The new car has run 13,000 kilometers, what is the reason why it feels more and more fuel intensive?

For automobile fuel consumption, it is a topic of great concern to many consumers, because the higher the fuel consumption of the car, the economic cost borne by the owner is very high, so consumers often have to choose the kind of car with low fuel consumption and strong power. And for the new car ran 13,000 kilometers, the owner feels more and more will swim because the owner did not maintain the car in time, when the car has traveled so many kilometers after the car throttle and the spark plug of the car have serious carbon deposit problems, this time will increase the fuel consumption of the car will also reduce the power of the car.

First, the reason for the fuel consumption of automobiles is that the throttle is seriously decarbonized.

It is necessary to know that the engine must do work through fuel combustion, and the medium required for combustion is air, so the throttle is located at the intake of the engine end, and at the same time controls the air intake of the engine. The serious carbon deposition of the throttle valve will directly affect the fuel consumption of the car. <>

Second, the serious carbon deposition of the spark plug will also lead to the increase of automobile fuel consumption.

The spark plug is the most important part of the automobile ignition system, if there is no this accessory, then the car can not be ignited normally, and when the spark plug carbon deposition is serious, it will also lead to an increase in the carbon deposition of the car, and it will also be accompanied by a phenomenon of abnormal engine shaking, so the owner finds that the fuel consumption of the car increases and must maintain the car in time, so as to make the engine work condition better and better, and also reduce the fuel consumption of the car. <>

3. Summary. Generally speaking, when the new car has traveled 13,000 kilometers to maintain the car, and the owner feels that the reason for the increasing fuel consumption of the car is that the throttle and spark plug are seriously decarbonized, but the car fuel consumption in addition to the car itself in addition to the car condition, and the driver's driving behavior is also very related, if the owner violently drives the car will also directly lead to the increase in fuel consumption. <>

The spark plug is aging, the fuel consumption has increased too much, the spark plug must be replaced in time, the internal carbon deposit in the engine is too much, and it may be because the air filter is too dirty, and the tire pressure is too low or too high.

The reasons for the increasing fuel consumption of the car are: engine carbon deposit, spark plugs need to be replaced, oxygen sensor is broken, the "three filters" are not replaced in time, the idle time is too long, and the tire pressure is abnormal.

It may be caused by serious carbon deposits in the engine, or it may be caused by abnormal tire pressure.

There are several factors that can help reduce fuel consumption by running at high speeds:

1. The speed limit of the high-speed is very close to the economic speed of the car (about 80-100 per hour), which will keep the car within the ideal range of economic fuel consumption.

2. When the car is driving at high speed, the engine will inevitably increase the speed because of the speed problem. This will cause some of the carbon deposits generated by the low engine speed when driving at low speeds before, resulting in effective cleaning in the engine, more full combustion, and some power will be increased.

Because it is fully combusted, the amount of fuel used will be relatively reduced, but the power will be stronger.

3. Because driving at high speed, the parts of various parts of the car can be in an ideal "running-in" state, which will invisibly accelerate the smoothness of the parts of the car without wasting excess power.

4. Because there is no traffic light in the city at high speed, on the other hand, the car can maintain power better, and the engine and other parts of the car can always be in a good and smooth working state to avoid excessive fuel consumption caused by stopping and walking. And the most fuel-efficient when driving at a normal constant speed.

To sum up, after the car finishes pulling the high speed, the internal resistance is reduced, and the fuel combustion is more sufficient, which leads to the reduction of fuel consumption after the high speed.

The more common reason is that there is too much carbon deposit, find a section with fewer cars, raise the speed of the car and step on the accelerator hard, and it will be better to pull the carbon deposit.

1. Pay attention to oil products and clean up carbon deposits.

Our country's oil products have been complained about, but not eggs, as ordinary people, we can only pay more attention, don't be greedy for a small bargain, or can add some quality and pass the quality of the oil.

2. Replace the spark plug regularly.

Don't underestimate such a small spark plug, its function is to use high-voltage electricity to generate an electric spark 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.

The life of ordinary spark plugs is only 3-50,000 kilometers, the life of iridium spark plugs is about 5-80,000 kilometers, and the life of platinum spark plugs can reach 100,000 kilometers.

3. Check tire pressure and tire wear frequently.

This is easy to understand, if the tire pressure is too low, the friction between the tire and the ground will increase, the drag will increase, and the fuel consumption will increase. If we find that the gliding distance of the car is significantly reduced in our daily driving, we should check whether the air pressure of the tires meets the air pressure standard.

It can be seen that more and more models now have the configuration of tire pressure monitoring, which is convenient for you to grasp the situation in real time, and we should praise these conscientious manufacturers. Also remember to check the degree of wear and tear of the tires, if the tires are severely worn, there will be frequent slippage and fuel consumption will also increase.

4. Replace the oxygen sensor in time.

Simply put, 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.

Maybe you have been running at a low speed, and you generally need to pull the speed at high speed within kilometers, and now you may not be able to pull out the ...... for 2w kilometers

The reasons for the lack of power of the car are: 1. Failure of the oxygen sensor; 2. The quality of gasoline is not up to standard; 3. The air leakage of the inlet pipe leads to the mixture being too thin; 4. The fuel pressure is low, the injector is blocked, and the fuel filter is blocked; 5. The signal of the pressure sensor and the throttle position sensor is abnormal; Zi Jingsui 6, the sensor signal is abnormal, resulting in the ignition timing is inaccurate, and the ignition is too late; 7. Weak high-voltage sparks due to poor spark plugs, igniters or high-voltage wires; 8. The throttle is dirty; 9. The exhaust gas recirculation system works poorly; 10. The exhaust pipe is blocked; 11. The cylinder pressure is low; 12. Turbocharging system failure. 1. Ignition reasons:

The spark plug gap does not conform to the standard draft, the distributor fire divider head is damaged, the ignition sequence of each cylinder is out of order, the ignition timing is incorrect, the high pressure fire is weak, and the electronic igniter and pulse signal generator are faulty; 2. The main reasons for the valve distribution mechanism: the valve distribution phase is inaccurate, and the valve sealing is not tight; Valve springs become weaker or shorter; 3. Causes of fuel supply: dust or moisture in the fuel pipeline, faulty gasoline pump, improper assembly and adjustment of carburetor float, blockage of air filter, defective or improper adjustment of emission control system, and blockage of exhaust system.

It must be a problem with gasoline, and it has a lot to do with gasoline, and it should be replaced immediately to protect the engine and form of the car.

It may be that the gasoline has entered the water, so it will not be easy to use, these are all things that need to be paid attention to, and choose a better gasoline in the future.

It must be that on the day of the steam clear and smart oil, you should immediately replace the gasoline of Wuyou, so that there will be a good form, otherwise it will directly affect your future and results.

Summary. Hello, 1. The run-in degree is not enough for the new car just bought, because the various parts in the engine of the new car have not been fully run-in, the gap between the various parts is relatively small, and the running resistance of the engine is larger than that of the run-in car. Therefore, you can patiently run in and wait until after the first warranty to see if there will be a change in fuel consumption.

If the fuel consumption after the break-in period is greater than before, it is possible that the fuel injector and throttle valve are too dirty and have not been cleaned in time. 2. The main reason for the poor oil circuit when the engine has too much carbon deposit, and the reason for the excessive carbon deposit of the engine in the short term is mainly the use of unsuitable oil. 3. Improper driving habits, if you hit the accelerator or frequently step on the brakes during driving, the fuel consumption of the car will increase, and start according to the normal rhythm, refueling, and shifting, you can save a lot of fuel over time.

In addition, keep track of the following distance between you and the car in front of you and minimize unnecessary braking movements.

2. The main reason for the poor oil circuit caused by excessive carbon deposition in the engine and the reflux of the engine is the main reason for the excessive carbon deposition in the engine in the short term, mainly due to the use of unsuitable oil. 3. Improper driving habits, if you hit the accelerator or frequently step on the brakes during driving, the fuel consumption of the car will increase, and start according to the normal rhythm, refueling, and shifting, you can save a lot of fuel over time. In addition, keep track of the following distance between you and the car in front of you and minimize unnecessary braking movements.

4. For the owners of the new car who just bought a new car, many people like to put such and such decorations and appearance parts on the Yuchun car, and even more simply move the office and home to the car, which increases the fuel consumption of the car. It is reported that the fuel consumption of the vehicle will rise accordingly when the self-weight of the vehicle is destroyed and demolished, so it is necessary to minimize the load of the car and clean up the items that are not often used in the trunk in time. 5. The air filter element is too dirty in the process of use, the air filter must be replaced regularly, if it is not replaced for a long time, they will become dirty, affect the use, and transmit wrong information to the engine control unit, resulting in insufficient fuel combustion and increased engine carbon deposit.

6. Abnormal tire pressure According to statistics, the tire will affect the fuel consumption when the tire is not inflated, and when the tire pressure is too small, the contact area between the tire and the ground increases, and the driving resistance is greater, so the vehicle will naturally be closed with more waste oil.

Summary. Car fuel consumption is getting higher and higher, probably for the following reasons:

1. Insufficient tire pressure. Insufficient tire pressure will cause the contact area between the tire and the ground to become larger, and the friction force will increase, that is, the driving resistance will become larger, and the fuel consumption will increase.

2. There is a problem with the ignition coil. If there is a problem with the ignition coil, it will cause some cylinders to not operate and the power will decrease, but the oil that should be sprayed will still be sprayed, but it will not play any role, so the fuel consumption will rise. 3. Excessive carbon deposition in vehicles.

In any place, the fuel consumption of the new car will be higher than usual during the run-in period, because the friction resistance of the new parts is relatively large, so the fuel consumption will be relatively high.

The fuel consumption of the car is getting higher and higher, and it may be due to the following reasons: 1. Insufficient tire pressure. Insufficient tire pressure will lead to a larger contact area between the tire and the ground, and greater friction, that is, greater driving resistance, and higher fuel consumption.

2. There is a problem with the ignition coil. If there is a problem with the ignition coil, it will cause some cylinders to not operate and the power will decrease, but the oil that should be sprayed will still be sprayed, but it will not play any role, so the fuel consumption will rise. 3. There are too many disadvantages of vehicle carbon deposition.

In any place, the fuel consumption of the new car will be higher than usual during the run-in period, because the friction resistance of the new parts is relatively large, so the fuel consumption will be relatively high.

Hello! To put it simply, because most of the vehicles in the city are driving at medium and low speeds, the valve and other parts will produce carbon deposits over time, and after running through the high speed, these carbon deposits have a certain chance to burn off, and the combustion of the transmitter is more sufficient, and you will also experience that the car is still strong, right? The power is used more fully and the internal resistance is reduced, which leads to the fuel economy of the vehicle.

The fuel consumption of the new car must be relatively high as soon as it is picked up. Generally, the fuel consumption of high-speed cars is relatively low.
