Embodiment Construction
[0049] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0050] Preferably, the base oil comprises the following mass percentages:
[0051]
[0052] refer to figure 1 A kind of preparation method of dual-fuel engine oil shown:
[0053] Base oil 150N100℃ kinematic viscosity 5.30mm 2 / s; base oil 500N100℃ kinematic viscosity 10.20mm 2 / s, polyol ester 100°C kinematic viscosity 20.00mm 2 / s, when the viscosity index is 140. In this example, all raw materials are measured according to the patent formula, including the following preparation steps:
[0054] 1) Transfer the measured Class II hydrorefined mineral base oil 500N and Class II hydrorefined mineral base oil 150N into a specific blending rea...

The invention discloses dual-fuel engine oil and a preparation method thereof. The dual-fuel engine oil comprises a composition formed by a gasoline-gas dual-fuel engine oil complex agent P5274, a diesel-gas dual-fuel engine oil complex agent D3384, a non-dispersive viscosity index improver OCP, a pour point reducer T803B, a high-temperature antioxidant T557, an antifoaming agent, a friction improver T1003, base oil and the like. By adopting the dual-fuel engine oil disclosed by the invention, the problems of excessively fast oxidative deterioration of engine oil, shortening of oil change period, oil line blocking by a large amount of oil sludge, engine component wear caused by harmful substances such as paint film and consequent reduction of engine life, valve wear and untight closing caused by dry fuel gas, mechanical excessive wear caused by insufficient wear resistance and the like in a dual-fuel vehicle using regular engine oil can be effectively solved.
Description
technical field [0001] The invention relates to a dual-fuel engine oil and a preparation method thereof. Background technique [0002] Automotive fuel mainly refers to gasoline engine (ignition engine) fuel and diesel engine (compression ignition engine) fuel. They are currently the main source of power for automobiles. With the development of the global economy, the number of automobiles is increasing year by year. It is also becoming more and more serious to the environment and has become one of the main sources of air pollution. Therefore, automobile manufacturers are constantly improving the combustion system of the engine, adopting advanced electronic control technology and high-performance pollution purification devices, and using unleaded gasoline. Alternative fuels and alternative fuel vehicles for environmental protection. Worldwide, the most successful alternative fuels are liquefied petroleum gas (LGP) and compressed natural gas (CNG). After the 1980s, all kind...
