This Small Business Innovation Research (SBIR) Phase II project will prototype, characterize, and verify performance merits and the commercial viability of an Adaptive Dual-Fuel (ADF) Injector. Diesel engines are 30~40% more efficient than port-injected gasoline, spark-ignited engines. Gasoline and E85 fuels are among the most widely available fuels, but are mostly used on spark-ignition gasoline engines with much lower thermal efficiency than diesel engines. The key innovation of the ADF injector enables direct-injections of both gasoline/E85 and diesel fuel selectively on-demand from a single injector. The ADF injector can enable advanced combustion modes that have demonstrated simultaneous reduction of NOx and Particulate Matter (PM) emissions and improved engine efficiency through advanced low temperature combustion. The advanced combustion mode enabled by the ADF injector can improve the thermal efficiency of gasoline/E85 engines by approximately 30~40% by using gasoline and/or E85 fuels in a compression ignition combustion mode. The adaptive dual-fuel injector also provides flexibility for enabling engines to run on either pure diesel, gasoline-diesel, or E85-diesel dual fuels. The Phase II work includes prototyping, spray visualization imaging and laser based measurements, computational optimization, and single-cylinder engine combustion testing to demonstrate the commercial viability of the proposed ADF injector. The broader/commercial impacts of this project pertain to significant benefits for energy security and environmental protection. The potential customers include engine OEMs and auto makers. This project will significantly benefit US consumers through fuel cost saving, enable low cost methods to meet the new CAFE standards, and benefit the US economy by expanding the ?green? manufacturing base. The dual fuel injector, developed and analyzed in this work, provides new capabilities, which can enable transformative combustion methods for ultra-high efficiency, clean combustion. The industry-university collaborative engineering research directly support graduate student research and will train and educate the workforce of the future, providing them with the knowledge and skills needed to address the challenges of energy utilization. The research and development efforts, which focus on a critical problem of global importance, will be widely disseminated to engine designers, OEMs, and researchers, while the next generation of engineers is being trained.

这项小型企业创新研究（SBIR）II期项目将原型，表征和验证性能优点以及自适应双燃料（ADF）注射器的商业可行性。柴油发动机的效率比注射端口的汽油，火花点燃发动机高30〜40％。汽油和E85燃料是最广泛的燃料之一，但主要用于火花点击汽油发动机，其热效率比柴油发动机低得多。 ADF喷油器的关键创新可以直接从单个喷油器中直接注射汽油/E85和柴油燃料。 ADF喷油器可以实现高级燃烧模式，这些模式同时降低了NOX和颗粒物（PM）排放，并通过晚期低温燃烧提高了发动机效率。 ADF注射器启用的高级燃烧模式可以通过在压缩点火燃烧模式下使用汽油和/或E85燃料，将汽油/E85发动机的热效率提高约30〜40％。自适应双燃料喷油器还为使发动机在纯柴油，汽油柴油机或E85柴油双燃料上运行提供了灵活性。第二阶段的工作包括原型制作，喷雾可视化成像和基于激光的测量，计算优化以及单缸发动机燃烧测试，以证明拟议的ADF注射器的商业生存能力。该项目的更广泛/商业影响与能源安全和环境保护的重要好处有关。潜在客户包括引擎OEM和汽车制造商。该项目将通过节省燃料成本，使低成本方法能够满足新的CAFE标准并通过扩展“绿色”来使美国经济受益？制造基地。在这项工作中开发和分析的双燃料喷油器提供了新的功能，可以实现转化燃烧方法，以实现超高效率，清洁燃烧。行业 - 大学合作工程研究直接支持研究生研究，并将培训和教育未来的劳动力，为他们提供应对能源利用挑战所需的知识和技能。研究与发展的工作重点是全球重要性的关键问题，将广泛传播到发动机设计师，OEM和研究人员，而下一代工程师正在接受培训。
