Determination of the Thermophysical Properties of Engine Lubricants

本项目旨在开发和使用一种新的技术来测量发动机润滑油的高温热物理性能。博士学位由Infineum作为iCASE奖项赞助，将涉及在发动机当前温度范围内验证仪表和检查润滑油配方。此外，还将利用振动光谱学对油的高温分解机理和产物进行研究。润滑油在发动机的高效运行中起着至关重要的作用，其设计非常重要，特别是其热稳定性以及其流动特性如何随温度和分解范围的变化。该项目将使用该设备监测油在高温下的其他变化，包括洗涤剂性能的变化和形成的任何颗粒的性质

This project aims to develop and use a new technique to measure the high temperature thermophysical properties of engine lubricants. The PhD is sponsored by Infineum as an iCASE award and will involve the validation of the instrumentation and the examination of lubricant formulations over the range of temperatures present in the engine. In addition, the decomposition mechanism and products from the high temperature treatment of the oils will be studied using vibrational spectroscopy. Lubricants play a critical role in the efficient running of engines and their design is of significant importance particularly their thermal stability and how their flow properties change with temperature and extend of decomposition. The project will use the device to monitor other changes in the oils at elevated temperature including changes in the detergent properties and the nature of any particulates formed
