seabet io

When the car lubrication system is working normally，Motor oil is constantly circulating in the engine，Forced lubrication of the surface of each seabet iosports friction，and take away the abrasive and friction heat from the surface of various friction，Due to effectively splashing towards the wall of the tank，It guarantees the sealing and lubrication effect of the piston ring and the wall of the cylinder under high temperature and high pressure。

The cause of the deterioration of the oil

The centrifugal oil filter and full -current paper oil filter used by the general car engine，Good quality to maintain the good quality of the oil，But with the increase of the mileage of the vehicle，The filtering ability of the engine oil filter is gradually reduced，Unburned fuels accumulated in lubricating oil、Water、Burning generics (such as carbon deposits、Coke)、The oxidation of lubricating oil (glue、asphalt、a variety of acids, etc.)、Sand particles、Dust、Black and non -ferrous metals wear more and more particles。

Glamination deposited in the burning room and the top of the piston，It can form carbon deposits and cause the engine abnormal combustion; piston ring、There is glue on the valve lever，It will kill these parts to be killed and sticky，exacerbated the wear of various components of the engine。

The cause of the deterioration of the oil is the main point:

① The dandruff deposits produced by the friction of the machine;

② When burning，Paint film generated by high temperature oxidation、Estated material glue and carbon accumulation;

③ The dust of the oil from the outside world;

④ The acidic substance generated during burning;

⑤ Cabinching device of the crankshaft box，Poor oil for oil，Machine oil is heated naturally to form glue;

⑥ Unduated gasoline mixed oil in the mixed gas、Cooling water seepage human oil in the water cover

Damage to the cylinder pad or other reasons causes the cylinder or crankshaft box to water。When the water content exceeds 0.1% time，The antioxidant added with oil、Pure dispersant, etc. will fail，Therefore, accelerate the oxidation process of the oil。When the oil contains more water，Motor oil lubrication deterioration，Decreased viscosity，Poor oil -resistant friction effect of oil film，Light causes the oil to deteriorate prematurely and rust the machine，Direct、Burning tiles and other serious mechanical accidents。

⑦ The burning room is not tightly sealed        

No found after the piston ring or cylinder is worn，Learning fuel into the crankshaft box for a long time and contact with motor oil，Long -term high temperature causes oil to deteriorate、Decreased viscosity、Poor effect of the oil film, seabet ioetc.。So here，The lubrication and sealing effect of the oil film on the piston ring and the cylinder wall gradually fails，The friction between the Pistons and the Cylinder Wall is constantly increasing，Long -term，Whenever a piston workmanship，The number of high -temperature flames enters the crankshaft box, the number of times increases，Keep a malignant cycle，Eventually leading to the oil lubrication failure in the crankshaft box，Eventually leading to problems such as burn tile。

⑧ Long -term do not change motor oil

I don’t know if you have such a sigh。New car landing，Love car is like life，Worried that there are problems with the car protection of the car and there are problems，Maintenance on time or even advance，Machine oil selection best brand。After a long time，The owner will gradually become lazy，The enthusiasm for changing the oil every 5000 kilometers to 7500 kilometers，Most of the owners who do not change the oil at 15,000 kilometers in the end。

Judgment of the deterioration of oil

1. Observation of the color of the oil

Lighting method      

On the day when the weather is fine，Use a screwdriver to lubricate oil，with horizontal plane to 45 degrees angle。Comparison of Sunshine，Observation of oil droplets，Under light，You can clearly see that there is no abrasive in the lubricant oil，can continue to act，If there are too many abrasives，Should be replaced with lubricating oil。

High -quality oil is translucent yellow brown，When there is water in the oil, it is brown，When the engine runs for a period of time，Machine oil is milky white，Anding with foam。Machine oil is black and too much of the mud and iron dumbs，or too much carbon particles in the oil。Draw out the oil label to observe whether the dialogue line is clear，When the oil on the oil ruler is not available, please engrav the line，It means that the oil is too dirty，Need to be replaced immediately。

Of course，To see if the oil is deteriorated with the eyes, it requires the precipitation of experience to exert its effect。So is there a magic weapon with a low price and good test effect? have!。

Slow and qualitative test strip is priced at 9-11 yuan (100 pieces of one box) each time the oil inspection requires a test strip，That is, the cost of the material for each inspection is about 1 cents。Slow and qualitatively try to determine the ion and chemical composition，It can determine whether the sample contains a certain amount of substance，Among them, test strips can be detected by the oil to determine the condition seabet loginof the different components contained in the oil，To determine whether the oil has been aged。

Test method:

Take out the oil ruler，Machine oil on a drop of oil ruler at slow and qualitative test strip，Place the test strip level，Waiting for 24 hours。It is found that the following three important ring -shaped areas will appear below after a 24 -hour static test paper。

1, sedimentary ring:The center of the spots is where the coarse particles in the oil are concentrated，The depth of the color of the sedimentary ring can roughly judge the degree of pollution of oil。

2, diffusion ring:The ring belt on the periphery of the sedimentary ring is called the diffusion ring，It is a trace left by the fine particles suspended in the oil out of the oil。The thinner the particles，The farther the diffusion。The width of the diffusion ring and the uniformity of the color is an important factor，It indicates the dispersion ability of the additive in the oil to pollute impurities。

3, oil ring:The peripheral oil ring of the diffusion ring，Color from light yellow to brown red，Indicates the degree of oxidation of the oil。

Four grades of the quality of oil from the diffused oil from the test strip:

Level 1:There is no obvious boundary between the sedimentation area of ​​the oil spots and the diffusion area，Uniform color of the entire oil spots，The oil ring is light and bright，Good oil quality。

Level 2:Depression of Seven Circle，The diffusion ring is wider than，There are obvious dividing lines，The oil ring is yellow with different depths，Oil quality pollution，Machine oil can still be used。

Level 3:Dark black，Depression dense，Swallowing ring narrow，The color of the oil ring becomes darker，Oil quality has deteriorated。

Level 4:Only the central sedimentation ring and the oil ring，No diffusion ring，The sedimentary ring is dark and thick，Not easy to dry，The oil ring becomes dark yellow and light brown，Oil quality has been oxidized and deteriorated。

2. Observe oil flow

Slowly fell to another empty cup with a cup of machine oil，Observe its flow，The oil flow of good quality motor oil should be slender、Uniform、continuous continuous; and metamorphic oil will be oily.。

Three, the feel does not have any foreign body

Pour the oil on the thumb between the thumb and the index finger，The feel should be lubricated、None abrasive、No friction，If you feel that there is a large friction with sand grains such as sand particles，It indicates that there is iron dumbs in the oil、Plela and impurities。

seabet io4. Machine oil should be transparent without foreign objects

On the days of the sun or choose a place with better light，Check the oil with the oil inspection stick or the oil ruler and then observe the oil droplet condition with the sun，If you see no abrasives in the oil，Description can continue to act; if too much abrasives，Instructions that the oil has deteriorated and cannot be used。

5, no odor        

Any oil that stimulates the smell of smell is deteriorated or inferior oil，Good oil should have no special odor，Only slightly aromatic。

Summary of the deterioration of oil

Lubricating machine oil is dark black after deteriorating oil、Many foam and have experienced emulsification，grind with your fingers，No sticky sensation，Send astringent or odor，Drop on the white test paper is dark brown，Many yellow infiltration areas or many black spots。If it is not replaced in time, it will accelerate the wear of the components，Affects the service life，Even a security accident，So，It is important to check whether the lubricant oil is deteriorated and replace the new motor oil in time。
