Four-stroke motorcycle plus lubricant three bogey

Posted on

Lubricating oil, commonly known as motor oil. The standard for lubricating oil for motorcycles is that the lubricating oil surface of the engine oil sump should be located between the upper and lower lines of the oil gauge. If the lubricating oil is improperly added, it will cause harm to the motorcycle. Therefore, there are “three bogeys” for lubricating motorcycles:

Do not add too much

Some motorcycle drivers are eager to save trouble, and they are afraid of trouble. In order to avoid the lack of engine oil during long driving, when adding oil, it greatly exceeds the scale line on the curved ruler. The result of this work is that if there is too much oil in the engine oil sump, it will easily break into the combustion chamber, causing the exhaust pipe to emit blue smoke, which will not only increase the fuel consumption of the engine, but also the unburned. The oil will also generate a lot of carbon deposits on the top of the piston and the valve seat, which will aggravate the wear of mechanical parts and even cause the piston to die. Therefore, the lubricant can not be added.

Second bogey

Some motorcycle drivers, when checking the oil before driving, found that the oil was below the oil marker line, but they were able to take time to grab the time or because there was no oil to add. The result is: because the oil level of the oil sump is too low, the motorcycle is working on the downhill, over the sill or the brakes; it is possible to expose the oil filter to the oil surface, so that the oil pump can not supply oil, which causes Burning tile "sticking cylinder" and other serious accidents. Therefore, when the oil pan surface is lower than the oil scale line, it is necessary to add lubricating oil.

Three bogey old and new mixed

Some motorized sheep drivers do not replace the old engine oil that has been scrapped, but add some new oil to the old oil. After mixing, continue to use it. It is considered that this can save oil, which is actually wrong. The old engine oil contains substances with strong oxidizing ability, and the old and new oils can mix, which can accelerate the oxidative deterioration of new and old oils, reduce the use effect and use time of new oil, and the old lubricating oil has a long lubricating time and is easy to cause serious wear and smoke. As a result, the life of the power machine is affected: therefore, when the oil reaches the end of life, it should be completely discharged, and it can not be mixed with old and new!
