Abstract

Carbon nanotubes (CNTs) are well-known nanomaterials with many excellent properties such as high hardness, high strength, and excellent thermal conductivity. Owing to their very high thermal conductivity (2000 W/m.K compared to thermal conductivity of Ag 419 W/m.K), CNTs become ones of the most suitable nano additives for fabricating the lubricating oils in order to increase the thermal conductivity of lubricating oils, to enhance the efficiency of heat dissipation for the engine, and to improve the performance efficiency of engine. In this work, we present the obtained results on application of the CNTs in lubricating oils for some engines. The results showed that with the addition of CNTs, the thermal conductivity of lubricating oils increase about 15%, this helps improve the efficiency of heat dissipation for the engine. Experimental results show that when using the lubricating oils containing carbon nanotubes, the temperature of engine dropped about 10°C, fuel saving was upto 15% and longevity of lubricating oil increased upto 20,000 km.

发动机用碳纳米管润滑油

碳纳米管(Carbon nanotubes, CNTs)是一种众所周知的纳米材料，具有高硬度、高强度和优异的导热性。由于其非常高的导热系数(2000 W/m)。(与导热系数Ag 419 W/m.K相比)，CNTs可以增加润滑油的导热系数，提高发动机的散热效率，提高发动机的性能效率，是最适合用于制造润滑油的纳米添加剂之一。在这项工作中，我们介绍了碳纳米管在某些发动机润滑油中的应用所获得的结果。结果表明，添加CNTs后，润滑油的导热系数提高了约15%，有助于提高发动机的散热效率。实验结果表明，使用含碳纳米管的润滑油时，发动机温度下降约10℃，节油达15%，润滑油寿命提高至2万公里。
