Abstract

[Problem] When burning petroleum fuel for internal combustion engines such as engine oil of gasoline automobiles, exhaust gas containing harmful substances is generated, causing air pollution and the effect of environmental hormones on human health, generation of photochemical smog, carbon dioxide It causes the global environment to deteriorate due to the increase. There is a need for improved combustion technology that is even stricter than conventional standards that should improve the global environment and reduce the impact on human health. Therefore, by keeping the friction loss of the lubricating oil for an internal combustion engine low even after prolonged use, it is possible to improve the combustion efficiency and reduce fuel consumption, and to greatly purify exhaust gas containing harmful substances. To provide a lubricating oil additive.
When a mixed product such as siloxane is used as an additive in a lubricating oil for an internal combustion engine, friction loss is kept low, combustion efficiency is improved, and harmful substances in exhaust gas, such as carbon monoxide and carbon dioxide, are added. It can greatly purify hydrogen and nitrogen oxides, and has a remarkable effect on fuel economy.

[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The additive base material used in the present invention is a borodiphenylsiloxane polymer having boron ( ^B ) introduced into a siloxane skeleton. As such a borodiphenylsiloxane polymer, a commercially available polymer can be used, and examples thereof include Myothermo ^V 940-70 (trade name, manufactured by Ryoden Kasei Corporation).
[0006]
The boro diphenylsiloxane polymers as additives substrate, inorganic ^{Cu, Fe, M n,} cerium oxide, silica, talc is added and mixed oxides such as titanium dioxide. The particle size of these inorganic oxides, for example 0,01～1Myu ^m is desirable.
[0007]
In the present invention, the blending ratio of the borodiphenylsiloxane polymer and the inorganic oxide is, for example, 20 to 100 parts by weight, preferably 30 to 60 parts by weight of the inorganic oxide per 100 parts by weight of the borodiphenylsiloxane polymer.
[0008]
Effects of the embodiment
Hereinafter, the present invention will be further described with reference to examples. For a borodiphenyl siloxane polymer (trade name: Myothermo ^V 940-70, manufactured by Ryoden Kasei Co., Ltd., nonvolatile component 70%, degree of polymerization 5000, viscosity at 20 ° C .: 25 centipoise), inorganic oxide (average particle diameter: 0, 05μ ^m) was blended 30% by weight. By mixing both well, an additive could be prepared. An exhaust gas concentration test of a gasoline engine was performed using the lubricating oil to which this additive was added. The results are shown in Table 1 below.
[Table 1]

From the above table, it can be seen from the above table that the lubricating oil additive of the present invention significantly reduces ^CO and ^HC , which are harmful substances in exhaust gas, and complete increase in ^CO 2 due to increase in ^CO 2, resulting in combustion efficiency. Was confirmed to have improved.
