Tribology is central to future developments in transport and energy efficient systems. The reduction in fuel consumption and control of emissions and in modern combustion engine components made of lightweight alloys require fundamental understanding of tribological processes at all scales. The proposed program will identify the micromechanisms associated with lightweight internal combustion engines, with an emphasis on determining the causes of friction losses and will advance a methodology to increase engine efficiency by minimizing these losses in critical components including pumps or rockers or cams etc. The research will encompass the following areas; i) the development of new testing methods to simulate wear and friction mechanisms that occur in internal combustion engines; ii) the delineation of wear, adhesion and friction micromechanisms from microstructural and atomistic points of view; iii) the design of interfaces that reduce friction in powertrain components based on the results of experimental and computational work.

摩擦学是未来交通运输和节能系统发展的核心。为了减少燃料消耗和控制排放，以及在由轻质合金制成的现代内燃机部件中，需要对所有级别的摩擦学过程有基本的了解。拟议的计划将确定与轻型内燃机相关的微观机制，重点是确定摩擦损失的原因，并将推进一种方法，通过将泵、摇杆或凸轮等关键部件的这些损失降至最低来提高发动机效率。这项研究将包括以下领域：i)开发新的测试方法来模拟内燃机中发生的磨损和摩擦机制；ii)从微观结构和原子角度描述磨损、粘着和摩擦微观机制；iii)基于实验和计算工作的结果设计动力总成部件中减少摩擦的界面。
