A Systems Approach to Ultra-Clean and Ultra-Efficient Internal Combustion Engines

从机械工程的角度来看，汽油发动机是运输和发电系统的扭矩产生器。传统上，机械工程师研究将发动机排气AFR维持在14.1并避免发动机失火的燃油控制解决方案。从化学工程学的角度来看，汽油发动机是为化学反应装置(废气后处理系统)提供燃料的排放物产生者。该研究项目寻求一种革命性的方法，用于稀薄燃烧操作的发动机加油控制器设计和排气后处理设计，并通过非线性控制实现发动机与排气后处理系统的最佳集成。总的来说，这些努力将产生最大的燃油经济性，同时确保尾气排放为零。运输系统动力总成的这些进步将是机械工程师和化学工程师密切合作的结果。此外，这项研究将推动通过跨学科教育促进的跨学科研究项目。这种新的研究生教育模式建立在交叉培训的基础上，让ME学生参加ChemE课程，让ChemE学生参加ME课程。我们的方法让机械工程专业的学生选修化学、反应工程和催化课程，以便将产生放热的化学反应整合到他们的传热学知识库中。化工工程师将进行MECE系统建模(集总参数建模)、鲁棒控制和系统诊断，最终将产生21世纪超清洁、超高效的变电工程。这些工程师在全国范围内的影响将导致减少对外国人的依赖，并将对环境产生积极影响。预计这项工作将带来高效的下一代发动机，这将是环保的，因为燃烧活动将被用来净化空气。

Gasoline engines from a mechanical engineering point-of-view are torque producers fortransportation and power generating systems. Traditionally, mechanical engineers investigate fuelingcontrol solutions that maintain the engine exhaust AFR at 14.1 and avoid engine misfires. From achemical engineering view point, gasoline engines are emissions producers that feed chemicalreactors (exhaust aftertreatment systems). This research project seeks a revolutionary approach toengine fueling controller design and exhaust aftertreatment design for lean burn operations, and theoptimal integration of the engine with the exhaust aftertreatment system through nonlinear control.Collectively these efforts will produce maximal fuel economy while ensuring zero tailpipe emissions.These step advancements in transportation system powertrains will be the results of a closecollaboration between mechanical engineers and chemical engineers. Moreover, this research willadvance an interdisciplinary research project facilitated through a cross-disciplinary education. Thisnew graduate education model builds on cross-training by having ME students take ChemE courseand ChemE students taking ME courses. Our approach has mechanical engineering students takingChemE reaction engineering and catalysis courses so that chemical reactions producing exothermscan be integrated into their heat transfer knowledge base. The chemical engineers will take MECEsystems modeling (lumped parameter modeling), robust controls and systems diagnostics.Ultimately, the 21st century ultra-clean and ultra-efficient power transformation engineer will beproduced. The national impact of these engineers will lead to a decrease in dependence on foreignoil and will have a positive impact on the environment. It is anticipated that this work will lead toultra-efficient next generation engines that will be environmentally friendly since the combustionevent will be used to clean the air.
