Many cars turn into insatiable "monsters" in winter. The driver looks at the fuel gauge, his heart contracts, and his wallet vibrates plaintively. How can you reduce fuel consumption in winter?

Increase the "gluttony" of the car in winter

Morning, severe frost. The car interior is cold and uncomfortable at all. The driver turns on the ignition and the engine responds strong vibration... It is then that the realization comes that he is currently working for wear and tear. It is under this circumstance that the motorist comes to understand that it is time to install a "signal" with auto start, or some other device for heating the engine. But if these plans are implemented, then the fuel consumption will increase.

But the gluttony of cars in winter also increases for other reasons.

In severe frost, the oil becomes more viscous. That is why the engine needs more time for the unit components to warm up better and begin to move without unnecessary friction.

In order to achieve the optimum temperature, the motor needs 15-20 minutes. The fact is that the stronger the frost, the longer it will take to warm up.

So, the motorist faces two problems: what to do so that the engine does not cool down quickly, and how to reduce the viscosity of the engine oil?

Solving the problem of fuel consumption in winter

The simplest and effective method- content vehicle v good condition, because even the slightest malfunction can cause the machine "zhor".

Take, for example, sensors that signal what position they are in. throttle... After all, the "brains" of the machine understand that something is not going as it should. And therefore, just in case, there is a larger than necessary supply of fuel.

Another rule that should not be neglected is the use of engine oil that is appropriate for the season.

With the arrival of cold weather, the oil needs to be changed. It is not worth saving on it. If you fill in the "fired" oil, then it can be viscous and complicate not only the operation of the engine, but also increase the consumption of "fuel".

You should not ignore the various additives that can reduce the friction force in the unit and transmission. Most of all, this is important for diesel engine- because the quality of diesel fuel in our country is not up to par.

Lubricating additives, which do well with the "kerosene" trail, have shown themselves excellently, because little-known gas stations very often sin in this. It is advisable to use them after every 3-4 refueling of the vehicle.

For the off-season, antigels are good, because at this time you can often "run into" the summer diesel fuel at the gas station.

So it is better to fill them after each refueling. They will not be worse, but the chances of starting the engine on a frosty morning will increase.

Some motorists do chip tuning. With its help, they try to "inspire" the engine that "water with a smell" will be enough for it to work properly.

You will have to pay about three to four thousand for such a procedure. But it depends on the age of the car and its model. If you drive carefully, the firmware will save 10-15% of fuel, i.e. this can be achieved without chip tuning. For those who like to drive such a procedure, it is useless to do.

You can cover the engine with a car blanket in winter. But it retains heat for no more than 5-6 hours. If the car is not left for a long time, then there is no need to warm up the engine.

Causes of increased fuel consumption in the winter season

Winter brings with it not only the New Year and Christmas holidays, it is a difficult time for drivers in all respects, and this affects the wallet due to the increased fuel consumption.

Small car drivers may not notice this difference if they prefer to use their car as little as possible in winter, but those people who really spend a lot of time behind the wheel may see that the engine has begun to consume more fuel.

What is the reason for the increased fuel consumption in winter? There are many reasons. Let's name the most basic ones.

First, starting on a cold engine, according to experts, is tantamount to a mileage of 800 kilometers - so badly it affects the engine. To avoid such negative consequences, the engine needs to be warmed up at least a little, that is, left to idle for a while.

If the car is parked in a heated garage, then you are in luck, but those people who leave their cars under the windows of their houses on the street have to wait at least ten minutes until the temperature in the engine rises.

It is so difficult to start a car in winter, because all liquids thicken and become more viscous, in addition, the battery can be pretty discharged overnight. Also, due to the fact that the intake manifold is cold, the air does not mix well with the fuel and does not ignite.

If you do not have a garage, then bring the battery into the warmth at least for the night, and in the morning you can pour boiling water over the collector. Do not start the engine immediately, just turn on the ignition and light the near and high beam to overclock the battery. You can also use special additives, such as "Cold Start" or "Quick Start", they contain essential substances and the car starts up much faster. But all the same, due to the morning warm-up of the engine, the consumption increases to 20 percent.

(function (w, d, n, s, t) (w [n] = w [n] ||; w [n] .push (function () (Ya.Context.AdvManager.render ((blockId: "RA -136785-3 ", renderTo:" yandex_rtb_R-A-136785-3 ", async: true));)); t = d.getElementsByTagName (" script "); s = d.createElement (" script "); s .type = "text / javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore (s, t);)) (this , this.document, "yandexContextAsyncCallbacks");

Secondly, even if you manage to start the engine, you cannot drive on snow drifts at the same speeds as in summer. The overall speed decreases in winter, and as you know, the most optimal fuel consumption occurs at speeds of 80-90 km / h in high gears. When the road looks like an ice arena, then you have to move very carefully, and especially outside the city, where road services do not always cope with their work.

Thirdly, the consumption of gasoline also increases due to the quality of the road surface. Even if you have installed a good winter tires, then all the same tires have to take away more slush and "porridge", all this sticks to the wheels and creates rolling resistance.

Also, many drivers reduce by winter period pressure in the tires, citing the fact that thus increasing stability. This is really true, but at the same time the consumption increases - by 3-5 percent.

Energy load is also an important factor. After all, in winter you want the car to be warm, the heating is constantly on. An air conditioner helps to fight high humidity in the cabin, because when you go into heat from the cold, a lot of moisture evaporates from clothes and body, as a result, glass sweats, condensation appears. Heated seats, rear-view mirrors, rear window- and all this also consumes a lot of energy, hence the increased consumption.

It is necessary to check the technical condition of the engine even before the onset of cold weather. Worn pistons and piston rings leads to a decrease in compression, power drops, you have to put more pressure on the accelerator, the consumption will increase not only in winter, but even in summer for this reason.

Do not forget also that gasoline decreases in volume at low temperatures. Even if the day is +10, and at night the frost is up to -5 degrees, the volume of gasoline in the tank may drop by several percent.

(function (w, d, n, s, t) (w [n] = w [n] ||; w [n] .push (function () (Ya.Context.AdvManager.render ((blockId: "RA -136785-2 ", renderTo:" yandex_rtb_R-A-136785-2 ", async: true));)); t = d.getElementsByTagName (" script "); s = d.createElement (" script "); s .type = "text / javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore (s, t);)) (this , this.document, "yandexContextAsyncCallbacks");

Let the oilmen and the government promise that fuel prices will not rise until at least the beginning of next year, they have already reached a fairly high level. And in winter, fuel consumption increases significantly. Moreover, contrary to physics, after all, according to the Carnot cycle, with an increase in the temperature difference, the efficiency of the mechanism should increase, and cool air is preferable for the motor, rather than hot. But there are side factors that lead to increased fuel consumption.

Warming up the engine

In winter, we warm up the car longer than in warm weather, although automakers assure that even in subzero temperatures, you can drive immediately after starting the engine. But in order to preserve the resource of the engine and transmission, it is advisable to properly warm up the engine, and then move at low speeds until power unit and the oil in the gearbox does not completely warm up.

Many people install alarms on cars with the ability to remotely start, and some automakers have this in the factory options (for example, the Renault Start system). Naturally, starting the engine from home while we are going to go to the car leads to increased fuel consumption.

Additional energy consumers

Heated seats, heated mirrors, rear, and often windshields waste additional energy, forcing the battery and generator to work under increased load. The switched on stove, and often the air conditioner (to dry the air in the cabin) also increases fuel consumption.

Road conditions and tires

Snow and mud and snow "porridge" lead to slippage and increased resistance when driving. Accordingly, the engine runs at increased load, and this leads to additional fuel consumption. Studded tires also make their contribution: after all, they "bite" into the road surface, which also increases the resistance when driving. A decrease in tire pressure also leads to increased fuel consumption, so it is recommended to check it more often in winter.

Also, traditionally in winter, the average speed drops. And in large cities, closer to the New Year, dead traffic jams begin. Naturally, the engine in this situation spends more fuel.

Additional items in the trunk

Many people increase the number of items carried in the trunk. Here there is an anti-freeze supply, and a shovel, an additional tool. The car becomes heavier, the fuel consumption increases.

Uncleaned car

Many are too lazy to completely clean the car from snow before driving: they wiped off the glass and all right. In addition to the fact that it is unsafe for others, snow adhering to the body also increases fuel consumption, because the car becomes heavier and its aerodynamics change.

Not the most obvious reason

In winter, the air density changes. Moreover, the colder it is, the higher it is. At minus forty degrees, it is 30% more than at plus thirty, and such a range of temperatures is quite real for some regions of Siberia. Accordingly, the higher the air density, the stronger the aerodynamic drag, which means the car needs more fuel to move at the same speed as in summer.

• Winter is a special time for the car and its owner. Even ardent opponents of various "improvements" are drawn to shops for

Have you noticed that the car consumes a lot of fuel in winter and at other times of the year? it important point negatively affecting the budget. He worries vehicle owners who don't want to waste their money. If you have such an unpleasant situation, check out our publication. In it we will tell you why the problem appears and how to reduce fuel consumption using effective methods... After reading the article, you will learn a lot useful information and you can use it to minimize gasoline losses!

TOP-5 reasons for fuel consumption

Let's take a look at the reasons why a vehicle consumes a lot of fuel during the winter. These include:

1. Cooling of technical fluids and cold engine- after starting the car, you need to wait until the operating temperature for the trip is created. During this time, the vehicle consumes a lot of fuel.
2. The operation of the stove in the cabin, heated seats and windshield- to solve such problems requires a lot of energy. Therefore, the engine consumes an order of magnitude more gasoline and diesel fuel;
3. Decrease in tire pressure - when the temperature is below zero, the pressure decreases. In this case, the rolling resistance is increased.
4. Driving on snow-covered snowdrifts, car slipping - snow creates additional resistance that must be overcome. This takes a lot of energy. She is compensated increased consumption gasoline.
5. Decrease in driving speed by slippery road- such an indicator will certainly affect the budget.

Fuel economy is an issue of interest to drivers not only in winter. At other times of the year, the vehicle can also consume a lot of gasoline. What is the reason for this? The main objective reasons include late ignition, incorrect spark plug gaps, wear of the cylinder-piston group, unregulated wheel alignment, dirty fuel injectors, clogged air filter. The generator is also capable of absorbing some of the fuel consumption. An increase in the load on the generator may result in a faulty battery. Considering that a faulty starter can completely exhaust the battery life. By using you can eliminate the malfunction of the units.

There are also subjective factors that raise the question of how to reduce fuel consumption. These include overloading the car above the norm, installing spoilers and body kits, moving at high speed with open windows, long-term operation of the climate and acoustic systems.

How to reduce fuel consumption in winter

What fuel consumption is considered acceptable? It is different for each type of vehicle. This indicator is calculated on the basis of the base rate, taking into account operational, weather, road factors.

How to save gas and diesel fuel in winter? We have a detailed answer to this question:

• before winter starts, contact service center... Let the experts adjust the wheel alignment;
• check the tire pressure regularly - this will help to avoid unnecessary cash costs;
• get rid of excess weight - free the trunk of everything that you do not need;
• drive along the track at a constant speed - avoid aggressive driving;
• use a special engine insulation - such a product is made of refractory materials. With its help, the time for warming up the engine in frost is significantly reduced.

And one more thing: periodically contact the service station in order to check technical condition vehicle. This means timely replacement air filter, cleaning the injectors from contamination, elimination of malfunctions of the gas distribution mechanism. You also need to use oils and fluids that are recommended by the car manufacturer. When you take into account all the nuances, saving fuel in winter and at other times of the year will not be a difficult problem.

Why does the consumption increase in winter?
For most motorists, fuel economy is the most pressing issue.
The cost of gasoline and diesel, unfortunately, is constantly growing, and due to the active operation of the vehicle, fuel consumption remains high. In order to somehow reduce it, many drivers reduce the number of trips, especially in winter.
But if you wish, with just a slight change in your habits, you can cut your fuel costs by ten percent. What has the greatest impact on a car's fuel consumption?
Climatic conditions. In cold weather, fuel consumption is much higher than when the thermometer is above zero. This is explained by the fact that the engine reaches operating temperature rather slowly in cold weather. All this time on-board computer tries to help him by feeding increased doses of fuel into the cylinders.
If someone thinks that we cannot influence the engine warm-up rate, then he is mistaken. It is known that with an additional load of the required temperature, the unit will reach faster than working on Idling... Therefore, you should start moving as quickly as possible. It is enough just to wait for the moment when the revolutions will stop floating and you can slowly get under way, without waiting for the moment when the arrow of the coolant temperature indicator will move from a dead center.
Use of comfort equipment. In cold weather, many motorists do not think about how to reduce fuel consumption and help the engine get into a working rhythm, but about ensuring their own comfort. Sitting behind the wheel, drivers immediately turn on the stove, hoping to warm up the interior. But since the motor has not yet had time to warm up, there is nowhere for the flow of warm air to come from, so it is not advisable to use heating in this case.
Few people think about the fact that during operation, the stove takes some of the heat from the engine, thereby preventing it from reaching operating temperature and taking away some of the power. As in the first case, "brains" come to the aid of the unit, believing that more fuel needs to be supplied to the cylinders. Therefore, try to turn on the heating of the passenger compartment only after the engine temperature reaches 80-90 degrees. Or at least 40 ° C.
Driving style. If we can only have an indirect effect on the operation of the engine, then fuel consumption while driving depends solely on the driver. It is not hard to guess that supporters smooth ride visit petrol stations less often than those who are used to aggression. Therefore, those who monitor their expenses do not hurt to learn how to control their emotions and refrain from unmotivated risks, which are always associated with the so-called. sporty riding style.
Reduced fuel consumption is facilitated by fewer stops along the way. Learn to predict road conditions, refrain from routes running on busy highways, as well as secondary roads, where snowblowers rarely look. While driving, watch the tachometer readings and try to keep them around 2000 rpm.
