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...
