Why do car owners complain about car fuel consumption?

The resistance of the tires affects the fuel consumption very much! Some tires are wider and have a larger contact area with the ground. The friction is greater, and the resistance is greater. That's why we don't recommend car owners to use big tires!

Therefore, it is necessary to carefully check whether the three-way catalytic converter is useful!

The function of the spark plug is to introduce tens of thousands of volts of high-voltage electricity into the combustion chamber and then ignite the gas mixture. Together with the incineration and sharing system, the engine movement does the work! Whether the car is stable or not is fuel-efficient, all with.

After the three-way catalytic converter has been used for a long time, the role will gradually decline. Of course, this is also related to the current oil, lubricating oil, and road conditions in China. If the temperature of the original catalytic converter is too high, it will simply fail.

After the failure, the electronic fuel injection system can not get the information of the oxygen concentration in the exhaust pipe, and the concentration of the gas mixture in the engine is too high, and it is very easy to add fuel consumption! Is there also a connection between battery and fuel consumption? Of course, the connection between the circuit and the oil circuit is actually very close.

The battery may be used for 2-3 years. The lack of voltage, the lack of motor power, the movement of the engine is naturally affected, the spark plug can not supply a strong spark, and in turn, the incineration energy will become low, which will eventually lead to a surge in fuel consumption!

Do you know how a car can save fuel? - The car is light! (The drag coefficient is not the most fundamental factor, because the drag coefficient plays a role in relation to speed.) But why not produce cheap cars that are equally fuel-efficient to compete with? It's because they make cars for different purposes!

The influence of their own driving habits on fuel consumption is still relatively large, due to the planning of machinery and other factors, the engine needs to run for a period of time to be able to reach the best operation! Often drive at close range, or in other words, a lack of fuel consumption will add 5%-10% of fuel consumption, and there is a risk of puncture! If the tire pressure is too high, it will reduce the service life of the tire!

The tire pressure of the car will generally be written on the manual, the car is not the same as the car, it is better to be cautious! There was once a data calculation that adding 45 kg to the portion, fuel consumption is 2% more! Do the math!

It is no exaggeration that the Kodiak is the most important car of Shanghai Volkswagen and Skoda in the past two or three years. Even, whether Skoda can get out of the dilemma in terms of brand building is all entrusted to Kodiak. BMW has chosen the latest iDrive system on the BMW 5 Series, which is the same as the previous BMW 7 Series, supporting gesture operation and voice control.

It collects hand movements through sensors on the roof of the car in front of the rearview mirror, allowing the driver to look directly ahead, such as "waving" to reject an incoming call, "one-finger click" to access an incoming call, and moving the index finger clockwise or counterclockwise in a circular motion to adjust the volume, etc.

The launch of the 2017 Korega this time, the exterior and interior have not changed much, and the center is originally a price adjustment and a generous model. For example, the comfortable version that looks like the old and new models are all 10,000 yuan, but there is a fashionable version with a lower configuration. ** But it was lowered by 10,000 yuan.

The ** comfort version is much more equipped than the old comfort version.

1. Long-term idling.

Fuel is also consumed when the engine of a car is idling. Generally, it takes more oil to idle a car for more than 1 minute than to start it again, and it is especially expensive to run an air conditioner when idling for a long time and idling. Excessive idle warm-up time not only wastes fuel, increases pollutant emissions, but also increases the risk of engine failure if the car is idling in place for more than 1 minute.

2. Low-gear high-speed driving.

There are some novice friends who drive manual transmission cars, because they do not handle the relationship between gear and speed and do not look at the tachometer, so they often step on the accelerator deeply when they are in low gear, and sometimes the engine speed even exceeds 3500 rpm, which is very fuel-intensive.

3. The clutch is semi-linked.

Some friends like to put their left foot on the clutch pedal for a long time after the car shifts, so that the clutch is in semi-linkage driving, thinking that as long as they don't use force, it will not have any effect. In fact, due to the uneven road surface caused by the bump of the car, the foot also shakes, which is likely to cause the clutch to be in a semi-linkage state.

4. Keep turning the steering wheel while driving.

Some friends always like to keep turning the steering wheel when driving, this kind of rotation is not the need for driving, but a conscious bad action. And the steering wheel is constantly turning, which will undoubtedly increase the rolling resistance of the tires. Curved driving also increases mileage, which naturally increases fuel consumption.

In addition, curved driving can increase tire wear and shorten the life of the tires.

5. Frequent lane changes and overtaking.

In the process of driving, some cars like to drill around in the traffic flow, when changing lanes, they must accelerate and decelerate frequently, and the fuel consumption must be higher than that when driving at a constant speed.

6. Speeding.

The speed limit on highways in China is 110 120 km per hour, and the speed of the car is 80 90 km per hour, which is an economic speed, but in fact, many people will exceed this speed. As a result, the engine provides much more power at high speeds than at medium speeds, and fuel consumption increases dramatically.

7. Drive with windows open at high speed.

Blowing through the windows on the highway will be more fuel-efficient than using an air conditioner, but that's a big mistake. We all know that the power required by the car to overcome the driving resistance is proportional to the cubic of the speed, so opening the windows when the car is driving at high speed will make the air resistance very large, exceeding the power required by the car air conditioner, and the car will increase fuel consumption more than the use of the car air conditioner.

8. Slam on the accelerator to accelerate.

Hard acceleration will increase fuel consumption by more than 30 compared with slow acceleration. Cars that often drive in urban areas have a lot of starts, and a lot of fuel will be saved if the starting acceleration is handled well.

9. Frequent sudden braking.

<> "Don't complain about the high fuel consumption of your car, keep in mind this fuel consumption calculation formula, and you will know the fuel consumption at a glance.

The finished gasoline ** is higher, coupled with the reason for the cold weather in winter, I believe that many car owners complain about the high fuel consumption of the car, and even have a feeling of not being able to drive the car in their hearts. So when judging whether the fuel consumption of a car is high, which calculation method do you prefer? Is it estimated based on the cost of refueling, or is it estimated based on the number of liters of fuel added?

I believe that in the actual process of using the car, there will always be a large number of people who are accustomed to estimating fuel consumption with refueling costs, such as filling the car with 200 yuan of fuel, and the estimated mileage reaches more than 400 kilometers, which means that the vehicle costs 5 cents per kilometer. On the contrary, if the car is filled with 200 yuan of fuel, the result is less than 400 kilometers. Even when it is less than 300 kilometers, car owners may complain about the high fuel consumption of the vehicle, which is simply a "fuel guzzler".

Under normal circumstances, the cost of refueling and the number of kilometers traveled to estimate fuel consumption can be roughly estimated vehicle fuel consumption, but in fact, vehicle fuel consumption is affected by many factors, and this way of estimating fuel consumption is still not very scientific.

So how can we use scientific methods to measure the fuel consumption of vehicles? In fact, there is a formula for estimating vehicle fuel consumption in the automobile industry, as long as the owners keep in mind this fuel consumption calculation formula and use it to measure the fuel consumption of the vehicle, you can basically calculate the approximate fuel consumption of the vehicle.

For example, the fuel consumption of a self-priming engine vehicle with a large amount of luggage is the fuel consumption of the vehicle itself, which means that the standard fuel consumption of the car is about 100 kilometers. The same displacement of automatic transmission models, its fuel consumption of 100 kilometers is. Since the standard fuel consumption per 100 kilometers has been calculated with the fuel consumption calculation formula, which value should be used to compare it with it?

At this point, we need to use the actual fuel consumption of the vehicle, and the specific operation method is also very simple. Here's how:

When the remaining fuel volume of the vehicle fuel tank is about 1 4, drive to the gas station to fill the fuel, and record the current kilometers of the vehicle at the same time; When the vehicle fuel tank is left again 1 4 fuel volume to refuel, again record the number of liters on the vehicle fuel and the number of kilometers traveled on the instrument. For example, the difference between the two kilometers is 500 kilometers, and the second refueling is 35L, at this time, the fuel consumption of the vehicle can be easily calculated: 35L 500 100% = 7L.

Finally, we use the actual fuel consumption of the vehicle to compare with the standard fuel consumption, for example, the use of a manual transmission model, the actual fuel consumption of the vehicle per 100 kilometers 7L is slightly lower than the standard 100 kilometers, which means that the fuel consumption of this car which vertical key performance is acceptable, it is not a vehicle with high fuel consumption, so don't complain about the high fuel consumption of your car.

<> "Behind the Scenes of Higher Fuel Consumption in Cars."

The more you drive, the more fuel you consume? Don't worry, I'll tell you the reasons behind the increase in fuel consumption right away. Check out this fuel-saving recipe so that fuel is no longer "stolen".

Reason 1: Too much carbon deposit.

Vehicles have high fuel consumption, and carbon deposits are often the culprit. Frequent idling, short-distance use, and poor fuel quality can lead to increased carbon deposits. Carbon deposits not only suck away fuel, but also reduce engine efficiency, resulting in poor ignition, increased fuel consumption and even engine scrap.

Resolution. 1. Choose the right fuel and original gasoline detergent.

Car owners should refer to the vehicle's instructions for use to choose the appropriate fuel. The original gasoline detergent can effectively inhibit the formation of sediment, reduce fuel consumption, improve power, optimize exhaust emission indicators, and save energy and protect the environment.

2. Go to the 4S shop on time for fuel system cleaning and maintenance.

The original fuel system cleaning and maintenance kit can remove impurities, carbon deposits and other sediments, improve fuel combustion efficiency, and improve vehicle acceleration performance.

3. Replace the spark plug in time.

The aging of the spark plug can lead to conditions such as the inability of the car to accelerate. It is generally recommended to replace it every 20,000 km. The original spark plug has the advantages of high ignition stability, good electrode wear resistance, self-cleaning function, and long service life.

Reason 2: Three-way catalytic converter failure.

You may not be familiar with the three-way catalytic converter, in fact, it is a device to purify the combustion exhaust gas of the engine, poor fuel quality, poor road conditions, etc., will destroy Sakura Shen and cause problems, reduce the combustion power of the engine, and become the "behind-the-scenes" driving force of the increase in fuel consumption.

Poor quality gasoline contains more impurities and cannot be fully combusted, which will cause the exhaust to be unobstructed and make the three-way catalytic converter fail.

2. Clean the engine carbon deposits regularly.

If you often run at high speeds, it is recommended to clean it every 2-30,000 kilometers; If you often run short distances, or if the road conditions are bad and you are often stuck in traffic, it is recommended to wash every 10,000 kilometers.

Reason 3: The tire pressure is too low.

This knowledge point can be described as a "cliché", too low tire pressure will increase the friction between the tire and the ground, and increase fuel consumption. In addition, the "face" of the tire is also important, and excessive wear of the tread will also lead to an increase in fuel consumption.

Tips: If the tire is eccentric wear, you should go to the 4S shop in time for four-wheel alignment; If the tire is worn in the middle, the tire pressure is too high, and it should be adjusted appropriately.

Reason 4: Poor car habits.

If you want to reduce fuel consumption, car owners can have a long snack, and the following three points must not be missing:

1. Maintain on time.

The car needs "health" like us, and regular maintenance at the Xianjing 4S store will help maintain the car's full score.

2. Smooth driving.

Slamming on the accelerator and braking hard can be very fuel-guzzling and should be avoided as much as possible to maintain a smooth drive.

3. Avoid idling.

Long-term idling will also make fuel consumption rub off**, so you should try to choose a road with good road conditions.

When every car owner buys a car, it is estimated that they will first ask what the fuel consumption of their car will be, because it involves their daily car maintenance costs and maintenance costs. If you don't figure this out, you're likely to fall into infinite pain. For example, the fuel consumption of a new car is getting higher and higher, and then you don't know what the problem is, so let's take a look at it together.

1. The hot car time is too long.

Everyone knows that the car idling consumes more fuel, and even idling for one minute consumes more fuel than restarting, so you should try to avoid idling for too long, and if you stop for a long time, you can turn off the engine.

When starting a cold car, you should know that you don't need to artificially extend the heating time of the engine, because doing so will only be counterproductive.

2. Tires. First of all, check whether the tire pressure is normal, because if the tire pressure is too low, it will increase the rolling resistance of the tire, which will increase the ground contact of the tire and increase the friction, which will lead to an increase in fuel consumption.

The tire pressure should not be too high or too low, generally there will be a recommended tire pressure value on the fuel tank cap, and it will be enough to inflate it according to the above standard.

3. Replace the battery regularly.

Friends who have a dash cam or like to charge in the car know that there is a battery in the car that is responsible for the circuit in the car. The battery also has a service life, generally 2-3 years will produce a power deficit problem, so that the insufficient voltage in the car leads to the motor weakness, which will further affect the increase in fuel consumption.

4. Check and replace the spark plug and fuel injector.

Spark plugs and fuel injectors are an important part of a car's fuel incineration, and these two parts are rarely damaged, but that doesn't mean there won't be problems over time.

The spark plug will weaken the incineration energy due to the normal wear and tear during operation, and the fuel injector will not work normally due to oil problems or serious carbon deposits in the cylinder, thus showing the symptoms of slowing down the speed of the vehicle and increasing fuel consumption.

5. Excessive carbon deposits.

With the increase in the number of people with cars, it has also led to traffic jams during commuting hours in the city, and more and more carbon will naturally accumulate over time.

Secondly, the quality of oil products is not the same in various places, and even some car owners are greedy for cheap and add some poor-quality gasoline, which will also increase the carbon deposit of the engine.

6. Air filter.

The air cleaner is like a mask for the engine, located at the front of the engine's air intake. Its function is to filter the air inhaled by the engine and ensure the cleanliness of the gas mixture required for engine combustion.

If the air cleaner is over-polluted, it will increase the intake resistance of the engine, resulting in a decrease in engine power, an increase in fuel consumption, and a high risk of carbon deposits.

In fact, we all take care of the new car when we first bring it home, but after the freshness has passed, we start to pay no attention to the details. It is the key to keep cherishing all the time, and some old drivers still maintain the car very well after a few years.
