If you start the car and turn on the heater directly, will it really increase fuel consumption and c

Many friends will turn on the heater first after getting in the car, and even some friends do not turn off the heater before turning off the heater, so turning on the heater in the cold car state will really lead to increased engine fuel consumption and serious carbon deposits? There are many such sayings on the Internet, and their theoretical basis is that turning on the heater in the cold car state will affect the coolant heating in the radiator, resulting in the engine heating up slowly, which in turn leads to an increase in engine fuel consumption and is more likely to produce carbon deposits. Is that really the case?

Let's give you an analysis.

<> must be able to think of the masters of the above pseudo-theories, and they must not know that there is another thing called "thermostat" in the engine cooling system, the function of the thermostat is to control the size of the cooling system, the small cycle is to heat up the engine faster, the large cycle prevents the engine from overheating, when the cold car starts, in order to heat up the engine faster, the thermostat is in a closed state, the cooling system is in a small circulation, and the coolant returns to the engine through the water pump after coming out of the engine; When the water temperature reaches about 70°, the thermostat is slowly opened, the engine cooling system is in large circulation, and the coolant enters the radiator through the water pump after coming out of the engine, and re-enters the engine after the radiator dissipates heat.

So the question is, the car heater relies on the blower to blow the heat of the engine radiator into the car, and when the coolant has not entered the radiator, how can turning on the blower affect the engine heating? It does not affect the engine heating, it will not affect the fuel consumption of the car when the car is cold, and it will not increase the carbon deposit of the engine, when the water temperature is 70, the coolant begins to enter the radiator to circulate, and the blower can blow the heat of the radiator into the car, and the air outlet can have hot air.

After the water temperature reaches 70, the vehicle is hot-up, and the engine parts have been lubricated enough, and the engine will not heat up slowly due to turning on the heater, which will affect the fuel consumption of the car and increase carbon deposits.

The remarks on the Internet that you can't turn on the heater directly when you get on the car, which will lead to an increase in engine fuel consumption and serious carbon deposition, are all unscientific, the thermostat is not opened, the coolant does not enter the radiator, and the cold air blows into the car, which will not affect the engine heating up at all, and the only effect is that the blower will waste a little bit of power, and the cold wind will feel colder after blowing on the body.

If you start the car and turn on the heater directly, will it really increase fuel consumption and carbon deposits? There are too many pseudo-theories online

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, 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 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.

When the car engine is running, there is no electricity in the strict sense, a good fuel car Qi digging mold is driven by the engine to generate electricity, and at this time all the electricity used by the generator is powered by the generator, so the fuel vehicle in the start does not cost electricity, only fuel.

The reason why the air conditioning system of a gasoline vehicle is able to output warm air is that the engine generates heat energy while it is running.

The heat energy generated by the operation of the engine will be transferred to the engine coolant, so that the temperature of the engine coolant rises, and the coolant will flow through the heat exchanger in the heating system after the air conditioner turns on the warm air, and there will be the air in the car sent by the blower, and the air sent will exchange heat with the engine coolant, and the heated air will be blown back into the car through the blower, so that the air temperature in the car will rise.

Whether it is more fuel-efficient to turn on the heater in winter is analyzed in two situations:

1. Heating in areas with low ambient temperature in winter will not cost more fuel; The engine of a gasoline vehicle has an efficient operating temperature, and the engine computer will monitor it at all times and adjust it through the thermostat to maintain the engine at the optimal working temperature. The temperature is not low, and the excess heat energy from the engine work is enough to maintain the temperature and heating system**, so it does not consume more fuel.

2. In winter, heating in areas with very low ambient temperature will cost more oil; In the same way, if the excess heat energy after the engine has done work is not enough to maintain its own efficient working temperature, turning on the air conditioner to heat will inevitably need to burn more fuel to provide heat energy, so this situation will be more fuel-intensive.

The car heater will increase fuel consumption, the power consumption of the heater will increase the engine load, the influence of the heater on the water temperature, will also increase the engine fuel consumption, in addition, the fuel consumption of the car in winter is too high, and the atomization effect of gasoline also has a great impact, the car is not recommended to turn on the heater just start, because it is meaningless to open the heater at this time, and it will not produce heat.

Car heaters and air conditioners work on completely different principles. The car heater mainly comes from the heat of the water tank, which uses the circulating water of the engine to generate heat, and then blows out the hot air through the blower, which does not require fuel at all. Even if the heater is not turned on while driving, this heat will be discharged from the car and wasted.

Therefore, the heater can be turned on as much as you like in winter, without considering fuel consumption.

1. Usually after refueling to jump gun, the refueler always has to continue to refuel the tank in order to make up a whole number. In fact, this method is not very correct, when the gas station is full of fuel, after the first jump gun, due to the amount is not complete, the gas station staff will make a second jump gun to round the amount. At this time, because the fuel tank is full, there will be an oil leak if the gun is jumped again.

2. Because gasoline is more volatile than water, the oil in the fuel tank will change from liquid to gaseous when it encounters heat (sunlight exposure, heat generated by electric gasoline pump), which increases the pressure in the fuel tank. It is not allowed to add it to the jump gun, which is to leave room for the existence of gasoline vapor after gasoline evaporates.

3 Let's talk about the situation of too much refueling, which is also the most common problem in our daily life. If you add too much oil, it will expand and spill due to temperature changes, which is easy to cause the risk of spontaneous combustion of the vehicle. At the same time, too much refueling will cause damage to the canister, and the excess gasoline will flow to the inside of the canister with the fuel vapor to form damage.

When the canister is damaged, it cannot filter the gasoline vapor, and gasoline will be passed into the body. Because gasoline has a variety of harmful substances, long-term exposure to gasoline vapor is harmful to health and even cancer.

4. There is also a situation, when refueling too fast, the air inside is compressed and suddenly sprayed out, reduce the flow when it is almost full, and wait for the bubbles to slowly bubble up before adding, the fuel tank will not be filled with fuel.

5. Filling overflow is harmful to the vehicle, when the oil is too full, the volume expansion of gasoline will break the fuel tank, so when the car is designed, there are vents on it, if the refueling is too full, it will pass through the vents and spill oil to the outside, and the gasoline is particularly volatile, and it will burn instantly once it encounters an open flame. Causing irreparable damage. Secondly, it is easy to clog the ventilation hole when it is filled with spilled oil.

Once the vent is blocked, negative pressure will be generated in the tank, resulting in poor oil supply or even no oil supply. The engine does not catch fire after the car is just refueled, or the car is driven at high speed, and the spilled oil is filled and causes damage to the car parts. Filling up too much gasoline itself will definitely increase the overall weight of the car and increase fuel consumption.

In addition, if it is too full, it is easy to cause gasoline liquid to enter the pipeline, which not only causes harm to the carbon canister, but also flows into the airway along the pipeline, causing the spark plug to work out of order, and even causing the vehicle to fail to start.

<> "As we enter winter, the temperature is getting colder and colder. Every morning, when I first sit in the car, I can't wait to turn on the air conditioner to the maximum. If there is no warm wind, you can only shiver there for the whole winter.

However, many more economical car owners are worried that turning on the heater will increase the fuel consumption of the car, so they would rather freeze than turn on the heater. So in the cold winter season, will it consume fuel when driving with the heater?

As we all know, when the car turns on the air conditioner in summer, it is a big waste of fuel, because when we turn on the air conditioner, the air conditioning compressor will start to run, and in order to drive the operation of the compressor, it is necessary to increase the power of the engine to achieve, the engine load increases, and the fuel consumption will naturally go up.

However, the principle of heating the car air conditioner in winter is to let the coolant of the engine flow into the heat exchanger, and then the heated air is blown into the car by the blower, that is to say, the hot air blown by the car air conditioner comes from the heat generated by the engine, so the car heats up in winter is basically fuel-free. Many car owners feel that turning on the heater costs fuel because the A C button is turned on when the heater is turned on, so the fuel consumption will increase.

After talking about the problem of whether it costs fuel to turn on the heater in the car in winter, let's talk about a few problems that should be paid attention to when the car heats up in winter. First of all, the cold car can not be turned on immediately after starting, because the winter is very cold, many car owners will turn on the heater as soon as they get in the car to heat. However, this will not achieve the effect of heating, but also increase the fuel consumption of the car.

Because when the car is just started, the cooling water temperature of the engine is not enough to meet the heat required by the heater, so don't rush to turn on the heater immediately after starting the car.

Secondly, when you turn on the heater, you must control the temperature, and the general temperature setting is 20 to 25 is the most comfortable, and it can also achieve a good heating effect. If the temperature of the heater is too high and the temperature difference between the inside and outside of the car is too large, getting out of the car can easily lead to a cold. In addition, when you turn on the heater, do not blow the air conditioner directly on your face, which will cause physical discomfort for a long time, and it will also lead to dryness.

Therefore, when you blow the air conditioner and warm air, it is best to adjust the wind direction to the position under your feet, and you can also get a good heating effect.

The third point is that the heater just mentioned should not turn on the A C button, the car air conditioner heater uses the heat cycle inside the car, and there is no need to start the compressor, so there is no need to press the A C switch. Finally, when you turn on the heater, you should pay attention to not turning on the heater for a long time when you stop in place and rest. Because blowing warm air in a confined space can easily lead to carbon monoxide poisoning, it is best to open the windows to keep the air circulating in the car when you stop for a long time to rest.

It doesn't cost fuel to turn on the car heater, because the heating in the car is provided by the car's cooling system, regardless of the speed and power of the engine. In winter, the water temperature of the engine is used to heat the warm air, so when the warm air is used in winter, the empty compressor does not work, and the fuel consumption will not increase.

The car heats up without using any fuel. Because the generation of heating is actually the heat generated by the engine.

Of course, it will also be a function of the car.

The fuel consumption of turning on the heater is completely negligible. The warm air mainly comes from the heat of the water tank, which is the heat generated by circulating water in the engine and then blown out by the blower.

How car heaters work:

1.At present, the form of warm air on the car is mainly water heating, its heat source comes from the engine coolant, when the coolant temperature is high, it lacks the shed to flow through the heat exchanger in the heating system, and the blower will heat exchange 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 air conditioner 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, the engine may need to do additional power to generate heat, which increases 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.

This can not only reduce oil consumption, but also avoid odors caused by air conditioners. 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.
