项目摘要

The broader impact/ commercial potential of this Small Business Innovation Research (SBIR) project includes reducing emission of Diesel engines' toxic nitrogen oxides (NOx) in challengingly low temperature exhaust operations, while eliminating damaging urea deposits saving warranty costs for vehicle manufacturers, saving fuel, reducing greenhouse gases CO2 and N2O as well as particulate matter, while potentially enabling downsizing the complex and costly diesel emission control systems. The novel technology developed in this SBIR project may be configured for retrofitting existing diesel platforms. Nitrogen oxides pose risks to human respiratory and pulmonary systems, are associated with forming ground level ozone, photochemical oxidants, acid rain and fine particles, amongst a variety of their detriments, and their emission is therefore regulated. Our concept, when successful, will therefore make available a broad value proposition to the society, the environment and to the mobility industry. Finally, the insights developed into its gas phase reactions may have applications in other branches of science and technology.This SBIR Phase II project proposes to resolve a currently unmet need in mitigating emission of toxic nitrogen oxides (NOx) from diesel engines, especially in low exhaust temperatures such as when the vehicle operates in stop-and-go, in local delivery or when idles its engine. The goal of this project is to develop a low cost, easy-to-fit and simple-to-integrate novel technology enabling low temperature Diesel NOx reduction. Continuing our successful Phase I research results, in this Phase II project more advanced prototypes will be developed and tested in low-temperature exhaust conditions, demonstrating rapid reduction of NOx on a commercially-available Selective Catalytic Reduction (SCR) catalyst, while evaluating the impact on lowering greenhouse gases CO2 and N2O. High fidelity computer simulations will be heavily utilized to further our understanding of underlying mechanisms such as the gas-phase reactions as well as to accelerate the development path. The project outcome is expected to alleviate a remaining challenge in Diesel emission control and to be rapidly welcome by the Diesel engine and vehicle industry.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）项目的更广泛的影响/商业潜力包括减少柴油发动机在挑战性的低温排气运营中的毒性氮氧化物（NOX）的排放，同时消除损坏的损坏，同时节省损坏的保修，以节省车辆制造商，以节省燃料，并减少燃料的成本，并降低燃油量，并降低了co2和N2O的销量，并降低了零件的销量，并构成了颗粒物的销量。控制系统。在此SBIR项目中开发的新技术可能是为改造现有柴油平台的配置。氮氧化物对人的呼吸系统和肺部系统构成风险，与形成地面臭氧，光化学氧化剂，酸雨和细颗粒的形成，在各种损害中，它们的发射受到调节。因此，我们的概念在成功时将为社会，环境和流动性行业提供广泛的价值主张。最后，在其气相反应中发展的见解可能在其他科学和技术分支中都有应用。该SBIR II期项目建议解决当前未满足的需求，以减轻柴油发动机的有毒氮氧化物（NOX）的排放，尤其是在低排气温度下，尤其是在诸如车辆在当地交付或当地交付时运行时的发动机或何时在其发动机中运行时。该项目的目的是开发低成本，易于构建和易于综合的新技术，以降低低温柴油NOX。继续我们成功的I期研究结果，在此II期项目中，将在低温排气条件下开发和测试更先进的原型，这表明NOX快速减少在商业上可用的选择性催化减少（SCR）催化剂上，同时评估对降低温室气体CO2和N2O的影响。高保真计算机模拟将大量利用我们对诸如气相反应等基本机制以及加速发展路径等基本机制的理解。预计该项目的结果将减轻柴油排放控制中的剩余挑战，并受到柴油发动机和车辆行业的迅速欢迎。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛影响的评估标准来评估值得支持的。
