The fuel consumption of the car has somehow increased, what should I do?

If you notice a significant increase in fuel consumption in your car, there may be a problem with your car, and there are six ways to find the cause and remedy it. 1。Check the degree of wear and tear of the tires.

If the tires are severely worn, there will be frequent slippage, which will increase fuel consumption. Pro tip: Replace your tires with new ones.

2。If you notice that your car is coasting significantly less distance while driving, you should check the air pressure on your tires. If the tires are underinflated, fuel consumption will also increase.

3。If you find that the wheels have an abnormal sound while driving, you should check the bearing and brake system. If the wheels do not rotate properly, it will affect the speed of the vehicle and increase fuel consumption.

Expert advice: Frequent maintenance of bearings and brake systems. 4。

Clutch slippage can reduce engine output efficiency. When you accelerate sharply and notice that the engine tachometer increases quickly but the speed increases slowly, you can tell that the clutch has slipped. Expert advice:

Replace the clutch plate and clutch pressure plate. 5。If your car has driven two or three hundred thousand kilometers, there may be a lack of cylinder pressure, and then fuel consumption will increase significantly.

Expert advice: overhaul of the engine. 6。

When there is black smoke coming out of the exhaust pipe, the EFI system needs to be checked.

It is recommended to use Tianjin Shunneng ceramic alloy lubricating oil to effectively remove carbon sludge from the engine, improve engine sealing, and effectively solve the problem of increased fuel consumption caused by carbon deposit and air leakage.

It is recommended to check from several aspects such as tires, brake system, clutch, etc., and can also replace Sunny ceramic alloy lubricating oil, which has an extraordinary energy-saving effect, which can significantly improve power, enhance horsepower, and save an average of 10% of fuel.

If it is an old car, it is best to go to the auto repair shop for maintenance, the reason is more complicated, and it is not clear in one sentence or two.

If you open less, you will save fuel, brother, there must be a problem with always opening.

The fuel consumption of automobiles has always been a concern for us. In fact, the sudden increase in fuel consumption is mainly due to traffic jams, aging spark plugs, increased carbon deposits, and long-term maintenance of the car. Below, let's explain these four reasons one by one.

1. Traffic jams. When we commute to work, we often encounter traffic jams. At this time, extremely low-speed driving, which can also be said to be idling, will lead to a significant increase in the fuel consumption of the car.

2. Spark plug aging. Spark plugs are actually one of the spare parts that need to be replaced frequently. Once the spark plug is not replaced in time, the ignition performance will be reduced, which will also lead to insufficient combustion of the fuel.

Eventually, this will lead to an increase in gasoline consumption, and the spark plugs should be replaced regularly.

3. Increase in carbon deposits. When you should use high-gauge gasoline, such as 95 gasoline, when you are actually using 92 gasoline, it will increase the carbon deposits inside the engine. And when carbon deposits increase, it will actually lead to an increase in fuel consumption.

Of course, the most serious is the knocking, and the increase in fuel consumption is a minor problem.

4. The car has not been maintained for a long time. When actually driving, it is best to have your vehicle inspected and maintained regularly. For example, cylinder wear and tire wear are actually the reasons for the increase in vehicle fuel consumption.

At this time, in fact, fuel consumption is no longer the key issue, but to extend the life of the vehicle and ensure their driving safety.

: There are many reasons for the increase in fuel consumption. But the most common and easily overlooked by car owners is the check of tire pressure. Insufficient tire pressure will not only lead to increased driving resistance, resulting in higher fuel consumption, but also affect the service life of the tire.

Maintenance method: When driving, pay more attention to whether each tire is inflated, and check the tire pressure regularly. Of course, don't forget to check the spare tire, so as not to find that the spare tire has run flat when you urgently need to replace the tire.

Tire pressure can be higher than usual when temperatures are high, so it's more accurate to measure tire pressure in the cold or shade. Often, tires should be swapped every 10,000 kilometers to avoid too much difference in front and rear wear. If you need to replace severely worn tires, it is best to replace two or four tires together, and tires with the same texture can be replaced front and back.

In addition, tires with a polyline pattern help save fuel.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Fuel consumption has increased, mainly due to the fact that the engine produces more carbon deposits, which is caused by poor combustion, and it is necessary to clean the throttle and fuel injector, replace the spark plug, and also need to check the engine, there is more carbon in the cylinder, which also needs to be cleaned, and the three-way catalytic converter needs to be checked to see if there is any blockage, and the data flow of the air intake sensor and oxygen sensor is detected by the computer to see if there is a problem. In addition, in the case of low temperature in winter, the fuel consumption of the vehicle itself will increase, no matter what model it is, the fuel consumption will increase in this winter.

The reasons for the sudden increase in fuel consumption of automobiles are: poor ignition of the fire nozzle, serious carbon volume of the cylinder, lack of air blocking in the style, and too much viscosity resistance of the oil.

1. The hot car time is too long or the driving distance is too short: when the engine water temperature is too low, the computer will control the fuel injector to spray more fuel, so if your commute is very close and the water temperature is not easy to rise to normal in the cold weather of winter, then it may become a typical example of high fuel consumption.

2. Abnormal tire pressure: When the tire is underinflated, it will affect the fuel consumption. Of course, if the tire is filled with too much air pressure and the tire width is too narrow, it will increase the possibility of puncture, tire eccentricity and reduced driving comfort.

3. Frequent lane changes due to congestion on driving roads: Choose the least congested route between the departure point and the destination. Reducing the number of starts and stops and driving at an economical speed saves you fuel.

There is also a lane change, which not only accelerates and decelerates, but also does not travel as short as a straight-line distance.

4. Lack of regular cleaning: It is recommended to clean the appearance of the vehicle frequently, and regular waxing of the vehicle is also a good way to save fuel. The biggest drag on the vehicle comes from the air, and too much dirt on the vehicle and snow on the body in winter are also a burden on the vehicle.

5. Do not turn off the engine or frequent ignition when idling: When you encounter a long time waiting without moving the vehicle, it is recommended to turn off the engine, which is the best way to save fuel. And frequent engine starting, it is a manifestation of "car abuse";

6. Violent refueling and frequent braking: starting, refueling, and shifting according to the normal rhythm, you can save a lot of fuel after accumulation. It is best not to overtake frequently, and driving at a constant speed can reduce fuel consumption.

Minimizing unnecessary braking action will also give you the pleasure of saving fuel.

7. Increase the load for no reason: blindly adding a large surround, rear wing, winch, and luggage rack to the car will also increase the fuel consumption of the vehicle.

8. The oil is not filled according to the specified label: the viscosity of the oil is the main indicator of the oil, and the larger the value after the w", the better the protection performance of the oil at high temperatures. Excessive selection of higher viscosity oils increases the drag of engine components, which consumes both power and fuel consumption.

9. Low-gear high-speed or high-gear low-speed driving: the higher the engine speed, the higher the fuel consumption, the higher the fuel consumption. If the car is already shaking and is likely to stall at any moment, increasing the throttle means that the fuel injection volume is up, and the best way to solve it is to downshift.

10. Turn on the air conditioner when the windows are fully open and the traffic jam is closed: the fuel consumption of the engine load will also increase when the air conditioning is turned on in summer. It is advisable to open the window to cool down at low speeds, while it is more cost-effective to turn on the air conditioner at medium and high speeds.

If there is a traffic jam and the temperature is acceptable, it is better to turn off the air conditioner if you want to save fuel.

If the fuel consumption of the car suddenly increases, do not rush to the repair shop to clean the oil circuit and carbon deposits, because they have a fixed cleaning cycle, and they are not likely to cause high fuel consumption. It is recommended that you focus on the three parts of the front oxygen sensor, air flow meter, and carbon canister solenoid valve.

There are several reasons why vehicle fuel consumption becomes high:1Insufficient tire pressure and tire wear.

If the tire pressure is insufficient or too low, the friction between the tire and the ground will increase, and the drag will increase, and the fuel consumption will increase. If the tires are severely worn, they will often slip and fuel consumption will also increase. 2.

Pay attention to the quality of refueling, and clean up carbon deposits regularly. Poor quality gasoline will increase carbon deposits, and excessive carbon deposits will make the intake pipe wall rough, affecting the air intake effect and the quality of the mixture, and causing fuel consumption to rise sharply. 3.

Check your oxygen sensor regularly. This is a ceramic element located on the exhaust pipe of the engine that detects and controls the ratio of oxygen to fuel. After a long period of use, the computer of the electronic fuel injection system cannot obtain information about the oxygen concentration in the exhaust pipe, and the mixture concentration in the engine tends to be high, and the fuel consumption will also increase.

4.Driving habits. Everyone's habits of driving a vehicle are different, and poor driving habits can also lead to high fuel consumption.

Such as "hard acceleration, floor oil at start, etc.", so good driving habits are important factors that do not make fuel consumption high. 5.Driving road conditions.

If the driving road is very congested, it will also lead to high fuel consumption, because the engine work is relatively large when the vehicle is from stationary to moving, and because it has to overcome the friction on the ground, the amount of fuel injection will also increase, so the fuel consumption will be high. 6.Replace the spark plugs regularly.

The function of the spark plug is to generate an electric spark with high voltage electricity to ignite the mixture. If damaged, the ignition energy will decrease, and the mixture will burn unevenly, resulting in a slowdown in the speed of the car and an increase in fuel consumption.

There are three main aspects of the sudden increase in fuel consumption of the car:

After a period of normal use, the tire pressure will be insufficient, and the low tire pressure will naturally increase fuel consumption. At this time, you should check whether the tire pressure meets the air pressure standard. If it is not a problem of tire pressure, it is necessary to check the degree of wear of the tire, if the tire is seriously worn, there will be slippage and other phenomena, which will also cause an increase in fuel consumption.

2.Changes in four-wheel alignment data can also lead to an increase in fuel consumption.

Generally, after replacing the tires, the four-wheel alignment will be carried out, and there will be no deviation under normal circumstances, if there is a change in the data, it is mostly caused by the failure of the chassis parts, such as the steering rod, swing arm, front shock absorber, balance bar rubber sleeve, etc. If the toe-in and inclination data of the wheels deviate too much, the friction between the tire and the ground will increase, resulting in an increase in fuel consumption.

3.Poor driving habits lead to high fuel consumption.

Sudden braking, frequent overspeeding or turtle speed, and shifting too high or too low speed are the main causes of high fuel consumption. In the process of driving, the gentle and smooth driving style is the most fuel-efficient; Try to avoid slamming on the accelerator when starting, and drive smoothly and at a constant speed is the most fuel-efficient; Seeing the road ahead in congested sections and avoiding sudden braking not only saves fuel, but also reduces vehicle wear.

There are two reasons for high fuel consumption. One is that the engine is unstable and lacks cylinders. The second is that there is less fuel at the gas station, and I have tried. The same plus 100 yuan, the same Yancheng Expressway, 220 kilometers at a time, 250 kilometers at a time.

How many is your average fuel consumption, has it always been? How much to run in**? Often running in the city and often running on the road is 1-2 liters higher. And how many miles have you run, if you haven't changed the spark plug for 3-50,000 yuan, check the spark plug.

Hehe, your car is Sail? In terms of increased fuel consumption, the most common problems in terms of Sail engines: 1

The carbon deposit in the air intake and fuel system can be checked, and some cleaning or burning cleaning agent can be added appropriately; 2.Check the ignition system, the sub-cylinder line and the spark plug to see if it needs to be replaced. 3.

If it's an automatic transmission, isn't it time to clean and change the oil? Start simple, from the inside out.

11 is not much, my 12, in addition, it is a 4S store, not a CS store, and there are more CS Internet cafes.

My broken car is almost fine, and I'm ready to buy a good car and I'm going to come to Gamo Saint Hehe!

1. If the oil circuit is dirty, the oil is good for routine maintenance;

2. The weather is cooler, the preheating is sufficient, and the short-distance driving in cold weather will also be the same;

4. Caused by wear and tear of old car accessories;

5. Engine aging will also be the cause of this.

Constant-speed fuel economy: Constant-speed fuel economy refers to the fuel economy index of the car when driving at constant speed on a good road surface. Because constant speed driving is a basic working condition for cars to run on the road, and this fuel consumption is easy to measure, it is widely used.

For example, France and Germany regard the constant velocity fuel consumption of 90km h and 120km h as the main evaluation index of fuel economy.

This indicator is also used in my country. The fuel consumption of 100 kilometers indicated on the manual of domestic cars is generally the fuel consumption at the same velocity. However, due to the fact that the car often accelerates, decelerates, brakes and idles in the actual driving and other working conditions, the constant speed fuel consumption is often low, and the actual fuel consumption is quite different.

The difference is even greater for cars that often travel short distances in the city.
