The reasons for the high fuel consumption. Rate of fuel consumption

Every car owner is able to save fuel. The main thing is to follow certain rules. First of all, it is necessary to identify the main causes of high fuel consumption. There are many factors that can affect this indicator. After identifying the problem, you can find its solution.

The first rule of economy

In some cases, a very high fuel consumption is due to a peculiar driving style. It is not deadly, and if desired, you can change it. In this case, it is necessary to observe a simple rule: the more quietly you go, the further you will be. Approximately 10% increase in fuel consumption during rapid acceleration and sudden braking. A similar phenomenon can often be observed at traffic lights. However, a quick start always raises fuel consumption. After all, in this mode, more fuel is supplied to the cylinders.

To significantly reduce costs, you need to learn how to ride smoothly. In such situations, it is worthwhile to avoid sharp rearrangement to other bands. Also it is necessary to avoid unnecessary movements and accelerations. Before the red traffic light signal, you can remove your foot from the gas in advance. As a result, the car will run downhill. As a result of such actions, intensive braking is not required. In addition, the situation on the road should be taken into account. On long descents it is necessary to use braking by the engine, but in a long stopper it can be completely drowned out.

Economical mode

If you have a large fuel consumption, then you should take advantage of the economical mode. This function is provided in many vehicles with automatic transmission. If you do not have a similar mode, you can move the selector to the position that corresponds to the winter program. Of course, there are some peculiarities here. In this situation, automation will include higher programs much earlier. In addition, it is worth remembering that when the economy mode is switched on, the engine power is reduced. This fact is not satisfied with every driver.

Tire pressure

A large fuel consumption can result from improper tire pressure. Therefore, it is necessary to regularly check this indicator. Insufficient pressure in the wheels of the vehicle can increase rolling resistance. As a result, this negatively affects the stability and controllability, and also harms the tires. Reduce fuel consumption by slightly pumping the tires. A little cunning is the guarantee of saving.

In addition, lower fuel consumption allows modern tires that have a sufficiently low rolling resistance. They are also called energy-saving.

Optional Accessories

Today it is difficult to imagine a car without additional devices that not only improve the quality and comfort of driving, but also consume electricity. As a result, there is a large consumption of fuel. Among these accessories is to allocate air conditioning. Its use will cost the car owner in 0,8 liters of fuel approximately on 100 kilometers.

In addition, the new traffic rules provide for the movement of vehicles in the daytime with the lights on. And this is another reason for the high fuel consumption. However, there is always a way out. You can use special LED running lights. They consume significantly less power. In addition, their service life is much greater than that of conventional light bulbs.

Engine warm-up

Why does a large fuel consumption occur in the cold season? A similar phenomenon can be with the constant warming up of the engine after a cold start to the operating temperature. If possible, you should move as soon as possible. After all, under loads, the engine warms up much faster than when idling. If you need to save on fuel, it is worth shortening the engine warm-up to a perfectly acceptable time, rather than warming up the mechanism for half an hour.

Aerodynamics

All that somehow prevents aerodynamics, can increase fuel consumption. Among such products it is worthwhile to allocate a wide-profile rubber, the exploitation of which is not provided for by vehicle manufacturers. Also, do not install any accessories on the hood and decorative spoilers. It is worth noting that a large fuel consumption can be caused even by the luggage compartment on the roof of the vehicle. If you do not use such an accessory, then it is better to remove it.

Vehicle class and engine volume

These are several factors that affect fuel consumption. In addition, this indicator is also affected by the quality of fuel, and automatic transmission. Do not expect a small fuel consumption from a vehicle that has impressive dimensions, for example from a jeep. Some climatic factors should also be taken into account. For example, in winter, the engine must be warmed up and the stove used. Because of this, a lot of fuel is consumed. "VAZ" often suffers because of severe frosts. Also do not forget that the audio system, lights and air conditioning are those accessories, the work of which reduces to some extent the power of the motor. As a result, the fuel consumption of the vehicle is increased.

Freight forwarding

When transporting a large cargo, there is also a large fuel consumption. For example, every extra 100 kilograms increases the consumption by about 10%, the loaded trunk, which is located on the roof - by 40%, empty - only by 5%, trailer - by 60%. Therefore, if you plan to transport large loads, please note that high fuel costs can not be avoided.

The reasons for the high fuel consumption. How to solve a problem?

There are reasons for the high fuel consumption, which can be eliminated on their own. The main thing is to correctly identify the source of the problem. Here are the main factors:

1. Headlight. As already mentioned, the use of such devices increases fuel consumption. For example, when using dipped beam, fuel costs are increased by 5%, and when using a dipped beam, by 10%. In the daytime, it is worthwhile to include running LED lights.
2. The temperature of the coolant is much lower than the design values. In other words, the vehicle motor does not warm up to the required level. This problem usually occurs in the winter. Therefore, it is necessary to use special materials that can keep the heat under the hood, for example, a carpet snooze.
3. Do not forget that some problems arise due to the fact that the gearbox or carburetor is not working properly. The big expense of fuel is a basic problem of vehicles equipped with automatic transmission. More modern models are equipped with gearboxes that have an economical mode.
4. The quality of fuel. The reasons for the high fuel consumption may be in poor fuel. If the manufacturer recommends refueling the vehicle with AI-95 fuel, then it should be done. If you use the 92nd gasoline, the fuel costs will increase significantly. If you fill the car with high-octane fuel, the consumption will be significantly reduced. However, the cost of gasoline will be higher.
5. Bad roll on. This indicator can also be checked independently. To do this, you need to accelerate, and then transfer the vehicle to neutral transmission. To brake it is not necessary. Nakat is the way that will be done by the vehicle from the moment when the gas pedal was released, and until its complete stop. If the car parts are in poor condition, fuel consumption may be increased.

Rate of fuel consumption

The Ministry of Transport of the Russian Federation published in 2008 recommendations on fuel consumption standards. It is worth noting that these figures depend on the brand and classification of the vehicle. However, if you want, you can calculate everything. So, what will be the rate of fuel consumption? The Ministry of Transport of the Russian Federation has resulted the formula, thanks to which it is possible to determine this indicator.

For passenger cars, the fuel consumption rate can be calculated as follows:

Q n = 0.01 x Hs x S x (1 + 0.01 x D), where Q n is the normative fuel consumption.

Hs is the basic rate of fuel consumption for a certain mileage of the vehicle.

D is the correction factor to the norm in percent.

S - mileage of the vehicle in kilometers.

Finally

If your car has a high fuel consumption, what should you do? The problems of such a plan are not only in the malfunction of the vehicle. Perhaps the problem arises from the use of additional accessories and devices, and also because of the style of driving. Compliance with simple rules will significantly save on fuel. In addition, do not forget about the norms of fuel consumption. If desired, this figure can be calculated independently.
