03 How to solve the problem of burning engine oil in Maxima

Reasons why Maxima burns engine oil and how to prevent it.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the following reasons will aggravate the oil consumption and cause the burning of engine oil, so that the vehicle appears:

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.

Burning engine oil means that the engine oil enters the combustion chamber of the engine and participates in the combustion along with the mixture. The phenomenon of "burning engine oil" in the vehicle will damage the vehicle's oxygen sensor too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, increased fuel consumption, and excessive exhaust emissions.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel in the combustion process is indispensable to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston wall clearance, etc., all have a direct or indirect relationship with the formation of carbon deposits, considering the relationship between domestic oil products, it is necessary to use high-quality engine oil and (PNF) fuel additives to achieve, which is also the key to achieve no dismantling and repair to solve the problem of burning engine oil.

Therefore, the problem of burning engine oil that you are talking about generally has two parts: one part is the cylinder block, and the other part is the cylinder head.

There are several situations of cylinder burning oil: one is excessive wear of the cylinder barrel, and the other is excessive piston wear or piston ring failure. When the cylinder barrel is worn too much, forming a "platform" at the dead center of the piston, and the cylinder barrel is worn unevenly, and the driving cone or elliptical, the oil brought up by the piston ring will accumulate and participate in combustion; When the piston is worn too much or the piston ring loses its elasticity after long-term use, the sealing is not tight, and too much oil is brought into the combustion chamber to participate in the combustion, which will also form oil burning.

The cylinder head burns oil because the valve guide is worn and the gap is formed, which causes the oil to leak into the combustion chamber or the valve oil seal is aging and the sealing degree is reduced, causing the oil to flow into the combustion chamber along the valve and participate in combustion.

When the engine oil is slight, you can roughly judge the fault location by observing the exhaust: if the engine oil is burned when the car is cool, it is most likely the valve oil seal, and if the car is hot and the oil is burned, it is most likely the piston or piston ring. When the oil is burned severely, it is difficult to judge whether the cylinder block or the cylinder head burns the oil, the engine must be disassembled for inspection, the piston must be removed from the cylinder barrel, and the roundness and taper of the cylinder barrel must be measured with an inner diameter micrometer to determine the specific cause of failure.

The specific repair ** is determined according to the damaged parts and the degree of repair, and the labor hours of each store are also different.

Reasons for burning engine oil:

1.Do not do effective cleaning oil circuit for a long time, 2The antifreeze is not replaced in time, 3The oil life cycle is too long.

4.Long-term short-distance driving. The car that burns engine oil must occupy one or all four points. Please be seated.

Most car oil burning 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 treat the symptoms rather than the root cause. When the oil enters the combustion chamber to participate in combustion, more carbon deposits will be formed, which in turn 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.

Don't worry about burning engine oil, prescribe the right medicine, as long as the carbon deposition problem of the piston snap ring is solved, there is no need for overhaul, and the problem of burning engine oil can be directly repaired. Before burning engine oil, through many understandings, the vehicle was completely solved by using the method of dismantling and non-destructive repair of burning engine oil by Siyoupu.

The problem of adding one liter of engine oil for 1,000 kilometers, after fixing, there is no need to add oil for 5,000 kilometers. At the same time, it can clean the carbon deposits and colloidal impurities in the oil circuit, and the plugging of the fuel injector and the carbon deposits in the combustion chamber can be cleaned at one time.

As long as you use the general burning oil repair agent for 4 times in a row and drive more, you can clean the carbon deposits on the top of the piston and release the piston ring.

Be sure to clean the oil circuit, with effective cleaning, and must be suitable for the domestic oil circuit cleaning, do not use indiscriminately, with detergent and with effective cleaning are two different things.

Find out the cause and solution of burning engine oil in the car.

The common fault points of oil burning fault are:

It could be the gasket between the engine block and the engine head, this part is called the "gasket". The cylinder gasket is damaged or aged, the sealing effect is not good, and the engine celebration oil flows into the combustion chamber and burns.

After inspection, it is determined that the cylinder gasket is damaged, and replacing the cylinder gasket can solve the fault of burning the engine oil.

2.It may be that the valve oil seal inside the cylinder head is aged or damaged, causing the oil to flow into the combustion chamber when the valve is opened. There is a fault phenomenon of burning engine oil.

After inspection, it is determined that the valve oil seal is aging or damaged, and replacing the valve oil seal can solve the fault phenomenon of burning the engine oil lamp.

3.It is a crack in the oil duct of the cylinder head and the cylinder block, which causes the oil to flow into the combustion and combustion, and the fault phenomenon of burning the engine oil appears.

After checking the late slag, it is determined that the cylinder block or cylinder head is cracked, and the cylinder head or cylinder block is replaced to solve the fault of burning the engine oil.

The 06 Mazda6 Flagship is oil-burning. It is inevitable that the oil will be evaporated, and it is more obvious when running at high speed, when the oil is added too much, the crankcase pores will overflow with organic oil, and if the oil is burned, the exhaust will emit blue smoke, and the cylinder will be worn, the valve oil seal will be aged, and the cylinder gasket will be damaged. The only way to solve this problem once and for all is to replace the piston rings.

The solution to burning engine oil in automobilesChange the engine oil, the main reason for burning the engine oil is the problem of the car oil, so when adding the engine oil to the car, we must do a good job of control, the quality of the car oil is not good, it is easy to produce problems such as car carbon deposition, oil seal aging, etc., through the way of replacing the car oil, you can avoid the phenomenon of burning the engine oil from the root. For such serious problems, it can be solved by overhauling the automobile engine, but after the engine overhaul, there will be some ***, resulting in a reduction in the service life of the engine.

In the case you said, if the space between the valve and the valve guide is not large, you can clean the carbon deposits on the valve; If the amount of space is large, not only should the valve be replaced, but also the valve guide should be checked to see if it has been worn, and if the wear is severe, it should be replaced together. If you don't change the valve, you don't need to grind the valve. If the cylinder head is removed, the cylinder gasket must be replaced, and if the antifreeze has been used for about 1 1/2 to 2 years, it is best to replace it together.

As for the problem of measuring cylinder pressure, if the engine burns oil, there will definitely be carbon deposits inside the combustion chamber, and if there is organic carbon, the cylinder pressure will definitely change, and it should be measurable. In fact, the easiest way to check the burning engine oil is to remove the spark plug and check whether there is oil stain or thick black carbon deposit on the spark plug, if there is any 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.

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.), it should be checked at the maintenance station as soon as possible and repaired as soon as possible.

First of all, it's not a battery problem. The symptoms of starting difficulty caused by the battery are, it is difficult to cool the car, and it is easy to warm the car.

In addition, from the situation you described, it is more likely that the friction surface of the engine is worn, such as cylinder liners and piston rings, resulting in increased gaps, and the oil cannot be sealed, resulting in gas blowing in the combustion chamber and difficulty in starting. It is estimated that your car has a high fuel consumption and is also low on power. When the oil temperature is low and the viscosity is relatively high, the sealing will be better, so the difficulty of starting will be smaller.

It is recommended that you go to overhaul the engine as soon as possible.

If the overhaul is not standardized, and the engine needs to be overhauled again, you can go to the repair shop where you overhaul it for repair.

The overhaul was not repaired. Positive. Then go to the maintenance unit and ask for a new repair.

Consume so much oil and don't emit blue smoke, is it leaking, otherwise it doesn't make sense! Pay attention to the location of the parking spot for organic oil leaking on the ground! The car can impress, but it can't, it shouldn't be a battery problem!

First of all, it is definitely not a battery problem, the hot car can not be sent out may be a problem with the ignition coil, if the engine oil is burned, it has been overhauled, the valve oil seal has been replaced, whether the piston ring is damaged during the assembly process, or the piston ring buckle is displaced, it is possible.

Don't call it a thousand miles, a mile of donkey is more suitable.

It's not a battery problem, the hot car can't be sent out, it may be that there is a problem with the ignition coil to check.
