Formula as well as production technology of special lubricating oil for dual-fuel engine

Abstract

The invention relates to a formula and a production technology of special lubricating oil for a dual-fuel engine. The lubricating oil is characterized by comprising base oil and an additive, wherein imported hydrogenated mineral base oil 500SN and 150SN are adopted as the base oil, the additive consists of a complexing agent S1880, a viscosity index improver OCP, a pour point depressant 1-248 and an anti-foaming agent T901, and the base oil and the additive are mixed according to a certain proportion. The lubricating oil is prepared by refining and blending hydrogenated base oil and special complex additives for imported dual fuels, and has better anti-oxidization capability and nitration resisting stability at higher temperature; the lubricating oil has protection and more excellent lubrication effects on parts difficult to lubricate, and can reduce the emission of harmful gas and generation of waste engine oil to purify the environment; the lubricating oil has excellent cleanliness and dispersion properties, and the generation of oil sludge and carbon deposit can be effectively inhibited, so that the engine can be cleaner, the oil is not easily aged, and the service life of the engine can be prolonged.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a special lubricating oil formula for a dual-fuel engine and a production process thereof. Background technique [0002] With the gradual enhancement of people's awareness of energy saving and environmental protection, countries have stricter air quality control and vehicle emission requirements. All countries in the world are committed to solving environmental protection and energy utilization problems in the automotive field, and have continuously developed alternative fuel vehicles. Among them, the ideal ones are vehicles fueled by compressed natural gas (CNG) and liquefied petroleum gas (LPG), which impose new requirements on engine oil. Gas fuel engine oil is a new generation of engine oil completely different from gasoline engine oil and diesel engine oil in the past, because of its high fuel combustion value, complete combustion, greatly reduced vehicle exhaust emissions, an...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a special lubricating oil formula for dual-fuel engines and its production process. The common engine oil on the market lacks sufficient lubrication protection for dual-fuel vehicles. , because the fuel gas is dry and the calorific value is higher than that of ordinary fuel, it is easy to cause abnormal wear or failure of the engine; the deposits produced by high ash cause wear of engine parts, spark plug plugging, ablation and carbon deposits in valves, prone to engine knocking, ignition If the fire is not timely and the valve is sprayed, the valve will be deformed, resulting in engine weakness, power instability and other problems, resulting in shortened engine life, valve wear, and lax closure, resulting in a drop in engine power, or failure to work, generating a large amount of sludge, clogging the oil circuit or generating Harmful substances such as paint film will cause the car to stop, deflagration engine abnormal noise, power drop and other reflections. Aiming at the characteristics that ordinary engine oil cannot meet the working conditions of dual-fuel engines, this invention uses hydrogenated base oil and imported dual-fuel special composite additives to refine Reconciled, it has better anti-oxidation ability and anti-nitrification stability at higher temperatures; it has protection and better lubricating effect on difficult-to-lubricate parts; reduces harmful gas emissions, reduces waste oil production, and purifies the environment; excellent Clean and dispersive properties, effectively inhibit the generation of sludge and carbon deposits, make the engine cleaner, make the oil not easy to age, and prolong the service life of the engine
