Multi Fuel, Multi-level Environmental Development Of The Internal Combustion Engine Oil

The dissertation mainly describes about development histories, present status and trend of automobile engine lube oils, introduces the development of automobile engine oil with the technology of automobile engine develops rapidly, and vehicle internal-combustion engine oil keep on satisfying the needs of high-power, heavy-duty and high-speed. R&D of modern lubricating oils are based on three fields - base stock, lubricating additives and analysis & evaluation. The Level of them reflects the level of lubricating oils trade in their country directly. In order to made good use of the existing energy sources and exploit the new sources, fuel which automobile use have to develop diversify. The automobile engine oil which vehicle use have to develop diversely too, and give rise to muti-rotor engine, ceramic internal-combustion, extraordinary engine (otherwise jet), and another new engine technology of electric spray, fume compressor of turbine, environment protection consciousness strengthen and strict emission standard raising promote to the change of technology of engine oils.For the sake of large-size motorcade and working on large engineering machines' needs, muti-fuel & grade, all-weather, environment protection automobile engine oil are being researched. R&D start with two fields which are base oil and additives. In the respect of base oil, the base oil mainly hydrogenation for maximum quality and purity. This dissertation describes the fundamental theory of hydrogenation processed base oil, including technological process, technological features and standard. Besides, it describes process of deal with plant oils are fit for automobile engine oils, pass biodegradation test and choice proportion of them. On the other hand, it introduces the function of additives for automobile engine in the respect of fundamental theory. The key of this research is relational capacity and compound proportion to main contradiction of reducing ashes and high-basicity value, technology and application technological process of compare foreign company with domestic company. Therefore, the developing lubricating oil may fit for all-weather, muti-fuel & structure automobile engine, and it is a kind of environmental protection & energy conservation, green lube lube oil with pollution, low emission, long life.In addition, the dissertation introduces how to organize the developing oil analysis & evaluation, road test and vehicle using situation, and describes how to analysis oil sample. Meanwhile, it describes the developing oil's industrialization technological process and the main mix equipment.This research is Guangxi Science & Technology Departmant, Nanning Science & Technology Department and Nanning Economy & Trade Committee had established scientific research project in the developing oil one after another in 2002, and has acquired the authentication of Hi-Tech Production and National invention Patent.
