Abstract
The invention discloses cooling lubricating oil for a natural gas engine. The cooling lubricating oil is characterized by comprising the following substances in parts by weight: 55-70 parts of mineral basic oil, 5-15 parts of 2, 6-di-tertiary butyl p-cresol, 0.1-1.5 parts of a pour point depressant, 0.5-1.5 parts of a dispersant, 0.1-0.7 part of an anti-rust agent, 1-3 parts of a thickener, 3-5 parts of boronized polyisocrotyl succinimide, 0.1-0.5 part of an anti-foaming agent, 2-15 parts of dimethylaniline, 0.5-2.5 parts of N, N-dimethylformamide, 0.1-0.7 part of sodium citrate and 1-5 parts of triethanolamine. The cooling lubricating oil disclosed by the invention has the beneficial effects that due to relatively low ash content, generation of sediment such as greasy filth and carbon deposition can be reduced and the wear of the engine is effectively reduced, the service life of the engine is prolonged, and the engine is prevented from being ignited in advance; and due to good anti-nitrating and anti-oxidizing performances, the lubricating oil can be prevented from being quickly aged and deteriorated, the service life of the lubricating oil is prolonged; the cooling lubricating oil has a good cooling performance.
Description
Technical field
The present invention relates to a kind of cutting oil used for natural gas engine.
Background technology
Along with the control of China to air quality and the requirement to motor vehicle emission are more strict, natural gas engine has become the first-selection that automobile solves emission pollution problem.And natural gas engine needs to use lubricating oil used for natural gas engine, the use of natural gas engine oil and the type of engine type, Sweet natural gas are relevant with organizing the factors such as operating mode, use is that the plain oil of fuel can produce following deficiency with petrol and diesel oil: natural gas temperature of combustion is high, NOx can be increased generate, plain oil is easy to oxidation and nitration, the materials such as easy formation greasy filth, carbon distribution, cause the easy scuffing of cylinder bore of engine, wear and lubricate oil degradation; Sweet natural gas not sulfur-bearing etc., requires that the lubricating oil ash used is low, and plain oil can cause engine to strike sparks in advance and sparking plug blocking because ash content is too high; The poor cooling performance of natural gas engine, can increase the thermal load of engine, and therefore the antioxidant property of regular motoroil and high temperature detergent-dispersant performance all can not reach requirement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cutting oil used for natural gas engine.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of cutting oil used for natural gas engine, it is characterized in that, comprise the material of following parts by weight: mineral base oil 55-70 part, 2, 6-ditertbutylparacresol 5-15 part, pour point depressant 0.1-1.5 part, dispersion agent 0.5-1.5 part, rust-preventive agent 0.1-0.7 part, thickening material 1-3 part, boronation polyisobutylene succinamide 3-5 part, kilfoam 0.1-0.5 part, , xylidine 2-15 part, N, dinethylformamide 0.5-2.5 part, Trisodium Citrate 0.1-0.7 part, trolamine 1-5 part.
The invention has the beneficial effects as follows: there is lower ash content, the sedimental generation such as greasy filth and carbon distribution can be reduced, thus effectively reduce the wearing and tearing of engine, extend the work-ing life of engine, prevent engine from striking sparks in advance; There is good anti-nitrated and antioxidant property, prevent lubricating oil rapid ageing from going bad, extend the work-ing life of lubricating oil; There is good cooling performance.
