내연기관용 윤활유 성상의 간이한 시험방법에 관한 소고 : 실습선 옥산호의 주기관용을 중심으로 = A Study of the Simplified Testing Method for the Quality of Lubricating Oil for Diesel Engine -By being avail of the marine engine in the training ship "OG-SAN"-

다국어 초록 (Multilingual Abstract)

The lubricating oil supplied for engines frictional parts is very important for the improved efficiency and longevity of engines.
Due to the fact there is no specific testing equipments to determine quality and nature of the lubricating oil presently used for engines and purchaised in the common market, it is possible that great adverse effect could be caused to efficiency and longevity of engines.
A Simple testing method of color, smell, water quotient, specific gravity and chemical reaction was effected, utilizing handy tools and the lubricating oil being used in training ship 'OG-SAN'.
I hope this method not only improved efficiency of engines but also render help to engineers.
