Engine oil reinforcer

Abstract

The invention relates to the field of marine lubricating oil, and discloses an engine oil reinforcer which comprises 0.5-5 wt% of dialkyl secondary amine, 0.5-10 wt% of alkylamine, 0.5-10 wt% of alkyl hydramine, 5-10 wt% of antiwear additive and 65-93.5 wt% of base oil. When being used in marine medium-speed engine oil, the reinforcer can obviously lower the insoluble impurities in old oil, can disperse the carbon deposits, oil sludge and other solid matters, can lower the in-use oleic acid value to prevent rust, and is capable of reinforcing the alkali number of old oil, effectively prolonging the service time of in-use oil and saving the oil cost, thereby bringing in great economic benefits.

Description

technical field [0001] The invention relates to a marine lubricating oil enhancer, in particular to a marine medium-speed engine oil used oil enhancer. Background technique [0002] Marine engines can be divided into two strokes and four strokes according to the stroke. Among them, the four-stroke engine is often a plunger engine, and the lubricating oil used is a medium-speed engine oil, which is characterized by one-time filling and long-term use. Since the fuel used in marine engines is mostly heavy fuel, the fuel contains more asphaltenes. When the engine is abnormal, poor combustion will occur, and heavy fuel will leak into the crankcase through the combustion chamber, resulting in changes in the performance of the lubricating oil. [0003] Because the combustion chamber will generate high temperature and high pressure when the fuel is burning, it is easy to generate carbon deposits on the piston head; at the same time, high temperature and high pressure will also the...

Problems solved by technology

Although this method can effectively alleviate the use of lubricating oil, it will bring a part of the cost every time the new oil is replaced, and at the same time, the disposal of the waste medium-speed engine oil also requires a roadway fee
