Listen to the engineer and say what is the matter of the oil burning
  • Automotive

The engine is the heart of a vehicle and must be taken care of. And high quality oil can not only effectively reduce engine wear and engine operation efficiency, but also save fuel consumption and prolong oil exchange cycle, and help to keep the engine clean, prolong the service life of the engine, make the engine long performance performance as new, and save the maintenance cost in the invisible. The current traffic condition is very bad, the vehicle is walking and stopping, the vehicle has just started and flameout. The temperature of the piston does not come up and the piston is not in the temperature. It is a small piston in a large cylinder, so the phenomenon of oil burning becomes common. There are three kinds of oil for automobile oil, 1. The reason is that the quality of the valve oil seal is not good, or the engine temperature is high, or the exhaust is hindered to the gas seal. 2, the crankshaft ventilator can not filter the oil and guide the oil into the intake port, which only improves the filter oil mechanism to eliminate the failure or improve the efficiency. 3, leakage of oil from the piston, which shows that the throttle has only carbon in the exhaust side, but the most harmful, mainly due to the poor quality of the piston and piston ring, or the lack of technological precision, but this is only the image, because the current engine materials are all half a Jin of 82, then the same material, the same. Displacement (take 1.6L engine as an example): some engines use short stroke, large cylinder piston, so the area of the piston ring bearing gas oil energy is far larger than the small diameter long stroke, so the area of the piston ring bearing gas oil energy is small, then the push and pull force of the piston ring to the piston ring is different under the same displacement. The greater the tensile force, the greater the destructive force of piston ring on piston. Under the turbine, the piston ring bears more energy and fuel, and the piston ring has greater destructive power on the piston, which further aggravate the degree of burning oil. (Note: the piston ring is stuck in the piston slot, the greater the energy of the piston ring, the greater the damage to the piston slot; if the piston groove has problems, the piston ring can not seal the cylinder and burn the oil). The simple and quick way to solve the oil burning is to add special repair preparations. In particular, the main is the following two kinds: 1, melt casting: on the surface of the friction surface instead of the original metal friction through the soft metal or other special materials (such as the early "TEFLON") Enhance the sealing performance, on the one hand protect the original friction surface metal. This kind of additive can play a role in the initial stage of oil burning, but because its itself is granular and with the flow of oil, it is easy to plug the oil and filter core and cause a greater failure. In addition, because of its small hardness, it will gradually lose with the use of the oil, and the oil will also be discharged with the oil when the oil is replaced, and it needs to be added continuously. 2, forging: forging the metal on the friction surface through the internal heat and high pressure of the engine, forming a new friction surface, increasing the size of the original workpiece, strengthening the seal, and protecting the original friction surface. This kind of additives is relatively rare in the market at present. If sufficient conditions can be made, it can be added in a short term or even long time without adding one time. Although the two additives can alleviate the phenomenon of burning oil to a certain extent, it is necessary to remind that additives can not solve the problem of burning oil. Because the price of the additives is not cheap. If used frequently, it will not be long before the cost of repairing the engine is the same, but it is not as reliable as repairing the engine. Avoiding oil burning prevention is the key to avoid engine oil burning as a whole is to use qualified and suitable lubricating oil and replace it regularly. However, it is important to pay attention to the different design concepts of vehicle engines in various countries. Therefore, the cost of repair and the effect of repair are very different for different countries. A general and practical suggestion is to use oil regularly and replace it regularly. In addition, the European and American engines are generally less than the daily engine in the seal and precision, so the engine (such as the Volkswagen EA888 engine) will check the working condition of the engine (such as the Volkswagen series engine), and check the oil consumption regularly. If there is a problem or abnormal phenomenon, it should be sent to the regular shop for maintenance inspection immediately, not to continue to drive long distance, so as not to cause greater loss or even affect the safety of driving. Some of the oil is designed as a result of the design, which is the main part of the owners' complaints at present: there is no fault in the vehicle, but the oil consumption is very large. In addition, the European and American engines are generally less than the daily engine in the seal and precision, so the engine (such as the Volkswagen EA888 engine) will check the working condition of the engine (such as the Volkswagen series engine), and check the oil consumption regularly.
