Abstract
The invention discloses a lubricant for natural gas engines. The lubricant comprises the following materials in parts by weight: 50-60 parts of base oil, 0.1-1.5 parts of a depressant, 0.5-3 parts of an antioxigen and antigum agent, 0.5-1.5 parts of a dispersing agent, 0.1-0.7 part of an antirusting agent, 1-3 parts of a thickening agent, 0.1-0.5 part of an anti-foaming agent, 2-15 parts of dimethyl aniline, 0.5-2.5 parts of N, N-dimethylformamide, 0.1-0.7 part of sodium citrate and 1-5 parts of triethanolamine. The lubricant for the natural gas engines has the advantages of being lower in ash content, being capable of reducing the generation of deposits such as sludge and carbon to effectively reduce the engine wear, prolonging the service lives of the engines, and preventing the engines from ignition in advance; the lubricant has excellent nitrification resistance and oxidation resistance to prevent rapid aging and deterioration and prolong the service life, and has excellent cooling performance.
Description
Technical field
The present invention relates to a kind of lubricating 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 lubricating 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 lubricating oil used for natural gas engine, comprises the material of following parts by weight: base oil 50-60 part, pour point depressant 0.1-1.5 part, antioxidizing and antigum agent 0.5-3 part, dispersion agent 0.5-1.5 part, rust-preventive agent 0.1-0.7 part, thickening material 1-3 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.
Preferably, described base oil mineral base oil, described antioxidizing and antigum agent is 2,6 ditertiary butyl p cresol, and described pour point depressant is toluylic acid, and described dispersion agent is boronation polyisobutylene succinamide, and described thickening material is urethane.
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.
