What is the situation of the car that has been particularly fuel hungry recently?

Recently, the car has been particularly fuel-hungry for the following reasons:

1. If there is a problem with the electronic control system of the engine, the concentration of mixed gas is too large, which will increase the fuel consumption of the car. If the vehicle is in a cold start.

The reason for the increase in fuel consumption is that the electronically controlled engine has the function of cold start and concentrated mixture, which will increase the fuel consumption of the car.

2. Clean the throttle.

Resulting in high fuel consumption, because the throttle valve is not washed for a long time, the wear of the throttle valve and throttle arm increases, and after cleaning the throttle, the gap will become larger, and the fuel consumption will naturally increase. However, this situation will return to normal fuel consumption after a period of cleaning.

3. Engine carbon deposits.

Too much is a common cause of sudden increase in fuel consumption, and too much carbon will lead to insufficient fuel burning, so car owners need to clean up the carbon deposits regularly.

4. Ignition coil.

If there is a problem with the output high pressure, the ignition will not ignite, and the natural fuel consumption will increase.

5. Spark plugs.

It is mainly responsible for igniting the engine, which is equivalent to the heart of the engine, and its damage or aging will increase fuel consumption.

6. If the inside of the car injector is seriously worn or damaged, the fuel consumption will increase.

7. After the cooling system of the engine has problems, the engine temperature will be very low, the viscosity of the oil will increase, the resistance during mechanical operation will increase, and the fuel consumption will increase.

8. After the ventilation of the vehicle fuel tank does not work, the vapor of the fuel will leak, which will also cause the fuel consumption to increase. <>

Tips to save fuel

1. Reduce the load on the car.

The more debris you put on your car, the heavier your car will be, and your fuel consumption will increase. Therefore, in the process of daily car use, try not to pile unnecessary debris on the car, which can effectively save fuel.

2. Prevent the engine from running dry.

When the engine is running at idle rpm, gasoline consumption is slow, so if you are waiting in line or waiting for someone, try to avoid running the engine at idle rpm to effectively save fuel consumption.

Solution: Find a professional auto repair personnel to help clean up the carbon deposit, and check whether the spark plug needs to be replaced.

2. The fuel supply system is not smooth: check the fuel supply system, whether there is blockage or gas resistance in the fuel pipeline, whether the gasoline pump is working normally, whether the oil level height of the carburetor float chamber meets the specified requirements, whether the air filter is blocked, whether the exhaust system is blocked, etc.

Solution: It is recommended to dredge the fuel supply system.

3. Poor tire pressure of automobiles: Poor tire pressure is also one of the reasons for the decline of engine power, especially when the tire pressure is insufficient and the number of people is large.

Solution: Therefore, when the tire is inflated, it must be filled enough, and it should be filled according to the tire pressure gauge marked on the body.

4. Air filter blockage: air is one of the power of the engine, if the air filter is not cleaned in time for a long time, the lack of air volume will cause the combustible mixture to be too thick, so that the engine power will decrease; In the case of a vehicle with a turbocharger, the failure of the supercharger will also cause the engine power to be reduced or weakened.

Solution: It is recommended to clean the air filter.

5. In addition, the efficiency of the spark plug is reduced and the water temperature is too high; There was a knock in the cylinder; Reasons such as excessive oil temperature in the engine can also affect engine power.

Solution: It is recommended to go to a professional repair station for inspection and repair.

6. The car is added to the gasoline of poor quality (such as too many impurities such as mixture), which is also the reason for this failure in many cars, whether it is a new car or an old car. Because there are too many impurities in the gasoline composition, it is easy to cause the generation of carbon deposits, and it will also affect the blockage of the oil circuit, thereby causing the power to decline due to the unsmooth oil supply.

7. The working principle of the throttle valve is to control the air intake volume of the engine, and its opening angle has a standard value, if it does not reach this standard value, it will affect the abnormal amount of fuel injection, resulting in power decline or power instability.

Solution: It is recommended to clean the throttle valve by the way when carrying out car maintenance, and check whether the air filter needs to be replaced;

8. The function of the belt is to drive the engine, compressor, generator, and water pump to run the transmission, if the belt is aging and there is a phenomenon such as slippage or cracks, it will directly affect the power of the car.

Solution: During maintenance, you should also call the maintenance master to help check whether the belt is good.

When the tire pressure is too high, the tire pressure is too high, which will reduce the friction and adhesion of the tire, affect the braking effect, and also affect the life of the tire; It will also lead to a decrease in tire durability, which is easy to cause punctures; In addition, accelerate the local wear of the tread pattern of the tire tread, reduce the life of the tire, and the vibration of the body will become larger, which will indirectly affect the life of other parts.

Another situation is that the tire pressure is too low, which is a big reason for the increase in fuel consumption.

When the tire pressure is too low, the steering wheel will become heavy, easy to deviate, and at the same time, it will also cause damage and abnormal wear of the bead part, and the tire strength will decrease; The biggest factor is that the friction between the tire and the ground increases exponentially, which will cause the tire temperature to rise sharply, the tire to become softer, the strength to drop sharply, and the vehicle to drive at high speed, which will also lead to a puncture.

However, most cars are now equipped with tire pressure monitoring devices, and cars that are not equipped with this function should pay attention to it, and check the tire pressure in time when some situations such as the steering wheel becomes heavy to prevent the harm caused by low tire pressure.

Causes of carbon deposition in spark plugs and intake and exhaust valves.

Due to oil or driving habits, abnormal combustion such as deflagration and surface ignition in the cylinder will increase the carbon deposition of the spark plug and intake and exhaust valves, and the carbon deposition or aging of the spark plug will reduce the ignition energy and ignition stability, resulting in an increase in fuel consumption.

Carbon deposition in the intake valve will lead to insufficient air intake, decrease in charge coefficient, insufficient combustion and increase fuel consumption, and carbon deposition in the exhaust valve will lead to insufficient exhaust and an increase in residual exhaust gas in the cylinder, which will indirectly affect the intake process.

Generally, this situation will occur when the car runs to 20,000 to 30,000 kilometers, so we should pay attention to check whether there is this phenomenon when we maintain the car at this time, and if there is, we must clean it.

Replacement of "three filters".

Three filters: air filter, oil filter, gasoline filter.

These three pieces need to be replaced regularly, if they are not replaced for a long time, they will become dirty, the filtration capacity will decrease, the fuel combustion is not sufficient, and the fuel consumption will naturally increase, so the owners should pay attention to the replacement time.

Inaccuracy of various sensors.

This is rare, but it is important to be careful.

When the oxygen sensor is inaccurate, the air-air mix ratio becomes inaccurate, resulting in inadequate combustion. Once the water temperature sensor is misaligned or there is a problem with the electronic fan circuit, the electronic fan will run uninterrupted, causing the water temperature to drop, and the effective power of the engine will decrease, resulting in an increase in fuel consumption.

Insufficient cylinder pressure.

Generally, because of the poor air tightness of the cylinder, this situation usually appears in the car that has driven two or three hundred thousand kilometers, which will lead to a decrease in the energy conversion efficiency of the engine and an increase in fuel consumption.

Many people see in the movie that they slam the throttle before starting, but in fact, this is very undesirable and will lead to insufficient fuel burning, resulting in increased fuel consumption.

Frequent braking. Frequent braking will consume the kinetic energy of the car itself, and then frequent acceleration at the start, this stage is when the engine load is large, fuel consumption will also become higher, and the longer the starting acceleration time, the higher the fuel consumption will become, so it is necessary to slow down in advance when using the car in daily life, do not brake frequently, which will also increase fuel consumption.

There are several reasons for this problem.

First: driving habits are not good, drill when you see empty, stop and brake urgently, hang low gear and open high speed and other habits will lead to a car is very fuel-efficient, if you want to be more fuel-efficient, you can try to maintain a constant speed, relying on inertia brake lights.

Second: engine carbon deposits, the engine will also cause high fuel consumption after carbon deposits, you might as well buy carbon cleaning car supplies to clean up the carbon deposits of the engine, so that the car is not so fuel-intensive.

Third: the tire pressure is low, the tire pressure of the wheel is too low and the wheel inflation is not enough will also cause the car to be very fuel-intensive, you may wish to detect the wheel inflation problem when driving, and the tire pressure can also be detected by the instrument, and the timely inflation of the wheel will reduce fuel consumption.

Fourth: the trunk is too heavy, the trunk will put too many items will also make the car very fuel-intensive, clean up the trunk items in time to throw some unnecessary things down, for the car to shoulder it naturally is not so fuel-intensive.

Fifth: engine wear and spark plug failure will also cause the car to cost fuel, you can check whether your car has these two problems.

Sixth: If the car is not hot, not only will the engine be worn out before driving in winter, but also the car will be very fuel-intensive. Therefore, it is best to warm up the car before driving in winter, do not drive in a hurry but idle in place for a minute, and after normal driving, you should also keep a low speed first, and then slowly stop the speed.

If none of these are available, then you can see if the oxygen sensor is broken, the clutch is slipping, and so on.

Moreover, after a few years of use, the engine wears out, and the mechanical group is aging, and the car will consume more and more fuel as it drives. Usually develop good habits, regularly go to the 4S shop for maintenance, and clean up the engine carbon deposits will reduce fuel consumption

The first reason for answering is poor driving skills, the same car, different people driving, the fuel consumption of the car is also different. Only by improving the level of driving can we solve the problem of high fuel consumption caused by driving technology. The second reason is that there is a problem with the spark plug and high-voltage line of the gasoline vehicle, which causes the ignition circuit to be abnormal, and the problem of high fuel consumption can be solved by replacing the parts.

The third reason is that there is a problem with the braking system, the brake pads do not return to their positions, and the driving resistance increases.

Question: The spark plug was changed.

A sudden increase in fuel consumption is usually a problem with these three components.

Causes of high fuel consumption in automobiles and how to solve them:

1. Reason for high fuel consumption of automobiles: tires. 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 tires, when the tires are severely worn, there will often be signs of slippage, which will also increase fuel consumption.

2. The second reason for the high fuel consumption of the car: the 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. The third reason for the high fuel consumption of automobiles: 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. Reason 4 for high fuel consumption of automobiles: a control unit of the engine. Although the engine's electronic control unit is highly reliable, it is inevitable that it will fail in those cars that have been used for a long time.

If one of the control units fails, it is likely to increase fuel consumption, accompanied by poor dynamics and dark exhaust gases.

1. Change your driving habits, increase fuel consumption, and first consider whether it is the reason for the bad driving habits. For example, habits such as drilling, emergency stop and brake, and low-gear high-speed driving will lead to increased fuel consumption of the car. If you want to save fuel, practice good driving habits.

You can try to maintain a constant speed and rely on Yanhui inertial braking. 2. Clean up the carbon deposit of the engine, if the engine produces carbon deposits, it will cause increased fuel consumption. In this case, you can choose to use car products to clean the carbon deposits of the engine.

3. Inflating the wheels in time The tire pressure of the car is too low, and the insufficient inflation of the tires will also cause an increase in fuel consumption to the car. Therefore, check the tire pressure in time and inflate the wheels in time. 4. Reduce the weight of luggage in the trunk, if you put too much luggage in the luggage, it will also increase fuel consumption.

Clean your suitcase in a timely manner, throw away unwanted things, and lighten the load on your car.

There are many reasons for this. 1.It's time to change the oil filter or spark plug.

2.Insufficient tire pressure or aging tires.

3.It's cold. High fuel consumption. It's cold. The oil does not conform to the labeling.

4.Gasoline is of poor quality.

5.Recently, the road conditions have been bad, and I have driven a lot of short distances.

6.The throttle is dirty.

7.I haven't driven long distances for a long time, and there is a lot of carbon deposit.

8.There is something wrong with the way you calculate fuel consumption.

There must be something wrong somewhere.

Summary. The third is that the tire pressure is too low, and the friction becomes greater during driving, resulting in increased fuel consumption.

What is the reason why the car is suddenly very fuel-intensive???

Hello, riders.

Generally, if there is no maintenance for a long time, more carbon deposits will lead to higher fuel consumption, which is also a common reason.

The second is that the spark plug gap is too large, resulting in increased fuel consumption.

The third is that the tire pressure is too low, and the friction becomes greater during driving, resulting in increased fuel consumption.

It is recommended that you have time to go to the 4S store for an inspection and regular maintenance.

Hope it can help you and have a happy life! Career is going well!!
