Internal combustion engines produce gaseous emissions and soot which need to be treated by an aftertreatment system. Catalysts are a key part of these systems and optimising their performance is critical to achieve stringent tailpipe targets across the world. Also, the ability to build accurate aftertreatment models reduces reliance on physical testing of systems when they are at an immature stage of development. In order to improve both attributes, the fundamentals of how a catalyst works (i.e. its mechanism) need to be understood. To achieve this, this project will develop, then use, in-situ methods to perform mechanistic monitoring of catalysts in relevant situations (e.g. three way catalyst oxygen storage behaviour) using the cutting edge equipment available to Cardiff University.

内燃机产生需要通过后处理系统处理的气体排放物和烟灰。催化剂是这些系统的关键部分，优化其性能对于实现全球严格的尾气排放目标至关重要。此外，当系统处于不成熟的开发阶段时，建立精确的后处理模型的能力减少了对系统物理测试的依赖。为了改善这两个属性，需要了解催化剂如何工作的基本原理（即其机制）。为了实现这一目标，该项目将开发，然后使用，现场方法进行相关情况下的催化剂的机械监测（例如，三效催化剂储氧行为）使用尖端设备提供给卡迪夫大学。
