Consultation on the problem of increased fuel consumption of automobiles.

Seeing the sudden surge in fuel consumption, everyone's hearts must be very resistant. The following is a brief science popularization of the three aspects that are easy to increase the fuel consumption of the car, and then go to the repair shop after checking these 3 parts to avoid additional costs.

1: Insufficient tire pressure, modified and widened tread.

Problems such as tire modification or insufficient air pressure can cause fuel consumption to increase. Vehicles leave the factory after comprehensive consideration to choose the right size of tires, but some owners will modify larger and wider tires for some reason. When the tire is modified to become wider, the area it is in contact with the ground will increase, the friction will increase, and the natural fuel consumption will increase.

2: Add low-quality gasoline.

The quality of gasoline is directly related to the size of fuel consumption, too many impurities in inferior gasoline will block the oil circuit, resulting in poor atomization of the fuel injector, the mixture is too thick, and the fuel is discharged without full combustion, resulting in a rapid rise in fuel consumption. Moreover, low-quality gasoline does not burn sufficiently, so it cannot provide enough power.

3: The oil and three filters have not been replaced for a long time.

The three filters of automobiles refer to the oil filter, the air filter, and the gasoline filter. They are just like the masks we use, which are used to filter and block harmful substances from entering the engine, and if they are not replaced for a long time, the fuel supply and air intake of the engine will be blocked, resulting in the increase of the amount of fuel injected by the computer to the engine.

After the thief leveled, he sent people back to the north (Sikong Shu).

The fuel consumption of the car has increased, and this problem can be solved from the following aspects.

If the air pressure in the tires is not enough, the fuel consumption will increase. If the air pressure is normal, you should check the wear of the tires, severe tires will cause slippage and increase fuel consumption. Usually, the normal tire pressure of the car will be in the car product manual or on the nameplate of the car B-pillar, please choose a reasonable tire pressure according to the above tips.

If the engine deposits too much carbon in a short period of time, then it will lead to an increase in fuel consumption, most likely due to the use of substandard oil. The solution is to add a certain amount of engine cleaner when refueling, if it still can't solve this problem well, then it may be too much carbon deposit, and you need to go to the 4S store for special treatment.

Now there are many ways to deal with carbon deposits, one is to play "hanging bottles", and the other is to dismantle the engine and clean the entire engine.

If the oxygen sensor on the front is damaged, it will lead to increased fuel consumption, and the main function of the oxygen sensor is to detect the oxygen level in the air and adjust it. Once a failure occurs, it causes an inaccurate signal, giving the wrong signal, which incorrectly directs the ECU fuel injection, which increases the fuel consumption of the car.

The leakage of the high-pressure oil pump will cause the fuel to leak into the engine and mix with the engine oil, causing the oil to increase and the fuel consumption to increase. If the fuel consumption of your car is relatively high, you can open the engine cover and smell it, if there is a strong smell of gasoline, it means that your high-pressure oil pump has been broken, and this damage will inevitably lead to an increase in fuel consumption.

This sensor can not only detect the water temperature, but also the temperature of the engine, at low temperatures, the car will increase the fuel, so that the engine heats up faster, if the water temperature sensor is not accurate, it will continue to send out wrong signals, resulting in the engine continues to increase the amount of fuel injected, resulting in high fuel consumption failure.

Cleaning up carbon deposits, checking tire pressure, checking the engine, changing the oil, checking whether the oxygen sensor is damaged, and checking or replacing all of these can solve the problem.

The fuel consumption of the car has increased, and you should go to the maintenance shop to change the oil of the car so that the fuel consumption is a little less.

Be sure to change your usual driving habits, don't slam on the brakes, don't slam on the accelerator, do maintenance frequently, be sure to pay attention to the quality of the oil, and clean up the carbon deposits every once in a while.

<> "Experienced old drivers usually drive for a long time and probably understand how much fuel consumption they need to drive a distance, but gradually he found that the fuel consumption of the same distance began to increase! Here's how to find the problem of increased fuel consumption.

1.While driving, I found that the coasting distance of my car is now significantly reduced. At this time, car owners should check whether the air pressure of the tires meets the air pressure standard. If the tires are underinflated, fuel consumption will also increase.

2. Check the degree of wear and tear of the tires. If the tires are severely worn, they will often slip and increase fuel consumption.

3. Abnormal noise is found in the wheel during driving or starting. Netizens should check whether the bearing and brake system are faulty in time. If the wheels do not rotate properly, it will affect the speed of the vehicle and increase fuel consumption.

4. Clutch slippage will cause the engine to lose its revolutions. 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.

5. When the vehicle has been driving two or three hundred thousand kilometers late, there is usually a phenomenon of insufficient cylinder pressure. At this time, fuel consumption will increase significantly.

6. When the exhaust pipe emits black smoke and the fuel consumption increases, the carburetor needs to be checked.

7. If the spark plug is used for too long, the fuel consumption will also increase. Because the spark plug is damaged and the ignition energy decreases, the car slows down the speed, resulting in a significant increase in gasoline consumption.

8. When the temperature control switch and thermostat of the car are damaged, the fuel consumption will increase. Because the damage of the temperature control switch and thermostat will reduce the water temperature, the carburetor cannot work normally, resulting in poor atomization of gasoline and a significant increase in fuel consumption.

It is recommended to take the car to the repair shop regularly for maintenance, which is the most fundamental way to ensure that the car can extend its service life.

1.Insufficient 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.

Therefore, the quality of gasoline cannot be ignored, and it is essential to clean up carbon deposits every six months.

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. Therefore, it is necessary to check the condition of the oxygen sensor regularly, and it usually needs to be replaced at 8-110,000 kilometers.

In the event that the fuel consumption is higher than usual, you can go and check the spark plugs. The spark plug is a passing device and the most important part of starting the car, and the vehicle will age all the time, making ignition more difficult.

After buying a car, I believe that many friends have encountered the phenomenon of a sudden increase in fuel consumption of the car, so what is the reason for the high fuel consumption of the car? Seven reasons why the fuel consumption of the car is too high, you will know after reading it!

Stepping on the accelerator and slamming on the brakes are important factors that cause the increase in fuel consumption, and the driver should develop good driving habits when driving, which is not only a way to save fuel, but also helps the maintenance of the engine, prolongs the service life of the engine, and makes the car better serve us.

Carbon build-up in the engine.

After driving for a long time, the fuel consumption will slowly increase, in fact, the problem may lie in the carbon deposition machine, because the carbon deposition is scorched when the car is cold, but as the engine temperature rises, it will gradually soften and absorb the fuel injected by the fuel injector, resulting in higher fuel consumption. To clean the carbon deposits inside the engine, you can use cleaning liquid or walnut sand tools.

Do not turn off the ignition or light it frequently when idling for a long time.

When the car is idling for a long time, the fuel consumption is also quite large. Experiments have shown that three minutes of idling is equivalent to one kilometer of fuel. If the idle time reaches two hours, it is almost 2 to 3 litres of oil.

Frequent engine starts is a manifestation of "car abuse". Because the amount of fuel injected by the computer is more when the engine is started, starting the engine frequently over a period of time will definitely increase the fuel consumption of the vehicle.

The hot time is too long or the driving distance is too short in the morning.

It's a good habit to warm up the car for a short time in the morning, but waiting for the speed of the car to drop to normal or the water temperature to rise to normal is tantamount to having trouble with your wallet.

The owner can start the vehicle for about half a minute to drive, and then drive normally after driving a distance in 1st gear.

The oil was mislabeled.

As the blood of automobile engine, engine oil plays the role of coarse lubrication, friction reduction, cooling and cooling. However, many car owners only care about the brand of engine oil when changing the oil, and do not pay attention to the viscosity of the oil. It is important to know that the viscosity of the engine oil used by the car in different seasons is also different, even if the so-called all-season general engine oil is used, there will be a certain gap in fuel consumption.

If you add a machine that is not suitable for your own car to return to the town, the viscosity is high, the internal resistance will inevitably rise, the resistance is high, the power will inevitably become weaker, and the fuel consumption will also rise in a straight line.

Abnormal tire pressure or changing large tires.

Every summer, many cars have flat tires due to high temperatures. In order to prevent tire puncture, many car owners will specially reduce the tire pressure. However, if the tire pressure is too low, the friction between the tire and the ground will increase, and the resistance will increase, resulting in an increase in the fuel consumption of the car.

And too low tire pressure will also increase the risk of puncture, so you must not specifically tire pressure.

Of course, if the owner inflats the tire too much and replaces the tire with too narrow tire width, it will increase the possibility of puncture, tire eccentricity and reduced driving comfort.

The vehicle increases the load for no reason.

The fuel consumption of the vehicle will rise accordingly when each increase in its own weight, so it is recommended that the owner decorate the car within a reasonable range, and it is time to reduce the burden on the car at the appropriate time.

Solutions to increase fuel consumption: 1. Increase 4 wheel air pressure to reduce friction, it is recommended that the tire pressure in winter is higher than in summer, but not exceeded; 2. Clean up unnecessary debris on the car and reduce the weight of the car; 3. Improve the average speed, the economic car disturbance and speed is 60 to 90 kilometers per hour, you can use the following driving skills, such as early gear shifting, coasting and parking, smooth driving and slow staring, with the economic speed, can greatly reduce fuel consumption; 4. Appropriate use of auxiliary electrical appliances in the car, the use of some electrical equipment will significantly increase fuel consumption, such as the rear windshield heater should be turned off in time when there is no fog or ice; 5. Maintain the engine regularly, and maintain it in strict accordance with the maintenance cycle, especially the oil, coolant, etc., so that the engine has a good working environment, and at the same time, it is also necessary to regularly clean up the carbon deposits and replace the air filter, so that the engine can breathe more smoothly.
