Renault 1 2t engine burns oil

It is inevitable that the oil that plays a lubricating role between the piston and the cylinder wall in the engine will participate in the combustion, as long as it does not exceed one liter within 5,000 kilometers, it is normal oil consumption, and vice versa. The lack of engine oil will cause the engine to heat up badly, the car will shake abnormally, the water temperature will be high, the valve will sound, and in serious cases, it will even strain the cylinder wall or burst the cylinder.

Burning engine oil is basically caused by piston ring stagnation. As long as there is no serious strain on the cylinder wall, it does not need to be overhauled. Changing the maintenance of high-viscosity engine oil is only an expedient measure to treat the symptoms rather than the root cause, and it will do more harm than good.

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 got rid of the technical shackles of burning engine oil and having to go to the auto repair shop for overhaul, without removing a screw, repairing and releasing the piston ring stuck while driving to solve the problem of burning engine oil, and the effect is very good.

Hello! Your questions will be answered comprehensively by the little lazy pig for you, the information is not easy to find, I hope you can, thank you!

Check whether the supercharger is oiled, if it is not oiled, it may be that the piston ring is not the right angle, or the piston ring is reversed, or it is possible that the engine is not running-in after overhaul, and the piston ring is broken due to the large throttle, and the oil will also be crossed.

Hello, burning oil can only overhaul the engine, I hope it can help you, thank you for your support to the car master, I wish you a happy life [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

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 air ring of the noisy plug 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 a plan to solve the problem of burning engine oil without dismantling and repairing, which can be understood by taking a look.

The main reasons for burning engine oil 1, poor quality or viscous leakage socks grade does not meet the requirements of the engine oil tung search. A low oil quality grade can lead to increased wear, and poor engine lubrication can be caused by too low or too high oil viscosity

Generally speaking, the oil will burn the oil slightly, the valve oil seal will burn the oil when it is aging, the cylinder liner will be changed to dig wear and core, and the piston ring will burn the oil if the wear is serious.

Oil burning caused by excessive oil filling. When the high-profile oil filling exceeds the center line, due to the high oil pressure, the part of the spine machine that is lubricated by splash will be too much into the combustion chamber for combustion.

Use oils that are of poor quality or do not meet the viscosity grades. In addition, the low or high viscosity of the engine oil will cause poor engine lubrication, which will increase the wear of the piston ring and cylinder wall, and the sealing performance will decrease, resulting in the burning of engine oil.

Burning oil in a car engine may be caused by a leak in the cylinder oil seal.

First, the main reason 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.

Second, the method of preventing the burning of engine oil.

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.

Causes of organic oil in car tanks:

1) The phenomenon of punching.

2) Whether there is a problem with the radiator of the gearbox.

3) Whether there is a problem with high water temperature.

4) Flushing cylinder gasket: After the cylinder gasket is damaged, the oil channel and the waterway are connected, because the pressure of the oil is higher than the pressure of the cooling water, the oil enters the waterway and then enters the water tank. Observe that there is air flow escaping from the surface of the cooling water of the water tank.

After the shutdown, the cooling water flows into the oil duct and into the oil pan. (5) Cylinder liner cracking. Due to the high fuel pressure in the cylinder, the engine oil and diesel oil are "squeezed" into the cooling water through the cracks of the cylinder liner under the action of high pressure, and the circulation of the air mass is very violent when the surface of the cooling water is observed.

6) Faulty oil cooler. During the assembly and manufacture of the oil cooler, the cooling pipe itself has cracks, poor welding, or freeze and cracks of the cooling pipe due to the failure of the cooling water to be cleaned during winter storage, so that the oil enters the cooling water. If you observe the surface of the cooling water in the tank, it is generally calmer.

When judging the above-mentioned faults, they can be identified by observing the changes between the water tank and the cooling water. However, when observing, the pump belt should generally be removed, the pump should stop working, and the cold ground water in the water tank should be kept relatively stable. Don't rush to replace a component.

After the fault part is determined, the repair will be carried out.

Automobile water tank: 1) also known as radiator, is the main part of the automobile cooling system; The function is to dissipate heat, the cooling water absorbs heat in the water jacket, dissipates the heat after flowing to the radiator, and then returns to the water jacket to circulate to achieve temperature regulation. It is an integral part of the engine of the car.

2) It is composed of radiator core, water pipe, heat dissipation air blades, upper water tank and lower water tank. The upper water tank is on the radiator, the upper water tank is connected with the water tank under the radiator by the water pipe, the hot water flows from top to bottom to the lower water tank becomes warm water, and the heat dissipation air blades form a hole, by the suction of the fan and the relative wind speed when the car is moving forward, so that a large amount of cold air through the air hole, the heat flowing through the cooling water in the water pipe is absorbed, and then dispersed in the atmosphere.

It's the oil in the tank, not the oil.

Leaking gaskets. Hurry up and repair.

Generally, the cylinder mattress is flushed

Hello, maybe the cylinder gasket is broken.

The reasons for burning engine oil can be understood

1.Domestic oil products (including volcanic gasoline and engine oil) are prone to carbon deposits;

2.Carbon deposition causes the piston ring to jam, and the lack of oil scraping performance is lost; The oil return hole is blocked, and the oil cannot return to the crankcase normally;

3.Wear between the cylinder wall and the piston, the gap is too large.

4.Corrosion and aging of valve oil seals and crankshaft oil seals lead to oil leakage, etc.

You can place the "Matching Sun without dismantling and repairing to solve the problem of burning engine oil", and solve the problem of burning engine oil without dismantling and repairing the car.

My latitude is a bit of a burn of oil.

Cause analysis and solutions:

2. The oil pump cannot effectively suck in and pump out the oil due to dirty or viscous oil, resulting in low or no pressure oil pressure. The solution: change the oil.

3. The oil is thin or the oil is thinned due to the high temperature of the engine, which will leak from the friction gap of the engine that attacked the Luwang, resulting in low oil pressure. Solution: Change the oil or overhaul the cooling system.

4. Oil leakage of oil pipe, damage to the oil pump or excessive wear of its parts will lead to a reduction in the intake and pumping of oil, or no amount at all, resulting in low or no pressure in the oil pressure. Solution: Overhaul.

5. The gap between the crankshaft and the size of the tile exceeds the standard, resulting in oil leakage, resulting in low oil pressure. Solution: Overhaul.

6. The spring of the pressure limiting valve or pressure relief valve is too soft or the hairpin or steel ball is damaged, resulting in the disappearance or weakening of the valve function, resulting in the reduction of oil pressure and beating force. Solution: Replace and overhaul.

7. The oil pressure is low due to the failure of the oil induction plug, pressure gauge or circuit. Workaround: Replace the check.
