SBIR Phase I: Engine Combustion Simulator

这个小型企业创新研究(SBIR)第一阶段项目将为一种名为发动机燃烧模拟器的新型软件工具制作原型，供汽车工程师使用，以更快、更具成本效益地开发新发动机。由于缺乏代表柴油和汽油等真实燃料的燃烧动力学机理，以及在实际时间模拟时间内求解这些大型复杂机理的有效计算技术，汽车发动机研究人员对燃烧动力学模型的使用一直受到限制。该项目将通过利用软件和数据库体系结构方面的最新进展来解决这些限制，以建立复杂的机制，并利用已显示出极有潜力加快计算的数值和符号方法。该模拟器的商业价值很高，因为目前有超过5,000名汽车工程师为每个用户支付超过30,000美元的年度许可费，以购买商用发动机建模软件。这个模拟器提供了一个重要的功能，这是目前在这些商业包中无法提供的。正在开发的新发动机技术，如HCCI(均质充气压燃)发动机，在提高燃油效率和降低排放方面有着巨大的希望。如果成功，该项目可以显著加快HCCI发动机的商业化进程，从而在降低能源消耗和排放方面产生重要的社会影响。

This Small Business Innovation Research (SBIR) Phase I project will prototype a novel software tool called the Engine Combustion Simulator for use by automotive engineers to more quickly and cost-effectively develop new engines. The use of combustion kinetic modeling by automotive engine researchers has been limited due to a lack of combustion kinetic mechanisms representing real fuels like diesel and gasoline, and efficient computational technologies to solve these large complex mechanisms within a practical time simulation time. This project will address these limitations by utilizing recent advances in software and database architecture for building complex mechanisms, and in numerical and symbolic methodologies that have shown excellent potential to speed up computation. The commercial value of this Simulator is high as there are currently over 5,000 automotive engineers paying over $30,000 per user in an annual license fee for commercially available engine modeling software. This Simulator brings an important capability that is currently not available in these commercial packages. New engine technologies under development such as the HCCI (homogeneous charged compression ignition) engine, hold a great promise in higher fuel efficiency and lowering emissions. If successful, this project can significantly speed up the commercialization of the HCCI engine and hence make an important societal impact in lowering the energy usage and emissions.
