Rich fuel multi-grade environmental protection type oil for internal comustion engine and its production method

Abstract

The invention discloses a multi-fuel multistage environmental-protection internal-combustion oil, composed of mineral basal oil and hydrogenated plant oil, oil residue HVI150BS bright recombinant oil and compound additive, it can adapt to different-structural internal-combustion engines, including: gasoline engine, turbine pressure diesel engine, ship diesel engine, locomotive diesel engine, multirotor engine, adaptive to different-fuel automobiles, adaptive to the vehicles used in the winter and the summer, adopting closed-loop electrojet machine inner-purifying technique and converting tertiary tail gas, and has better degradability, lower environmental protection after leaked or used as compared with existing internal-combustion oil, and because its degradation ratio reaches 80%, it relatively reasonably solves the compounding of high-efficacy clean disperser with high-temperature antioxidant, and also solves problems of low discharge, low-temperature fluidity, high-temperature dispersivity and key low ash content.

Description

technical field [0001] The invention relates to a lubricating oil used in an internal combustion engine, which is a multi-stage internal combustion engine oil suitable for various fuels and various structures and a production method thereof. Background technique [0002] The usual multi-grade internal combustion engine oil is formulated from low-viscosity base oil and refined oil 150BS bright oil plus high molecular polymer (viscosity modifier) ​​and other lubricating oil functional additives, also known as thickened engine oil. The outstanding advantage of multi-grade oil is good viscosity-temperature performance. Multi-grade oil can be used under the temperature condition of -20-45 ℃. Therefore, this kind of multi-grade oil is usually called winter and summer general-purpose lubricating oil. Multi-grade oil is a kind of long-span internal combustion engine oil. Compared with general internal combustion engine oil (single-grade oil), it has obvious advantages, mainly as f...

Problems solved by technology

[0006] Most of the internal combustion engine oils reported in the above-mentioned open literature emphasize their anti-wear performance, pour point depressing, anti-foaming and other functions, but these internal combustion engine oils are highly targeted and cannot be adapted to work under the working conditions of internal combustion engines of different structures and using different fuels at the same time. However, it is difficult to meet the requirements of national environmental protection regulations in terms of emissions.

Moreover, there is basically no natural degradation ability after use. If it is leaked and discharged into the environment, it will cause long-term pollution.
