The owner's family car knowledgeCars are becoming more and more popular, and there are more and more cars running on the road. It's really convenient to drive a car when traveling, but like a person, a car needs rest and maintenance if there is a lot of work. The following is the experience of an automobile media editor when he visited major automobile franchise stores and responded to customers.

The so-called car maintenance refers to the process of using special care materials and products of different natures to carry out a new maintenance and care of the car according to the maintenance conditions required for different materials in each part of the vehicle. Modern car maintenance mainly includes the maintenance scope of the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

Usually need to pay attention to:

When driving, it is necessary to cultivate every morning before driving: check the oil dipstick, fill in the lack of oil, and replenish it in time. Check whether the water in the water tank is missing, and check the brake fluid, so there is usually no problem. Usually there is not much attention to car maintenance. Just pay attention when driving. Before driving every morning: check the oil dipstick, fill in the lack of oil, and replenish it in time. Check whether the water in the water tank is missing, and check the brake fluid, so there is usually no problem.

Also pay attention to the following points when driving:

1: Do not use idle speed to warm up the engine. The current electronic fuel injection engine has a temperature compensation control system, which can meet the normal driving of the vehicle in a cold state. If the EFI engine is warmed up for a long time, it will only increase fuel consumption invisibly. After the car is started, the temperature should be raised on the spot, and the water temperature should reach the starting temperature before starting. When driving, choose a good road, keep driving at a medium speed, keep the accelerator low, and try to avoid sudden acceleration and sudden braking.

2: Do not drive the engine at high speed while driving.

3: To avoid overloading the engine. Full load operation is easy to cause damage to the machine parts, so it cannot exceed 75%-80% of the rated load. These aspects are issues that need to be paid attention to for novices. Never help others to tow trucks. Towing trucks can be harmful but not profitable.

4: Always check whether the oil, coolant, battery, and electrolyte are sufficient, and if there is a lack, it must be refilled in time.

In-car maintenance:

Car body maintenance is to keep the car young, and the purpose of car maintenance is to allow the car to travel hundreds of thousands of kilometers without major repairs, and to ensure that the car is in the best technical condition. It mainly includes: lubrication system, fuel system, cooling system, brake system, carburetor (fuel injector) maintenance, etc. People usually pay attention to the appearance of the car intuitively, but whether the car is refreshing or not is often ignored. In fact, whether the car is comfortable or not is what the car owner enjoys and should not be ignored.

1. Clean the seat:

In order to keep the seat clean, the simplest and most effective method is to prepare two sets of cloth seat covers, which can be replaced and cleaned at any time.

Dirt on the seat makes people uncomfortable. Generally, when it is not very dirty, it is recommended to use a long-haired brush and a vacuum cleaner with strong suction. While brushing the surface of the seat, use the suction port of the vacuum cleaner to suck out the dirt. The effect is quite good. This method has a good cleaning effect for seats of different materials.

For particularly dirty seats, several steps must be taken to clean them thoroughly. First of all, use a brush to clean the dirty parts, and then use a clean cloth with a small amount of neutral detergent. In the case of semi-dry and semi-wet, wipe the surface of the seat completely. Special attention is that the cloth must be twisted. Dry to prevent excess moisture from infiltrating into the sponge, because it is uncomfortable to sit on a wet seat, and it is more likely to be contaminated by dust; finally, clean the seat with a vacuum cleaner to eliminate excess moisture and make the seat dry as soon as possible stand up.

When eating in the car, you must be careful not to let the fine food residue fall on the seat of the car, causing the breeding of mites or other microorganisms to produce strange odors.

2. Cleaning the carpet:

The carpet that comes with the car itself is basically integrated with the car, and it is not easy to remove it for cleaning. It is best to place movable foot pads in the car.

If the foot pads are not too dirty, they can be patted outside the car. If you use a vacuum cleaner with a brush head for vacuuming, you can make the dirty carpet look less dirty.

For more dirty carpets, you can only use special detergents. Generally, the above two dust removal tasks are carried out before detergents are used, and then an appropriate amount of detergent is sprayed, washed with a brush, and finally a clean rag is used to remove the excess. The detergent can be sucked off, so that the washed carpet can be clean and soft as before.

The most important thing to note is that the carpet should not be completely soaked and scrubbed in water. On the one hand, it will damage the bonding of the different layers of the carpet. On the other hand, the carpet will not dry out for a long time, which will affect the use effect and cause the interior of the car. Damp.

3. Maintain the dashboard:

Everyone in the car will directly face the instrument control panel. Its cleanliness is the most important feeling for whether the car is clean or not.

Paying a little attention to the dashboard will find that there are few parts that can be cleaned with only rags and sponges. These ditches and ridges require "special tools". In this case, the "special tools" designed by yourself can come in handy. Various wood chips or rulers of different thicknesses, repairing its head into oblique triangle, rectangular or pointed shapes, and then wrapping it in a clean rag to sweep the ditch and ridges, is the most ideal thing. It has a cleaning effect without causing damage to the cleaned part.

For example: using a relatively wide-mouthed wood chip or ruler, wrapped in a rag to clean the shutters of the air-conditioning air outlet, it is very smooth and not bad; using a sharper wood chip or ruler, wrapped in a rag to clean the corners of the instrument switch, etc. It is easy to clean the dust.

After cleaning all parts of the dust, spray it with special instrument wax, and then wipe it with a clean rag after a few seconds, and the instrument panel will be "rejuvenated".

4. Maintenance of special materials:

In order to make the interior of modern cars more beautiful and comfortable, a large number of complex materials are used, and most of them are vinyl plastic fibers.

For them, spray the cleaner directly on them; then wipe them with a rag; don't forget to spray a layer of vinyl rubber protective agent at the end to prevent premature aging and brittleness and hardening.

For the leather interior parts of high- and mid-range cars, regular cleaning and maintenance should be adhered to, so that they will not dry and age and crack and damage. When cleaning the leather, use a special cleaner to moisten the cloth on the cleaning operation. After completion, it is better to use natural drying. Finally, spray the special leather wax and polish it with a dry cloth. As long as the maintenance is regular and proper, leather jewelry can be used almost permanently.

5. Interior cleaning and maintenance:

When many car owners perform routine maintenance on their cars, the appearance and maintenance of important parts are always very cautious, and occasionally they ignore the cleanliness of the car. How to clean and maintain car interiors is a knowledge that many car owners need to understand.

Car owners need to strictly follow the trilogy of dust removal, cleaning, and maintenance to thoroughly clean and maintain the instrument control panel, roof, rear cylinder platform, seat, floor velvet, and inner door panel. In the cleaning process, all neutral or weak acid cleaners are used, and the residues are free of harmful gases and volatilize automatically within a few seconds, which is safe and environmentally friendly, and will not cause any harm to the human body.

Outside maintenance:

1. Maintenance of lamps and lanterns:

It is an extremely quick and simple task to check the bulbs of lamps outside the car for burnout failures. However, it is not so simple to maintain a comprehensive system of exterior lamps.

Timely maintenance of exterior lights is very important to the driver, because it not only affects the comfort of driving, but also directly affects the safety of driving. It is often difficult for car owners to realize that the headlights, taillights, turn signals or parking lights are not working properly before being reminded. By the way, the job of replacing a burnt out bulb is very simple, and the cost of DIY is lower than the charging standard for maintenance of the lighting system at the repair station.

In more cases, the failure of car lights is by no means limited to small problems such as burned bulbs, rusted sockets, or damaged plugs. It is often necessary to adopt professional diagnostic techniques to analyze the root causes of the failures. Even for those low-priced cars, their internal and external lamps are controlled by the main computer; and for those luxury cars, only the headlights are controlled by three computers.

If the car is equipped with daytime running light DRLs, you must first understand how these devices work. For example, some daytime running lights cannot be turned on before the engine is started; for some daytime running lights, if the parking brake has not been cancelled, even if the engine has been started, the daytime running lights still cannot work normally. If the vehicle is equipped with light-controlled lights, you may wish to check the working conditions of the lights during the light sensitivity from the weakest to the strongest. Of course, do not neglect to check the automatic shut-off timer. If the system is equipped with a timer, set it to the maximum delay.

If the headlights are damaged, they are usually replaced with similar lamps. Some cars are equipped with high-intensity discharge headlights HID, which generates high-density light sources through high-voltage arc discharge generated by its pre-designed electronic system. Note that ordinary quartz-halogen bulbs cannot be used here. In addition, check the headlight lens for cracks, because although surface cracks will not affect the lighting performance of the headlights, moisture will penetrate into the lamps along the cracks, which will inevitably reduce the service life of the bulb.

The calibration of the direction of the headlights should also be included in the list of maintenance items, because in order to ensure the maximum safety of the driver, the headlights must be able to provide good forward lighting for moving vehicles.

2. Maintenance of exterior paint

Car paints are generally baking paints. In the car factory, after the frame and shell are welded (sometimes manually repaired), the next process is painting. Generally speaking, the first is the primer. Dip the bare car shell into a syrup-like paint tank, take out the drying primer; then send it to a dust-free workshop to spray the top paint with electrostatic spray paint. Then use a temperature of about 200 degrees to dry. For the more refined ones, another coat of varnish will be applied. In this way, the paint process is complete. There are several general topcoats: ordinary paint; metallic paint; pearl paint. Needless to say, ordinary paints, resins, pigments and additives. The metal paint has more aluminum powder; so it looks bright after finishing. For pearl paint, mica particles are added. Mica is a thin piece of material, therefore, the reflection is directional and has a colorful effect. If it is metallic paint plus a varnish layer, the paint on the car looks very bright and beautiful. In terms of color, white is undoubtedly the cheapest. For example, the world-class brand red pigment is about 25 times more expensive than the world-class brand titanium dioxide; while the amount of titanium dioxide used in white paint is about 5 times that of the red pigment. Therefore, the cost of red paint for color is 5 times higher than that of white paint. This is why some domestic cars have so few colors: simple and low cost. No matter what color paint, its pigment will fade in the sun.

3. Tire maintenance:

Check tire pressure monthly. Tires must be kept in shape with proper care. As time goes by, the pressure in the tires will naturally decrease, so it must be checked once a month. Since the air pressure is often high in "hot" tires, check the tire pressure when the tire is cold.

Ensure that the tires are balanced. After the tires are used, they will be unbalanced, causing the steering wheel and chassis to vibrate, and may even cause steering failure. In this case, you should enter the auto repair shop as soon as possible for balance correction.

Use winter tires. Low temperature will harden ordinary tires and reduce the ground force on smooth roads. If you often drive in cold, rainy, or even icy and snowy days, you can use special rubber and winter tires with sipes.

Urgently deal with flat tires. If a tire collapses suddenly while driving, you should stop immediately, turn on the warning light, and replace the tire. After parking, you must pull on the parking brake, fix the wheels, loosen the screw on the flat tire, and then jack up the vehicle. Remove the citrus and flat tires, and replace them with spare tires. Remove the jack, tighten the screws, and you can continue on the road.

Especially when the tire pattern has been worn out, pay more attention to check the tire wear warning sign.

There are tire specifications, trademarks and factory name standard Lun Yi, production number and maximum load code printed on the side of automobile tires. On the tire shoulders, there is a "△" mark stamped along the equal divisions of the circle. This The sign is the general report signal sign of tire wear.

With the development of expressways, the safety of vehicles at high speeds has been widely valued. Vehicle handling and stability is a necessary condition for vehicles to drive safely. To make the car have good handling stability at high speed, the tire must have good adhesion, that is, the tire must have a good pattern. Experiments have proved that when the tire pattern wears out, that is, when the tire pattern wears to less than 1.6 mm of the remaining groove, the amount of tire slippage increases significantly and the braking distance increases sharply. This not only makes the operation stability of the vehicle worse, but also often causes traffic accidents. For this reason, all countries in the world have made corresponding regulations on the wear limit of automobile tires. The United States stipulates that the wear limit of car tires is that the groove depth is not less than 1.0 mm; the Japanese Automobile Tire Association standard stipulates that the wear limit of tires for trucks and passenger cars is 3.2 mm, and the wear limit for tires for cars is 1.6 mm. my country's national standards stipulate that the radial tire pattern wear limit for cars in is 1.6 mm, and the radial tire pattern wear limit for trucks and passenger cars is 2.0 nim, and requires tire manufacturers to obligately set wear indicators on the tires according to the standard. When the tire pattern wears to the above limit, the wear indicator should be displayed to remind the driver to replace the tire in time.

The specific method is: pick the bottom of the groove on the crown surface of the tire along the tire's circular pattern (this is the case in most countries), and set a 1.6 mm high boss in the axial direction. When the tire pattern of Qingyuan's illegal car was worn to 1.6 min from the bottom of the groove, the groove in this part began to break, and a clear crack appeared. This reminds the driver that the tire must be replaced.

In order to facilitate the inspection, on both sides of the shoulder where the wear indicator is buried, the "△" mark is printed accordingly with the impression to indicate that there is a tire wear indicator in the tire pattern here.

The tire wear indicator is not only a guarantee for the safe driving of the tire, but also as a basis for checking whether the tire is normally worn. When abnormal tire wear occurs, it can be clearly displayed on the tire wear indicator.

A great way to save money on maintenance:

When the vehicle is used for a certain number of years or after a certain mileage, it will enter the maintenance period, and the cost is relatively high. How can we save car repair and maintenance costs on the premise of ensuring quality?

Money-saving strategy one: reasonably determine the maintenance cycle

Scientifically determining the interval mileage of various maintenance operations can not only keep the car in good technical condition, but also save you maintenance and repair costs. Generally, new cars with good technical conditions can extend the maintenance period appropriately if they are used under good operating conditions; while for vehicles with poor technical conditions or poor operating conditions, the maintenance period should be appropriately shortened.

Money-saving strategy two: make full use of free testing

Automobile manufacturers are paying more and more attention to after-sales service, and the benefit that this brings to car owners is that they can often enjoy free inspection activities. Many of these free testing activities seem simple and seem to have no substantive content in the eyes of car owners. In fact, these free testing activities are very beneficial. Car owners can take advantage of these free inspection activities to conduct a comprehensive physical examination of their car, find some potential faults in time, and eliminate these hidden troubles, saving future high maintenance costs.

Money-saving strategy three: dismantle the maintenance assembly as little as possible

Many car owners have this feeling that a certain assembly (such as the engine) of their car is out of control after being dismantled for maintenance, and will be "hospitalized" for treatment every once in a while. In order to prevent the vehicle from entering the maintenance period prematurely, you'd better dismantle the maintenance assembly as little as possible, and use various advanced maintenance equipment and methods to perform disassembly-free maintenance on the car, which can not only avoid the disassembly and maintenance of the car assembly and parts. The unnecessary damage can also greatly accelerate the speed of car maintenance, thereby reducing the total maintenance cost.

Money-saving strategy four: proper use of oil

Proper use of oil includes two aspects: one is fuel oil, and the other is lubricating oil. Improper fuel selection can easily cause malfunctions such as fuel filter clogging, causing the engine to experience unstable idling, poor acceleration, and increased fuel consumption. It will also accelerate cylinder wear and affect engine life. How to choose lubricating oil so that it can meet the lubrication requirements and spend less money? The basic principle is: it can meet the requirements of the vehicle, and only buy the right one and not the expensive one.For example, engine oil. For domestic cars, some domestic SJ grade engine oils can fully meet the requirements, and there is no need to buy imported ones.

Maintenance of six major systems

Intensive maintenance of the lubrication system

The main function of the lubrication system is to effectively lubricate the various parts of the car engine to prevent excessive wear. Under normal circumstances, the car needs to be cleaned and maintained every 5000km-10000km. When the engine is too noisy, the acceleration is weak, and the water temperature is too high, it also needs to be cleaned and maintained. Clean the sludge and other deposits inside the engine, avoid the oxidation and thickening of the engine oil at high temperatures, effectively clean the components of the engine lubrication system, prevent the harm of acidic substances and metal debris, give full play to the lubricating performance of the lubricating oil, and reduce the amount of new lubricating oil. Secondary pollution reduces the wear of engine components, prolongs the life of the engine, and improves the engine power.

Cleaning and maintenance of the fuel system (i.e. cleaning nozzles and valve carbon deposits)

Under normal circumstances, the car needs to be cleaned and maintained once every 10,000km-15,000km, or when you find the engine is trembling, lagging, poor acceleration, black smoke, powerlessness, and fuel consumption. Remove the colloid and carbon deposits inside the system, prevent harmful corrosion, avoid and stop the leakage of seals and water tanks, completely replace the old coolant, improve fuel atomization, restore fuel injection pulse width, improve fuel efficiency, and enhance Engine power. Eliminate small hidden dangers and improve performance.

I hope that the majority of netizens can learn something after reading and apply what they have learned. Mastering certain common sense of car maintenance is a basic skill for car owners. In daily life, as the driving age increases, everyone's understanding of car maintenance will also deepen. Many major and minor problems can be discovered in time for quick solutions.
