Summer and winter fuel consumption: difference, reasons, reduced fuel consumption. Why winter fuel consumption is more? Plus video version How much increases flow in winter

Surely every motorist is aware that winter is a real test for any machine. This is especially true when the temperature range is reduced below 10-15 ° C. Low temperatures can not only lead to increased wear of the power unit during a cold start, but also entail an increase in consumption by a fuel car, an average of up to 15% compared to the plus temperatures .

Increased fuel consumption in the winter period of the year, directly depends on some factors:

Increasing the consumption of fuel in winter, begins from the moment the power unit is launched, and the ambient temperature below, the more gasoline consumption increases. This is due to the fact that at lower temperatures, the time of engine warming increases and as a result, the growth of fuel consumption. And, as it is known that the consumption of gasoline at idle is no less than during the movement.

How to be in the current situation? After all, not to warm the car in the winter before the trip will cost more. This is due to the fact that the oil in the power unit in the winter is much thickening and if you start moving without warming up, it will lead to a rapid wear of the engine due to poor-quality lubricant, moving nodes. Based on this, no matter how much you want to save on gasoline, you still have to spend time to warm the car, as you buy spare parts and engine repair itself will cost much more expensive.

Naturally, this can be avoided, saving its iron horse in a heated room or installing the engine premises electrical system. This will not only help save fuel, but also to extend the operational resource of the power unit.

The next important factor that affects the fuel consumption is to control the car on snow-covered roads. Snow cover formed on the surface of the roadway creates an additional barrier, to overcome which a power unit will need more power and as a result, an increase in gasoline consumption.

The appetite of the Iron horse will increase even more if the snow on the road becomes wet, which leads to his sticking in the fears and twisted wheels. Therefore, when driving on a wet snow, it is necessary to stop from time to time and sneak snow from the pikest arches.

However, the maximum consumption of fuel occurs when the car is hit in a snowy snowdrift. After all, to depart out of the current situation, the motorist may need a long time, to stop on the spot, trying to leave a snowdrift, and this can lead to a single extra liter of gasoline.

Also on the consumption of fuel, even if it does not significantly affect the constantly turned on the heating of the cabin and it will not come out with it. After all, there will be no automotive to freeze in the car for saving several liters of gasoline.

Well, another factor directly affecting fuel consumption, both in the winter and summer, is a ride style. To save fuel, the most appropriately smooth and measured movement without unnecessary jerks and sharp braking.

Summer and winter trips by car - "Two big differences". One of the sides of this difference is the increased consumption of fuel by car in winter conditions. It is worth more closely to consider the reasons for these additional expenses and ways to reduce unwanted spending on fuel.

Causes of increased fuel consumption in winter

Engine heating and lubrication systems

In winter, it takes more time to achieve engine operating temperature. An extra work time at idle leads to increased fuel consumption . This is especially true for cars with carburetor engines. The desire to save fuel and start moving, without waiting for the temperature to increase the working values, leads to the fact that the motor will "sneeze", the car will move the jerks.

Modern cars do not require long-term engine heating . It is enough for him to work at idle no more than one minute - and you can start moving. But I will still have to spend a minute, and the additional fuel consumption will be.

If the machine is used in winter from the case of the case, then the losses for warming will not have a significant effect. But for cars used daily, unnecessary fuel for the engine warming twice a day (before going to work, and before returning from work) - a sufficiently solid gain to total costs.

Yes, and it is necessary to warm up not only the engine. The oil in the transmission and lubricant in the bearing on the frost become more dense, and the time is necessary for their warming up and achieving conditioning condition. And during this time you will have to overcome additional resistance and spend on this additional fuel.

For different estimates, additional fuel consumption for engine heating and all systems can reach 5 - 10%

Of course, this averaged values \u200b\u200bare precise losses depend on weather conditions and car brand.

Worsening Road Conditions

Riding in winter roads requires an additional effort from the machine, which requires additional fuel. Here are the main reasons, worsening the movement of the car in winter:

• Clutch tires with expensive in winter conditions worse than in summer. Even in the ramble snow, it is harder to move more difficult than on asphalt. This is when driving without special obstacles. But additional problems create and slip on slippery sites, especially when touching from the spot. But it is necessary to ride and immediately after the snowfall, when the snow is not yet tumped. Elevated gasoline consumption with difficulty movement is obvious.
• Hit into drift or drifts lead to engine operation at elevated circulation. And the departure of the parked car after rich snowfall is generally a separate song. Only to get out of the parking snowdrift, sometimes you have to spend fuel as a journey of the average duration
• When moving in winter country roads It is necessary to abide care and ride with low (compared to summer conditions) speed . Therefore, it is not always possible to withstand the most economical mode of movement.
• Traffic jams. Of course, they arise in the summer, and the statistics argue that in the summer there are even more. But in the winter they are larger. Due to snowfall after snowfall, in many ways, it is possible to move only in one row in each direction. And any accident often leads not to restriction, but almost to the cessation of traffic on this road.

Increase power consumption

Few people will be drunk to ride in winter without inclusive stove . In decent frost, the cabin heater has to constantly work at full capacity. Besides the cabin, you have to select the rear window and mirrors separately. And you can not get anywhere - this is the issue of security. And the energy of all heaters provides the engine, spending on this extra liter of gasoline.

Starting the engine in the cold often proceeds not as fast and easy as in warm weather. As a result, the battery after the winter start is discharged stronger. And with negative temperatures, even a disconnected battery keeps the charge less than warm. AND the generator for recovery of the nominal battery charge is required longer What is also spent fuel.

In little things

• Aerodynamic resistance . Cold air has increased resistance to the car movement. Therefore, in winter, even when moving at optimal speeds, fuel consumption is higher. Under certain conditions, this is not a trifle. In severe frosts (-40 and more), only because of this factor, you can spend gasoline by 10% morethan at summer +20.
• Tire pressure . With a decrease in temperature, tire pressure also decreases. Dependency is about 0.1 atmosphere for every 10 degrees of temperature. Undormatically low pressure leads not only to wear tires, but also to an increase in fuel consumption.
• In carburetor engines with unchanged adjustments at low air temperature the fuel and air mixture changes its characteristics. What affects the operation of the engine and leads to increased fuel consumption.

To achieve the same fuel consumption in summer and winter will not work - too different conditions. And in winter the car will still be spending gasoline more. For example, the official website of the Ministry of Transport of the Russian Federation regulates the increase in winter fuel consumption norms by 5 - 20%. Moreover, the increase of 5% is established for the southern regions, but for the Northern, where the influence of winter is much higher, a 20% surcharge is recommended.

But it is possible to reduce this difference, knowing the causes of its occurrence and, if possible, reducing their influence.

Ways to reduce fuel consumption in winter

Engine

• Reducing the time of warming up the engine at idle is a great contribution to gasoline savings. It is best to start moving immediately after reaching the minimum temperature that does not prevent normal engine operation. When moving on small gears, the engine will warm up to the operating temperature. And all lubricants will also quickly warm up on the go. But also to completely refuse warm-up . Fuel economy will achieve, but the damage to the engine itself may be such that the savings will come side. You need to look for a golden middle. Choosing the idling time is better to focus on the manufacturer's manufacturer's recommendation, as well as on your own experience and feeling your car.
  Best exit - keep the car in the warm garage. At least the morning departure will pass without long warming.

  

• Ocarrow insulation of motor compartment . Modern "blankets" allow you to extend the engine cooling to the outdoor temperature for several hours. In some situations, this will allow you to do without idling.

  

• Special winter oils are gradually replaced by all-season. Pouring special oil in winter, maybe not worth it. And here before the winter season, the oil replacement will be useful for the car . Do not wait for the planned term. New oil will clearly facilitate the operation of the engine.

Tires

• Rebuild rubber under the winter conditions - It is rather a question of security. Savings here are secondary, but it is also present. Yes, the tires with the winter tread are less economical compared to summer. But it is in equal conditions, and when moving along a good road. In winter, conditions are far from equal to summer, and the quality of the road is often very worse. Here, winter tires will block all their "shortcomings" and eventually help save a lot of fuel. Movement on the freshly empty snow, reducing slipping, overcoming the snowdrifts - in this superiority of winter rubber is indisputable.
• It is important to remember O. reduced tire pressure while decreasing temperature . It is impossible to bring pressure to the values \u200b\u200bthat go beyond the norm. In winter, it is better to control this parameter more often.

Energy consumption

Save in winter on heating salon and rear window . The work of these consumers of energy is a harsh necessity, which is not going anywhere. But it is recommended to limit the inclusion of other energy consumers - for example, a sound system. Especially until the complete warming up of the motor and battery charge after starting.

Description of driving

Driving a car in winter differs from summer. Soviets on this topic a lot, but now we are talking about fuel economy.

• We need avoid a sharp start from . The car may just stay on the spot, a cauldron on a similar way to the ice.
• Preferably more responsibly approach the route avoiding traffic . Winter corks are larger, so it is better not to risk, hoping that it will soon dispel.
• Carefully follow the condition of the road, andzibayaya plots on which the car can get stuck or lower .
• Do not park in the first place. A small snowdrift or ice plot can make it difficult to exit.

In little things

• Fallen Snow should be considered not only from car windows, but also from the roof and trunk . Overweight - excess load of the car.
• It is worth thinking - does winter need a top trunk . With long-distance travel, he and in the summer "steals" fuel, and in winter this flow increases.
• Useful conduct the audit of the trunk in front of the winter season . If possible, remove heavy and not very necessary items from it. Trifle, and the car will be easier. It is not necessary to clean the shovel, and even on the contrary - put it in the trunk and carry the whole winter. Do not need - well, well. But sometimes just a few crawl crawls can provide a car trouble-free departure from a problem

Most of the tips on the decrease in unwanted fuel consumption are reduced to one: a car is difficult in winter, and any help to him in hard work is welcomed. Let's help with your car even in trifles - and she will thank you. Including a minor increase in fuel expenses.

Summer and winter fuel consumption: difference, reasons, reduced fuel consumption

Why increase the flow in winter?
For most motorists, the issue of fuel economy is the most relevant.
The cost of gasoline and diesel engine, unfortunately, is constantly growing, and due to the active operation of the vehicle, the fuel flow rate remains high. To somehow reduce it, many drivers reduce the number of trips, especially in the winter.
But if you wish, only a slightly changed your habits, the article on fuel costs can be reduced by ten percent. What does the greatest impact on the consumption of a fuel car?
Climatic conditions. In cold weather, fuel consumption is much higher than when the thermometer bar is above the zero mark. This is explained by the fact that the engine in the frost reaches the operating temperature quite slowly. All this time, the on-board computer is trying to help him, feeding high doses of fuel in cylinders.
If someone believes that we cannot affect the speed of engine warming, then it is mistaken. It is known that with the additional load of the required temperature, the unit will reach faster than working at idle. Therefore, starting the movement should be as soon as possible. It is enough just to wait for the moment when the turnoves will stop swimming and you can slowly touch, without waiting for the moment when the arrow of the temperature indicator of the coolant moves from the dead point.
Use of comfort of comfort. In cold weather, many motorists think not about how to reduce the consumption of fuel and help the engine to enter the working rhythm, but to ensure their own comfort. Sitting behind the wheel, drivers immediately include the stove, calculating the salon. But since the motor has not yet had time to warm up, the flow of warm air is uneasy, so it is inappropriate to use heating in this case.
Few people think about the fact that during work the stove takes part of the heat from the engine, thereby interfering with it to achieve the operating temperature and take a certain phase of power. As in the first case, "brains" come to the aid to the aggregate, believing that more fuel should be added to the cylinders. Therefore, try to include the salon heating only after the engine temperature reaches 80-90 degrees. Or at least 40ºС.
Driving style. If we can only have an indirect influence on the operation of the motor, then the fuel consumption during the movement depends solely on the driver. It is easy to guess that the supporters of smooth ride are visited by petrol stations less likely those who are accustomed to aggression. Therefore, after its expenses, it will not hurt to learn how to control their emotions and refrain from the unmotivated risk with which it is always conjured by the so-called. Sport style ride.
Reducing fuel consumption contributes to a decrease in the number of stops on the way. Learn to predict road conditions, refrain from routes running through the downloaded roads, as well as secondary roads, where snow removal is rarely peeking. In the process of movement, follow the tachometer indicators and try to keep them in the 2000 rpm area.

Have you noticed that the car consumes a lot of fuel in winter and at another time of the year? This is an important point, negatively affecting the budget. He worries vehicle owners who do not want to throw money into the wind. If you have such an unpleasant situation, familiarize yourself with our publication. In it we will tell why the problem appears and how to reduce fuel consumption using effective methods. After reading the article, you will learn a lot of useful information and will be able to use it to minimize gasoline losses!

Top 5 reasons for fuel consumption

Let's look at the reasons because of which the vehicle consumes a lot of fuel in the winter period. These include:

1. Cooling technical fluids and cold engine - after starting the machine, you need to wait until the working temperature is created for the trip. At this time, the car consumes a lot of fuel.
2. Working stoves in the cabin, heated seats and windshield - to solve such tasks requires a lot of energy. Therefore, the engine consumes an order of magnitude more gasoline and diesel fuel;
3. Reducing tire pressure - with minus temperature indicators, pressure decreases. In this case, rolling resistance increases.
4. Riding on the snow-covered snowdrifts, a car bucking - the snow creates an additional resistance that needs to be overcome. This is spent a lot of energy. It is compensated by increased gasoline consumption.
5. Reducing the speed of movement on a slippery road - this indicator certainly affects the budget.

Fuel economy is a question that interests drivers not only in winter. At another time of the year, the car can also consume a lot of gasoline. What is it connected with? The main objective reasons include later ignition, irregular gaps in the ignition candles, the wear of the cylindrophone group, non-regulated alignment, contaminated fuel injectors, a scored air filter. The generator is also able to take part of the fuel consumption. An increase in the load on the generator may entail a faulty battery. Considering that the defective starter can completely exhaust the AKB resource. Using you can exclude malfunctions of units.

There are also subjective factors due to which the question arises how to reduce fuel consumption. These include the overload of the car above the norm, the installation of spoilers and kites, movement at high speeds with open windows, long-term operation of the climatic and acoustic system.

How to reduce fuel consumption in winter

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

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

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

And one more point: periodically contact a STR in order to verify the technical condition of the vehicle. This refers to the timely replacement of the air filter, cleaning nozzles from contamination, eliminating the malfunction of the gas distribution mechanism. It is also necessary to use oils and liquids, which are recommended by the car manufacturer. When you take into account all the nuances, saving fuel in winter and at other times the year will not be a challenge problem.

Many cars in winter turn into insatiable "monsters". The driver looks at the fuel level indicator, his heart is compressed, and the wallet vibrates. How can you in winter to reduce the fuel consumption?

Increase in the "voraciousness" of the car in winter

Morning, strong frost. The car is cold and completely uncomfortable. The driver includes the ignition, and the engine meets the strong vibration. Sometime comes awareness that he is currently working on wear. It is with this circumstance that the motorist comes an understanding that it is time to install the "Signal" with autorun, or some other device for heating the motor. But if these plans are made, then the consumption of combustible will increase.

But the voyage of the car in the winter to increase and for other reasons.

On a strong frost, the oil becomes more viscous. That is why the engine needs more time to ensure that the assemblies of the unit get better and started moving without further friction.

In order to achieve optimal temperature, the motor needs 15-20 minutes. The fact is that the stronger the frost, the more he will heal longer.

So, in front of the motorist there are two problems: what to do so that the motor does not cool quickly, and how to reduce the viscosity of the engine oil?

Solving the problem of fuel consumption in winter

The easiest and most effective way is the content of the vehicle in good condition, because even the slightest malfunction can cause the machine "Zhor".

We will take at least as an example sensors that sign about the position in which the throttle is located. After all, they understand the "brains" of the car that something goes wrong. And therefore, just in case there is a big, rather than put, fuel supply.

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

With the arrival of cold weather, the oil must be changed. It is not worth saving on it. If you pour the "Painted" oil, then it may be viscous and complicates not only the operation of the engine, but also increase the flow rate of "combustion".

Different additives, which are able to reduce the power of friction in the unit and transmission are not easily. Most of all it is important for a diesel engine - for the quality of diesel fuel in our country is not at the height.

Perfectly showed lubricating additives, well-cope with the "kerosene" trail, because it is very often sinned by little-known gas stations. Use them is preferably after each 3-4 vehicle refueling.

For offseason, good antigels are good, for at that time it is often possible to "run out" on the summer diesel fuel.

So it is better to pour after each refueling. It will not be worse from them, but the chance to run the motor frosty in the morning will increase.

Some motorists make chip tuning. With it, they try to inspire the engine that for full work it is enough for "water with a smell".

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

It is possible to cover the engine in winter by the engine. But it retains heat not more than 5-6 hours. If the machine is not left for a long time, you do not need to warm the motor.
