The 2009 Liwei engine oil has become much less

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. Burning engine oil is caused by the following factors, as long as the following problems are solved, burning engine oil can be solved.

There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and lead to the burning of engine oil, making the vehicle appear:

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem. In the past, the problem of burning engine oil could only be solved by dismantling and repairing, but now there is no.

The solution to the problem of dismantling and repairing engine oil can be learned about.

If it is caused by engine oil, it is recommended to use a better car oil, and it is recommended to use a fully synthetic SN level Dark Horse King car machine.

Oil, a certain Taocai is more than 200 barrels of 4L, and it can run more than 10,000 kilometers! It is very cost-effective and effectively solves the problem of carbon deposition and burning engine oil!

Expansion: Engine oil, that is, engine lubricating oil Huai ridge, has the functions of lubrication and wear reduction, auxiliary cooling, sealing and leakage, lead wide penetration, anti-rust and anti-corrosion, and shock absorption and buffering. The difference between oil and oil: it is made up of base oils and additives.

Engine oil burning is an abnormal situation.

There are four types of engine oil burning:

1. The EGR valve is damaged, and the oil exhaust gas of the engine enters the combustion chamber, causing the oil to burn. Judgment method: Remove the air intake pipe and check whether there is obvious oil stain near the EGR valve. Solution: Repair or replace the EGR valve.

2. The gap between the engine valve and the valve guide is too large or the valve oil seal is aging and the seal is not tight, so that the oil enters the combustion chamber from the valve position, resulting in oil burning. Inspection method: Open the oil filler cap to check whether there is blue gas spraying, if there is air leakage; None good.

Solution: Replace valves, valve seals, valve guides, etc.

3. The engine cylinder head gasket burns through, causing the oil to leak into the combustion chamber from the oil channel, thereby burning the oil. Judging method: remove the spark plug and check the cylinder pressure, if the air pressure of the adjacent two cylinders is similar and the air pressure is lower than the standard value, there is a cylinder string, which may cause oil leakage.

Solution: Replace the head gasket.

4. The gap between the piston, piston ring and the cylinder wall is too large, causing the oil to enter the combustion chamber for combustion. Judgment method: pull out the oil dipstick and observe whether there is a blue gas spray at the mouth of the oil dipstick.

Yes, burn the engine oil; None, do not burn engine oil. Solution: Engine repair, replacement of pistons, piston rings, cylinder liners, etc.

It's definitely not normal to burn engine oil. The main reasons for burning engine oil: 1. Use engine oil with poor quality or viscosity grade that does not meet the requirements. In addition, too low or too high oil viscosity can lead to poor engine lubrication, increased wear of piston rings and cylinder walls, and reduced sealing performance, resulting in oil burning.

2. The matching gap between the piston ring and the cylinder wall is too large, the piston ring is improperly installed or the sealing is poor, and the oil on the cylinder wall enters the combustion chamber, causing the phenomenon of burning the engine oil; In addition, poor sealing performance of the valve seal, damage to the crankcase forced draft valve (PCV) or crankcase vent blockage can cause excessive pressure in the crankcase to cause the oil to enter the cylinder with the crankcase gas and participate in combustion. 3. Burning engine oil caused by excessive oil filling. When the oil is filled above the center line, the part of the engine lubrication process that passes through splash lubrication will be too much into the combustion chamber due to the high oil pressure.

4. Oil leakage from turbocharger. The turbocharger is mounted at the front of the exhaust pipe and operates at a very high temperature, and the turbine and pump wheels can reach 120,000 revolutions per minute when the engine is running at full load. The turbine shaft has oil-lubricated floating bearings, and the car has one oil passage to the turbocharger.

Oil leaks from pipes or bearings can allow oil to seep from the turbocharger into the exhaust pipe. When the exhaust pipe temperature is high, the oil is baked and discharged into blue smoke. 5. There is leakage in the valve oil seal, which means that the oil leaks into the combustion chamber through the valve oil seal.

End method to prevent oil burning: 1. Use engine oil that meets the technical requirements of the vehicle. Many car owners never read the vehicle manual, and they don't know what quality and viscosity grade oil their vehicles use for a few years, and there is a lot of arbitrariness in the use of engine oil. When using engine oil, one is to pay attention to the quality index, and the other is to pay attention to the viscosity index.

The quality index refers to the grade above SL as much as possible, and the viscosity index should be strictly in accordance with the provisions of the viscosity index in the automobile manual, and cannot be too low or too high. 2. Avoid frequent rapid acceleration and long-term ultra-high-speed driving. When the engine rotates at ultra-high speed, it is easy to break the lubricating oil film, resulting in poor lubrication and dry grinding of the rotating parts, and when it becomes a regular operation, it will make the engine wear abnormally and burn the oil, therefore, maintaining economic speed is one of the best ways to prevent the phenomenon of burning oil.

3. The oil must meet the specifications when filling. When the oil filling volume exceeds the center line, the repairman should be asked to pump out the excess oil, in addition, the oil volume should be observed before the next day. 4. If you find that the engine oil is burned, go to the maintenance station for inspection as soon as possible.

If it is due to engine failure (such as poor piston ring sealing, valve oil seal leakage, cylinder gasket leakage, etc.), you should go to the maintenance station as soon as possible to check and repair the fault as soon as possible.

Not normal, there are a few generally burned engine oil.

Situation: 1Oil leaks into the cylinder from the valve.

This situation is generally caused by the lack of tight sealing of the valve oil seal. The solution is to replace the valve seal. If the valve guide is severely worn.

It is also necessary to replace the valve guide or even the valve. 2.Caused by leakage of cylinder piston rings.

For example, the oil ring scraping capacity is reduced, or the air ring leaks, resulting in too high pressure in the crankcase, and the large airflow through the crankcase ventilation brings too much oil mist into the intake pipe. Causes oil to burn. If this condition is mild, the ring can be replaced.

In serious cases, only the piston group (including the piston ring) and the boring cylinder can be replaced, which is an overhaul. You can check the cylinder pressure first, if it is normal, it is not a big problem, just change the valve oil seal.

Abnormal oil burning indicates that there is something wrong with the engine.

Hello, not normal. Whether it is burning oil or leaking engine oil needs to be checked clearly.

Ask the car master if you have any questions, if you have any questions, please ask.

Magic pressure, solve the problem of burning engine oil, and fully protect the engine.

After a period of driving, the engine is scarred by increasing wear and tear from a new state, which leads to noise, idle shaking, power loss, oil burning, fuel consumption and other undesirable conditions.

The magic pressure can be instantly attached to the surface of the engine, repair the wear and tear marks of the engine, fill the gap between the cylinder wall and parts, solve the problem of burning engine oil, and protect the engine for a long time

1. Change the engine oil 2-3 times or use this product once after driving about 10,000 kilometers;

2. For new cars below 20,000 kilometers, add 125ml of friction pressure (i.e., half a bottle) for more than 10,000 kilometers, and add 250ml of friction pressure (one bottle) each time

The common causes of oil burning problems are as follows:

1. There is too much oil in the oil pan, which exceeds the line of the engraving line, so that the splash oil is too much;

Exclusion method: add engine oil according to the regulations during maintenance;

2. The piston ring is worn, and the side clearance is too large;

Exclusion method: replace with a new part;

3. The oil ring and conical air ring are installed when reverse;

Exclusion method: pay attention to the installation mark, there is "up" and the outer circle chamfer towards the piston top direction;

4. The piston-cylinder liner is worn too much;

Exclusion method: replace with a new part;

The valve-valve guide fit gap is too large, and the lubricating oil enters the cylinder for combustion;

Exclusion method: check and identify the fit gap, and replace the new parts when the limit is exceeded.

The above is the traditional solution, and now there is a product on the market that works well, and you can suggest that you use it, the magic pressure of the Taiwan BOD brand. I heard from friends who have used it that the effect is good.

Most of the engine oil burned by Nissan Liwei is caused by the piston ring being trapped by carbon deposits. Relying on the addition of high-viscosity engine oil to continue life is only an expedient measure to cure the change. When the oil enters the combustion chamber to participate in the combustion, more carbon deposits will be formed, and the high base of carbon deposits will lead to the aggravation of the burning of engine oil, forming a vicious circle.

In the long run, it will cause cylinder wall strain, or even cylinder burst, and finally the engine can only be disassembled for overhaul.

Four reasons why you burn engine oil.

A ...If you don't clean the oil circuit for a long time or don't do effective oil circuit cleaning, you can use detergents at will, and using detergents and detergents with laughter effects are two different things;

IIThe antifreeze replacement cycle is too long or not changed at all;

IIIThe oil change interval is too long;

IVLong-term or often short-distance driving.

The above four points of the vehicle that burns engine oil must be occupied by one or all four points.

How the piston rings are stuck.

The principle of piston ring stagnation should start from the oil circuit, the oil bearing temperature is 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil at a temperature of 120 degrees or higher for a long time, so that the oil will be exhausted in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time. It becomes a liter of engine oil for 1000 kilometers or even hundreds of kilometers. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

The solution to burning the oil.

In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.

Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of the operation of the auto repair shop, and the owner can operate it himself without removing a screw, and the piston ring is repaired and released during driving, and the effect is remarkable.

Why is Nissan Liwei car engine oil always young, why Nissan Hall knows Liwei ( check transaction price |From the perspective of various oil burning situations, the German Marty can be roughly divided into three types: cold car oil, rapid acceleration of Yufuhong oil, and oil burning at any time. The method of judging is as follows:

1。Burning oil in a cold car: The burning of oil when a cold car starts.

Method: Park for one night and observe the exhaust gases when you land for the first time in the morning. If the exhaust is thick blue smoke, it means that the vehicle has burned oil.

If the blue smoke disappears after the car is hot, this type of engine oil is a cold car oil. 2.Accelerated oil burning:

Oil burning occurs when the speed rises rapidly. Method: After the car is warmed up, no matter during rapid acceleration or idling, as long as the speed of the car rises rapidly, blue smoke will be emitted from the exhaust pipe, indicating that the car is burning engine oil.

3.Burn oil at any time: No matter what the situation, the phenomenon of burning oil will occur when the vehicle starts.

Method: Once activated, you can see the blue smoke. At this time, the engine burns oil quite seriously, and there may even be potential safety hazards.

In addition, you can judge by fuel consumption per thousand kilometers. The national recommended standard is fuel consumption of more than 1,000 kilometers. Hope it helps.
