Audi’s new cars launched in the second half of 2015 all use the third-generation EA888 engine, which uses large wave-type piston rings and enlarges the oil pan design to extend the oil-burning mileage. But if it is not maintained properly, it will still burn oil after 100,000 kilometers. In fact, no matter what car model, the engine has a certain amount of oil consumption. It doesn't mean that it doesn't burn if you think it doesn't. It's just not obvious, but excessive consumption means burning oil. Burning oil does not require overhaul as long as the cylinder wall is not seriously strained
Burning oil is mostly caused by the piston ring being stuck by carbon deposits. Relying on adding high-viscosity engine oil to extend life is just a stop-gap measure that only cures the problem but not the root cause. Oil entering the combustion chamber and participating in combustion will form more carbon deposits, which in turn will lead to increased oil burning, forming a vicious cycle. If this continues, the cylinder wall will be strained, or even the cylinder will explode, and in the end the engine will have to be dismantled for overhaul.
Four reasons for burning engine oil
1. If you do not clean the oil circuit for a long time or do not do effective oil circuit cleaning, use detergents at will, use detergents and use effective detergents They are two different things;
2. The antifreeze replacement cycle is too long or not replaced at all;
3. The engine oil replacement cycle is too long;
4. Long-term or frequent Travel short distances.
A vehicle that burns engine oil at the above four points must occupy one or all four points.
How are piston rings stuck?
The principle of piston ring sticking starts from the oil circuit. The engine oil can withstand a temperature of 110 degrees, and the high temperature caused by the long-term uncleanness of the oil circuit , causing the engine oil to be at a temperature of 120 degrees or higher for a long time, so that the engine oil will deplete in advance. The small holes in the oil ring will be dried out, crusted and stuck in the long run. One cylinder will be stuck for 5000 kilometers per liter. Engine oil, at this time, the working conditions of other cylinder blocks will also start to be bad. Soon all four cylinder blocks will become stuck, and it will become a liter of engine oil every 1,000 kilometers or even hundreds of kilometers. Therefore, to solve the problem, we must start from the root of the oil circuit, which is the only way to remove the root.
Solutions to oil burning
In the inertial thinking of car enthusiasts, they always think that oil burning should be solved by overhaul. This will not only bear high maintenance costs, but also bear the burden of the vehicle. Unpredictable risks and depreciation losses caused by overhaul. Destroy the tightness and precision of the engine. Moreover, it is possible to burn oil again after tens of thousands of kilometers, so overhauling the engine is not sustainable.
The current disassembly-free technology is very mature and gradually accepted by the majority of car owners. In particular, Si Youpu's non-destructive repair products containing PNF patented technology have completely got rid of the technical shackles of having to go to an auto repair shop to operate. Without removing a single screw, the car owner can operate it by himself. It can repair and release stuck piston rings and burn engine oil while driving, and the effect is Significantly.
