【Car owner's car knowledge】How does the engine burn oil? How to judge whether the engine burns oil? How to deal with this situation? Last week, the car owner's home interviewed Mingjia Hyundai's after-sales service experts. A very serious problem, if the "burning oil" is serious, it may cause the engine to be scrapped. At the same time, he also suggested that car owners, in the actual driving process, to judge whether the car is burning oil, the easiest way is to see whether the exhaust pipe emits blue smoke.
Fault phenomenon: blue smoke from exhaust
According to experts, in the actual driving process, if the exhaust pipe emits blue smoke, the engine vibrates at idle speed, and the engine oil is seriously lacking in a routine maintenance (oil change) cycle (no dripping phenomenon), then your love The car may be burning oil. Among them, when the car is cold and "burning oil", when the car is driven for the first time every morning, there will be relatively thick blue smoke discharged from the rear exhaust pipe. After a period of time, the blue smoke will disappear, and the similar situation will generally not happen again on the same day; when the vehicle is driving, the driver slams on the accelerator or slams on the accelerator, and a large amou

Among them, when the car is cold and "burning oil", when the car is driven for the first time every morning, there will be relatively thick blue smoke discharged from the rear exhaust pipe. After a period of time, the blue smoke will disappear, and the similar situation will generally not happen again on the same day; when the vehicle is driving, the driver slams on the accelerator or slams on the accelerator, and a large amount of gas is discharged from the exhaust pipe. In the case of blue smoke, the driver can see blue smoke from the reflector on the side of the exhaust pipe after the driver slams the accelerator while the vehicle is driving.
During the interview, the expert also told reporters that if the car owner suspects that his car is burning oil, he can fill up the car with oil, let the car travel 1,000 kilometers and go to the maintenance station to weigh the oil filter, then refill the oil, and then let the car. Drive 1000 kilometers. Repeat this three times to obtain an average value. The normal consumption of oil after the running-in period can generally reach 1L/1000km. If it exceeds the standard, the engine must be repaired.
Consequences: May cause the engine to be scrapped
According to Lu Jingen, the so-called "burning oil" means that the oil enters the combustion chamber of the engine and participates in the combustion together with the air-fuel mixture. The phenomenon of "burning oil" in the vehicle will cause the vehicle's oxygen sensor to be damaged too quickly, resulting in increased carbon deposits in the combustion chamber, unstable idling, weak acceleration, increased fuel consumption, and excessive exhaust emissions. Cause irreparable damage or even scrap, resulting in a substantial increase in maintenance costs and even hidden dangers of accidents.
Cause of failure: normal wear + abnormal wear
According to experts, there are two reasons for the engine to burn oil: normal wear and tear, that is, the normal phenomenon of the vehicle after a certain number of kilometers. The average vehicle is about 200,000 kilometers. Different vehicles, different people, and different regions (air dust content) have a great impact on the service life of the engine; abnormal wear and tear is caused by product quality. and early wear caused by improper use.
In addition, the use of substandard oil, not replacing the oil and oil filter over time, starting the cold car with a large throttle, running without oil for a long time, running at a high temperature for a long time, running at a long-term overload and high speed, and long-term poor air quality Running under the condition that the air filter is not replaced when it is good and due, the oil pump is insufficient, the oil pressure is too low, the oil passage is blocked, etc., all of which will cause the engine to burn oil, thereby reducing the service life.
Solution: choose high-quality oil
In order to prevent cars from burning oil, experts suggest that car owners should choose gasoline with better quality during driving; old cars can use oil with a slightly larger viscosity to increase the sealing between the piston and the cylinder wall. Of course, the ultimate solution to "burning oil" is to carry out a more thorough overhaul of the vehicle to fundamentally solve the problem; check the oil gauge frequently, replace the oil and oil filter regularly, and replace the genuine oil filter according to the requirements of the product instruction manual. Cleaner spare parts; in order to adapt to road conditions, meet the normal operation and service life of the engine, and reduce oil consumption, it is necessary to choose a high-end engine lubricant. Especially for an engine with a turbocharger (its operating temperature is higher), it is more necessary to use a high-quality engine oil with a lower volatilization rate, because oil volatilization is also an important factor that causes the car to "burn oil".
