Solution of engine oil combustion

What is burning engine oil? In 2008, the state had clear regulations on automobile engine oil. It is understood that the current standard of German automobile manufacturers is to consume oil ≤0.7 liters per thousand kilometers. China should also formulate this standard, that is, the fuel consumption per thousand kilometers should be ≤0.3 liters. That's 3000 kilometers. A liter of oil is burning oil. It can be seen that insufficient engine oil is normal consumption. This is what we call burning oil.

But the standard is the standard, which has many disadvantages in the actual car use. For example, some car manufacturers promise that the gearbox oil will not be changed for life, but it must be changed for tens of thousands of kilometers in domestic vehicles.

Harm of burning engine oil So what are the hazards of engine oil consumption to vehicles? Our topic today is mainly not here. We just need to remember that the participation of motor oil in combustion will lead to the participation of motor oil in the mixed gas, which will lead to greater carbon deposition in the combustion chamber, and the burning motor oil will be discharged to the ternary, which will lead to ternary pollution and serious blockage of the ternary for a long time. If this problem continues to develop, more oil will burn. Therefore, reaching the standard of not burning engine oil does not mean that a small amount of engine oil consumption has no effect on the vehicle.

Do you have to overhaul the engine to burn oil? Just remember not to pull the cylinder to repair the engine. In addition to the assembly risk, the overhaul also has a huge depreciation of the residual value of the vehicle.

Back to burning engine oil to repair the engine, in the eyes of ordinary people, burning engine oil should overhaul the engine, but many drivers say: although burning engine oil, the engine is still powerful. In fact, burning engine oil and insufficient power are not exactly the same thing, that is to say, burning engine oil is not the only standard for engine overhaul. For engine overhaul, it has a considerable correlation with the level of technicians and the quality of accessories. However, even if the technology is exquisite and the accessories are authentic, it will do harm to the engine. After all, as a very sophisticated and core auto parts, there are some hidden dangers for future use. Engine oil combustion is a comprehensive problem, so it is not necessary to burn engine oil in overhaul. Under modern technology, engine oil combustion is mostly caused by the problems of high compression ratio and fuel matching, which can also be understood as the unstable and long-term accumulation of combustion quality caused by long-term unclean fuel quality or fuel circuit.

Today, we will discuss several links that cause engine oil to burn. In fact, it is four links. For most cars, as can be seen from the following, almost all of them are inseparable from one factor:

Probability and cost ranking of engine oil consumption caused by various components

Attachment (according to the probability of occurrence, the probability of occurrence per 100 vehicles, in the following order)

1. The piston ring was stuck, resulting in the oil remaining on the cylinder wall, and 97% of it participated in the combustion.

2. Waste gas valve fittings are aged by 20%

3. Oil seal aging 10%

4. Turbine 7%

5.3% cylinder pulling?

According to the regular maintenance fee.

1. Maintenance of piston ring and cylinder.

2. Valve oil seal

3. Turbine maintenance

4. Replacement of waste gas valve

As can be seen from the above, piston ring sticking is the biggest problem probability and the highest maintenance cost. Therefore, except for special models, most vehicles burn oil and piston rings. Therefore, according to the principle of high probability research category, the technology of repairing oil without overhaul at present is all around piston ring.

Discuss and compare the advantages and disadvantages of various technologies for repairing fuel release piston rings. Check the engine.

Assembly risk, multi-person operation, inconsistent technology and large depreciation of vehicle residual value. And it takes a week, and there is an extra charge for using other means of transportation.

2. The heating rod heats the liquid medicine and releases the piston ring.

The heating rod will burst without liquid medicine, which is easy to hurt the staff. When heating, remove the oil pan, turn the crankshaft by hand, and loosen the piston ring through the continuous operation of the crankshaft. The operation time exceeds 10 hour, which leads to the personnel being unable to work all the time, and greatly delays the opportunity cost for the operators to maintain other vehicles. Therefore, in actual operation, the work of the spindle is only a small part, which can not guarantee the real demand of the spindle. Because the corrosive liquid medicine is used, after a period of time, many pits, corrosion and burn marks will be found on the top of the piston, and the piston should be replaced seriously.

3. Add the release mode of engine oil

The principle of adding oil is to release the piston ring through corrosive liquid medicine. The oil should be changed frequently to prevent serious deterioration of the oil, which has no protective effect and causes cylinder pulling problems. The oil filter element should also be changed frequently, and the additional cost is high. After the repair, the liquid medicine in the oil pan can't be discharged clean, because it will pollute the fresh engine oil and lead to the rapid deterioration of the engine oil. Because it is used in engine oil, it is impossible to clean the burning engine oil, such as carbon deposition on the top of the piston and the oil circuit of the fuel nozzle, which can cure the symptoms rather than the root cause. Because the oil circuit problem is not completely solved, even if the piston ring is released soon, it will be stuck.

4. Play the infusion bag or infusion bottle release mode.

The principle of this mode is that the electronic bottle in the air inlet is continuously and slowly input and sprayed to the piston top, and the carbon deposited on the piston top gradually penetrates into the piston ring at the damaged point. The time is one week, and the vehicle runs at idle speed for several hours every day. Idling itself is the fastest way to produce carbon deposits, and long-term idling has a great influence on the car. A week's time has also caused the inability to use vehicles and the cost of using other means of transportation.

5. Oil bottom cleaning technology releases piston ring.

Because the piston ring is stuck due to carbon deposition, because the oil circuit is unclean and deteriorated for a long time, or the fuel is not good, the combustion is not good, the carbon deposition exceeds the standard, the engine technology is improved, and the carbon deposition exceeds the standard, so the oil circuit is fundamental, and it is the most scientific method to solve the problem from the root and realize the technical path of prevention and control.

At present, this technology is mainly developed by Dalian University of Technology, Dalian Yicheng Aftercar Chemistry and Siyoupu Joint Laboratory. As long as the fuel tank is added and opened a few more times, the piston ring can be automatically released by the engine spindle. It contains all the functions of ordinary fuel additives, and can release piston rings at the same time, which really solves the problem of burning engine oil from the bottom technical logic. The disadvantage is that you drive too much.

After understanding the advantages and disadvantages of various technologies, let's take a look at common fuel additives and briefly understand why carbon deposition on pistons can't solve the problem of burning engine oil. Technical logic: ordinary fuel additives are only used to clean up carbon deposits to prevent engine oil burning, but when engine oil burning occurs and the problem escalates, it is impossible to solve the engine oil burning problem with defensive strategies. It's like drinking Radix Isatidis to prevent colds, but taking medicine after catching a cold. Only when the cold is cured can it be prevented with Radix Isatidis. That's the truth.

Finally, for cars that have not burned engine oil, it is best to use effective additives suitable for domestic oil products and clean and maintain the oil circuit regularly or frequently. Domestic fuel is completely different from foreign fuel, and there are still some deviations in maintaining domestic oil circuits with foreign fuel. Of course, foreign additives are suitable for foreign fuels. If your car can always use foreign fuel, it is entirely possible to use additives from exporting countries. At present, the cleaning agent that is more suitable for domestic fuel oil is Sioupu stock solution, which is widely used. Ocean, aviation and automobiles.
