Oil is known as the engine running blood, on the one hand to help clean, lubricate, seal the engine, on the other hand by the engine design flaws, leading to the engine oil into the cylinder combustion, the formation of the so-called burning oil".
[reason] of engine burning oil
1 valve oil seal leakage of oil, the reason is that the quality of the valve seal is not good, or the engine temperature is high, or the exhaust valve to guide the impact of the exhaust valve oil seal.
2, crankshaft ventilation mechanism can not be filtered out of the oil, leading to oil is sucked into the inlet, this situation can only improve the engine oil filtering mechanism, to eliminate failures or improve efficiency.
3, Hendin said leaking oil from the piston hub, it showed that only the exhaust side has solar term door carbon deposition, but the greatest harm, the main reason is the quality of piston and piston rings or inferior process due to lack of accuracy, but this is just like the table, because now the engine materials we are just about the same, so in the same the material under the same displacement (with 1.6L engine as an example): some engine uses a short stroke piston, large bore, piston ring under such oil and gas energy area is much larger than the small bore long stroke piston ring, so bear oil and gas energy area is small, so in the same displacement, piston ring tension push on the piston is different, push and pull the greater damage to the piston ring piston is greater. In the turbine, the piston ring to bear the larger gas oil energy, piston rings to the piston damage is greater, more heavy the extent of burning oil.
[burning oil hazards]
The harm of burning oil is not only consume more oil, because of excessive oil to participate in combustion, the combustion chamber is not completely burned, easy to form a large number of carbon accumulation, so that excessive emissions, polluting environment. In addition, the engine power, noise, fuel consumption and other aspects will be greatly affected. Hengding hub said in driving the process, there will be idle instability, accelerate fatigue and other symptoms, but also accelerate the damage of oxygen sensor, causing a blockage of the three-way catalytic converter. Because of the burning oil lead to the excessive carbon, for a long time, easily lead to stuck piston rings, piston ring loses the role of the oil scraper, increased the oil into the combustion chamber of probability. Also stuck piston rings may also lead to increased wear of the piston and the cylinder wall, which resulted in a lax cylinder jump gas piston seal, and caught in a vicious cycle, serious even cylinder engine scrap and other serious consequences.
How to prevent burning oil
1, to avoid engine burning oil in general is the use of qualified, suitable oil, and regular replacement. It should be noted that the design concept of various countries of the car engine is different, so for different countries of the models, the use of their vehicles for the oil model.
2, travel more than one hundred thousand kilometers of the old car, you need to choose a slightly higher oil viscosity to increase the sealing performance of the piston and cylinder wall between.
3, to avoid the frequent urgent acceleration and high speed driving. Long time high speed travel can make lubricant oil film fracture, can lead to the engine piston lubrication, dry mill, resulting in wear and burn oil.
4, some burn oil is designed on the cause, obviously the vehicle without any trouble, the consumption of oil is particularly large. Europe and the United States Department of engine generally in the seal and precision of the engine, so the engine (such as Volkswagen series engine), the engine (such as Volkswagen EA888 series engine), usually to pay attention to check their work, regularly check the amount of oil consumption is normal, etc..
How to deal with oil burning fault
The use of additives, through the engine at work inside the high temperature, high pressure metal forging in the friction surface, the formation of a new friction surface, increase the original size of the workpiece, to enhance the seal, the role of the protection of the original friction surface. Hengding hub said the use of additives although can alleviate the phenomenon of burning oil in a certain extent, but the additives are not completely resolved oil burning issues. If the engine oil phenomenon is too serious, it is necessary to disassemble the engine repair, the use of a simple additive effect is very small.
