How many liquids are there in a car? Why?

Our cars themselves need to have seven fluids, such as brake fluid.

Gasoline, oil, antifreeze.

And glass water, etc., why do you need these liquids? Mainly because the car itself needs to work needs these liquids to participate, if any kind of liquid is removed, then our car will have some problems in the process of driving, so our car needs the existence of these liquids, so that we can drive safely.

One of the most important liquids is motor oil. Because engine oil has a great effect on the engine of the car, if the car lacks engine oil, it is equivalent to our heart ischemia.

It is the same reason, so we must check whether the condition of the engine oil is good before driving, whether it can ensure that the car will not encounter the consequences caused by insufficient oil during driving, of course, the engine oil is also good and bad, which also depends on what kind of oil our car is most suitable for, which can ensure the service life of the car.

Another and more important one is antifreeze. We must not underestimate the antifreeze, the ordinary owner of the antifreeze may not pay much attention, but the antifreeze also needs us to replace it regularly, usually do not pay attention to the driving, it will cause the engine to overheat, cause certain damage to our car driving, reduce the service life of the car, in the usual maintenance process, we must pay attention to the replacement of antifreeze, may bring a good cooling effect to the engine.

With the continuous development of China's automobile industry, cars have brought good convenience to our families, and also improved our lives, but cars also need someone to care for them, such as when we refuel the car, we will consider the quality of gasoline, whether it damages the engine, etc., these are a kind of care for the car, the car has been an indispensable part of our life, and it is also an indispensable and important means of transportation in our life and work.

Extending the life of the car is also something that every veteran driver should do.

There are 10 kinds of liquids in automobiles, namely windshield washing fluid, coolant, fuel, air conditioning fluid, brake fluid, urea water, glass glue, engine oil, etc.; This is because these fluids can promote the life of the car and can also provide the power to make the parts between the cars more lubricated.

There are 9 types of liquids in the car. These liquids are gasoline, antifreeze, engine oil, gear oil, shock absorber oil, refrigerant, glass water, brake fluid, lubricating oil. Because cars need these to work better.

There are a total of 7 types of liquids in cars; For example, glass water, antifreeze, gasoline brake fluid, engine oil and other liquids are used in various parts of the car to cooperate with each other, and these fluids are needed for lubrication or auxiliary functions in this process.

There are 7 kinds of fluids in the car, there are brake fluid, engine oil, gasoline, antifreeze, glass water, lubricating oil, air conditioning refrigerant, because they are needed in the car.

As follows:

1. Antifreeze: It can be seen from the name that antifreeze can bring antifreeze to the engine cooling system, and the antifreeze has cooling, anti-corrosion, anti-boiling, anti-rust, etc., which is very important to the engine cooling system.

2. Wiper water: In hot days, when the wipers are dry, scraping and cleaning our glass can eliminate the dust on the glass.

3. Battery water: In the past, many large cars had to add battery water to their batteries, but now many cars have been changed to batteries without cover.

4. Engine oil: Engine oil should be known to every child, because we must change the engine oil every time we do maintenance, and the influence of smelling engine oil is very large, which can supply our engine with cooling, smoothing, sealing, rust prevention, shock absorption, buffering, cooling and so on, it can be said that engine oil is the most important oil for our engine.

5. Biased engine booster oil: In the hydraulic bias assist system, we will be equipped with our biased engine booster oil, and use the disposal to help inform that there is a bias to supply biased assistance to the bias machine, but now many cars have been applied, and the electronic bias booster system has also reduced the bias engine booster oil.

6. Brake oil: Brake oil also belongs to hydraulic oil, when the brake pedal is pressed, the hydraulic pressure will be notified to the pump to brake the car.

There are a total of 9 kinds of liquids in the car, which are fuel or diesel, gear oil, shock absorber oil, brake fluid, antifreeze, engine oil, air conditioning refrigerant, glass water, and lubricating oil. Gasoline is currently the most used fuel.

Gasoline is one of the most widely used light petroleum products, and it is also the main automobile fuel for cars.

It is mainly used as a fuel for automobiles, airplanes, motorcycles, etc., and can be divided into three types: vehicle gasoline, solvent gasoline, and aviation gasoline according to different uses.

Gasoline has the characteristics of evaporative letter wheel, anti-explosion, stability, safety and corrosiveness, we often see different grades of gasoline in the slippery letter, where the label refers to the octane number, and the octane number represents the anti-knock property of gasoline, the higher the octane number, the better the anti-knock performance.

In addition, high-octane gasoline can also meet the needs of high-compression ratio gasoline engines, the higher the compression ratio of gasoline engines, the higher the chance of thermal efficiency, which can save fuel and fuel consumption.

Millions of car purchase subsidies.

There are a lot of fluids in the body of the car, there are 5 kinds of fluids and 3 kinds of liquids. These include engine oil, brake fluid, steering fluid, transmission fluid, differential fluid, coolant, glass water, and battery water. These liquids play a very important role in the car, which can ensure the normal operation of the car, so as the owner of the car, it is also necessary to have a basic understanding of the cycle of replacing these liquids.

Oil and glass water are consumable liquids that need to be refilled after use, while other liquids need to be replaced.

What are the causes of oil leaks in cars?

I believe that many car owners will find that they have oil leakage in the process of driving, which may be because there is a problem in a certain part of the car, resulting in the oil leakage of the car, generally there are three possibilities, one is that the car is used for too long, resulting in the aging of the seal, and there is also a possibility that the auto parts have failed to cause leakage, in addition to the damage caused by accidentally knocking the chassis while driving. The problem caused by oil leakage can be large or small, but a puddle of water may be condensed by the air conditioner in winter, which is a normal phenomenon, but if the leakage is engine oil or brake fluid, it needs to be paid attention to and dealt with in time.

How can you tell which fluid?

When there is an oil leak, you want to determine what kind of oil it is, you can observe the color of the oil, the clean oil is a transparent color, but with the increase of the mileage of the car will become dark brown, some longer will become black, the color of the transmission oil is red and yellow, the color is relatively clear. The color of the brake fluid is very similar to the engine oil, but the smell of the brake oil is more pungent. The color of the antifreeze is colorful, the texture is more like water, and there is no lubrication, but if there is just a puddle of liquid on the ground, then it belongs to the condensation of the air conditioner.

Finally, as a car owner, you must understand the basic situation of the liquid inside the car, so as to ensure that you can deal with it correctly when there is an abnormal situation in the car.

There are a total of 7 kinds of liquids: lubricant, brake fluid, antifreeze, glass water, engine oil, diesel, and air conditioning refrigerant; This is because the car cannot run well without these 7 liquids, and only the existence of these liquids can make the car run better.

There will be about 10 kinds of liquids, because the main liquid in the car body is organic oil, antifreeze, glass water, air conditioning refrigerant, gear oil, brake oil, shock absorber oil, lubricating oil. And these liquids are indispensable.

There are a total of 9 types of liquids. Because the liquid determines every part of the car, every part of the car, and also determines the normal operation of the car.

Gasoline, engine oil, gear oil, brake fluid, shock absorber oil, antifreeze, glass water, air conditioning refrigerant, and lubricating oil.

Engine oil: The maintenance interval of the car and the oil product are different, so the replacement cycle is different. Generally 5000 10000km replacement.

Gear oil: The change interval is different for different gearboxes. Generally 28,000.

Brake fluid: Probably 2 to 3 years.

Antifreeze: 2 years.

Glass of water, like gasoline, has to be refilled when it is gone.

The refrigerant of the air conditioner is like the freon of the air conditioner, if it is not cold, it is lacking.

You are indeed buying a car for the first time.

The car's maintenance manual has clear terms about what liquids are available, when to replenish them, and how much to replenish. Each vehicle is different, and you need to follow the instructions of each one. How to look at the specific amount, various vehicles are different, and some can be seen, such as:

Oil, coolant. Some are invisible, such as: brake fluid, glass water, steering fluid, booster oil, etc.

For example, the oil change interval generally ranges from 5,000 km to 15,000 km; Transmission oil, some cars do not need to be replaced for life, and some are changed once every two years, which varies greatly.

The types of fluids I tell you are: engine oil, coolant (not water), glass water, power steering oil, brake fluid, transmission fluid (gear oil), battery electrolyte.

It is clearly marked on the car manual. Don't worry!!

Power oils such as gasoline or diesel and their additives, power tuning fluids, engine oils, glass water, water.

Brake fluid, glass water, steering fluid, booster oil and coolant.

Antifreeze has ethanol type, ethylene glycol type, and glycerol type. The full name of ethanol-based antifreeze is antifreeze coolant. It plays 3 roles, a vehicle does not start to prevent freezing, because the antifreeze is in the cylinder, the liquid becomes solid and the volume will expand, so it will freeze and crack the cylinder.

Another function is to cool the engine after the vehicle has been started. Prevent the engine temperature from being too high, causing damage to the engine. Antifreeze also serves to manage rust and prevent excessive limescale from causing clogged lines.

Antifreeze is generally replaced once every 2 years and 6w kilometers.

Long-term failure to replace the antifreeze will lead to changes in the quality of the antifreeze, which will reduce the internal anti-rust quality, and the radiator and pipes will be damaged. It will also affect the boiling point and freezing point parameters, affect the anti-freezing effect or cooling effect, and harm the engine. Don't wait until the antifreeze turns black to replace it, the blackening of the antifreeze means that the antifreeze has deteriorated badly.

Limescale is also formed a lot. There is already damage to the pipeline. Therefore, every time you do maintenance, you can use a freezing point meter to detect the freezing point value of antifreeze.

If the freezing point is too high, the antifreeze has deteriorated and needs to be replaced.

There is also engine oil, transmission lubricants, brake fluids, power steering oil, battery fluids, butter.

Common liquids used in automobiles include gasoline, which is used as fuel; cooling water or antifreeze; brake fluid; Gear oil in the gearbox. Everyone is no stranger to gasoline, but they are not very familiar with several other liquids. Let me briefly introduce you to this knowledge.

First of all, the antifreeze is introduced: glycerol type, methanol type, ethanol type. The glycerol type has poor fluidity, and the latter two have poor oxidation and safety because of their volatility.

Therefore, it is gradually replaced by ethylene glycol. When selecting, pay attention to the antifreeze that is 10 times lower than the temperature of the car use, and different models cannot be mixed.

Engine oil is classified according to the quality of engine oil abroad, and S is used to indicate gasoline engine oil. Arranged from SA to SH, the quality of the oil rises by one level for each letter after S. The viscosity of motor oil is generally expressed in W.

The higher the number before w, the better the fluidity of the engine oil at low temperature, and the change with temperature is also very small, which is suitable for winter use. There are generally two types of engine oils: synthetic engine oil and mineral engine oil. Synthetic motor oil has become the first choice for medium and high-grade automotive lubrication because of its lubricity and low amount of oil scale after oxidation.

There are three types of brake fluids: alcohol, mineral oil, and synthetic. Alcohol-based brake fluids have a low boiling point and are less stable at low temperatures.

The mineral oil type is suitable for a wide range of temperatures, but it has a dissolving effect on the rubber parts in the brake system, which can cause oil blockages and oil leaks. The requirements for rubber parts are relatively high. The swelling rate of the synthetic rubber parts is small, and the viscosity of the oil changes with temperature is also small, and this kind of brake fluid is widely used in high-power, heavy-duty, high-speed automobiles.

Gear oils are classified according to the level of viscosity and the properties they use. Internationally, according to the kinematic viscosity of gear oil at 100 and the maximum temperature under the condition of 150Pa, it is divided into: 70W, 75W, 80W, 85W, and the one with W is suitable for use in winter.

It is advisable to choose the appropriate viscosity grade according to the minimum and maximum temperature of the place where the vehicle is used.

The performance is divided into six grades: GL-1 to GL-6 according to the load capacity of the gear and the use of different occasions. For the main transmission with harsh working conditions, hyperbolic main transmission and medium and high-end cars, GL-4 and GL-5 gear oil should be selected.

For general mechanical gear transmission, GL-3 is sufficient.
