摘要

「奈米科技」在近十年來成為各國極力發展之重點科學項目，其迅速發展及所帶來之變革甚至被科學家視為人類社會的第四波工業革命。奈米科技之應用範圍遍及各領域，於磨潤方面亦有許多相關文獻證明其減摩效用。本研究將冶炭奈米科技公司提供之奈米炭添加劑加入原廠引擎用機油，並同時進行單缸直噴式柴油引擎與實車測試兩種實驗以測試奈米炭機油添加劑之可靠度，並將結果與原廠用機油做比較，其中單缸直噴式柴油引擎實驗結果顯示加入奈米炭添加劑之潤滑油較原廠引擎用機油於單缸柴油引擎試驗方面可改善燃料消耗率1.34%，以及降低Smoke濃度值21.08%、NOX濃度值2.78%及HC濃度值7.65%，並使排氣溫度降低1.47%。實車測試結果顯示可提高測試車輛之油耗里程最多8.58%和最低3.46%。由此可證，添加奈米炭機油添加劑可增加汽缸密封性並提高潤滑性能，進而達到節能減排之功效。

In nearly a decade, "Nanotechnology" become a key scientific project developed strongly by most nations. The developing of rapidly Nanotechnology is recognized as the fourth Industrial Revolution by scientists. Nanotechnology is been used at much more industrial field, even can find many reference to prove the effect of reducing fricion in lubrication aspect. we used nano-carbon additive, sponsored by Purplecow Nano Tech, to add in genuine oil in this study. we do experimental trial in single-cylinder DI diesel engine and on-road verification for vehicle to test the reliability of nano-carbon additive. The additive nano-carbon oil compared with genuine oil in experimental result. The results indicated that used additive nano-carbon oil trial in diesel engine could decrease fuel consumption 1.34%, smoke concentration 21.08%, NOX concentration 2.78%, HC concentration 7.65% and also can decrease exhaust temperature 1.47%.The results of on-road verfication for vehicle indicated that used additive nano-carbon oil trial could increase the ratio of kilometers per liter fuel up to 8.58% and the lowest 3.46%.The result verified that nano-carbon additive can increase the cylinder sealing and lubrication performance, achieving the effect of energy saving and reducing emission.
