SBIR Phase I: Reactive Cyclic Induction Marine Diesel Emissions Reduction Monitoring and Delivery System Project

这项小型企业创新研究（SBIR）第一阶段项目的更广泛影响是可能减少船用柴油发动机的有毒氮氧化物（NOx）和有害二氧化碳（CO2）排放。全球约有400万艘柴油动力船只在使用，每年排放约10亿吨二氧化碳和1亿吨氮氧化物。该项目旨在从船用柴油废气中去除至少80%的氮氧化物和30%的二氧化碳，有助于减少温室气体排放和对沿海城市造成健康危害的空气污染。目前还没有可替代的、商业上可行的产品来减少船用柴油发动机的二氧化碳和氮氧化物排放。提出的概念旨在克服竞争技术的缺点，即由于密闭的船机舱内的热量和空间限制而无法实现。该项目可能使船舶制造商能够满足关于发动机排放的新的国际海事法规，并可能为海洋和陆地/车辆减排系统的监测和交付系统的工程提供新的知识。除了环境效益外，这项技术还满足了全球商业需求，并为美国的出口导向型产业创造了高薪就业机会。该项目的目标是开发一种低热电乳化解决方案，以减少船舶柴油废气的排放，特别是减少80%的氮氧化物（NOx），以满足新的国际海事组织（IMO）法规，减少30%的二氧化碳（CO2）。该技术将被整合到燃料处理系统中，该系统可以集成到现有的船用柴油发动机中。该系统将在燃烧循环的适当时间精确地注入改变反应的化学物质，以达到所需的二氧化碳和氮氧化物的减少。该系统还将监测废气流，以确保没有有害的副产品排放到海洋环境中。这项工作将进一步发展对柴油减排的理解，并可能转移到其他车辆和陆地应用。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact of this Small Business Innovation Research (SBIR) Phase I project is the potential reduction of toxic nitrogen oxides (NOx) and harmful carbon dioxide (CO2) emissions from marine diesel engines. There are approximately 4 million diesel-powered craft in use globally, emitting approximately one billion tons of CO2 and 100 million tons of NOx annually. This project seeks to remove at least 80% of the NOx and 30% of the CO2 from marine diesel exhaust, contributing to a reduction in both greenhouse gas emissions and in air pollution that creates health hazards in coastal cities. There is no alternative, commercially-viable product that reduces CO2 and NOx emissions from marine diesel engines. The proposed concept seeks to overcome the disadvantages of competing technologies that are unworkable due to heat and space restraints in a confined boat engine room. The project may enable boat manufacturers to meet new international maritime regulations on engine emissions and may contribute new knowledge related to the engineering of monitoring and delivery systems for marine and land/vehicle emissions reduction systems. In addition to environmental benefits, the technology meets a global commercial demand and creates good paying jobs for an export-oriented US industry.The goal of this project is to develop a low thermal electro-emulsification solution to reduce emissions in marine diesel exhaust, specifically nitrogen oxides (NOx) by 80% to meet the new International Maritime Organization (IMO) regulations and carbon dioxide (CO2) by 30%. The technology will be incorporated into a fuel processing system that can be integrated into existing diesel engines on marine boats. This system will precisely inject reaction-altering chemicals at the proper time in the combustion cycle to reach the desired reduction of CO2 and NOx. The system will also monitor the exhaust stream to ensure no harmful byproducts are discharged into the marine environment. This work will further develop the understanding of diesel emissions reduction and may be transferable to other vehicle and land-based applications.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.
