperature up and turn on the air conditioning switch.

There will be a slight increase in fuel consumption when the car is turned on the heater, which is basically negligible. Because our hot air utilizes the extra heat of the engine, it should be exhausted into the atmosphere even if we don't use it, so there is no difference between using it and not using it. But when we turn on the warm air, we have to turn on the blower, electricity, and we need the energy of gasoline to convert silver, so the fuel consumption will be a little more.

But in a particular case, if you're in the northeast direction of minus 30 degrees Celsius, and you want to maintain its normal operating temperature, it needs to inject more fuel instead of extra heat. At this point, the use of hot air results in a slight increase in fuel consumption.

Don't turn on the heating as soon as you get in the car. We shouldn't turn on the heating when we get in the car. Instead, we should wait for the car to start for a few minutes and then turn on the heating once all the parts in the car start to harmonize.

Since low temperatures inhibit the performance of the engine and other components, turning on the heater at this time will undoubtedly increase the operating burden of the car. Fuel consumption will naturally become higher. The temperature of long-term low-speed operation of the engine is generally about 80-90 degrees, so if it cannot reach this temperature, the amount of fuel injection will naturally increase, so the long-term low-speed operation combined with warm air will take away a certain amount of heat, but it will also lead to an increase in fuel consumption, but the warm air has little effect on fuel consumption at high speed.

The correct thing to do should be to start the warm-up, such as pointing the temperature pointer to the middle position, then turn on the heater, and set the air circulation to the outer circulation, wait for 2 3 minutes until the cold air in the car is discharged from the car, then you can set the air circulation to the inner circulation. If the heating is used, the state banquet does not need to turn on the AC switch. The air conditioner button is the key to turning on the air conditioner and refrigeration of the car.

Press this button and the compressor starts working and starts blowing the cold air. Many car owners turn the heating up to the maximum and then turn on the AC button, which, on the contrary, consumes the fuel of the car and slows it down.

With the heating on and the car in a confined space, it is easy for bacteria to grow. Smoking in a car is harmful to health, and second-hand smoke is inhaled. Amine and nicotine fumes will stick to the surface of the evaporator, if the air conditioner is not used frequently, and in cloudy and rainy conditions, bacteria will spread on the surface of the evaporator, and when the air conditioner is turned on, it will cause air pollution in the car.

No fuel consumption; If you want to turn on the heater correctly, you need to press the brake Lingnian pedal, then start the engine and wait until the water temperature reaches 90, unscrew the wind speed adjustment button, and rotate to the rightmost gear.

I don't think it consumes fuel, you first have to switch to the internal circulation mode, then turn on the car's air conditioner, and turn the knob to the heating mode.

The car heats up without using any fuel. Because the heating is actually the heat generated by the engine, if the owner does not use the heating in the summer, the heating is cooled and circulated through the water tank. If heating is used in winter, part of the heat generated by the engine is cooled down by the water tank to dissipate heat from the engine, and the other part enters the interior of the car through the warm air channel.

Therefore, heating in winter will not increase the fuel consumption of the vehicle. The so-called increase in fuel consumption is because the engine reaches the normal operating temperature longer than spring, summer and autumn, which will naturally increase fuel consumption, but it has nothing to do with turning on the heater.

In general, there are three situations for turning on the heater in winter:

1. Turn on the heater after getting in the car.

This practice will increase fuel consumption, because the engine needs to work at a suitable temperature, in the case of low outdoor temperature in winter, it is impossible to reach the most suitable working temperature of the engine when the vehicle is just started, so the vehicle will increase the amount of fuel injection slag to increase the temperature of the engine, if the heater is turned on immediately after getting on the car, then it will inevitably increase the burden of the engine, and fuel consumption will also rise sharply.

2. Turn on the heater after a period of time.

In this case, the impact on fuel consumption is minimal, because the warm air in winter is directly from the heat brought by the engine, after the vehicle is driven for a period of time, the engine reaches the appropriate working temperature, and the remaining heat is surplus, then the impact of the warm air on fuel consumption is relatively small.

3. Start the compressor while turning on the heater, which is the A C button in the car. (Photo by Li Lingyan) @2019
