The last chapter, Xiaobian tell you briefly introduces the difference between mineral and synthetic oils, but they use the difference between the last chapter, small make up with everyone simply introduced the distinction between mineral and synthetic oils,but they use the difference between what is:
The ordinary engine general speed in million to the following, so in this case, or can use an ordinary mineral oil. But if you are a high speed engine (such as large reductions in racing), due to the high speed engine speed can reach to more than 20000. So this time the ordinary mineral oil cannot hold. Due to the high temperatureand high speed, lubrication of discount. Then there are the possible scuffing, and even cause serious consequences. So, in the competition, should fully synthetic oilwith high performance.
The engine when activated, especially activated at low temperatures will produceconsiderable wear. Plain mineral oil due to the cold weather poor mobility, cold state,on the workpiece surface oil film is very thin, the moment to start, due to insufficient lubrication, wear greatly. The synthetic oil can flow freely at very low temperatures,can reach any part of the engine and the valve drive mechanism quickly. Andsynthetic oil has good adhesion, can form oil film thick on the workpiece, can significantly reduce the loss caused by friction.
When the engine is operating at very high temperatures, high temperature can makelubricating oil oxidation, resulting in oil thickening. Therefore, ordinary mineral oil in the engine when working for a long time, the sound of the engine change, sometimes"Dangdang" noise, lubrication in the high temperature condition which is the oilbecomes poor performance, wear more. The synthetic oil added high performance fluid and enhanced antioxidant formula, even at high temperature of 204 Celsius, also can have very good antioxidant properties.
The engine after a long time, due to the combustion of gasoline, oil degradation and the formation of oil sludge, easy to plug the oil passage, prevent oil flow, even cause the piston ring. It can be seen that have a look out the waste oil. Plain mineral oil infree, transparent, and some even is transparent. Balanced additive combination of synthetic oil can prevent deposition and sludge. So the synthetic oil, put out is very black.
Can be seen from the above points, you know the difference between mineral and synthetic oils used to do, if you just put the car when the traffic tools, then use the domestic oil genuine enough. If you love, then let it work better.
Reminder.
Chronicles and the electromechanical device limited company to recommend air compressor, water heater, air compressor heat recovery equipment, as long as youhave the air compressor factory, can 0 operation cost of producing hot water andheating.
