Problems solved by technology

However, under the condition of high temperature, high speed, low temperature and low speed, it is easy to generate black sludge in the engine cylinder, and the accumulated black sludge is easy to agglomerate in the cylinder, which becomes a hard node that damages the cylinder surface and piston ring. , increasing the consumption of fuel and lubricating oil
If it is not cleared in time, it will reduce the effective power of the engine and increase the emission of PM2.5 particulate matter in the exhaust

Embodiment 1

[0020] ①After drying the kaolinite at 400°C for 3 hours, grind it in a ball mill to a particle size of no more than 1 micron;

[0021] ② Weigh 10g of kaolinite obtained in step ①, 70g of SJ gasoline engine oil, 1g of calcium oxide, 1g of fatty amine polyoxyethylene ether and mix them into a homogenizer with a closed device to make the vacuum degree reach -0.08MPa;

[0022] ③Raise the temperature to 85°C, stir at 10000rmp for 30min, adjust the rotation speed to 18000rmp for 10min, and adjust the rotation speed to 28000rmp for 5min;

[0023] ④ Finely disperse in an 80W, 35KHz ultrasonic generator for 10 minutes.

[0024] The prepared new lubricant was subjected to a wear test on a MMW-1 vertical universal friction and wear machine with a test force of 800N and a rotational speed of 2000r / min. After 5 hours of wear test, the sample changed from 2.9550g to 2.9561g, and the weight loss was -0.037%, which means that the sample not only did not decrease, but also increased in weight...

[0026] ①After drying the kaolinite at 400°C for 3 hours, grind it in a ball mill to a particle size of no more than 1 micron;

[0027] ② Weigh 13g of kaolinite obtained in step ①, 75g of SJ gasoline engine oil, 2g of calcium oxide, 1.6g of fatty amine polyoxyethylene ether and mix them into a homogenizer with a closed device to make the vacuum degree reach -0.08MPa;

[0028] ③Raise the temperature to 85°C, stir at 10000rmp for 30min, adjust the rotation speed to 18000rmp for 10min, and adjust the rotation speed to 28000rmp for 5min;

[0029] ④ Finely disperse in an 80W, 35KHz ultrasonic generator for 10 minutes.

[0030] The prepared new lubricant was subjected to a wear test on a MMW-1 vertical universal friction and wear machine with a test force of 800N and a rotational speed of 2000r / min. After 5 hours of wear test, the sample changed from 2.9576g to 2.9589g, and the weight loss was -0.04%, which means that the sample not only did not decrease, but also increased in weigh...

Abstract

A novel SJ gasoline engine oil composition comprises the following components, by mass, 70-80 parts of SJ gasoline engine oil, 10-15 parts of kaolinite, 1-3 parts of calcium oxide and 1-2 parts of fatty amine polyoxyethylene ether. The prepared novel SJ gasoline engine oil composition can rapidly form superhard wear layers in the cylinder of an engine and on a piston ring, so problems of no activity of an extreme-pressure antiwear material in present lubrication mediums, no wear layer formation, or discontinuousness and loose structures of the formed wear layers are solved. The effective power of the engine is maintained, and the discharge of exhaust PM2.5 particles is reduced; and the consumption of a lubrication material is also saved, so the environmental protection effect is reached. The composition has the advantages of easily available raw materials, scientific formula, simple preparation technology, low cost, and good performances, and can be especially applied to the lubrication of various novel racing cars and top-level cars.

Description

technical field [0001] The invention relates to a novel SJ gasoline engine oil composition, in particular to a gasoline engine oil composition used in various models, racing cars, and top cars, and belongs to the field of material technology. Background technique [0002] All kinds of new models, racing cars, and top-level sedan engines have large displacement and fast start-up speed. It is required that the engine is easy to start at low temperature, maintain oil pressure and comprehensive good lubrication at high temperature, and prevent engine wear, rust and deposits formed by oil oxides. Keep the engine clean, lubricating oil has good viscosity stability and low lubricating oil consumption. However, under the condition of high temperature, high speed, low temperature and low speed, it is easy to generate black sludge in the engine cylinder, and the accumulated black sludge is easy to agglomerate in the cylinder, which becomes a hard node that damages the cylinder surface...
