Causes of engine oil burning and how to eliminate them

1. The oil enters the combustion chamber from the cylinder wall.

The main reasons why the oil enters the combustion chamber from the cylinder wall are: the piston ring is installed to produce the effect of pump oil; The piston rings are badly worn, the opening clearance is too large or the roundness is reduced; The piston ring breaks off and gets stuck in the ring groove; The piston ring tension is too small; Crankcase vent ducts are clogged, check valves are stuck or there is too much carbon deposit. In addition, if the boring tool feed is large, the knife lines are deep, or the cylinder barrel material is unevenly soft and hard, different shapes of concave and convex surfaces will be formed on the inner surface of the cylinder wall, which will increase the amount of oil penetration in the combustion chamber, thereby causing the engine to burn oil.

To judge whether the piston ring pumps oil upward, the following methods can be taken: remove the cylinder head, use a starter or manually rotate the crankshaft to make the piston run up and down. If there are more oil stains on the cylinder wall, wipe it clean and repeat the test several times.

If there are still more traces of oil on the cylinder wall, it means that the piston ring is pumping oil upward.

Therefore, when installing the piston ring, the inner chamfer should be upwards and the outer chamfer downward. When replacing the new piston ring, it is also necessary to ensure that its opening clearance, side clearance and back clearance should meet the assembly size requirements of the piston ring of the type of machine, and each ring mouth should be evenly distributed between 360°.

If the inner surface of the cylinder wall is uneven, only the better quality cylinder liner can be replaced, and the inner surface of the cylinder wall can be reprocessed according to the required size.

2. The oil escapes into the combustion chamber from the valve guide.

The main reasons for oil to enter the combustion chamber from the valve guide are: damage and hardening of the valve oil seal; The catheter is severely worn, resulting in a large amount of valve stem swing and a decrease in the sealing performance of the valve seal.

There is a simple way to replace the valve oil seal of the gasoline engine, as follows: first, remove the spark plug, turn the crankshaft to shake the piston to the dead center; Secondly, a curved iron rod is inserted into the combustion chamber from the screw hole where the spark plug is installed, and the valve head is pressed against it; Finally, open the valve chamber cover, remove the valve spring, and replace it with a new valve seal. In this way, it is quick and easy to get the valve stem falling into the cylinder barrel, and there is no need to remove the cylinder head, replace the head gasket and waste antifreeze.

3. The oil is sucked into the combustion chamber from the crankcase.

The main reasons why oil is drawn into the combustion chamber from the crankcase are that the air filter is heavily clogged with sludge and the end cap of the oil line for filling the oil is missing. In this case, a large amount of air enters the combustion chamber from the oil pipe mouth of the processing machine - crankcase - crankcase exhaust pipe - air intake pipe without passing through the air filter.

The inner diameter of the crankcase exhaust gas pipe is small, and after the throttle valve is opened, a strong air flow will be formed in the crankcase exhaust gas pipe. This air flow draws the splashed oil from the intake pipe into the combustion chamber, and the oil burns together with the mixture, resulting in oil burning.

In the event of such a failure, the air filter element should be replaced and the nozzle cap for filling the oil should be prepared.

The treatment methods are; 1. The owner should replace the valve oil seal of the vehicle in time to ensure the valve tightness. The valve oil seal will be aged and seriously worn out after long-term use, and the vehicle with a longer service life or more kilometers is more likely to burn engine oil; 2. The oil with appropriate viscosity can increase the tightness between the engine piston and the cylinder wall, and the use of this oil can alleviate the phenomenon of oil burning, but it cannot be completely eliminated;

3. Replace the piston ring of the car, and regularly clean the carbon of the surface area of the piston ring;

4. Check the oil ruler frequently, and the scale of the oil ruler is generally added to the best between 4 and 5, that is, eighty percent of the position, too much or too little. In addition, regularly replace the oil and oil filter spare parts according to the requirements of the product manual; 5. Choose high-end or high-quality engine oil, especially for engines with turbochargers, because its higher operating temperature and higher oil requirements. Choose an oil with a low volatility rate, as oil volatilization can also cause the car to burn oil.

In addition, choosing a fully synthetic engine oil can greatly reduce the phenomenon of burning engine oil;

6. Develop good driving habits, especially for new cars during the run-in period, the speed should not exceed 90 kilometers per hour, and the engine speed should not exceed three-quarters of the maximum speed.

Through the above methods can solve the phenomenon of engine oil burning, the owner should avoid the above wrong methods in daily maintenance, and prolong the service life of the engine.

Hello! The reasons for engine oil burning are generally as follows: First, after a long period of use, the cylinder, piston and piston ring wear excessively, and the gap becomes larger, resulting in the oil from the gap into the combustion chamber combustion, at this time, it can be solved by overhauling the engine, replacing the piston and piston ring, and replacing the cylinder liner cylinder.

The second is that the valve oil seal is aging, and it can be replaced. The third is other reasons, such as burning oil caused by damage to the oil seal in the turbocharger. Thank you!

Methods for dealing with burning engine oil in automobiles:

1. Change the oil and oil filter: check the oil scale frequently, and change the oil and oil filter regularly.

2. Repair shop maintenance: Once the oil consumption is found to be abnormal, you need to go to the repair shop for maintenance.

If the oil burning is not serious, you can change the oil with a higher viscosity.

The oil burned was serious, and there was no other way to overhaul the engine.

Don't do it, that thing hurts the engine even more.

Engine oil burning treatment method: use fuel additives. There are certain reasons for the formation of carbon deposits in some engine oil, although carbon deposits in the engine are inevitable, but we can also cooperate with some clean fuel additives to solve the remedy.

If the engine burns oil, if it is not serious, you can supplement the oil, use a higher viscosity oil, there is a certain repair effect, or the engine must be overhauled, replace the piston ring, if the cylinder liner is seriously worn, but also replace the cylinder liner.

The engine is supposed to consume a lot of oil when it starts, and there is no way to deal with this, because as long as your car wants to move, it must need energy, and if you think the oil is more expensive, then you can change to an electric car.

How to deal with the burning oil of Huadu engine? How to deal with engine oil burning? There are engines that burn oil, and there are diesel-burning engines that burn oil, and there are diesel engines.

If you buy engine oil, if you buy oil burner, then if you buy oil, then only if you buy oil, then you can only use engine oil, if you buy oil, then you can only use oil.

The car that burns the engine oil is seriously depreciated after the engine is overhauled, or is it sold directly.

The most fundamental way to solve the problem of car oil burning is to disassemble and repair and replace the worn parts, so that although the one-time investment is larger, the durability and reliability and the recovery of vehicle power are guaranteed, as for the use of additives, it is only a temporary solution.

The hazards of burning engine oil in automobiles and their solutions are as follows:

1. Slight burning: fuel consumption, insufficient power, easy to produce carbon deposits, after carbon deposits, it will be difficult to get on the car, and the engine will shake.

2. Severe burning: The oil consumption is very large, and the engine is very worn. When the oil burns out, the engine is about to be overhauled.

3. Identification and inspection: the concentration of blue smoke. Pull out the oil ruler often to see how fast the oil is consumed.

Solution: 1. If the old vehicle burns oil, you can appropriately choose to add oil with relatively high viscosity to the engine to increase the tightness between the engine piston and cylinder wall. Of course, the ultimate way to completely solve the problem of burning engine oil is to overhaul the vehicle more thoroughly in order to fundamentally solve the problem.

2. If you find that the vehicle has signs of burning engine oil, you should always check the scale of the engine oil, regularly replace the oil and oil filter according to the requirements of the product instruction manual, and replace the spare parts of the oil filter.

Improve the viscosity of the oil, if the viscosity of the oil is improved, you can add anti-wear agent separately, if there is still no improvement, you can only open the cylinder and overhaul the engine.

Burn the engine oil first to determine the cause, and then think about how to solve it.

1. Due to the aging of the valve oil seal and the lack of tight sealing caused by the loss of elasticity of the rubber, the engine oil penetrates into the combustion chamber for combustion, thus being consumed. The phenomenon is that the first motor in the morning hits the car, there is a puff of blue smoke, and the car disappears quickly after the car is hot. Generally, it is caused by the high water temperature or the expiration of the service life, and the valve oil seal is aging and losing its elasticity.

2. Due to the wear of the cylinder barrel or the insufficient tension of the piston ring and the counterpart of the piston ring, the phenomenon of blue smoke comes out when the cold car or the hot car is above 3000 rpm, and the amount of blue smoke depends on the degree of wear.

3. If there is a turbocharger, it is not excluded that there is a problem with the turbocharger 4. Specific judgment: Usually the cumulative driving of the model is 5000km, and the oil consumption is less than 1 liter, we basically think that there is no need to repair it (except for new cars and German cars), and we regard it as burning engine oil if it exceeds 1L, and it is accompanied by the phenomenon of oil consumption, exhaust gas exceeding the standard, and power decline. It is advisable to inspect and repair, not necessarily overhaul, if the wear of the cylinder liner is not serious, only replace the piston rings and valve seals and valve guides.

This one definitely needs to be overhauled.

Otherwise, what do you think?

After all, this is not what you want.

Need to see for yourself.

There are four common reasons for burning engine oil.

1.If you don't clean the oil circuit for a long time or don't do effective oil circuit cleaning, detergents are used at will, and using detergents and effective detergents are two different things;

2.The antifreeze replacement cycle is too long or not changed at all;

3.The oil change interval is too long;

4.Long-term or often short-distance driving.

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

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age under the high temperature state of the long banquet detection time, resulting in the thinning of the oil film, which 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 is indispensable in the combustion process to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston cylinder wall clearance, etc., all of which are directly or indirectly related to the formation of carbon deposits, so keeping the fuel circuit clean is of great help to prevent the burning of engine oil.

3. With the help of external forces

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 solving the problem of burning engine oil without dismantling and repair.

The main reason for burning engine oilThere is a problem with the fittings, the wastegas valve, the valve seal, the cylinder is pulled in the cylinder, and the cylinder pressure is insufficient.

If the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil life cycle is too long, the piston ring is stuck, and the more common situation is that the piston ring is stuck.

What is piston ring seizureStagnation starts from the oil circuit, the oil withstand the temperature at 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 fail 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, and a cylinder stuck is 5000 kilometers of a liter of oil, at this time, the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinder wheels are stuck, and it will become a liter of oil for 1000 kilometers or even hundreds of kilometers.

SolutionAt present, there are two methods on the market that can be solved by Bijing, one is overhaul, and the second is PNF repair agent. In the case of overhaul, the cost is very high, the vehicle depreciates quickly, and the later run-in is also very troublesome. I've seen riders repair it with PNF repair agent before, you can refer to it.

Not a major overhaul to solve the problem of burning engine oil.

All kinds of models repair the record of burning engine oil.

Engine oil burning is a very serious problem and can even lead to engine scrap. Then your car will be useless, and you must know the reason for burning the engine oil in order to prescribe the right medicine. But whether it's a low-end car or a high-end car, it will burn the engine oil, but you can also take some precautions.

1. The reason why the engine burns oil.

1.Normal wear and tear.

Normal wear and tear is the normal wear and tear of a vehicle after a certain kilometer has been driven. When the general vehicle travels about 200,000 kilometers, different cars, different people driving, and different areas will have a great impact on the service life of the engine, so there will be some problems with the engine to a certain extent. For vehicles that exceed a certain service life and kilometers of normal wear and tear, repairs should be carried out.

2.Abnormal wear and tear.

The main cause of abnormal wear is early wear caused by product quality and improper use. If there is a phenomenon of Xiaoshu burning engine oil during the warranty period, we must contact the 4S shop in time to repair or replace the engine.

There are many reasons for early engine wear. It is important to know that the oil and filter are not changed regularly, and substandard oil or oil-free operation will cause engine overload, low oil pressure, insufficient oil pump power, and oil.

Second, the engine burning oil protection method.

There are many reasons why an engine burns oil, but it is not impossible to prevent it, such as using high-quality engine oil (gasoline and oil). Of course, the ultimate solution to burning engine oil is to overhaul the vehicle thoroughly, solve the problem fundamentally, check the oil scale frequently, and change the oil and oil filter regularly according to the requirements of the instruction manual to protect the engine and prolong the service life.
