In addition to the weight of the car, the engine is good or bad, the road conditions, which affect the fuel consumption factor, the various vulnerable and consumable parts on the car will also affect the fuel consumption. For example, if the spark plug is not changed in time, half a box of oil can be stolen every month.
The car three-package standard specifically lists the range of consumables, three filters, spark plugs, tires, bulbs, oil, brake pads, a total of 16 kinds.
To put it simply, the wearing parts are replaced by at least one or two times during the use of the car, and the warranty period is relatively short. Such accessories will actually affect the fuel consumption. How much influence can it affect?
How much oil can affect the fuel consumption?
The oil quality is not changed in time, and the fuel consumption increases by about 2%.
One by one, if the oil deterioration does not change in time, the fuel consumption will increase by about 2%. If the maintenance mileage is used, the earliest changeable wearer is the oil.
The domestic mineral oil is generally changed by 5,000 kilometers, and the total synthesis is 10,000.
Exceeding the service life, the engine oil has the risk of deterioration. After the deterioration, the lubricating oil performance of the engine will decrease, which will cause the friction coefficient of the engine to become higher, the motion resistance to become larger, and the fuel consumption to become higher.
This is like washing your hands, your hands are dry and rubbing with hand sanitizer, the strength is not the same, right?
The oil is too long to serve, and the iron content will exceed the standard.
And the mechanical friction of the engine, it will lead to metal elements become the pollutants of the oil. In general, the iron content in the long-term service oil, the iron content will greatly exceed the standard.
Wuhan University of Technology has experimented with the impact of engine oil on fuel economy. If the iron content in the oil increases by 40 parts per million, the fuel consumption will increase by 2%.
In fact, our national standard oil standard, when the normal oil is dead, the iron content can reach 70 parts per million.
Do not change the oil, spend 30 yuan more per month
Correspondingly, the Chinese Academy of Environmental Sciences also has a data, check it out and look at it.
On average, Chinese private cars consume about 96.82 liters of gasoline a month. According to the calculation of 7 pieces of 4 hairs of 92 tons per liter, the fuel cost is 716 pieces a month.
If the oil does not change in time after the deterioration, it will drag on for a month or two, even if the iron content is only 40 parts per million, it will increase the fuel consumption by 2%, and you will have to pay 20 to 30 yuan more per month.
Every change is dragged for two months, dragging twice a year. Although the surface saves a change of oil, but the light gasoline has not been 120 yuan.
How much influence can air filter have on fuel consumption?
If the environment is poor, the air filter should be changed in advance.
Then talk about air filtration, the car has reached 10,000 kilometers, after changing the oil for 1 or 2 times, the air filter is basically changed. If the environment is relatively poor, the air filter should be changed in advance.
Dust, pm2.5, on the air filter, "Bumper" is in the past. When the filter is too long to block, the engine intake resistance will become larger, and the fuel consumption of the vehicle will increase significantly. .
Air filter blocked, fuel consumption increased by 10%
This is similar to the mask. You can walk when you walk. When you are running, you can't breathe. You have to exhale with your mouth.
But this time you are stuffing a mask, the gas can't breathe, and running there, it is very stuffy, it is very difficult.
The US Department of Energy has another saying, saying that replacing the dirty air filter can reduce the fuel consumption of gasoline by 10%. In turn, we can think about it, dirty it, there is no more than 10%.
Do not change the air filter, spend 70 yuan more oil per month
Then come to settle the account, originally a month of fuel costs more than 700 a little, air filter did not change in time, pay more than 70 dollars a month of oil. A treasure to buy an air filter, about 30 dollars.
That is to say, I did not change the air filter in time, and spent more than one month, wasting money, and getting a deal before and after. Buying 2 or 3 new ones is OK.
What is the impact of spark plugs on fuel consumption?
Spark plug directly affects gasoline combustion
Let's talk about the spark plug. When the mileage of the car reaches 20,000 to 30,000 kilometers, Layette, Jetta, which uses a nickel alloy spark plug, should consider changing the spark plug.
The spark plug is mainly used to generate electric sparks and ignite the mixed gas. That is to say, the spark plug directly affects the combustion.
Carbon deposition affects ignition time and strength
According to the American Automobile Association AAA, for every bad spark plug, the fuel consumption of gasoline will increase by 10% to 15%. And even if the spark plug is not broken, it will take a long time, it will increase fuel consumption.
After a long spark plug, there will be a layer of oxide around the electrode, which is the carbon deposit in our native language. When the carbon deposit reaches a certain level, it will affect the ignition time and ignition intensity.
The spark plug has a serious carbon deposit and the fuel consumption is increased by 30%.
Just like when this lighter is out of breath, you can make it hard to get the switch to the minimum, and the cigarettes can't be clicked.
However, the gas inside the lighter will still be "呲-呲-" flowing out here, the same reason.
Then the AAA American Automobile Association theory, with a set of spark plugs with serious carbon deposits, can increase fuel consumption by more than 30%.
Do not change the spark plug, spend 210 yuan more oil per month
That is the account, 700 yuan a month of fuel, 30% of fuel consumption is more than 210 yuan of oil. If the spark plug is not changed in time, half a month of oil will be stolen by the spark plug, inexplicable.
But for a set of spark plugs, cheap, reliable, more than 100 dollars can be.
How much impact does the battery have on fuel consumption?
Battery life is about 2~4 years
Let's talk about the battery. We have a family car for 2 to 4 years. After almost 3 to 60,000 kilometers, the battery has basically reached the end of its life.
If the car has a modified high-powered speaker, or travels frequently, the car will be parked for a long time, and the life may be shorter.
Decreased battery performance can affect fuel consumption
Then the battery performance is wrong, or the life is reduced, it will also affect the fuel consumption. When the car starts, the fuel injectors, spark plugs and other parts are powered by the battery.
