Why does the car consume more fuel the more you drive? Why does the car cost more fuel the more it d

Fuel consumption refers to the fuel economy index of the car when driving at a 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. And now many cars are driving more and more fuel-consuming, so let's take a look at why today's cars are driving more and more fuel-intensive.

Third: too much carbon deposits in the engine.

Causes of excessive carbon deposition in the engine in the short term. The main reason is that unsuitable oil products are used. This is more likely to happen after returning from a long drive or lending the vehicle to someone else.

Drive long distances. Fuel will definitely be added from place to place, and even if it is the same grade of fuel, the quality of the oil will vary from place to place, so it is likely that the wrong oil has been misused. It is more difficult to control the quality of the added oil when the car is lent to others.

Second: Severe tire wear or low tire pressure.

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. What is our normal tire pressure?

Open the fuel tank lid of your own car and it will be written on it. (Varies from car to car) is generally normal tire pressure around the right, and it can be appropriately reduced in summer. We can see 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.

First: oxygen sensors.

Oxygen sensor will produce loss to fuel consumption, oxygen sensor is used to detect the content of oxygen in the exhaust gas discharged by the engine, if the oxygen content is detected is higher than a certain value, it means that the fuel combustion is incomplete, and the air intake of the combustion chamber needs to be adjusted to achieve the air-fuel ratio required for complete combustion, so that the fuel is fully combusted, the efficiency is low, and the fuel consumption is high.

Causes and solutions; 1. Excessive carbon deposition in the engine: excessive carbon deposition in the valve and intake pipe is the most common reason for the decline of engine power.

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.

We all know that the car is depleted, and it will naturally affect its performance after a long time, and fuel consumption is naturally very concerned by many car owners.

The car is becoming more and more fuel-intensive, and it is just that it is broken.

Fuel saving tip 1: Warm up the car in moderation.

Most car owners have a good habit of warming up their cars in the morning. However, just wait for the engine speed to drop to normal or for the water temperature to rise to normal. It's like having trouble with your wallet.

In summer, the owner can drive in gear about half a minute after the vehicle starts, and then drive normally after driving a certain distance in 1st gear. When driving on the road, do not drive fast before the water temperature of the car is normal, so as to reduce the wear and tear of the car and reduce fuel consumption. And in winter, 2 minutes of hot car is enough.

Fuel saving cheats 2: Don't hang D gear while waiting.

When encountering a long wait, it is recommended that the owner can choose to turn off the engine. The correct approach should be to hang the "N" gear (commonly known as neutral) when waiting for the traffic light. The consequence of this is that fuel savings" around.

Fuel saving cheat three: thoroughly implement vehicle lightweight.

Don't think of the car as your home, the reason why the interior of the car is completely dismantled is because these unnecessary equipment take up a lot of weight. It's the same with everyday cars.

Fuel saving cheats 4: Driving with the window closed can save fuel.

When the air conditioning system works, it consumes part of the engine's power. In order to save fuel, some drivers take the method of turning off the air conditioner and opening the windows for ventilation at high speeds.

Fuel saving cheats five: daily maintenance should be paid attention to.

Maintain the vehicle according to the regulations, change the oil on schedule, and avoid using low-standard oil. Replace the air and air conditioning filters on a regular basis to reduce the suction assistance of the engine and compressor. Second, adjust the tire pressure to the optimal value, and control the tire pressure in between.

As long as one tire is 40 kPa less inflated, the tire will reduce its life by 10,000 kilometers and increase the total fuel consumption of the car by 3%. If the tire pressure is reduced by 30%, the car's fuel consumption will increase by 5%-10% when the car is driving at a speed of 40 kilometers per hour.

Fuel saving tip 6: Don't rush to speed.

Rapid acceleration and sudden stop in driving, although it is very chic and majestic, but the price is that fuel consumption has increased by 2 or 3 times compared with driving at a constant speed. The optimal "economic speed" for an average car is 60 to 90 kilometers per hour. On the highway, it is best not to exceed the speed of 100 kilometers per hour for the general four-cylinder car.

At 120 km/h, it will consume 20% more fuel than 100 km/h.

Because the car gradually began to deteriorate as he aged**, the function of his fuel tank gradually began to deteriorate.

I think it's because the car will gradually deteriorate over time.

Therefore, there will be such people who are also the best in many aspects and costs.

Why does the car cost more fuel the more you drive? The reason is very simple, the old driver teaches you a trick to get it done!

The more the car drives, the more fuel is consumed, it is broken, it used to be 5 cents, and now it runs 1 yuan.

I think it's probably because the longer the car is driven, the more fuel the engine consumes.

Nowadays, cars are an indispensable means of transportation for people to get around, and many homes are equipped with cars. However, it is not a question of buying a car once and for all, it also includes parking fees, maintenance fees, insurance premiums, etc. And most importantly, there is also the cost of fuel.

With the increasing cost of fuel, many car owners are screaming that they can't afford it, and natural fuel consumption has become a hot topic for the majority of car owners. Many car owners say, why is the fuel consumption getting higher and higher when driving? So what is the reason for the high fuel consumption when driving?

1.Anomalous spark plugs.

Spark plugs work in car ignition. The high-voltage pulse shock breaks through the air between the two stages to produce an electric spark that ignites the mixed oil and gas in the gas cylinder. Therefore, spark plugs are very important for starting the engine.

If the car is good for a long time, the internal environment of the engine cylinder is slowly deteriorating, so the spark plug is more and more prone to abnormal changes in color, clearance, shape, etc., resulting in early or lagging ignition, incomplete combustion and even detonation. When the spark plug is abnormal, the mixture in the combustion chamber cannot be completely ignited, which eventually leads to insufficient power and increased fuel consumption, so don't forget to maintain the spark plug when you usually maintain the car.

2.Severely worn tires Insufficient tire pressure.

As we all know, tires are the only carrying point for cars to contact with the ground, and the power of the car is also closely related to tires. The power output of a car's engine depends on the grip of the tires being converted into the power of the car. If the tire pattern is worn too severely, the grip will be reduced, the power will be obviously insufficient, and even the phenomenon of slippage will occur, and the fuel consumption will naturally increase.

As the bearing point of the tire, if the tire pressure is insufficient, the contact area between the tire and the ground will increase, the frictional resistance will also increase, and the fuel consumption will also become higher.

3.Aging of the oxygen sensor.

Oxygen sensor aging is often caused by the high local surface temperature of the sensor element. As an important part of the electronically controlled fuel injection engine, the oxygen sensor is used to detect the oxygen concentration of the sock beat in the exhaust, and then sends a feedback signal to the ECU of the friendly shed car to adjust the fuel injection volume in real time, so that the air-fuel ratio is always kept around the theoretical value. Once a failure occurs, it will not only exceed the emission standard, but also worsen the working condition of the engine and increase fuel consumption.

4.The nozzle is clogged.

The condition of the injector has a direct impact on the performance of the engine. If the injector is clogged, it may be that carbon deposits from the engine are depositing on the injector, or impurities in the fuel are clogging the injector channel. If the injector is blocked, it will not only directly reduce the power of the car, but also accelerate the wear of the cylinder barrel and piston rings, resulting in unstable idling, increased fuel consumption, poor acceleration, difficult starting, excessive emissions, and even serious damage to the engine.

Therefore, it is recommended that car owners clean the injectors regularly. If the vehicle is in good condition and the fuel quality is good, it should be washed once at about 60,000 km, and if it is normal, it should be washed once at around 30,000 km.

Millions of car purchase subsidies.

As the saying goes, it's easy to buy a car and it's hard to maintain a car, after buying a car, calculate the cost of a month to spend on maintaining a car, which is really a lot. One of the problems is that many car owners have faced, the more the car drives, the higher the fuel consumption, so what is the reason for the high fuel consumption of the car?

1. The tire pressure is low. The tire is the only part of the car that can contact with the ground, so if the tire pressure of the car is too low, it will lead to an increase in the contact area between the car and the ground, which in turn will increase the driving resistance, so it will naturally lead to high fuel consumption of the car. The tire pressure of the car can be kept at a fixed level, and if it is summer, it can be lowered according to the situation.

2. Spark plug failure. If the spark plug of the car is carbon deposited or damaged, resulting in insufficient ignition energy, resulting in uneven gas combustion in the car and abnormal fuel injection system, then it will definitely lead to high fuel consumption of the car. If you find that the speed of the car decreases, and the fuel consumption increases the more you drive, then you can check the spark plug and replace it with a new one in time.

Oxygen sensor, check injectors, spark plugs.

It is necessary to clean up the carbon deposit and oxygen sensors, and check whether there are any problems with the fuel injector and fire nozzle.
