    Generally speaking, if the motor vehicle only turns on the heater, the impact on fuel consumption will not be, or almost negligible, but it will also have an impact on fuel consumption more or less.

    It is not said to increase, but when the temperature of the cold car is not enough, it will increase, and the engine temperature must reach about 90 to not consume fuel, and the cold car will increase the amount of fuel injection, which will indirectly increase fuel consumption.

    The car air conditioner heater is heated by using the waste heat of the engine, and when it is turned on, it only increases the power consumption by blowing the fan, which has almost no impact on fuel consumption.

    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 increased fuel consumption. However, when the water temperature reaches the specified temperature and continues to run at high speed, the heating heat blown by the heater 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 heater is not turned on, this part of the energy will be dissipated into the air through the cooling system such as the water tank and heat sink with the help of antifreeze circulation, so the impact of the heater on fuel consumption is basically negligible. However, if you turn on the heater when the car is cold, you will not get the heater and the warm-up time will be extended, so generally do not turn on the heater switch before the water temperature rises. If the air conditioner is started and the compressor works, it will definitely consume fuel, because the power consumption of the air conditioner during heating is higher than that during cooling, it is more fuel-intensive than turning on the cold air in summer.

    In fact, it does not cost fuel to turn on the heating of the car, because the warm air of the car comes from the engine cooling system of the vehicle, and the cooling system will generate heat when dissipating heat, and the heat will enter the vehicle when the heating is turned on, so as to improve the warmth of the car, so when the heater is turned on, it will not lead to an increase in fuel consumption.

    However, when the car is just started to ignite, if you want to turn on the heater at this time, it may consume some fuel, and if you turn on the heater just after driving, the lubrication inside the engine is insufficient, which will lead to greater friction and increase the load on the engine, so it will be more fuel-intensive at this time.

    When the car is driving in winter, you can drive a distance first, then turn on the heater, and turn on the external circulation, exhaust the cold air in the car to the outside of the car, and then wait for a few minutes, and then turn off the external circulation.

    How the heater is turned on

    1. First of all, the car should be warmed up, and when the temperature of the engine reaches 80 to 90 degrees, the heater should be turned on. Generally speaking, it takes 5 minutes to heat up, and if there is no hot car, turn on the heater, and the air from the air conditioner is not warm.

    2. The circulation mode needs to be set to internal circulation, the temperature in the car can be quickly increased on the grinding, when the car has been in a warm state for a long time, the circulation mode is replaced by external circulation, so that the air in the car can be better purified.

    Both types of circulation need to be cycled to avoid breathing difficulties.

    3. Do not turn on the air conditioner in the idle state for a long time, the fuel consumption of the vehicle will increase, and the engine will produce more carbon deposits. Moreover, if the combustion state of the fuel is not sufficient, there will be more carbon monoxide production, and if the carbon monoxide concentration is too high, the occupants of the car are prone to poisoning.

    4. The temperature of the air conditioner needs to be adjusted, and the temperature is more suitable between 24 and 26 degrees Celsius, so that it will not feel too hot or too cold.

    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.

    When the car engine is running, there is no electricity in the strict sense, a good fuel vehicle 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 be heat exchanged 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 always monitor and adjust it through the thermostat to maintain the engine at the optimal operating 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 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.

    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.

    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.

    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.

    <> "High fuel consumption caused by heater?

    We all know that the air conditioner in the car will lead to an increase in fuel consumption, so will it increase the burden of fuel consumption if there is no hidden wind in winter?

    The principle of warm air is actually that when the cooling system of the engine dissipates heat from the engine, the heat dispersed by the fan is sent into the car, and the warm air is formed. Usually, when you are not using the heater, the fan is not turned on, and the hot air outlet is also closed, and the heat emitted will be directly dissipated into the atmosphere. Therefore, the car's heater is theoretically reused as a waste and does not increase fuel consumption.

    But in daily driving, I often feel that after turning on the heater, the fuel consumption also goes up, what is going on?

    A tricky thing that many people will encounter when driving in winter is fogging up the front glass of the car. In order to allow the fog on the glass to dissipate quickly, the owner will turn on the A C switch. The A C button is actually the switch of the air conditioning compressor, and turning on the air conditioning compressor is equivalent to opening a high energy consumption accessory.

    It needs an engine to power it, which means it needs to consume gasoline, which increases its daily fuel consumption.

    In addition to this, many car owners have experienced the illusion of entering the refrigerator as soon as they get into the car in winter. Because most of the cars are parked in garages or places with low outdoor temperatures, and there is no heat source for a long time, resulting in low temperature in the car, some car owners will choose to turn on the heater before driving, go to have breakfast and wait for the car to warm up before driving. And when starting cold, the engine also has a warm-up process.

    At this time, if you turn on the heater as soon as you get into the car, the engine will receive a signal to increase the number of revolutions to maintain the temperature, and it is very fuel-intensive to idle and rev high. The engine is injected with thick oil, and it will increase carbon deposits, which will hurt the engine. Only when the water temperature comes up, the excess engine heat will not increase fuel consumption.

    That is to say, if you turn on the heater in the normal order, it will not produce too much fuel consumption, but if you idle in place for a long time or keep the A C switch on, the fuel consumption will increase.

    Although driving a vehicle in winter does not have to be affected by the same cold wind as an electric vehicle, it is also necessary to pay attention to keeping warm, and it is also necessary to turn on the warm air for the car according to your own situation. Improving the driving environment of the vehicle type hall, improving the comfort of the owner, and also reducing the occurrence of accidents.

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.
