 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Study on Lubricating Oil Characteristics Using Viscosity Index) ผู้เขียน:นายธีระยุทธ สุวรรณประทีป, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe objective of this research is to investigate the characteristics of lubricating oil sold in the market by using viscosity index. The lubricating oil of both single grade and multigrade of some trade names for gasoline engines and one without trade name are used in the test and the viscosity index is determined for each type. The test shows that every type of lubricating oil with trade name has viscosity index of more than 100, the highest standard value, and the multigrade oil has more viscosity index than the single grade oil. The oil without trade name has viscosity index rather low and therefore is not suitable for lubrication over a wide range of working temperature, such as in gasoline engines. |
