Abstract

The invention relates to specific engine oil for natural gas and gasoline dual-fuel engine and a preparation method thereof. The specific engine oil comprises the following components in percentage by weight: 46.18% of 220N base oil, 15% of 400N base oil, 20% of polyalpha-olefin base oil PAO-10, 0.02% of an antioxidant, 7.0% of a viscosity index improver, 0.02% of a pour point depressant, 1.6% of a complexing agent, 1.7% of a clearing dispersing agent, 4.0% of trinitrogen molybdenum phosphorus oxide, 0.3% of a clearing agent, 1% of zinc borate, 0.3% of an antidetonant, 0.02% of nanocopper, 0.14% of an oiliness agent, 0.42% of an anti-wear agent and 2.3% of an ash-free low-carbon additive. The specific engine oil for natural gas has the beneficial effects that (1) the specific engine oil can meet requirements of two fuels and can be normally used at relatively high and low temperatures; (2) the specific engine oil is prominent high in viscosity index, relatively high in saturability and relatively low in evaporation loss ratio; (3) the specific engine is relatively high in explosion resistance and can meet environment-friendly requirements; (4) the specific engine oil has ultrastrong piston cylinder body repair capacity and excellent heat stability; (5) the specific engine oil is relatively strong in lubricating capacity and relatively low in operation resistance, and the service life is prolonged; and (6) the specific engine oil is relatively strong in oxidization and wear resistance.

Description

technical field [0001] The invention relates to a special engine oil for a dual-fuel engine and a production method thereof, in particular to a special engine oil for a natural gas and gasoline dual-fuel engine and a production method thereof. Background technique [0002] The natural gas dual-fuel vehicle is a new type of alternative fuel vehicle recognized in the world as energy-saving, low-pollution, economical and safe. Generally, there are two sets of fuel supply systems. One system supplies natural gas or liquefied petroleum gas, and the other supplies fuel other than natural gas or liquefied petroleum gas. The two fuel supply systems supply fuel to the cylinder according to a predetermined ratio. For mixed-combustion vehicles, natural gas is a clean energy source, its main component is methane, and the main products after combustion are carbon dioxide and water. Compared with gasoline vehicles, the CO in exhaust emissions is reduced by about 90%, HC by about 50%, NO ...
