Automobile oil burning is mainly caused by piston ring sticking, aging of valve oil seal and damage of related accessories. The oil burning of most vehicles is directly related to the oil ring of piston ring, and some other faults may occur, resulting in fuel consumption.
There are four main reasons for burning engine oil.
If you don't clean the oil circuit for a long time or if you don't clean the oil circuit effectively, using detergent at will and using effective detergent are two different things;
The replacement cycle of antifreeze is too long or not replaced at all;
The oil change cycle is too long;
Long-term or frequent short-distance driving.
One or all vehicles burning engine oil at the above four points must be accounted for.
The main reason of piston ring sticking
The principle of piston ring sticking should start from the oil circuit, and the reason of piston ring sticking is the oil circuit. The bearing temperature of the engine oil is 1 10℃. The high temperature caused by the long-term uncleanness of the oil circuit keeps the engine oil at 120℃ or higher for a long time, so that the engine oil will be exhausted ahead of schedule, and the small holes in the oil ring will be small, and the engine oil inside will be baked and crusted for a long time and stuck in the cylinder. At this time, the working conditions of other cylinders began to be bad, and soon all four cylinders were stuck, becoming 1000 km or even hundreds of km a liter of oil. Therefore, to solve the problem, we must start with the root oil circuit, which is the way to get rid of the root.
Engine oil combustion has developed rapidly. Tens of thousands of kilometers of new cars have no oil to burn. Once the engine oil is started, it will become very serious after half a year. I don't think you want to go through this process either, but there have been cases where the engine runs on oil, which has seriously burned out the oil. It is recommended to check it first, and don't worry about blindly handling engine problems. Burning engine oil will lead to jitter, weakness and high fuel consumption, all of which are caused by burning engine oil. Don't worry about dealing with small phenomena, first deal with the problem of burning engine oil on the main line.
How to solve the problem of burning oil? According to different engines, driving years and kilometers, we can comprehensively judge where to check the accessories. After troubleshooting the accessories, we finally pointed to the piston ring. Maintenance of piston ring problems at present. The premise of overhaul is that there is something wrong with the accessories. If there is nothing wrong with the accessories, there is no need to overhaul the engine.
Disadvantages of engine maintenance: multi-person operation technology is not uniform and assembly is not good. The heat and cooling values of the engine assembled at room temperature are not enough. Overhaul 65438+0-40 thousand, vehicle depreciation 30-60 thousand. Disadvantages of overhaul: Never turn on the engine unless absolutely necessary. After opening, there were traces of disassembly, and the car depreciated a lot in an instant, and the assembly result was unknown. In the process of disassembly, the humidity, constant temperature and low temperature of the air can not meet the operating environment of the dust-free workshop. There are many people in the process of assembly, and the technology is different. Moreover, the stability of a machine can not be guaranteed because of screwing the screws, and the phenomena such as car capacity, fuel consumption and jitter are often found in the later stage. Do not disassemble the engine without serious cylinder pulling. After the overhaul, it is necessary to change the whole of synthetic engine oil for two times in a row, and find out the road conditions. It is necessary to run in independently and complete the running-in in 3,000-5,000 kilometers. The cost of engine oil and gasoline is very high, and the running-in cost of ordinary cars is 2000 yuan. Moreover, it is more troublesome to call a trailer as soon as you call the police.
The problem of engine oil burning can be solved by using clean release agent of PNF technology to clean the piston ring without overhaul. Only this patented technology can completely solve the problem of oil repair.
