The cultivation of qualified female drivers 9: I went to refuel for the first time and learned the knowledge of daily engine maintenance.

You may not believe it, but you have been practicing driving for almost half a year. In fact, you have never refueled your car yourself. I can't help it I always have gas when driving!

One weekend, we took our children to the playground to play. As usual, I rushed to the public office when I went, and let me drive when I came back.

On the way back, halfway through, I saw that there was only one fuel gauge left, so I asked my husband, "Does the car need gas?" ?

Impossible, I can't help asking him about the car. In fact, there is no need to ask such obvious questions!

As a result, my husband's answer was just as I expected. He said, "If there is no oil, you have to add it!" You're a driver. Do you have to ask? "

Not far away, we arrived at a gas station that often refueled. My son likes to go to this gas station best, because the service of this gas station is very good, and it will provide drinks for customers who come to refuel, such as sour plum juice or orange juice. Every time I pass by, my son wants a drink.

Although I have never refueled, I have witnessed the process of refueling countless times. I drove the car carefully to the refueling position for fear of driving in the wrong direction. The refueling staff enthusiastically helped me guide in place, stopped the engine and opened the window. The staff took the oil gun and waited for me to open the gas cap.

At this point, the embarrassing thing appeared! After groping for a long time, I couldn't find where I could open the fuel tank cover. At this point, the husband who was sitting tight couldn't sit still, so he quickly got off the bus and pointed to the switch of the gas cover for me.

Next, you should pay when you are full of oil. The staff said to pay directly in it. I'm still a little confused. Don't you need to give me a ticket or something? My husband saw my doubts, and he said, "You go in and tell him the location directly, what the money is, and come out after paying the money ticket."

I walked to the cashier with a grain of salt and paid with Alipay in the way he said. After I got the receipt, I checked the information and gave it to the staff who refueled.

Only then did we find that our car had been parked in front of the gas station by my husband, for fear of affecting the cars behind.

Finally completed the process of refueling the car. I think you might say, is this exciting, too? But what I want to say is that it is simple for an old driver, and it is also the first time that a novice driver can be proud of it!

Back in the car, my husband quipped, it feels good to refuel for the first time! Give the car maintenance next time, and let you go to the scene to experience changing the oil for the car!

I said, "Didn't the employees of the garage do the oil change?" Do you have to change it yourself "

He said: "It is good to let others change it, but you should know when to change it, when not to change it, and what kind of oil is suitable. You know, oil is the focus of engine maintenance. "

Just then, we saw an old Volkswagen in front of us, spraying a blue tail gas when filling the door. I asked curiously, "Is this Volkswagen broken?" . Husband calmly said, "Burn the engine oil."

This word seems to be heard often, although I don't quite understand what "burning engine oil" is. Just mumbling: "burning oil?"

Husband simply explained: "It may be that there is a problem with the spark plug or the valve oil seal, which causes the oil to jump into the engine combustion chamber, or the oil leaking from the valve guide participates in the combustion. This is engine oil, and the exhaust gas discharged when the engine oil burns is blue. "

Seeing that I didn't talk, my husband went on to say, "Have you ever seen a car emit black smoke? That is, the exhaust gas is black. By the way, do you have a white one? These are abnormal exhaust colors. "

I tried to recall that I seem to have seen someone smoke black, but I don't remember anyone smoking white. But now, I am quite curious and ask, "What is the reason?"

"The tail gas is black because the fuel is not completely burned. White exhaust gas is mostly caused by spark plug failure and poor fuel quality, fuel does not meet combustion standards, or gasoline contains moisture, so white exhaust gas will be discharged. "

Look at my worship. How could he miss such an opportunity to show himself? Then he taught me a lesson: "When driving, be sure to pay more attention to the engine. If there is any abnormality, stop and check in time. If the engine fails, the vehicle will be overhauled, which will have a great impact on the valuation of the vehicle. "

"Well, when I come back, I will check the precautions for using the engine online to ensure that our small fit is healthy." I answered half jokingly and half seriously.

Unconsciously, I have arrived at the community. As usual, I arrived at the door. The husband took his son out of the car and went home. I'll park in the parking lot.

I suddenly found that every time I drive, I always learn some new knowledge. I didn't expect to know so much about driving. It seems that it is not so easy to become a qualified driver.

Fortunately, in this era of information flooding, as long as you are willing to learn, there are always channels and methods. That night, I looked up the precautions about the use of the engine on the Internet.

As the core component of the car, the daily maintenance of the engine is definitely worth taking the time to understand. If your ordinary car can do the following, there will be no overhaul if it is more than100000 km.

First, engine oil is the center of gravity of the engine, and special attention must be paid to the use of engine oil:

1. The engine oil with proper quality grade must be used, which is the key to ensure the normal operation of the engine.

2. Change the oil regularly or according to the quality. Any quality engine oil will change some physical and chemical indexes after a certain mileage, which will bring harm to the engine and cause failure, so it is necessary to change the engine oil regularly according to the change of engine oil quality. If you can't judge the time, just remember that if you use it in the whole city, synthetic engine oil can't exceed 10000 km, ordinary engine oil can't exceed 6000 km, and you can get a 20% discount on bad road conditions!

3. Temporary use of alternative oil products shall be observed.

If the oil supply is not timely or there is no suitable engine oil, you can temporarily use alternative engine oil, but you must strengthen observation during use, pay attention to the quality of engine oil and whether the engine oil filter is blocked, and stop in time when problems are found.

4. Choose the oil with proper viscosity.

It is wrong to choose the oil with proper viscosity according to the local temperature. It is wrong to think that the greater the viscosity, the better, because the viscosity is too high and the oil flow is too slow at first, which will easily aggravate the wear of parts and even cause tile burning accidents.

5. When changing oil, clean the waste oil.

In order to prolong the service life of the engine, the old engine oil should be drained when changing the engine oil, so as to avoid polluting the newly added engine oil, making the new engine oil deteriorate rapidly and causing corrosion and wear of the engine.

6. Keep the crankcase well ventilated.

The gas entering the crankcase from the combustion chamber is corrosive, which can make the engine oil oxidized and deteriorate and pollute the engine, so it is necessary to keep the crankcase well ventilated.

7. Maintain normal oil level.

When the amount of oil is insufficient, it will not only accelerate the deterioration of engine oil, but also cause the burning of parts due to lack of oil; On the contrary, if there is too much oil, the oil will run into the combustion chamber along the gap between the cylinder wall and the piston ring, causing the engine to burn oil. In addition, the oil level is too high, which increases the stirring resistance of engine oil, increases oil consumption and aggravates wear.

Second, pay attention to the maintenance of the fuel system, and use good quality fuel when changing fuel.

1. Select good quality fuel according to engine standards, and add fuel additives when necessary to keep the engine running well.

2. Replenish fuel in time

3. Clean the fuel system regularly.

In the process of supplying automobile fuel to the combustion chamber through the oil circuit, a little gum and carbon deposit will be formed more or less, which will cause problems such as poor engine acceleration. So we need to clean the fuel system regularly,

Third, maintain the air intake system regularly.

The air intake system of an automobile is very important, because the air quality will affect the normal operation of the engine, so the air intake system of an automobile should be maintained regularly. First of all, we should check and replace the air filter regularly, because the air filter can prevent dust and other particles from entering the engine and provide clean air for the engine. Then we need to clean the intake pipe of the car regularly. If the intake pipe of the engine is dirty, it will aggravate the wear and aging of the engine. So if the car passes through a dusty place, be sure to clean the intake pipe. There are also many dusty weather in spring, so the intake pipe should be cleaned frequently.

Fourth, pay attention to the maintenance of radiator.

Sometimes some big problems of the engine are caused by poor heat dissipation and high local temperature. Traditional engines have heat dissipation problems, which are often caused by radiator blockage.

Because radiators need a lot of air to dissipate heat, they are all designed in the front, but the cooling holes are relatively narrow, and the dust catkins are not easy to fall down after entering. Of course, there will be problems if you don't clean it for a long time.

Five, regularly check and clean the water tank.

The water tank of the engine is a very important part of the engine because it can help the engine to dissipate heat. The engine water tank often rusts and scales, which reduces heat dissipation and makes the engine heat, so we should clean the rust and dirt of the engine water tank regularly and keep it clean. In addition, the coolant in the automobile water tank should be replaced regularly, because the impurities in the coolant will affect the heat dissipation effect for a long time, and it should be replaced after driving for 30 thousand kilometers or one year.

Sixth, always pay attention to the dynamics of the dashboard

Now the dashboard of the car is very comprehensive and the information function is quite rich. And often when the engine has any abnormal signs, it will give a reminder. I just don't pay attention sometimes.

Seven, regularly check the important parts of the engine.

Check and adjust the valve clearance, valve timing and injection pressure of the engine regularly to ensure that the engine is in good condition. In addition, the engine belt should be inspected regularly. If cracks appear, they must be replaced in time.

In addition to the above maintenance methods, everyone should also clean the outside of the engine regularly, so as to extend the life of the engine.

Eight, the following is the engine-related common fault analysis.

1, the automobile exhaust noise increases, and the exhaust emission increases beyond the standard.

This reason may be due to the oxidation of engine exhaust gas at high temperature, which leads to the leakage of exhaust system.

Maintenance method: the owner must regularly check whether the pipes and interfaces (especially silencers) of the exhaust system are corroded or damaged by exhaust gas! If you find a problem, you must go to a professional repair shop for repair.

2. Does the performance of automobile engine decrease obviously with the increase of fuel consumption?

This is probably due to the lack of replacement of engine oil, oil filter, air filter and gasoline filter for a long time, resulting in insufficient fuel combustion and increased carbon deposition in the engine.

Maintenance method: The above maintenance items should be replaced regularly according to the maintenance manual. If the vehicle is often used in harsh environment, it is recommended that the owner change the oil and oil filter every 5,000 km, and the air filter and gasoline filter every 1000 km, otherwise, the oil circuit and air passage will be blocked and the normal operation of the engine will be affected.

When the car starts, the engine will not catch fire.

There are two main reasons for ignition failure, and the most likely reason is that the battery is rusty or leaking. Secondly, the spark plug of the engine is wet in rainy days.

Maintenance method: It is best to check whether the battery liquid is sufficient every one or two months (the liquid level is considered appropriate between the upper and lower scribed lines), and also check the liquid level difference of each tank. If the liquid level is insufficient, you need to unscrew the cover on the battery and pour distilled water to make up the liquid level. After that, it is necessary to keep the battery terminals clean. If the spark plug is wet, take it out and try to let the water evaporate as soon as possible.

4. Has the fuel consumption of cars increased inexplicably?

In fact, there are many reasons for the increase in fuel consumption. But the most common is the increase in fuel consumption caused by insufficient tire pressure.

Maintenance method: Pay more attention to observe whether the tires of your car are angry when driving, and check the tire pressure regularly. When the temperature is high in summer, the tire pressure will be higher than usual, and it is more accurate to measure the tire pressure in cold weather or in the shade. If it is necessary to replace severely worn tires, it is best to replace two or four tires together, and tires with the same grain can be replaced alternately.

5. The car oil pump is damaged

Some car owners always wait until the fuel alarm light is on before refueling, which will shorten the service life of the oil pump and even burn it out. If the owner often drives in the urban area and it is convenient to refuel, there is no need to fill it up, because filling it up will lead to oil floating, sensor failure, oil gauge distortion and increase fuel consumption, so it is recommended to refuel when the fuel consumption is similar.
