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性。PHD由英飞凌作为iCASE奖项赞助，将涉及在发动机中存在的温度范围内对仪器进行验证和对润滑油配方进行检查。此外，还将利用振动光谱技术研究油品高温处理的分解机理和产物。润滑油在发动机的高效运转中起着至关重要的作用，润滑油的设计尤为重要，尤其是其热稳定性以及其流动特性随温度和分解程度的变化情况。该项目将使用该设备来监测高温下机油的其他变化，包括洗涤剂性质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
