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.
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.
Principle and disadvantages of piston ring released by heating liquid with heating rod The heating rod will explode without liquid, which is easy to hurt workers. When heating, remove the oil pan, turn the crankshaft by hand and loosen the piston ring. If the operation time exceeds 10 hour, people can't operate all the time, which will delay the opportunity cost for operators to repair other vehicles. So in actual operation, the work of this spindle is always very small. 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.
So how exactly is it corroded? Let's explain it in detail with case analysis.
The purpose of piston ring release by heating rod is to corrode carbon deposit by heating repair solution continuously, so as to release piston ring, just like engine maintenance. In order to solve the piston ring release, all possible new problems are deliberately ignored to achieve a goal.
Risks and disadvantages of heating 1. The heating temperature of the heating rod is as high as 100- 160 degrees. You need to know how strong this temperature is. Ordinary water vapor can disappear instantly at this temperature. Therefore, construction personnel should constantly ensure the stock of liquid medicine in the cylinder. If they are not careful, the heating rod will burst and hurt the staff. So this operation is still necessary.
2. Because manual reels are needed, no repair shop can operate 100% perfectly, and only half of them can be operated at most, so the integrity of the construction can not meet the requirements.
Heating time: the heating rod will work continuously for more than 10 hour, and the high temperature will continue at about 150 degrees. Do you know what will happen? The metal cylinder will be corroded. See the corroded cylinder wall below.
The corroded cylinder wall is white and gray with black stripes. The third picture shows a normal cylindrical wall.
The wall of another corroded cylinder has small black spots. After the original protective layer of the cylinder wall metal is completely burned, the cylinder body is gray. At this time, the top of the piston will also be corroded and pitted, and the piston will be replaced seriously.
This is the normal color of the cylinder wall, so the normal color of the cylinder wall is reddish brown, because it is in contact with the mixture of engine oil and combustion, but this picture belongs to another car, and some traces of carbon deposit are not serious, because the oil circuit has not been cleaned for a long time.
Hazards after heating During continuous heating at 150℃ for more than 65,438 hours, the cylinder block is likely to deform, especially for all-aluminum engines. When the cylinder block is corroded and deformed seriously, there is no way to solve the problem of oil repair. The only way is to overhaul the engine and make a new cylinder block to run in, which will cause heavy losses.
Present situation of oil heating repair There are many risks and hazards in oil heating repair. Why are there so many repair shops still in use? If it really exists, is it reasonable?
In fact, there is a problem of resource allocation interests in economics. A large number of repair shops have purchased a large number of heating and maintenance oil and raw materials for heating rods (hundreds of machines) when they are not exposed to more convenient, safer and more scientific oil maintenance technology. At this time, someone must pay the bill and digest these stocks before they can buy the latest technology products again. Often the technical products of black technology are the slowest to be accepted, but once accepted, they are also the fastest to be used.
So existence is reasonable, which is not appropriate in economics.
How to correctly solve the problem of burning engine oil In solving the problem of burning engine oil, just remember one sentence, don't overhaul the engine unless the cylinder is seriously pulled. Because most of the problems of burning oil come from the piston ring sticking, we can solve most of the problems of burning oil as long as we are familiar with how to solve a high probability problem, and leave the small probability things to the big ones with special research spirit to study. The national policy is to let some people get rich first. More importantly, I think this small series can solve most problems, which is successful.
The long-term uncleanness of the vehicle oil circuit leads to the aggravation of the oil circuit problem, which leads to excessive carbon deposition during combustion, and the piston ring is stuck due to excessive carbon deposition. It is said that 10 thousand roads and 1000 roads are still the problem of oil. With the improvement of engine technology, the carbon deposition caused by fuel mismatch exceeds the standard, so the oil circuit is fundamental. It is the most scientific method to solve the problem from the root and realize the two-way technical path of treatment and prevention. See below.
After the piston is completely covered with carbon deposits, the gap between the cylinder wall and the piston is also blocked, so too much carbon deposits can easily strain the cylinder wall. At the same time, this phenomenon will lead to the problem of burning oil because the piston ring is not scraped cleanly, and the engine oil will participate in the combustion, resulting in greater carbon deposition and vicious continuous circulation.
At present, the leading oil bottom cleaning technology is to release the piston ring to realize oil burning repair. This technology is mainly developed by Dalian Yichenghou University of Chemical Technology and Siyoupu. As long as the fuel tank is added, the piston ring can be automatically released by the engine after several times of driving. 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. You can clean the oil circuit, remove the carbon deposit from the fuel injector and release the piston ring, as shown in the following figure. The disadvantage is that you drive too much.
After the carbon deposit in the piston is cleaned, it continuously seeps into the gas ring and enters the oil ring, releasing the carbon deposit in the oil ring, thus achieving the purpose of repairing the burning oil.
2. Will it be corrosive
Absolutely not, because it can be burned into the combustion chamber normally when added to the fuel tank, so there will be no corrosion. The toilet cleaning forest can also clean up the carbon deposit, but it cannot be added to the fuel tank. Try the fuel tank, the engine won't catch fire! More PICC testing underwriting, large-scale institutions certification blessing.
Finally, there are still many aspects to be communicated about the repair of engine oil. We only discuss the above issues today, and the space is limited. I hope you can leave a message. How do you understand the problem of engine oil and how to repair it? Usually, the oil circuit should be cleaned frequently or regularly. As long as the oil circuit is kept relatively clean and the carbon deposit is not generated so quickly, the engine oil will not burn prematurely, or the engine oil will not burn for 20W km. PNF or spinning dope cleaner can be used, which is more suitable for household fuel cleaning.
