Abstract: 本研究針對四行程機車,添加奈米二氧化矽於原廠指定使用的機油中,研究機車在運行時的定油門車速(km/h)、燃料消耗率(km/L)、廢氣污染排放以及粒狀汙染物(PM)值做為實驗成果的效益評估。本研究總共試驗了0.5、1.5、2.5、3.5、4.5 wt.%的奈米二氧化矽機油,最後選定磨潤試驗表現較佳的3.5 wt.% 奈米二氧化矽機油。在磨潤試驗中,添加3.5 wt.% 的奈米二氧化矽粉體機油相較無添加奈米二氧化矽的機油,平均降低42.43 % 的磨耗量。在ECE-40行車型態的燃料消耗率(km/L)、爬坡度、定速測試,添加3.5 wt.%奈米二氧化矽的機油,在ECE-40行車型態的燃料消耗率測試平均增加了15.22 %的燃油效耗率,定油門開度測試平均車速增加了10.30 %,爬坡度測試平均車速增加了15.78 %,PM值測試0.3 μm顆粒平均增加了142.48 %、CO平均減少了16.9 %、HC平均減少8.36 %。奈米二氧化矽機油可以提供較佳的潤滑效果,在未來將可以測試複合奈米材料,測試其對於機車燃料消耗率、引擎溫度以及廢氣汙染排放的影響效益。
In this study, nano silica (nano SiO2) was added in to the original named engine oil. It also be experimented on the four-stroke motorcycle. The characteristics of driving-experiment, which includes speed performance, specific fuel consμmption, and the exhaust emissions, such as HC, CO and PM, were estimated as experimental results for the further benefit evaluation. Nano SiO2-engine oil with 0.5, 1.5, 2.5, 3.5 and 4.5 wt.% included have been conducted. It came out that the best tribology experimental came to the engine oil with 3.5 wt.% nano SiO2 added. During the tribology experimental of nano SiO2-engine oil, the engine oil with 3.5 wt.% nano SiO2 added decreased an average of 42.42 % abrasion loss. The fuel consμmption (km/L), climbing capacity, constant velocity testing. The engine oil with 3.5wt.% nano SiO2 added increased the fuel consμmption, speed of fixed throttle testing, climbing capacity and 0.3μm particle with 15.22 %, 10.3 %, 15.78 % and 142.48 %, respectively. Besides, it also decreased the CO and HC with 16.9 % and 8.36 %, respectively. Overall, the engine oil with 3.5 wt.% nano SiO2 added improved the effect of lubricating. In the future, the examination of nano material includes motorcycle fuel consμmption, engine temperature and exhaust emissions would be conducted.
