How to repair the increase in fuel consumption of the vehicle? How to repair a car with high fuel co

First of all, you should go to the maintenance center to monitor the engine electronic data and detect the vehicle exhaust, and make a diagnosis according to the following ideas:

1) Tire charging pressure: If the tire loses air, it will lead to an increase in driving resistance, resulting in an increase in fuel consumption; On the contrary, if the tire pressure is appropriately increased within the specified value, it will help to reduce fuel consumption.

2) Tire pattern: The fuel consumption rate of different types of tires with different patterns is different, and choosing polyline tires can help save fuel.

3) Four-wheel alignment: always keep the wheel alignment value correct, which can ensure a low fuel consumption rate.

4) Driving environment: the lower the time occupancy rate of the idle speed and low gear of the vehicle for the whole driving cycle, the more conducive to reducing fuel consumption. Therefore, in urban congestion, fuel consumption remains high.

5) Road conditions: the greater the road resistance, the more uphill and downhill road conditions, and the higher the fuel consumption rate. So try to choose paved, flat roads to drive.

6) Vehicle load: minimize unnecessary items in the car and luggage, which helps to reduce fuel consumption.

7) Smooth acceleration: The instantaneous fuel consumption rate during rapid acceleration is half higher than that during smooth acceleration, so we should try to avoid rapid acceleration and emergency braking.

8) Moderate speed: clear economic speed, too high or too low speed will make the fuel economy of the vehicle worse.

9) Engine technical condition: If the technical condition of the engine is poor, it will lead to a decrease in engine power and cause a lot of fuel waste.

10) Automatic transmission: ensure that the automatic transmission shifts normally.

11) Transmission system: regularly check whether the rotation resistance of transmission shafts, differentials, half shafts, hoop bearings and other components is normal.

12) Braking system: check to ensure that there is no lag in the braking system.

13) Viscosity of gear oil: In the environment with relatively low temperature, replace the gear oil in the manual transmission and differential with a lower viscosity mark, which helps to save fuel.

14) Wind resistance coefficient: if the appearance of the vehicle is damaged, open the window, or due to improper modification and other factors.

Test tire pressure, keep your wheel alignment accurate, drive as flat on the continent as possible, etc.1

Maintenance methods with high fuel consumption: 1. Clean up the engine, too much carbon deposition in the engine is a very important reason, mainly because of the use of unsuitable oil. It is recommended to add a certain amount of detergent when refueling;

2. And after you finish cleaning, it is best to drive at high speed, which is conducive to increasing the exhaust volume and allowing the stronger airflow to bring out the larger carbon particles;

3. Check the oxygen sensor, as the internal control unit of the car, the oxygen sensor is mainly to monitor the engine oil and gas ratio, once it is damaged, it will cause the engine oil and gas ratio to be out of balance, and the fuel consumption will definitely increase suddenly;

4. After the oxygen sensor is damaged, the exhaust pipe will discharge the darker exhaust gas during the driving process, and the oxygen sensor should be replaced when the new potatoes are attacked;

5. Replace the three filters regularly, the oil filter, air filter and gasoline filter must be replaced regularly during the use of the vehicle, if they are not replaced for a long time, they will become dirty, affect the use, and the person will transmit wrong information to the engine control unit, resulting in insufficient fuel combustion and increased engine carbon deposit.

Millions of car purchase subsidies.

1.It is normal for fuel consumption to fluctuate depending on temperature. Generally, the fuel consumption will increase when the temperature is low in winter, which is almost equal to the fuel consumption when the air is adjusted in summer.

This is because the temperature is low and the heat emitted by the engine increases. In order for the engine to maintain a constant temperature for it to function properly, more gasoline needs to be burned to generate heat for more heat dissipation. This part of the gasoline is not used to do work, and the heat is wasted, so the fuel consumption will increase, which is inevitable.

2.If the vehicle is not serviced for a long time, the oil and air filter elements will become dirty, which will also lead to increased fuel consumption. Dirty oil can lead to poor lubrication, resulting in increased resistance to all moving parts of the engine.

3.The spark plug should be replaced. Spark plugs are easy to ignore, and some people have not changed them for more than 100,000 kilometers.

When the life of the spark plug is up, although it can still be used, it will delay the ignition due to the lack of ignition energy, and miss the best ignition time. For example, when the piston is close to the top dead center, the gasoline should have been ignited. Due to the lack of ignition energy, the ignition is delayed, and the piston starts to move downward before ignition, which will lead to the loss of some power, and a large amount of energy is not used to do work.

4.Insufficient air pressure. Insufficient air pressure will lead to an increase in the contact area between the tire and the ground, and an increase in friction, that is, an increase in driving resistance and an increase in fuel consumption.

Insufficient air pressure can also shorten the life of your tires, and driving at high speeds can also increase the chance of a puncture. Therefore, it is necessary to check the tire pressure regularly, up to once every two months. If there is a tire pressure monitor, you can check it directly.

If tire pressure monitoring is not available, each tire should be measured manually using a tire pressure gauge.

5.Some sensor data is incorrect, such as water temperature sensors and oxygen sensors. The sensor is not completely damaged, but the data is inaccurate and the fault light does not come on, so it is difficult to find out if the data stream is detected by the computer.

6.Too much carbon deposits in the car. Where the carbon is deposited are the throttle, injector, air intake, and piston top.

Excessive carbon deposits anywhere can lead to incomplete combustion, which in turn leads to increased fuel consumption. There are no obvious faults in the first five items, and the driver will not have any abnormal sensations. It is only when the carbon deposit is too large that the failure will be obvious.

Common problems include shaking, weak acceleration, and difficulty ignition. Therefore, when encountering these faults, we must first consider the problem of carbon deposition and repair it in time.

With the continuous development of social economy, the level of the national economy continues to improve, people's consumption demand is also increasing, and the requirements for clothing, food, housing and transportation are becoming more and more stringent. However, the use will be accompanied by problems, many car owners began to find that after a period of use of the car, fuel consumption suddenly increased, what is going on? Maintenance Master:

It could be due to these reasons.

For the sudden increase in fuel consumption of the car, the first point is to start from the gasoline itself, as the driver of the car, we have a deep understanding that when your gasoline is full and almost exhausted, your driving feeling is obviously different. On the other hand, the owner does not know much about the car, and accidentally chooses too thick engine oil, which directly leads to a reaction, which increases the friction to the car parts, which is counterproductive. Therefore, car owners are advised to choose regular repair and maintenance shops as much as possible in case they spend money to buy unpleasant.

The second point, which may be because of one part of the car that is at fault, is the spark plug. The spark plug acts as a hub to power the car, and if the spark plug is blocked, it will directly cause the gasoline to not burn completely, and your fuel consumption will continue to increase. How do you determine if there is a relationship between increased fuel consumption and spark plugs?

You can remove the spark plug and check it regularly to eliminate the problem in time. The spark plug is not like an antique, the more the plate is more flavorful, it is something with a certain service life, so the owner should also replace the spark plug regularly.

The third point is that the car as a means of transportation, more or less will have a certain load purpose, you may move you will fill the car, or carry too many people at one time, but the continuous increase in load will also lead to an increase in car fuel consumption to a certain extent. There are also some unqualified car owners may have obtained a driver's license through a quick way, and run rampant on the road, which leads to more or less sudden braking in the driving process, one step at a time, and constantly braking to start, which is also the reason for the increase in fuel consumption of the car. The above three points may be the culprit of the increase in fuel consumption of automobiles.

Solutions to the increasing fuel consumption of automobiles:

1. Spark plug:

As an important part of the ignition system, if there is a problem, it will affect the normal operation of the entire ignition system, and after the spark plug is damaged, it will affect the fuel consumption of the car, the working environment of the spark plug is bad, the frequency of failure is high, and after the spark plug fails, there will be no force for refueling, idle shaking when driving, and fuel consumption increases.

2. Battery:

The car battery controls most of the circuit system in the car, the car battery has a problem, when starting, the ignition energy becomes low, the fuel consumption soars, although the battery is not broken, but there may be a decline in performance, so it is recommended that the owner replace the car battery in time to avoid the increase in fuel consumption when driving.

3. Air filter:

During driving, if the air filter is blocked and the engine air intake is not smooth, the fuel consumption of the car will increase, and the car engine will be mixed with dust and impurities during the working process, and the engine in this environment may appear abnormal wear and tear, which is more likely to produce carbon deposits.

4. Oxygen sensor:

The oxygen sensor of the car is located on the exhaust pipe of the engine, which controls the amount of oxygen and the proportion of fuel of the engine, if the oxygen sensor of the car is deviated, the fuel consumption of the car will rise, and the oxygen sensor of the general car needs to be replaced in time after 8-110,000 kilometers.

The reasons for the high fuel consumption of automobiles are mainly in the tires, engines, oxygen sensors, and a control fiber disturbance unit of the engine, etc., and the specific solutions are as follows

1. Tire:

Tires are easier to inspect, so you should check your tires first. If the tire pressure is insufficient, the fuel consumption will increase. If there is no problem with the air pressure, then check the degree of wear and tear of the tire, when the tire is severely worn, there will often be signs of slippage, which will also increase fuel consumption.

2. Engine:

If there is a lot of carbon deposition in the engine in the short term, it will also cause high fuel consumption of the car, which is likely to be the use of substandard oil. The solution is to add a certain amount of detergent when refueling, if the effect is not obvious, it means that there is more carbon in the engine, which has to be handed over to the 4S shop or maintenance shop, and the technician will clean the carbon deposit in the engine.

3. Oxygen sensor:

As an internal control unit of the car, the oxygen sensor is mainly used to monitor the engine oil and gas ratio, once damaged, it will cause the engine oil and gas ratio to be out of balance, and the fuel consumption will inevitably increase abnormally, after the oxygen sensor is damaged. When the vehicle is driving, the exhaust pipe will exhaust a darker exhaust fume. At this time, the oxygen sensor should be replaced as soon as possible.

4. A control unit of the engine:

Although the engine's electronically controlled single-split Hu Yuan is highly reliable, it is inevitable that there will be failures in those cars that have a long service life. If one of the control units fails, it is likely to increase fuel consumption, accompanied by poor dynamics and dark exhaust gases.

There are three reasons for the high fuel consumption of automobiles, namely, the car itself; the second is personal driving reasons; The third is external factors such as weather.

First, the reason for the car itself:

1.Damage to the car's oxygen sensor;

As the internal regulation unit of the car, the key to the oxygen sensor is to monitor the oil-gas ratio of the engine. Once damaged, it will cause an imbalance in the oil-gas ratio of the engine, and the fuel consumption will definitely increase suddenly.

2.The three filters haven't been changed for a long time;

During car use, the three filters must be replaced regularly. If it is not replaced for a long time, it will become dirty and greasy, which is related to use, and will send incorrect information to the engine control unit, resulting in insufficient fuel combustion and increased carbon deposits in the engine.

Two. Reasons for driving:

1.Abnormal tire pressure or replacement of oversized tires;

When the tires are underinflated, it will affect fuel consumption. When the tire pressure is too low, the contact area between the tire and the ground will increase, the driving resistance will be greater, and the car will naturally become more waste oil.

2.When idling for long periods of time, do not turn off the engine or ignite frequently. Every time the engine is started, the amount of fuel injected by the computer will be quite large, so starting the engine frequently for a period of time will definitely increase the fuel consumption of the car.

Three. External factors such as weather:

1.The car increased the load for no reason.

Casually adding a large fence, rear wing, winch and luggage rack to your car will also increase your car's fuel consumption.

2.The windows are fully open on hot days.

People who turn on the air-conditioned car in the summer will naturally feel much more comfortable, but as the engine load increases, the fuel consumption also increases.
