As domestic new energy vehicles continue to impact the domestic automobile market, many car factories are forced to end up in a price war with new power car manufacturers, and even luxury cars of first-line brands are inevitable.
Although the overall price of cars has fallen, especially for many people to realize their dream of luxury cars, but over time, these car owners have found that something is wrong.
Although the price of buying a car has been reduced, the cost of refueling and maintenance has not been reduced at all, especially in terms of maintenance, and some parts cannot be repaired to "stop".
This seems to confirm the old saying in the industry, "Cars are not broken to drive, but repaired". Is this statement true at all? So what are the auto parts that are most afraid of repairing?
1. How are auto parts "broken".
On this topic, everyone must have their own experience, after all, in addition to cars, there will be other mechanical equipment used in daily life, and there will always be large and small problems.
In fact, if you want to talk about how bad the parts of the car are, in addition to the human factor and car accidents, it is actually two very simple points, one is not to use the car for a long time, and the other is to use the car too much.
1. Leave the car for a long time
After buying a car, many people find that commuting to work is not too convenient, but it is not as fast as riding electric cars and bicycles, so the car has been put on hold at home.
However, when the owner is in an emergency, he wants to drive and travel, but finds that there will be some small problems in the car starting process, and there will even be some spare parts failure.
This is because machinery and equipment also need to be run-in, and this is especially true for automobiles. If you don't start your car for a long time, the machinery in the car will not be running.
For example, if the engine has not been "drunk" for a long time, there will be no gasoline passing through its internal pipes. If the pipe is idle, there is a risk of rust. So even if you haven't driven a car, there will be damage to the car parts.
In addition, leaving your car on hold for a long time may cause the oil stored inside to deteriorate. When driving again, the spoiled engine oil will continue to destroy your car parts, resulting in damage to the car parts.
2. The car is driving too much
Machinery, like people, cannot be in a state of rest all the time, and at the same time, they cannot be overworked.
Some people may have to drive far away every day due to their daily work and life needs, which leads to the owner may have to run more than 50,000 kilometers every year, which will naturally affect auto parts.
In addition, some car owners have no time to carry out car maintenance, and they don't take it seriously if there is a small fault, so they find a small repair shop everywhere to repair and replace the parts of the car.
The parts provided by these small repair shops are not the original parts of the car, and they do not match the car, just like the "rejection reaction" produced by human organ transplantation, and the car has been suffering from parts from other factories.
Of course, in addition to these, it is also related to the driving habits of the owner, the road section that is often taken and the gasoline that is usually added, which will affect the use of auto parts.
For example, some cars need to add high-quality gasoline, but 92 per day is fine. Although there is no problem with normal operation, it will inevitably affect the normal operation of the engine after a long time.
Second, the car should not be repaired diligently
1. Throttle
When it comes to the name throttle, many people will be unfamiliar with it and don't know what its function is.
In fact, the throttle valve is the switch between the engine and the outside air, which can control the gas to enter the engine block.
As for the opening and closing function of the throttle, it is to make the gas in the air and the gasoline entering the engine become a "combination", so that the combustion process of the engine is more sufficient, and at the same time, the efficiency of the engine can be higher.
Since the throttle can "release" gas into the engine, all kinds of fine dust and debris in the air must be used as the last line of defense, so this is why the throttle will become very dirty.
Seeing this, many people will think that the throttle is so important that it needs to be cleaned frequently, and the effect will be better, but in fact, this is not necessary.
Although after the throttle is cleaned, it will make the car easier to drive, which is the consensus reached by most car owners.
Frequent disassembly will inevitably lead to the throttle installation part often in a state of friction, which will eventually cause a certain gap around the throttle, so that gas can enter the engine through this gap, and the gains outweigh the losses.
Therefore, the cleaning of the throttle, it is best to judge according to your own car condition, if you find that the engine is running a little "hard", it is not too late to take out the throttle for cleaning.
2. Carburetor fuel filter
That is, the so-called external gasoline filter, which is similar in function to the throttle mentioned above, is a door that the engine must pass through to "contact" with the outside world. However, a carburetor fuel filter is used to filter the gasoline entering the engine, so that the gasoline that can be used by the engine is free of impurities that affect the operation of the engine.
Therefore, the work of the fuel filter can be said to be a very important part, after all, it is the most important engine in the car that is served.
If the filter fails, there is a possibility that the gasoline will go directly into the engine without filtering, or that the gasoline will be blocked directly.
But unlike throttle valves, fuel filters are mostly disposable filters, and if something goes wrong, the best thing to do is to remove them and replace them.
The filter is also not recommended to be replaced and repaired frequently, the reason is roughly the same as the throttle, and the filter also has the possibility of installing "anti", if you replace it yourself, once the installation is reversed, the damage to the car can be said to be very large.
3. EFI fuel filter
This is the same function as the carburetor fuel filter, but it is used in different vehicles depending on the body engine.
The EFI fuel filter is also used to filter gasoline, and it is located at the outlet position of the fuel transfer pump, which is the opposite of the position of the carburetor type, so it is called a built-in gasoline filter.
Compared with carburetor fuel filters, it will have higher requirements for gasoline quality, which means that poor gasoline quality will cause more damage to the gasoline filter.
Therefore, it is generally recommended that you add high-quality oil to reduce the damage of the filter element, so as to reduce the replacement and maintenance of these accessories.
4. Oil filter
As one of the "three filters" in automobiles, the oil filter can be said to have the same troubles as the three "brothers" mentioned above.
The oil filter is a device that provides lubricating oil for the entire mechanical equipment of the car, and its mission is to remove all kinds of impurities from the oil, so as to send clean oil to all parts of the car.
Because this part of the work is very important, the oil filter is also an accessory that is not recommended for regular maintenance. In order to make the oil filter more "healthy", it is recommended that when adding engine oil, it is best to choose an oil with fewer impurities.
5. Antifreeze
Antifreeze is a type of antifreeze coolant that needs to be used in cars all year round, which can be antifreeze in winter and boiling in summer, so its importance should not be underestimated.
However, the process of replacing the antifreeze is very cumbersome, you need to rinse off the previously failed antifreeze with clean water, then make sure that there is no water in the pipe, and finally add new antifreeze to the pipe.
Such a cumbersome process, if there is a slight mistake in the middle, can lead to some problems in the antifreeze system.
If you don't need to travel long distances because of the demands of your job, it's best to replace your family car every two or three years.
3. What do you need to pay attention to in daily car repair and maintenance?
If it is a family car for maintenance, the "three filters" mentioned above plus antifreeze can be replaced after more than one to two years.
The parts that need to be checked and even repaired for each maintenance are brake pads and paint, the paint is to make your car look more beautiful, and the brake pads are related to their own safe driving.
But if it is said that there is a lot of dust in the place where you usually drive, the five parts mentioned above that cannot be replaced and repaired often can no longer be treated like ordinary family cars.
In order to maintain the life of the car and the quality of the engine, the four filters need to be replaced or cleaned frequently.
This cleaning cycle can be carried out once when the car has traveled about 20,000 kilometers, and if the owner is still a little worried about affecting the engine, this distance can be changed to 7,500 kilometers.
Fourth, it is a good habit to prevent damage to auto parts
In fact, whether it is maintenance or car maintenance, it is a large expense, so if you can avoid damage to car parts, you can make car owners more worry-free.
On weekdays, it is best to fill up with high-quality gasoline and engine oil.
Although the unit price may be higher, the utilization rate of high-quality gasoline and motor oil will be much higher than that of low-quality gasoline, and the total consumption will be about the same.
High-quality gasoline will also contain fewer impurities, and the filter will not be as heavy to work on, so that it will not cause damage to the car engine.
And in the process of daily driving, try to avoid driving on some roads where the road section is not very good, especially the construction site and dirt road.
If you drive on a daily basis and drive on an ordinary road, you can reduce the accumulation of particulate matter in the three filters, thereby reducing the number of times you need to wash them.
summary
In the final analysis, cars and people are still relatively similar, there will always be some problems big and small, but some problems are not in the way as the doctor said.
We also know that some car owners are also passionate about cars, and they can't wait to "cure" the problems of their cars.
But often things don't go as they want, and there are more and more problems with the car repair.
Therefore, after you find that there is something wrong with the vehicle on weekdays, it is best to understand the situation first, see what the best way to deal with it is, and don't fall into a misunderstanding!
