Recently, fuel consumption has risen significantly, how to break

Fuel consumption is most directly related to road conditions and driving style.

In the traffic conditions of urban congestion, even if there is a start-stop function, because it is not cruising under economic fuel consumption, fuel consumption will definitely increase, which is normal.

The impact on fuel consumption is also very important for driving style, and it is often said that there is no fuel-efficient car, only a fuel-efficient driver, and it is not false at all.

The fuel-efficient driving style is to drive at a constant speed as much as possible, avoid rapid acceleration and then sudden braking, and let the efficiency of the engine be applied to driving as much as possible. There should be a prediction of the road conditions ahead, such as the overall slow speed ahead, at this time you accelerate up sharply, and then brake to slow down, the consumption of this power is all eliminated by your brakes, resulting in a waste of power.

Therefore, the most important thing is the driving style, and it is very important to predict in advance, whether it is from the perspective of energy saving or safety!

Hello, fuel consumption then depends on the distance, as well as driving habits.

Hello landlord! Clean up some carbon deposits in the joint door, and pull the car on the better road conditions.

This looks like it needs to be maintained, or the throttle has serious carbon deposits.

Fuel consumption is directly related to driving habits and road conditions. Recently, the weather has been hot, and it is inevitable to turn on the air conditioning in the car, and it is normal for fuel consumption to increase slightly.

In summer, the air conditioner and traffic jams will increase fuel consumption somewhat.

This should be the recent hot weather, the increase in fuel consumption caused by turning on the air conditioner.

Fuel consumption depends on road conditions, driving habits are not absolute, vehicle load is related.

The party that thinks that the fuel-saving side of the gear coasting thinks that when the car is coasting at high speed, the engine will automatically cut off the fuel, and the engine will automatically stop supplying fuel before the engine speed is higher than the "reverse sequence injection point". Models with instantaneous fuel consumption display can pay attention to the fact that in the case of coasting in gear (without stepping on the accelerator), the instantaneous fuel consumption will be displayed as 0, and the coasting in neutral gear will show fuel consumption.

The automatic car is estimated to be wasted, coasting is OK, but do not slide downhill and turning and overtaking, otherwise it will cause traffic accidents because of the brakes, neutral sliding, easy to lose control and affect driving safety, there is no ramp where the inertia speed is limited, idle neutral continuous braking, brake disc is easy to heat, affect braking performance. Sometimes coasting in gear consumes less fuel than coasting in neutral, and it also ensures driving safety.

Therefore, coasting is not fuel-efficient, if it is an AT transmission, coasting will increase the oil temperature, and there are hidden dangers to the transmission and lubricating oil, which is not conducive to the safety of the whole vehicle. For example, in the process of coasting in high-speed gears, in fact, there is no fuel injection, and the instantaneous fuel consumption is O. Coasting, on the contrary, produces idle fuel consumption.

Therefore, the car coasting in high-speed neutral gear will not only not save fuel, but will increase fuel consumption. When coasting in gear, the engine itself will provide a certain amount of pulling, and with the braking, the braking distance of the car will be shortened. Moreover, the neutral coasting car is easy to stall, resulting in the failure of the brake booster drum and the decline of braking performance.

I am a model, Volkswagen CC, the lowest average fuel consumption has run to 100 kilometers per 100 kilometers, do you believe it? Anyway, I don't believe it, it's okay to have a difference of 1L per 100 kilometers between the fuel consumption gauge and the actual fuel consumption. After all, the models are different, the displacement is different, and the weight of the vehicle is different, and the corresponding ideal fuel consumption level is completely different.

It is impossible to uniformly say that the fuel consumption of 100 kilometers is low fuel consumption. No matter how you calculate it, you can't count three barrels of oil, if the oil price is the same as the export, yuan l, and the oil quality is good, no one will calculate the fuel consumption.

Engine parts need to be maintained, so when the fuel consumption is abnormal, you should check whether the engine parts need to be maintained, repaired and replaced in time.

Tires, tire pressure, tire pattern is appropriate, and whether the wear is serious. These can not only directly affect fuel consumption, but also affect driving safety.

Spark plugs, if the spark plugs are used for too long, there will also be an increase in fuel consumption.

It may be that there is carbon deposit, or there may be some small faults inside the engine that cause fuel consumption to increase, and it is also necessary to see if the quality of the oil added recently is the same as usual.

Usually very fuel-efficient, but the main reason for the sudden increase in fuel consumption is because of the engine, at this time the engine must have failed, so there will be such a significant increase in fuel consumption.

Many car owners find that the fuel consumption of the car has increased inexplicably, and they always exceed their budget even if they do not drive a long distance. In fact, there are many reasons for the sharp increase in fuel consumption, and here are several ways to detect cars on a daily basis, so that the majority of netizens can solve the problem of fuel consumption by comparing different situations.

1. The sliding distance of the car is significantly reduced.

Occasionally, car owners will find that the coasting distance of the moving car is significantly reduced, but they don't know where to start. At this time, you can check whether the air pressure of the tire meets the air pressure standard. If the tires are underinflated, the fuel consumption will also increase, as long as the tires are fully inflated at the right time.

2. Check the degree of wear and tear of the tires.

The degree of wear and tear of tires will also affect the fuel consumption of the car, and if the wear is severe, there will often be slippage, increasing fuel consumption. Therefore, new tires can be replaced if necessary.

3. I found that the wheels had abnormal noises.

Problems with the wheels can also affect fuel consumption, so car owners should check whether the bearings and brake system are faulty.

4. Clutch slippage.

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. The owner needs to replace the clutch plates, clutch pressure plate and driving wheel in time.

5. Insufficient cylinder pressure.

Some car owners find that when the vehicle travels twenty or thirty kilometers, the cylinder will have insufficient pressure, resulting in a significant increase in fuel consumption. If such a failure does occur, then the engine needs to be overhauled.

6. When the exhaust pipe emits black smoke and the fuel consumption increases, the carburetor needs to be checked. If the carburetor is too dirty, you can spray the cleaning agent directly into the carburetor intake, if there is still black smoke at this time, then the carburetor can only be disassembled and cleaned.

7. The spark plug is used for too long.

If the spark plug is used for too long, fuel consumption will also increase. Because the spark plug is damaged, the ignition energy will decrease, and the car will slow down the speed, resulting in a significant increase in gasoline consumption. This is where the spark plug should be replaced.

8. Temperature control improvement and thermostat problems.

When the car's temperature switch and thermostat are damaged, there will be an increase in fuel consumption. 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. Replace the part that is in trouble.

What are the reasons for the sudden increase in car fuel consumption? Do you know? The old driver comes to tell you that most of the time it's the reason for people.

If your car is about 30,000 kilometers away and you're still on a flat section of the city, it's time to check the throttle. The throttle valve is connected to the air filter at the top and the engine block at the bottom, which is said to be the throat of the automobile engine.

Some car owners found that after the car was used for a period of time, the fuel consumption increased sharply, which required the car owner to carefully understand the reasons for the increase in fuel consumption. For example, clutch slippage will cause the engine to lose revolutions, resulting in a sudden increase in fuel consumption, the solution is to replace the clutch pressure plate and drive wheel.

There are many reasons for high fuel consumption, which can be caused by excessive carbon accumulation in the throttle valve, idle motor, intake valves, intake pipes, combustion chambers, spark plugs, fuel injectors, etc.

Because these carbon deposits can block the idle channel, the idle motor will be stuck or out of its adjustment range, which will cause low idle speed, unstable idle speed, high fuel consumption and flameout. There are also frequent starts and stops, infrequent gear shifts, and large throttle, which will cause high fuel consumption.

The driving habit of grabbing when you see a vacancy is common in daily driving, especially when the traffic is not smooth, waiting for a red light, and changing lanes: as soon as the adjacent lane is a little vacant, a car here suddenly accelerates and squeezes over, and has to step on the brakes when it passes. After a while, there was a vacancy in the lane here, and he stepped on the gas pedal and squeezed back.

Waiting for a signal, he can accelerate sharply and stop four or five times. This looks very chic, very imposing, and very vibrant, but at the cost of greatly increasing fuel consumption. How much to increase, experts have done accelerated driving fuel consumption tests:

After letting the vehicle drive at a constant speed into the test section, the test driver stepped on the accelerator to the bottom and drove to the end, and found that the fuel consumption increased by 2 3 times compared with the driving at a constant speed after completing the specified distance.

The habit of driving long distances at low speed, which mostly occurs in beginner drivers, also often occurs in people who are easy to get distracted by driving. Three-gear long-distance high-speed driving, than the four-gear normal driving fuel consumption will increase by 10%, and if the second gear instead of the third gear, fuel consumption will increase.

Modern cars have regulations for shifting gears, and the engine speed must reach the specified number of revolutions before allowing the gear to be increased, which is from the perspective of protecting the engine. But some people go to extremes and don't upshift until the engine revs exceed the specified number of speeds, which also results in wasted fuel. Experts believe that:

The low gear and high speed will definitely cost fuel. High-grade and low-speed are definitely fuel-efficient.

Unnecessary high-speed driving, almost every country in the world has a limit on the maximum speed on ordinary roads, the United States is 55 miles (km) and the road in good condition is relaxed to 65 miles (105 km). As a result, U.S. cars and models aimed at entering the U.S. market are designed to consume the lowest possible fuel at 90 km/h. This is what we call the speed of the economy.

Any car has an economic speed, at this speed when driving the most fuel-efficient, below this speed or above this speed fuel consumption will rise, and after a certain speed, fuel consumption will increase significantly. The speed limit on highways in China is 110 km/h, and some sections are allowed to reach 120 km/h. But many people will greatly exceed this speed when driving on the highway, which is neither safe nor economical.

For example, when the Buick GS sedan is 70 kilometers per hour, the fuel consumption is liters; At speeds of up to 120 km/h, fuel consumption rises to liters; If the top speed of 200 km/h is reached, fuel consumption will also increase significantly.

One thing to note is that bad driving habits have a greater impact on the fuel consumption of large-displacement vehicles, because large-displacement vehicles have large power reserves, strong acceleration and overspeeding capabilities, and drivers dare to drive"Make movements", I want to drill when I have time, and I want to overtake when I have a car. The small displacement car has a small power reserve, low acceleration and speeding ability, and the driving has no interest in squeezing the empty space and driving at ultra-high speeds.

There are many factors that affect fuel consumption, driving habits, road conditions, whether there is carbon deposition in the port, etc., general fuel additives, there is really no need, the effect is only a little bit, use fuel modifiers, use good reputation, can completely clear carbon deposits, maintain the engine, I am using this now, my own car before 8 fuel consumption, after a few times to reduce fuel consumption now, although the display table is not accurate, but can reflect is indeed reduced! The power has been improved, the accelerator can feel that the throttle has become lighter when accelerating, and the carbon emission effect is also very good.

<> "Why does fuel consumption suddenly increase?"

When buying a car, many factors that are considered more than the performance of the car itself, I am afraid that it is the problem of fuel consumption. At the same time, automakers will do everything they can to make them as energy-efficient and emission-reduction as possible in order to attract consumers. Needless to say, the problem of fuel consumption is indeed a concern of many car owners, after all, the car with high fuel consumption is raised, and the wallet"Can't afford to hurt"Yes!

If it is the configuration of the car itself, of course, we can't do anything, but if it is because you don't know how to use the car correctly, the fuel consumption of the car is high, then it can't be worth it. Therefore, let's take stock of some bad habits that will lead to increased fuel consumption when driving, and the owner will be encouraged if he has no change!

1.The speed of the car is too fast.

This is because the faster the speed, the more wind resistance has to be overcome, especially in the winter when the wind is strong. Therefore, it is recommended that you generally drive at an economic speed of about 90 kilometers per hour. Too much or too little away from this value will consume fuel.

Therefore, the mismatch between the driving speed and the gear demand is also both harmful and fuel-intensive.

Whether it's low-end high-speed or high-end low-speed. Therefore, it is necessary to make a choice according to the specific driving situation, and cannot rely solely on theoretical experience. And it should be noted that the bad habit of driving with a slam on the gas pedal and overtaking will not only put yourself in danger, but also fuel consumption"The Big Killer"。

2.Carbon deposits.

It is important to know that the large amount of carbon deposited by insufficient combustion of gasoline can also lead to fuel consumption. Then, the problem of preventing the increase in fuel consumption becomes how to prevent carbon deposits while driving. For example, it is easy for cars to produce carbon deposits when driving at low speed and idling for a long time, which proves the seeming appearance of neutral coasting"Fuel efficient"The behavior is actually very undesirable, which will not only affect the normal operation of the engine but also be prone to safety accidents.

In addition, there is also the problem of hot cars that are more concerned in winter, and if it is not handled well, it is also easy to produce carbon deposits. Warmer areas and now are EFI trucks, in fact, there is not much need. It is still necessary to warm up the car in areas with low temperatures, but the time should not be too long, otherwise there will be not only carbon deposition problems but also direct impact on fuel consumption.

Therefore, the correct way to warm up the car is to heat it in situ for about 1 minute, and then warm the car while walking.

3.The heating is turned on the wrong way.

Now that winter has arrived, sitting in a cold car, only the heating can save your life. However, some car owners will hesitate to turn on the heating because they are afraid of higher fuel consumption. In fact, the correct use of heating does not have a big impact on fuel consumption, but indirectly leads to an increase in fuel consumption because the heating is turned on in the wrong way!

This is because some people are used to turning on the heater as soon as they get into the car, but at this time, the heat of the engine is not enough, and the hot air cannot be blown at all; Second, it also delays the warm-up, which leads to an increase in fuel consumption. Secondly, it is not advisable to increase the temperature indefinitely. Because the empty core is the engine, in order to cool the hall fluid, the heating will increase the fuel consumption, and if it is too warm, it will be unrefreshed to drive.

Therefore, it is recommended that the heating be adjusted to a maximum of 25 degrees.
