Abstract
The invention relates to the technical field of lubricating oil, in particular to lubricating oil for diesel engines. The lubricating oil comprises, by weight, 60-80 parts of base oil, 20-30 parts of surfactants, 3-9 parts of antioxidants, 2-6 parts of polytetrafluoroethylene, 5-8 parts of cleaning agents and 6-12 parts of corrosion inhibitors. The lubricating oil has the advantages that component compatibility is high; the lubricating oil does not contain metal cleaning agents and has low ash content, high cleaning dispersity is achieved, and high cleanness of pistons of the engines can be kept; oxidation and corrosion resistance and shear stability are high, and proper viscosity of the oil can be kept when the engines are in low-temperature, high-temperature or high-shear environments; abrasion resistance is high, DPF (diesel particulate filter) blocking is prevented, and valve train abrasion is reduced; environment burdens are reduced.
Description
Technical field
The present invention relates to technical field of lubricating oil, particularly a kind of diesel engine oil.
Background technology
Diesel particulate filter (hereinafter referred to as DPF) is considered to the effective ways removing particulate matter (hereinafter referred to as PM) in diesel exhaust gas, but due to the existence of metal ingredient in used engine oil, they may live through the blocking of filter.Such as, the known grey branch derived from diesel engine oil accumulates in DPF, and this will cause PM elimination efficiency to reduce and the DPF lost of life, therefore thinks and in other words namely must reduce ash oontent by the sulfated ash that must reduce in diesel engine oil.
This means engine oil and particularly diesel engine oil experienced by the history of change due to the change of fuel.Such as, the topsoil that the particulate matter, carbon monoxide and the NOx emission that cause due to emission gases cause is a problem, and sulphur content especially in diesel oil 10 years or more years in the past, is reduced to rapidly is not more than 10ppm by being not more than 500ppm.Due to these emission gases counter-measures, the finishing apparatus being referred to as DPF is installed in diesel engine.But in order to prevent DPF from blocking, create the demand to low ash content engine oil.
In addition, for sulphur content, it is known that there is harmful effect to piston cleanliness and wearing and tearing in the sulfuric acid that burning forms sulfuric acid and so formation, with it is known that phosphorus in engine oil is the poisonous substance of exhaust gas purifying catalyst, therefore at present it is envisaged that the trend being conducive to the engine oil of low ash content/low-phosphorous/low-sulfur (being called " low SAPS ") can become more and more stronger.This require matched with diesel engine use to diesel lubrication oil peace and quiet, dispersion, anti-oxidant, to resistance to wear etc. in requirement more harsh.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of diesel engine oil, it does not comprise metal detergent and has lower ash oontent, keep fabulous engine piston spatter property simultaneously, prevent DPF to block and reduce valve train wearing and tearing, thus reducing environmental pressure.
For achieving the above object, the present invention adopts following technical scheme:
A kind of diesel engine oil, be made up of the raw material of following weight part:
Base oil of the present invention is the I or II class lubricating oil base oil by API classification.
Tensio-active agent of the present invention is the mixture of 10 ~ 20 part by weight of alkylglycoside, 5 ~ 10 weight part tea saponins and 15 ~ 25 parts sulfuric acid Viscotrol C.Tensio-active agent has good dispersion and emulsification function, ensures the stability of lubricating oil, also has good lubrication.Wherein, alkyl glycoside is synthesized by renewable resources natural fat alcohol and glucose, it is the more comprehensive new non-ionic surfactants of a kind of performance, it has the characteristic of conventional nonionic and anion surfactant concurrently, there is high surface, good ecological security and intermiscibility, be internationally recognized first-selection " green " functional surfactant, add the lubricity between diesel oil molecules; Tea saponin is a kind of non-ionic type pure natural tensio-active agent of excellent property, has stronger emulsification, dispersion and wetting action, the environmental protection of pure natural, environmentally safe; Sulfated castor oil is anion surfactant, water soluble, has the multiple performances such as wetting, infiltration, emulsification, dispersion, levelling, hydrotropy, lubrication, makes lubricating oil have good oilness and stability.
Antioxidant of the present invention is the mixture of the p-di-iso-octyldiphenylamine of 12 ~ 22 weight part and the tertiary Ding-4-methylphenol of 20 ~ 30 weight parts 2,6-bis-.Add antioxidant, the usage period of diesel oil can be extended, be convenient to preserve.
Purification agent of the present invention is the mixture of the polyetheramine of 10 ~ 20 weight part PIBA and 15 ~ 25 weight parts.Use purification agent, can removing carbon, keep fabulous engine piston spatter property, prevent DPF to block and reduce valve train wearing and tearing, emissions reduction, promoting environmental protection.
Corrosion inhibitor of the present invention is the mixture of the tertiary Ji Ding phenol of 12 ~ 22 weight part 2,4-bis-and 14 ~ 24 weight part methyl isobutyrates.The many metal protections of material to engine fuel system are had in diesel oil; copper, iron, aluminium, lead, magnesium and their many alloys can be corroded; diesel oil can absorb the moisture in air simultaneously; add corrosion inhibitor and metallic surface strong effect, produce chemistry and physisorption, form good protective membrane; isolate the contact of corrosive deposit and metalwork to a certain extent; reach the object suppressing corrosion, protection engine fuel system, increases the service life.
The particle diameter of tetrafluoroethylene of the present invention is 10 ~ 50nm.Tetrafluoroethylene strengthens oilness, and between two surface of friction, put into tetrafluoroethylene, its shearing resistance is very little, slightly external force, intermolecularly will produce slippage, like this external friction between two surface of friction be changed into the internal friction between solid lubrication agent molecule, play good lubrication, Castor Oil tube wall and engine wall, reduce bavin oil drag, ensure that diesel oil conveying is carried out smoothly, keep continuing overheavy firing, ensure the normal use of diesel oil, engine fuel 3 ~ 6% can also be saved.The resistance to abrasion of lubricating oil can be improved simultaneously, prevent DPF to block and reduce valve train wearing and tearing.
Preferably, diesel engine oil of the present invention, be made up of the raw material of following weight part:
Beneficial effect of the present invention is:
The each component compatibility of diesel engine oil of the present invention is good, it does not comprise metal detergent and has lower ash oontent, there is good detergent-dispersant performance, fabulous engine piston spatter property can be kept, antioxygen corrodibility and shear stability better, ensure that oil product still has suitable viscosity under engine low temperature, high temperature, high shear environment, have good resistance to abrasion, prevent DPF to block and reduce valve train wearing and tearing, thus reducing environmental pressure.
