The lubricating agent composition comprises a cleaning agent, a dispersing agent, an antioxidant, an antioxygen preservative agent, an antirust agent, an antifoam agent and an accessory ingredient. The lubricating agent composition can be directly applied to a lubricating system of the low heat rejection diesel engine, has the advantages of favorable shearing resistance, thermal oxidation stability, low volatibility, high soot dispersion property, cooling property, sealing property, cleaning property, anti-rust property, low-temperature fluidity, stable alkali number retainability and acid neutralization capability, and is capable of reducing hydrocarbon and oxynitride emission.
Description
Technical field
The invention belongs to the lubricating oil field of engine, particularly low heat rejection diesel lubricant compositions.
Background technology
Low heat rejection diesel is different from traditional liquid-cooling system, and the power loss passed in heat-eliminating medium is converted into Crankshaft motion output work, to reduce the oil consumption of diesel motor.Low heat rejection engine temperature of combustion is higher, improve efficiency of combustion, can be burnt inferior fuel, this not only can make fuel economy obtain basic improvement, also can cancel water coolant, thermostat, scatterer, water pump, cooling fan and relevant pipeline and clip simultaneously, simplified construction, weight reduction, improves unit mass output rating.
Low heat rejection engine is that burning chamber of diesel engine and exhaust passage adopt the heat insulation partial loss reducing or eliminate diesel engine working cycle as far as possible.According to the first law of thermodynamics: reduce the useful work that the heat entered in heat-eliminating medium can increase piston; , can be obtained by the second law of thermodynamics, diesel engine at high temperature carries out burning to acting advantageously meanwhile.Because temperature raises, the immutableness of thermal processing reduces.In addition, reduce thermosteresis and also make exhaust enthalpy increase, this just makes energy can be used to promote combined turbine and then help the thermo-efficiency improving whole system.Improve working temperature, will high-temperature material be used.Therefore the structural ceramics such as silicon nitride and silicon carbide class material causes the attention of height.Be faced with the high temperature friction lubrication problem between piston and cylinder sleeve at low heat rejection engine, lubricant cannot meet the requirement of high temperature lubricating in the past.Therefore the synthetic fluid lubricant of necessary development of new advanced person.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low heat rejection diesel lubricant compositions with good shear resistant, thermal oxidation stability, low volatility, high dispersive soot, cooling, stopping property, cleaning, rust-preventing characteristic, low-temperature fluidity, stable base number retentivity, acid neutralization capacity, minimizing hydrocarbon polymer and oxynitride discharge.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
Low heat rejection diesel lubricant compositions, adopt oil based on polyphenylene oxide, coordinate multiple additives, its each component and mass percent thereof are:
