Significance and Potential of the ResearchThe project is motivated by the need to characterise particulate matter (PM) generated by combustion, because of health concerns, legislation, and the need to have data for model validation.The new technique of Enhanced Thermo-Gravimetric Analysis (ETGA) will side-step concerns about thermal decomposition in conventional Thermo-Gravimetric Analysis (TGA), and provide additional data on the surface area and pore sizes of combustion generated particulate matter (PM).By dividing the filter sample, Enhanced Thermo-Gravimetric Analysis (ETGA), conventional Thermo-Gravimetric Analysis (TGA), X-ray Photoelectron Spectroscopy (XPS) and Raman Spectroscopy (RS) can all be applied to the same sample. This will provide information on the: the elemental carbon/organic carbon ratio, the active surface area and the pore sizes, and the composition and structure of particulate matter from a Spray Guided Direct Injection (SGDI) Engine.CollaborationAn additional purpose of this project is to promote international collaboration by enabling Prof Raine to work at Oxford. The Oxford group have close links with several universities and close contact with Ford, Shell and Jaguar. Data from an SGDI engine have already been supplied to Markus Kraft at Cambridge, who is at the forefront of modelling the formation of combustion generated particulate matter.Planning & ManagementThe manager of the Begbroke Materials Characterisation Facility (Dr Alison Crossley) is very positive about this proposal, and has already been very helpful in developing the ideas for Enhanced Thermo-Gravimetric Analysis (ETGA). Novelty and RiskX-ray Photoelectron Spectroscopy (XPS) and Raman Spectroscopy (RS) are established techniques, albeit ones that are not thought to have been applied to particulate matter from an SGDI engine. In the unlikely event that neither SGDI engine is operational, then emissions can be collected from a port injection gasoline engine (2 SMART Car engines are installed with comprehensive instrumentation). Enhanced Thermo-Gravimetric Analysis (ETGA) may not work in the way envisaged, and if this is the case, then the reasons for the failure would none the less be worth reporting. ResourcesThe main costs are associated with expenses and a salary supplement (for the higher UK living costs) for Prof Raine, but the University of Auckland will continue to pay his salary and the cost of his international travel. The other major cost is for the use of the materials testing facilities, but these will be charged at an internal rate.

研究的意义和潜力本项目的动机是需要对燃烧产生的颗粒物（PM）进行分析，因为健康问题，立法，以及需要有数据进行模型验证。增强热重分析（ETGA）的新技术将避开传统热重分析（TGA）中对热分解的担忧，并提供关于燃烧产生的颗粒物（PM）的表面积和孔径的附加数据。通过划分过滤器样品，增强热重分析（ETGA），常规热重分析（TGA），X射线光电子能谱（XPS）和拉曼能谱（RS）都可以应用于同一样品。这将提供的信息：元素碳/有机碳的比例，活性表面积和孔径，以及组成和结构的颗粒物质从喷雾引导直接喷射（SGDI）Engine.CollaborationAn该项目的另一个目的是促进国际合作，使雷恩教授在牛津大学工作。牛津集团与几所大学有着密切的联系，并与福特、壳牌和捷豹有着密切的联系。来自SGDI发动机的数据已经提供给剑桥的Markus Kraft，他在模拟燃烧产生的颗粒物的形成方面处于最前沿。规划与管理Begbroke材料表征设施的经理（Alison Crossley博士）对这一提议非常积极，并且已经在开发增强热重分析（ETGA）的想法方面提供了非常大的帮助。新奇和风险X射线光电子能谱（XPS）和拉曼能谱（RS）是已建立的技术，尽管这些技术被认为尚未应用于SGDI发动机的颗粒物。如果两台SGDI发动机都不工作，则可以从进气道喷射汽油发动机收集排放物（2台SMART Car发动机安装有综合仪器）。增强型热重分析（ETGA）可能不会以预期的方式工作，如果是这种情况，那么失败的原因仍然值得报告。资源主要费用与雷恩教授的费用和工资补贴（用于较高的英国生活费用）有关，但奥克兰大学将继续支付他的工资和国际旅行费用。另一项主要费用是使用物料测试设施的费用，但这些费用将按内部收费率收取。
