The more the car is driven, the more fuel it consumes
The more the car is driven, the more fuel it consumes. With the improvement of people’s living standards, most families now have cars. After buying a car, you need to pay attention to the car. The maintenance of the car also requires a lot of energy, but after long-term use, the car will inevitably have various problems. Let's find out why the car consumes more fuel the more you drive it? The more the car is driven, the more fuel it consumes 1
The reasons why the car consumes more fuel:
1. The engine has carbon deposits. Stop-and-go traffic in the city will increase carbon deposits, and the habit of idling and warming up the car will also increase carbon deposits. Many road conditions and driving habits will also increase carbon deposits. If there is too much carbon deposit, it will affect the air intake of the throttle and the car will easily stall. The carbon deposit will also adhere to the air intake duct, reducing the air intake efficiency and worsening the mixture of oil and air. Severe carbon deposit will also Occupying cylinder volume also affects combustion quality and causes knocking.
2. The spark plug needs to be replaced. The spark plug is responsible for igniting the mixture in the cylinder. Year-round operation consumes it, resulting in insufficient ignition energy and insufficient sparkle. The combustion time of the cylinder is very short, and there is no time to start slowly. The quality of the spark at the moment of ignition is directly related to the quality of combustion and the completion of combustion.
3. The oxygen sensor is broken. If the car reaches operating conditions of 120,000 to 150,000 kilometers, you can consider replacing it. The oxygen sensor is installed in the vehicle exhaust pipe and is responsible for detecting the oxygen content in the exhaust gas and providing feedback to the engine's electronic injection control system.
4. The "three filters" were not replaced in time. If the "three filters" are not replaced for a long time, there will be more dirt inside them, which will affect the use. There will be large errors in the data transmitted to the engine ECU, resulting in increased fuel consumption.
What causes a car’s high fuel consumption?
1. Tire pressure
If the tire pressure is too low, the stress area of ??the tire increases, and the resistance during driving becomes higher, which is the main reason for higher fuel consumption. Car owners must pay attention to the maintenance of their tires on a daily basis, check the tire pressure regularly, and inflate the tires in a timely manner.
2. Carbon deposits
Car carbon deposits are directly proportional to fuel consumption. The intake pipes become smaller and rougher due to the accumulation of carbon deposits, causing gasoline to pass through. When the resistance increases, the combustion quality will be affected, and the fuel consumption will naturally increase. Therefore, the car engine should be cleaned regularly to reduce carbon deposits.
3. Air conditioning
Generally, fuel consumption is higher in summer. Because of the hot weather, many car owners quickly turn on the air conditioner every time they get in the car. This not only results in poor cooling but also increases Due to the pressure of the engine running, it is best to turn on the air conditioner after the vehicle has been started for a period of time. This will allow the engine to fully operate and the effect will be good. You should also pay more attention to the cleaning of the air conditioner.
IV. Air filter element
The function of the air filter element is to filter some impurities, dust, etc. in the air, which helps the gasoline burn more fully. After using it for a long time, there are too many impurities attached to the air filter element, which can easily block the filter element. At this time, the incoming air becomes smaller, the car's power will be obviously insufficient, and the fuel consumption will increase accordingly, so it must be replaced or cleaned regularly. Air filter.
During daily maintenance and repair of the vehicle, inform yourself that the fuel consumption of the vehicle has increased, and ask the maintenance personnel to help check the basic conditions of the tire pressure, air conditioner, spark plugs and other parts of the vehicle. If there are any problems, be sure to replace them in time, which can be effective Reduce vehicle fuel consumption. The more the car is driven, the more fuel it consumes 2
If you find that the fuel consumption of your vehicle has increased significantly, you need to check the following aspects.
1. Check the tire pressure and four-wheel alignment
If the tire pressure does not reach the normal value, the contact area between the tire and the ground will increase, and the friction will also increase. Large, so when the vehicle is traveling at the same speed, when the tire pressure is insufficient, the vehicle will provide more power, so the fuel consumption will be greater.
The purpose of regular four-wheel alignment is to keep the toe angle and inclination angle of the wheels in a normal position. Especially after replacing chassis accessories, shock absorbers and other accessories, the vehicle needs to do a four-wheel alignment. position. The toe angle of the wheel can be understood as solving the problem of the tire running in an "inside-out" or "outside-in" shape, while the inclination of the wheel can be understood as the inclination angle of the wheel.
After adjusting these data to appropriate values, the vehicle can reduce resistance when driving, maintain a straight line and reduce tire wear.
2. Check the oxygen sensor
The main function of the oxygen sensor is to detect the oxygen component contained in the exhaust gas emitted by the vehicle, and then send the information back to the driving computer, so that the driving computer Timely adjust the fuel supply for engine combustion. If the oxygen sensor detects too much oxygen in the exhaust, it means there is too much air intake and not enough fuel injection. Therefore, the oxygen cannot be used up, and multi-fuel injection will be adjusted. If the oxygen content is too low, it means too much fuel injection and insufficient air intake, so less fuel injection will be adjusted.
When the oxygen sensor fails, it will transmit an incorrect signal to the trip computer, allowing the trip computer to determine that more fuel needs to be sprayed, which will cause the vehicle to malfunction. Fuel consumption increases. More fuel is injected, but the combustion in the engine is actually not sufficient, which will produce more carbon deposits inside the vehicle's engine, leading to reduced vehicle power, unstable idling, clogging of the three-way catalytic converter, burning of engine oil, etc. A series of questions.
3. Check carbon deposits and three-way catalysis
Every car engine will have carbon deposits to some extent. Although a small amount of carbon deposits will basically not cause damage to the vehicle engine, But if there is a lot of carbon deposits, it will have some impact on engine performance. In cities, road congestion is the norm, and when vehicles are idling or stopping and running, due to insufficient combustion, it is easy to cause more carbon deposits in the engine over time. Moreover, the formation of carbon deposits is directly related to gasoline quality, engine oil quality, driving habits, etc.
The function of the three-way catalytic converter is to filter the exhaust gas emitted after combustion of the car, and convert the toxic and harmful substances CO, HC, NO x, etc. into harmless carbon dioxide through oxidation and reduction reactions. , water and nitrogen functions. The interior of the three-way catalytic converter is composed of porous ceramic materials or metals. The three-way catalytic converter is covered with a layer of precious metals such as platinum, rhodium, and palladium and a rare earth coating.
When the carbon deposits fall from the vehicle's engine and are discharged, it will easily block these small holes, causing the vehicle's exhaust to be blocked, causing the vehicle to increase fuel consumption and reduce power. Therefore, it is also very important to regularly check the carbon deposits inside the vehicle engine, clean the carbon deposits regularly, and maintain good driving habits. The more the car is driven, the more fuel it consumes 3
Several reasons why the car consumes fuel
Cars idling for a long time
Generally, long-term idling occurs because of waiting Staying in the car for a long time while in person, and turning on the air conditioner, stereo, etc.
When idling in place for a long time, it seems that the engine speed is not high, and it feels like it is not consuming fuel. However, because the vehicle is not moving in place, the vehicle computer will increase the average fuel consumption when calculating statistics. a lot of.
In addition, if you idle for a long time, the fuel in the engine will not be fully burned, so carbon deposits will be produced. If this is often the case, the carbon deposits in the engine will increase significantly.
One foot on the accelerator and one foot on the brake
Smooth and gentle driving is the most fuel-efficient way. Everyone knows this. However, because there are many vehicles on the road, some people often press the accelerator when driving. After catching up with the car in front, they apply the brakes to slow down. The oil that has just been fed into the engine has not been completely burned and is about to use power.
It was killed by your brakes, so it consumes a lot of fuel. It doesn’t seem like driving vigorously, but the fuel consumption is not low, so control the accelerator when following the car and don’t give it too much. Large, so you can avoid braking as much as possible and save fuel unconsciously.
Frequently slowing or speeding
For general household vehicles, the economic speed of the vehicle power system is around 80 kilometers per hour, and the maximum speed is at 80 kilometers per hour. In the fuel-saving state, driving too fast or too slow actually consumes more fuel.
Install roof frames or brackets
Many friends who like to travel by car or outdoors will install various brackets or roof frames on the roof to carry more things. , but this behavior actually destroys the wind resistance coefficient of the original car. When driving at high speed, the additional fuel consumption caused by wind resistance may exceed about 5% of the original car's fuel consumption.
Opening windows at high speed
Many people think that opening windows at high speed will save fuel than turning on the air conditioner, but this is not the case. When the vehicle speed exceeds a certain range, the resistance brought by the air is a factor that cannot be ignored. When the vehicle is designed, the entire vehicle has been tested for the drag coefficient. However, opening the windows will completely destroy the vehicle's wind resistance balance, and sudden high-speed When the windows are opened, the vehicle may vibrate violently. You can imagine how much extra fuel consumption it will cause, which is definitely more than the air conditioner.
Failure to maintain vehicles according to regulations
Many car owners have experienced over-mileage maintenance, and they all think it doesn’t matter, as long as they can save money. In fact, this kind of over-mileage maintenance will not only have an impact on the engine, but will also directly lead to an increase in fuel consumption.
It is normal for a poorly maintained engine to have a 10% or 20% increase in fuel consumption. A dirty air filter may also cause a 10% increase in fuel consumption. In order to maintain the best performance of your car, it is best to change the oil as specified and check the filter, which is also very important for car maintenance.
Insufficient tire pressure
When the tire pressure is insufficient, the resistance will increase when the tire rolls, which means that the engine must output more power to meet the vehicle's driving speed. The more power the engine outputs, the more fuel it consumes.
According to tests, under normal circumstances, insufficient tire pressure will increase fuel consumption by 5%-10%, and there is also the risk of tire blowout!
Too many things in the trunk
Cleaning out unnecessary things in the trunk can reduce the weight of the car and save energy. The relationship between vehicle weight and fuel consumption is directly proportional. It is said that for every 10% decrease in vehicle weight, fuel consumption will also decrease by several percentage points.
There are many factors that affect fuel consumption, and saving fuel also requires experience.
I believe that car enthusiasts can learn more and accumulate experience. As long as they pay more attention to the above points, it is not difficult to save fuel!
