Problems solved by technology

[0006] Natural gas is a dry fuel. Unlike gasoline and diesel, it has a lubricating effect on the intake and exhaust valves during use, and it is easy to cause wear and embedding of the valves.
This is a problem unique to the use of gaseous fuel, which can only be balanced by controlling the ash content of the lubricating oil. Too low ash content will cause valve wear and embedding; too high ash content will cause spark plug blockage, valve fire, combustion chamber deposits and explosion shock

Embodiment 1、5

[0044] The deployment of embodiment 1, 5W / 30ACEAA5-02 (APISM) oil / gas general internal combustion engine oil:

[0045] Add 150N315g.500N35g, PAO6400g (Chevron product sold by Nanjing Xinhuayuan Chemical Co., Ltd., Shell product sold by Shanghai Qicheng Industrial Co., Ltd.), polyol ester 50g into a 2L open beaker, and heat up to 60°C under stirring. ±2°C. Add SANT-203680g, SANT-608310g, and stir at constant temperature for 10 minutes until the liquid is uniform and transparent. Then add SANT-1088100g, SANT-806810g, stir at constant temperature for 30 minutes, and filter to obtain the finished product.

Embodiment 2、10

[0046] Embodiment 2, the deployment of 10W / 40ACEAA5-02 / CH-4 oil / gas general-purpose internal combustion engine oil:

[0047] Add 220g of 150N, 95g of 500N, 400g of PAO, and 50g of polyol ester into a 2L open beaker, and raise the temperature to 60±2°C while stirring. Add SANT-203695g, SANT-608310g, and stir at constant temperature for 10 minutes until the liquid is uniform and transparent. Then add SANT-1088120g, SANT-806810g, stir at constant temperature for 30 minutes, and filter (400-mesh copper screen twice) to obtain the finished product.

Embodiment 2

[0048] The results of analysis and testing of the refined oil obtained in Example 2 are shown in Table-3.

[0049] The reason for raising the temperature to 60±2°C under stirring in the above examples is that too high a temperature is likely to cause oil oxidation, and too low a temperature is not conducive to the complete dissolution of additives. After long-term practice, the temperature is preferably 60°C. In actual production Among them, the product quality and production efficiency are in the acceptable range at 55-58°C and 62-65°C.

[0050] The raw materials (or components) described in the present invention are divided into additives and base oils;

[0051] The additives are: SANT-1088 environment-friendly high-grade internal combustion engine composite agent; SANT-2036 dispersed VI improver; SANT-6083 low-temperature fluidity improver, SANT-8068 environment-friendly energy-saving friction reducer; the above additives come from Chengdu Sanxin Chemical Application Techno...

Abstract

Oil-gas universal internal combustion engine oil comprises 8-12% of SANT-1088, 7-11% of SANT-2036, 0.5-5% of SANT-6083, 0.5-5% of SANT-8068, 20-40% of 150N, 0-40% of 500N, 0-10% of 150 BS, 40-60% of poly-a-olefin synthetic oil, 5-20% of alcohol ester.The oil-gas universal internal combustion engine oil includes steps of mixing 150N, 500N, 150 BS, the poly-a-olefin synthetic oil, and alcohol ester proportionally; heating the mixture to 55-65 DEG C; adding SANT-2036, SAMT-6083, SANT-1088, and SANT-8068 proportionally, and uniformly stirring at 55-65 DEG C.The oil-gas universal internal combustion engine oil is low in viscosity, multi-step, low in volatility, excellent in oxidation stability, and suitable for dual-fuel engines and service life is prolonged.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a lubricating oil for a dual-fuel internal combustion engine. Oil and gas general internal combustion engine oil [0002] It can also be called gas / oil general-purpose internal combustion engine oil, or energy-saving and environment-friendly oil / gas general-purpose high-grade internal combustion engine oil. Background technique [0003] At present, taxis in big cities in my country mostly use natural gas and gasoline or diesel as fuel, while engine lubricating oil uses commercially available gasoline engine lubricating oil or diesel engine lubricating oil. Practice has shown that after gasoline vehicles are switched to natural gas, the disadvantages of continuing to use gasoline engine lubricating oil are that the lubricating oil will be easily nitrated, oxidized and deteriorated, and the service life will be greatly shortened. According to survey statistics, the oil change cycle of the lub...
