Thermo-Optical Diagnostics for Combustion Engine Development

内燃机对环境和健康的既定影响促使开发了几种发动机操作和燃料供给策略，旨在减少对进口燃料的依赖、燃料消耗和有毒物质的排放。其中包括先进的柴油喷射策略和通过双燃料燃烧模式有效利用北美重要的天然气储量。虽然这些技术具有重大的前景，但仍然需要对基本的燃烧和排放形成过程有基本的了解。这项工作将考虑这些过程中使用的光学可访问的发动机，开发和评估一种新的热光诊断技术，以提供更高的保真度在真实的（即非光学）发动机的燃烧特性，并开发数值工具描述的燃烧和排放形成过程。所有这些成果将为加拿大汽车工业提供开发先进内燃机的知识和工具。此外，它将有助于加强加拿大在天然气发动机技术开发方面的国际领导地位。除了这些技术贡献外，这项研究还将培训4-6名高素质人员，为他们提供发动机开发、燃烧和排放以及相关诊断技术方面的宝贵技能，进一步加强加拿大在这些领域的劳动力。

The established environmental and health impacts of internal combustion engines has prompted the development of several engine operating and fuelling strategies aimed at reducing the reliance on imported fuels, fuel consumption, and the emission of toxic substances. Included in these are advanced diesel injection strategies and the effective use of the significant North American natural gas reserves through dual-fuel combustion modes. While these technologies hold significant promise, a fundamental understanding of the underlying combustion and emission formation processes is still needed. This work will consider these processes using an optically accessible engine, develop and evaluate a novel thermo-optical diagnostic technique to provide higher fidelity combustion characterization in real (i.e. non-optical) engines, and develop numerical tools describing the combustion and emission formation process. All of these outcomes will provide the Canadian automotive industry the knowledge and tools to develop advanced internal combustion engines. Furthermore, it will help strengthen Canada's international leadership in the development of technologies for natural gas fuelled engines. In addition to these technical contributions, this research will train 4-6 highly qualified personnel, providing them with valuable skills in engine development, combustion and emissions, and associated diagnostic techniques, further strengthening Canada's workforce in these fields.
