Abstract
The invention discloses a lubricant special for a purified canned biogas engine. According to the lubricant, polyalpha-olefin and class II basic oil are compounded as base oil and the base oil is matched with various composite additives, including a detergent, a dispersant, an antioxidant preservative, an antioxidant, an anti-foaming agent, a metal deactivator and a functional agent. The lubricant special for the purified canned biogas engine has good anti-oxidation and anti-digestive performance, can effectively prevent engine oil oxidative deterioration or sediment production caused by a high temperature, can keep proper ash and avoid wear of engine suction and exhaust valves and valve seats, has superior anti-corrosion performance, can effectively neutralize corrosive substances and the acidic substances produced by oil oxidation and reduce the corrosion to the engine, has prominent anti-wear, anti-friction and extreme pressure properties, can meet the requirement on continuous high-load work of the biogas engine and is suitable for lubricating the purified canned biogas engine system.
Description
Technical field
The invention belongs to explosive motor lubricant, particularly purify canned methane fuelled engine lubricant agent special field.
Background technology
Biogas be organic substance under anaerobic, a kind of inflammable gas generating through the fermentative action of microorganism.Main component is methane and carbon dioxide, also has a small amount of nitrogen, hydrogen and hydrogen sulfide etc.Purify canned methane fuelled engine and generally adopt petrol motor or the petrol motor through changing a social system, single methane fuelled engine is generally formed by gasoline engine refitting, electricity consumption spark ignition biogas-air Mixture.In methane fuelled engine system, biogas combustion speed is slow.Therefore generally adopt high-energy ignition system, increase primary current and the voltage of ignition system, can obviously improve the performance of ignition type methane fuelled engine.Due to the burning kindling temperature higher (632 ℃) of methane, the kindling temperature of biogas is high (645～850 ℃) relatively also, so methane fuelled engine generation tail gas is few, and have excellent emission performance and good anti-knocking property.
Purify and cannedly (removed the most of carbonic acid gas, moisture and the hydrogen sulfide that in biogas, contain, methane content is greater than 90%, canned pressure is 20MPa) Gas application on the identical diesel locomotive of working volume, can obtain higher power, not even lower than the power of former machine.The dynamic performance and the emission behavior that purify canned methane are superior, make to be used widely at engine.Purifying canned methane fuelled engine and be different from regular fuel engine, is different at engine lubrication, resistance to high temperature oxidation, the aspect such as nitrated.Use the lubricant of methane fuelled engine special use, methane fuelled engine system is protected, better hair treatment motivation moving parts, increasing service life of engine.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of anti-oxidant, digestion resistibility good, can effectively prevent engine oil deterioration by oxidation or produce settling, reduces engine breathing valve and the prooving of valve seat; Corrosion resistance is good, wear-resistant, antifriction and extreme pressure property outstanding, can meet the canned methane fuelled engine lubricant agent special of purification of the continuous high capacity work of methane fuelled engine.
The present invention is usingd following technical scheme and is solved the problems of the technologies described above: adopt poly-alpha olefins and II class base oil compound as base oil, coordinate multiple composite additive, its each constituent mass percentage ratio is:
| Component | Content (mass percent) |
| Base oil | Surplus |
| Purification agent | 6.0%～8.0% |

| Kilfoam | 0.001%～0.005% |
| Rust-preventive agent | 0.3%～0.5% |
| Functional agent | 0.3% |
Base oil is that mass ratio 70%～40% poly-alpha olefins and 30%～60% II class base oil are compound.
Purification agent is that alkyl sodium salicylate and 60%～40% high-alkali calcium mahogany sulfonate of mass ratio 40%～60% is compound.
Dispersion agent is diene base succimide.
Antioxidant preservative is the two octyl group basic zinc salt of sulphur phosphorus.
Oxidation inhibitor is that 60%～40% pair of mass ratio, p-di-iso-octyldiphenylamine and 40%～60%2,6-di-t-butyl mixed ester are compound.
Metal passivator is thiadiazoles derivative.
Kilfoam is dimethyl silicone oil.
Rust-preventive agent is that mass ratio 40%～60% petroleum sodium sulfonate and 60%～40% dinonyl naphthalene sulfonate barium are compound.
Functional agent is dialkyldithiocarbamacompositions tungsten.
The canned methane fuelled engine lubricant agent special of purification of the present invention, has good anti-oxidant, digestion resistibility, can effectively prevent the engine oil deterioration by oxidation that high temperature causes or produce settling; Suitable ash content be can keep, engine breathing valve and the prooving of valve seat avoided causing; Corrosion resistance is good, can be effectively in and the acidic substance that produce of corrosives and oil oxidation, reduce the corrosion to engine; It is wear-resistant, antifriction and extreme pressure property outstanding, can meet the continuous high capacity work of methane fuelled engine, is applicable to purify the lubricated of filling methane fuelled engine system.
