What exactly is the four filters of engine oil?

The four filters of engine oil specifically refer to: air filter, gasoline filter, oil filter, air conditioning filter, and oil. Sometimes the auto repair master will deliberately confuse the public, this is still when he is in Kunlun lubrication to change the oil, the master there said, generally in the routine maintenance, only need to replace the oil filter and oil.

As for the other three filters, they can be replaced once according to the road conditions of the vehicle 5000-10000. It is recommended to go to a regular and large place to maintain, by the way, you should also pay attention when changing the oil, at least choose Kunlun lubrication with quality assurance, in short, you should be careful and careful to prevent being deceived.

Air filters, fuel filters, oil filters, and cabin air filters are usually referred to as four filters. Since they serve as a filter, it is only natural that they should be replaced when they are dirty. Many cars are serviced every 7,500 km, and each time we are serviced, the maintenance staff will recommend that we replace them.

Therefore, the quality of the replacement of the "four filters" accessories should be ensured! Accessories such as oil and gasoline have a great impact on the overall condition of the car, so don't be greedy when replacing them, and be sure to choose high-quality accessories. The engine oil should also be changed to the best quality, like the Kunlun lubricating oil said upstairs, this is OK, it is the brand of PetroChina.

The "four filters" of a car, namely the oil filter, fuel filter, air filter, and cabin air filter, all need to be replaced regularly.

Engine oil, oil grid, air grid, air conditioning grid, gasoline grid (diesel car is diesel grid), grid is the meaning of filter.

What are the "four filters" of automobiles? Remember these car tips and save a lot of maintenance costs.

Oil filter, air filter.

and gasoline filters.

Gasoline filters are divided into carburetor type (which has been phased out) and EFI type.

The oil filter is located in the engine lubrication system. The upstream of the filter is the oil pump, and the downstream is the various parts of the engine that need to be lubricated. The machine filter removes harmful impurities from the oil pan and supplies the crankshaft with clean oil.

Connecting rods, camshafts.

Moving pairs such as superchargers and piston rings play the role of lubrication, cooling and cleaning, thereby extending the life of these parts.

An air filter is a device that purifies the air. If the dust, sand particles and various impurities in the air directly enter the engine cylinder for combustion, it will accelerate the wear and tear of the engine, thereby reducing the service life of the engine and even causing serious damage to the engine.

What does the so-called three-filter change mean for car maintenance? How often do I need to change it? When you maintain your car, you generally have to change the oil and three filters.

So what exactly is the "three filters"? There are really different ways to say this question, so let's tell you what the so-called "three filters" mean, what do they do, and how often should they be replaced? The three filters of automobiles refer to air filters, oil filters and gasoline filters, their role as the name suggests, is to filter and purify any gas and liquid that enters the inside of the automobile engine, so as to protect the engine and improve the efficiency of the engine.

Air filter. The function of the air filter is to filter the air before it enters the cylinder, removing impurities, dust, grit and other foreign substances entrained in it. Typically, air filters are cleaned and serviced at intervals of 6,000-8,000 km.

Sometimes, even though the replacement mileage has not arrived, the inside of the filter is already covered with dust or oil and must be replaced immediately. The function of the air filter is mainly to filter out impurities or dust in the air and let clean air enter the cylinder. Time has proven that if the engine is not equipped with an air filter, its life will be shortened by 2 3, in addition, the air filter also has the effect of reducing the noise of the intake air.

Oil filter. The inside of our iron oil filter is also a paper filter, last time a fan asked, so I cut a filter a few days ago, the financial information of the iron shell has been developed for many, many years, and now more and more cars in order to save energy, are just paper oil filters, our oil filters are replaced with random oil every time we change the oil.

Gasoline filter. The function of the gasoline filter is to purify the fuel, in the process of gasoline storage, transportation and filling, it is inevitable to mix some impurities or water, once it enters the oil supply system or engine cylinder, it will accelerate the wear of the oil supply system and engine cylinder. If the air filter is too dirty, the car becomes difficult to start, and the power increase is slow when you step on the accelerator, and generally this filter is a one-time non-detachable and washable type, and it is generally considered to be replaced when driving to 30,000 kilometers, or it can be replaced according to the manufacturer's standard.

The three filters of motor oil include oil filter, air filter, and gasoline filter. Why do you need to change the oil filter for 5000 kilometers and then change the oil three filters for 5000 kilometers, because the car needs maintenance to ensure the normal operation of the car, etc., you may be talking about the previous oil change, machine filter, air filter, gear oil. And next time it's the oil, filter, air filter and steam filter!

Among them, the oil filter and steam filter need to be replaced every 5000km, while the gear oil and steam filter need to be replaced every 10000km!

The three filters of engine oil refer to: engine oil and oil filter. Air filter.

Gasoline filter engine oil and oil filter 5000km change once Air filter and gasoline filter can be changed once in 10000km - 15000km Gear oil go to 4S to ask, a car and a car are not the same. For example, Geely car 12,000km for one time, Maliu 30,000km,

Hello is oil filter, fuel filter, air filter.

An oil filter is also known as an oil grid. It is used to remove impurities such as dust, metal particles, carbon precipitates and soot particles in the engine oil and protect the engine.

An air filter is a device that removes particulate impurities from the air. When operating piston machinery (internal combustion engines, reciprocating compressors, etc.), air filters must be installed if dust and other impurities are inhaled into the air, which will increase the wear and tear of the parts.

There are three types of fuel filters: diesel filters, fuel filters and gas filters.

The three filters of engine oil refer to the oil filter, gasoline filter, air filter, and air conditioning filter.

Engine oil can also play a role in protecting and cooling the engine, in addition to being a sealant and rust inhibitor, the acidic substances produced by automobile power combustion are very corrosive, and this role of engine oil plays a good role in protecting the engine.

Note. Oil filters, fuel filters, air filters and cabin air filters are commonly referred to as the "four filters". They both serve as filtration, but the replacement replacement cycle is slightly different

The oil filter replacement interval is generally 5000 km.

The fuel filter replacement interval is generally 10,000 km.

The replacement interval of the air filter is generally 10,000 km.

The cabin air filter replacement interval is generally 20,000 km. Hope!

Gasoline and diesel) oil rate, machine (oil) filter, air (gas) filter.

The three filters of the engine oil are as follows:The so-called oil three filters here refer to "air filter", "oil filter" and "fuel filter silver squire". The "three filters" perform their respective duties when the engine is running, and are in charge of the engine's airway, oil circuit and lubrication system, and any party "vacation" will make the engine "sick".

With the improvement of the quality of auto parts, the replacement cycle of "fuel filter" of many models has become longer, so some people think that "air conditioning filter" should be counted as one of the three filters, but so far the most scientific view is still the first one.

Characteristics of the oil:The engine oil on the market can be divided into two types: mineral oil and synthetic oil due to its different base oils (vegetable oil is not counted due to the scarcity of production). Synthetic oil is further divided into:

Fully synthetic and semi-synthetic. Lubricating oil base oils are mainly divided into two categories: mineral base oils and synthetic base oils. Mineral base oils are widely used in large quantities (about 95% or more), but some applications require the use of synthetic base oil blends.

The three filters of motor oil refer to air filters, oil filters, and gasoline filters.

Gasoline filter is referred to as steam filter, and its main function is to remove impurities from gasoline. If the gasoline filter is too dirty or clogged, it will be slow or unable to get up when the fuel pedal is filled, and the vehicle will have difficulty starting, and sometimes it may take several times to ignite it. The gasoline filter is replaced every 40,000 kilometers.

Air filters, also known as air filter cartridges, styles, etc., are mainly used for air filtration in engineering vehicles, automobiles, agricultural locomotives and various precision operation rooms. The engine has to suck in a lot of air when it is working, and if the air is not filtered, the dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and the cylinder.

How it works

The oil filter chamber riser, also known as the oil grid, is mainly used to remove impurities such as dust, metal particles, carbon sediments and soot particles from the oil, so as to protect the engine.

The oil filter will have high requirements for the filter paper, because the temperature of the oil varies from 0 to 300 degrees, and the concentration of the oil will also change accordingly under the drastic temperature change, which will affect the filtration flow of the oil. The filter paper of a high-quality oil filter needs to be able to filter flammable materials under severe temperature changes while maintaining sufficient flow rates. The oil filter is decided based on the oil change interval, and each time the oil is changed, the oil filter is replaced with a new one.

The three filters of engine oil refer to air filters, oil filters and gasoline filters, which are used for decontamination and storage, so timely cleaning will help improve the working environment inside the car body.

1. Air filter.

The function of the air filter is to filter the air before it enters the cylinder to remove impurities, dust, sand and other foreign substances entrained in it. Under normal conditions, the cleaning and maintenance interval of the air filter is 10,000 to 15,000 km. Sometimes, however, the inside of the filter is covered with dust or oil and must be replaced immediately, even though the replacement time or mileage has not yet arrived.

There are two types of air filters: dry and wet, and most cars use dry air filters.

2. Oil filter.

Its function is to remove all kinds of impurities in the oil and ensure the normal operation of the lubrication system. The oil filter can be changed at the same time as the oil is changed. Note:

When installing a new filter, do not overtighten it with a filter wrench to prevent damage. If the oil filter is clogged, it should also be replaced or the dirty filter should be cleaned, dried and reused. If the filter gasket is damaged and leaks, it needs to be replaced, or the original gasket shape should be cut out with a cloth of comparable thickness.

3. Gasoline filter.

The gasoline filter should be drained of water and sediment from the filter once a week, and the cleaning and replacement interval is generally 5,000 to 10,000 kilometers. The replacement requirements should also be subject to the requirements of the vehicle's instruction manual.

The three filters of automobile Zheng chain residue engine oil are air filters, oil filters and gasoline filters, and their functions are: shouting.

1.Air filter: to ensure that the air entering the engine is clean;

2.Oil filter: filter oil to ensure the normal operation of the engine;

3.Gasoline filter: Ensures fuel is clean and prevents air lock-up.

Automobile engine oil can filter the air and gasoline of the automobile engine, lubricate and protect the engine, and improve the working efficiency of the engine. Timely cleaning of car oil can give full play to the performance of the engine, reduce the engine failure rate, and help to prolong the service life of the engine.

1.Engine oil, also known as lubricating oil, can effectively protect the engine, also known as the blood of the engine. Filters, also known as oil filters, mainly play the role of filtration.

The oil circulates inside the engine and filters the oil through the oil filter to ensure that the oil that is returned to the engine is clean.

2.Motor oil is made up of two parts, the base oil and the additives. Base oil is the main component of lubricating oil and determines the properties of lubricating oil.

The addition of celery retarder is to make up for the lack of performance of the base oil and to impart some new properties. Higher than base oil. The oil filter can remove dust, metal particles, and some impurities from the oil, which can effectively protect the engine.

People tend to focus on the importance of engine oil and ignore the role of machine filter. Some car owners even think that they only need to change the oil during maintenance, and the machine filter is just a machine that filters the oil, and it can save costs if it is not replaced. If you understand what a filter is and what it does, it won't feel irrelevant.

What is machine filtration?

The engine filter, that is, the oil filter, is located in the engine lubrication system, which is mainly to remove impurities such as dust, metal particles, carbon precipitates and soot particles in the engine oil, so as to achieve the purpose of protecting the engine. The composition of the filter can be divided into two parts, the upstream is the oil pump, and the downstream is the parts of the engine that need to be lubricated. At the same time, the oil filter is divided into full-flow type and split-flow type.

The full-flow filter is connected in series between the main oil tract and the oil pump, and is able to filter out all the lubricating oil entering the main oil channel. The split-flow cleaner is connected in parallel with the main oil duct and can only filter part of the lubricating oil from the oil pump.

The role of the oil filter element

In the process of engine operation, mechanical impurities such as dust, metal wear, and carbon cleaning will continue to be mixed into the engine oil, and the oil will be oxidized by air and combustion exhaust gas to gradually produce gum. After the mechanical impurities and gum are mixed, sludge will be formed, which will easily cause the blockage of the oil circuit and accelerate the wear and loss of moving parts. The function of the machine filter is to filter out the harmful impurities in the oil from the oil pan, supply pure engine oil, and play the role of lubrication, cooling, cleaning and cooling, so as to prolong the life of these parts.

In fact, cars not only have oil filters, but also air filters and gasoline filters, which are collectively known as the "three filters of automobiles". They increase the efficiency of the engine, if"Three filters"Timely cleaning and maintenance can fully realize the performance of the engine, reduce the engine failure rate, and prolong the service life of the engine. Usually the air filter needs to be replaced every 20,000 kilometers, and the gasoline filter needs to be replaced every 40,000 kilometers, which is subject to the manufacturer's maintenance manual.
