Description
Technical field
The present invention relates to the lubricating oil that a kind of oil engine uses, be applicable to the multi-stage combustion engine oil and the production method thereof of pluralities of fuel, multiple structure.
Background technology
Common multi-stage combustion engine oil is by the low viscosity base oil and refining property oil 150BS bright stock adds high molecular polymer (viscosity modifier) and other lubricating oil functional additives are formulated, claims multiviscosity oil again.The outstanding advantage of multi-grade oil is that viscosity temperature characteristic is good.Multi-grade oil can use under-20-45 ℃ temperature condition.Therefore, usually this multi-grade oil is called summer in winter all-purpose engine oil again.Multi-grade oil is a kind of I. C. engine oil of large span, and it is compared with general I. C. engine oil (single-stage oil) has tangible advantage, and mainly contain: 1, cold starting performance is good.During cold starting, the I. C. engine oil low-temperature fluidity is good at low temperatures for engine, and the resistance during engine start is just little, and the engine cold starting performance is just good more.The low-temperature fluidity of multi-grade oil is better than the oily low-temperature fluidity of single-stage, and its cold starting performance might as well.2, versatility is good.Multi-grade oil has good viscosity temperature characteristic, the multifunctional efficient recombiner.The change of the viscosity with temperature of multi-grade oil and the degree that changes is littler than single-stage I. C. engine oil.It has elastic fluid character, and its under shearing (when turning round as pump, bearing or piston-cylinder) produces instantaneous viscosity degradation, recovers original viscosity again after shearing is removed.Its viscosity when low temperature is not too big, and during high temperature viscosity reduce less, good fluidity, resistance to flow is little, oil pump does not need too big pressure can make oil circuit unimpeded, can guarantee the normal lubricated of body friction surface.It can fully take into account the requirement of engine cold starting and normally lubricated two aspects of high temperature, therefore.Multi-grade oil north and south for a long time is general general with the summer in winter.Needn't change different machine oil with the difference in season because of the area.Versatility also finds expression in vapour, the general oil of diesel engine oil.It makes things convenient for mixed fleet to use, and both can be that single-stage oil also can be multi-grade oil, simplifies the machine oil kind, is convenient to management, prevents to misuse machine oil, brings for use department and greatly facilitates and benefit.Simultaneously, for manufacturing enterprise,, all will bring convenience and tangible economic benefit to aspects such as oil product blending storage, transportations owing to simplify kind.3, good economy performance.Oil engine can reliably promptly start under the low temperature after using multi-grade oil, can reach natural running temperature in the short period of time, avoids because of starting difficulty makes the long-term or interruption idle running of engine, and is favourable to the frictional wear that reduces engine.Simultaneously also reduce the energy consumption that the friction resistance when normal operation work causes, have the good fuel economy.For diesel locomotive, can also reduce engine number of starts and the time in the winter time, help reducing fuel consumption.Therefore, multi-grade oil is used at least on diesel locomotive and can be saved diesel oil 1-2%.In addition, it is better that viscosity changes little, vibration damping, rust-preventing characteristic, cooling, oilness, stopping property, cleaning under the multi-grade oil high temperature, can reduce the wastage in bulk or weight 10-20% of fuel.
Last century the mid-50 developed country begun to the full-scale development of multi-grade oil with apply.At first, multi-grade oil is used on the petrol motor of car, also begins afterwards to adopt on diesel engine.Multi-grade oil and single-stage oil phase are than having above-mentioned superiority, and its outstanding advantage is that sticking warm nature is good, is adapted to the large span temperature range and uses, and is convenient to engine low-temperature starting-up.And can improve oil film thickness and intensity, and on automobile, use and can save fuel oil 1-4%, therefore, over more than 20 year, multi-grade oil has obtained developing rapidly.At present, in U.S.'s I. C. engine oil, the petrol motor multi-grade oil accounts for 75%, and diesel engine accounts for 45%, and West Europe has also surpassed 50%, and the trend that progressively replaces single-stage oil is arranged greatly.Since the seventies, because the world energy sources crisis, fuel price rises, and European and American countries is attached great importance to fuel-economizing, and people take the problem of using multi-grade oil on the combustion locomotive again into account.The technical literature data of abroad delivering recently shows that diesel locomotive uses the technical problem of multi-grade oil to solve.The U.S., European Union, Japan and other countries have all obtained good experience in this respect.
From present both at home and abroad technology trends, oil engine forward direction speed, heavy loading, high-power, improve unit weight output rating direction and develop, its working condition is harsh more.Therefore; it is that long lifetime oil is the technology trend direction of current I. C. engine oil development that multistage general, energy-saving and environmental protection, the many fuel of adaptation and multiple structure oil engine use; the development of I. C. engine oil new variety high standard mainly is the requirement of satisfying legislations of environmental protection and save energy both at home and abroad.Europe, Japan and the U.S. are because automobile and prime mover industry development dog-eat-dog, and novel texture and high-performance enginer constantly occur, and to high-power, at a high speed, the direction of heavy loading, shock and vibration load, high pressure charging, many fuel, low emission develops.Important promoter action is played in the development of corresponding I. C. engine oil, and gasoline engine oil develops into the SL level at present, and diesel engine oil is to the CI-4 level.And multi-grade oil develops into the SG/CF-4 level.Adapt to and to have only double fuel (being that gasoline, geseous fuel or pure type burn) with many fuel aspect.China quotes the API corresponding standard of the U.S. basically, and the standard of European Union is then adopted in environmental protection.So, be the demand of complying with market for making things convenient for the client and helping environmental protection development multi-stage combustion engine oil.
