Description

Machine oil reinforcing agent
Technical field
Old oil is being used the present invention relates to a kind of marine lubricant reinforcing agent, more particularly to a kind of MARINE MEDIUM SPEED ENGINE OIL Reinforcing agent.
Background technology
Marine engine can be divided into two kinds of two-stroke and four strokes by stroke.Wherein four-stroke engine Chang Weizhu Plug engine, is middling speed machine oil using lubricating oil, and it is once to fill with oily feature, long-term use.By In the fuel mostly heavy fuel that marine engine is used, more asphalitine is contained in fuel.It is different in engine Chang Shi, can produce inefficient combustion, have during heavy fuel leaks into crankcase by combustion chamber, cause lubrication Oiliness can change.
Because combustion chamber is in fuel combustion, high temperature and high pressure can be produced, easily produce product at piston head position Carbon；High temperature, high pressure can also thermally decompose effect to lubricating oil simultaneously, cause lubricating oils from oxidative, produce oil Mud, is deposited on crankcase, causes lubricating oil viscosity to increase, and if the carbon distribution in combustion process passes through not in time Lubricating oil is disperseed, is separated, and easily causes inordinate wear to Engine Cylinder Wall and bent axle position.
Heavy fuel usually contains a certain amount of sulphur, in combustion, meets water and easily forms acidic materials, should Acidic materials not only denude the first-class metal portion position of piston, and easily to being caused between engine piston ring, casing wall Corrosion.And the detersive in lubricating oil, such acidic materials just can be effectively neutralized, protect engine not receive Corrosion.But with the long-play of engine, detersive is gradually consumed, its neutralization to acidic materials Ability gradually weakens, i.e., its base number constantly declines.
For all the foregoing reasons, ship use intermediate speed machine is after a period of time is run, and its middling speed machine oil used is usual Viscosity can increase, and base number declines, and oil product insolubles content increases, and oil product cleannes are also deteriorated.Usual ship Lubricating management personnel's way is when engine is repaired, the old oil of middling speed machine oil all to be changed.Although this Method can effectively alleviate lubricating oil and use, but replacing fresh oil can bring a part of expense every time, while discarded Medium speed engine oil processing is also required to entrance to a lane expense.
Therefore, a kind of middling speed machine oil reinforcing agent that can effectively extend the old oily use time of middling speed machine oil is invented just to show Must be highly desirable to.
