Oil is the core of keeping the car's power system running normally, so car owners are also particularly careful about how to choose oil in daily maintenance, and they will learn how to maintain the engine when they are idle. Because the technical difficulty of changing oil and adding oil to the car is not large, many car owners will buy unified titanium oil in the auto supplies store to change the oil themselves. Of course, sometimes there will be "good intentions to do bad things" of the owner will add more oil, encounter this situation must be dealt with in time, otherwise it will lead to a series of problems in the engine.
First of all, the current automobile engine lubrication method mostly uses pressure injection and splash lubrication. That is, the oil pump directly extracts the oil from the oil pan and filters it and then sprays it to the crankshaft journal and other parts to produce lubrication. The cylinder wall and other parts rely on the oil flowing down after injection for lubrication. When the oil is added, it will cause the components in the crankcase to increase the running resistance, in order to maintain power, the engine needs to consume more fuel, and the car will also produce a sticky feeling when it speeds up.
Secondly, when the oil is added more, it will rise with the engine speed, a large number of bubbles will be generated in the oil, if the bubbles are sucked by the oil pump, the oil supply interval will occur when the lubricating oil is injected, and when the engine cannot be continuously lubricated, it is easy to cause the cylinder to be pulled.
In addition, excess oil will also flow to the cylinder wall and other places, which will increase the piston resistance, a small amount of oil will even be forced to penetrate the piston ring under pressure into the combustion chamber, after mixing combustion to produce carbon deposits. When the carbon deposit is not disposed of in time, it will also block the hole of the three-way catalytic converter, and another part of the carbon deposit through the three-way catalytic converter will be discharged from the exhaust pipe, which is what we often call burning oil.
Of course, the oil is not enough, when the amount of oil is lower than the MIN tick line, the oil pump can not extract the oil from the oil pan to transport to the lubrication parts, which will cause abnormal wear to the engine at this time, resulting in a reduction in engine life. So how much oil is appropriate?
In fact, the amount of oil in the oil pan as long as kept between MIN and MAX can be, because when the vehicle is driving at high speed, the oil will become thin due to the high temperature of the engine, if the amount of oil is too small, it will cause poor lubrication, and it needs to be added when the middle position of the tick mark is reached.
In addition, the oil will produce a small amount of consumption during the operation of the engine, so the owners should develop the habit of checking the oil level regularly, and pay attention to adding it at any time when the amount of oil is small. Experienced drivers who often run long distances will generally prepare 1L of unified titanium oil in the car, and the small size packaging is very easy to carry.
