Embodiment Construction

[0013] In 220 liters of diesel engine lubricating oil, press the combination additive of 15.5mg content per liter (see composition and content table), its total content is 1.5g, add 520 horsepower 12150 diesel engines after mixing evenly. Start the engine and run it under the condition of rated power of 520 horsepower and rated speed of 2000rpm under full load. By replenishing lubricating oil to maintain the lubricating oil level, measure the lubricating oil consumption of the engine during 50 motorcycle hours. The test results are shown in Table 1. This result is compared with the original machine and can be seen that the lubricating oil consumption in the process of working 50 motor hours under the additive situation is obviously lower than the lubricating oil consumption of the willing machine that does not add the present invention. The friction surface of measuring oil ring and the friction surface of cylinder barrel were newly added with 3um and 2um hardness layers after ...

Abstract

The invention discloses an additive-containing lubricating oil. The weight-to-volume ratio of additives to lubricating oil is 7.5-12.5 mg / L. The additives comprise 20% of potassium oxide, 25% of magnesium hydroxysilicate powder, 10% of fine silicon oxide short fiber, 20% of shredded aluminum silicate and 25% of sodium hydroxide. The chemical composition of the magnesium hydroxysilicate powder is Mg,Si,O,o(OH), and the powder particle diameter is less than 5 mu m; the chemical composition of the fine silicon oxide short fiber is SiO, the diameter is less than 1 mu m, and the length is less than 20 L; and the thickness of the shredded aluminum silicate is less than 2 mu m, and the plane size is less than 6 mu m. The additives in the lubricating oil can be directly added into the lubricating oil, or added into the lubricating oil after adding the additives into various greases to prepare a liquid or viscous cream, or directly added to the frictional part surface in other modes.

Description

technical field [0001] The invention relates to a lubricating oil containing additives, which belongs to the technical field of fuels. Background technique [0002] When the engine is working, its internal piston rings, cylinder liners, crankshafts, bushings, gears and other moving parts are in a state of mutual friction. After the engine works for a certain period of time, due to the friction and wear on the surface of the moving parts, the surface roughness of the parts increases and the sealing performance decreases, which makes the engine heat increase and output power decrease, and the lubricating oil consumption increases sharply due to the lubricating oil entering the combustion chamber. The carbon monoxide content in the exhaust gas increases. Therefore, it is necessary to regularly repair or replace the worn parts in the engine, that is, to carry out an overhaul. [0003] In order to reduce the friction and wear of engine parts and prolong the overhaul period of t...
