| dc.description.abstract | The characteristic of a lubricant is very important when it is used under severe running condition. Especially on diesel engines the better lubrication performance is required because of the extreme condition such as high temperature and pressure by combustion process in a cylinder. Many researches work for improving a boundary lubrication performance have been executed by using solid lubricant but this general lubricant has not been applied to engine due to the extreme condition of high temperature and pressure in a cylinder. Recently, the solid lubricant which contained a copper nickel alloy has been introduced and studied. In this study, the author investigated the effects of lubricant which contains the copper nickel alloy nano-powder on a diesel engine performance. The results were manifested to show the increase of maximum torque, and the decrease of cylinder pressure, exhaust gas temperature, scavenging air temperature, CO emission according to running time lapse at various speed and torque on a diesel engine. It was assured that the lubricant which contains the copper nickel alloy nano-powder decreases friction and wear, and simultaneously increases the sealing effect in a cylinder on diesel engines. | - |
