Title:
LUBRICANT COMPOSITION FOR TESTING THE PERFORMANCE OF INTERNAL COMBUSTION ENGINE PARTS, AND METHOD OF PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/1998/059022
Kind Code:
A1
Abstract:
A lubricant composition for testing the performance of internal combustion engine parts etc., produced by dispersing carbon black into a lubricating oil in such a manner that the volume weighted average diameter of the aggregate of the carbon block is 0.05 to 0.45 $g(m)m, and a method of producing a lubricant composition for testing the performance of internal combustion engine parts etc., characterized by dispersing carbon black into a lubricating oil in such a manner that the volume weighted average diameter of the aggregate of the carbon black is 0.05 to 0.45 $g(m)m by using a dispersing machine using a dispersion medium. This method can stably supply a large quantity of the lubricant composition having properties approximate to the waste oil of actual cars and stable qualities.
