SBIR Phase I: Engine Combustion Simulator

这项小型企业创新研究（SBIR）第一阶段项目将开发一种名为“发动机燃烧模拟器”的新型软件工具，供汽车工程师更快、更经济地开发新发动机。由于缺乏代表柴油和汽油等真实燃料的燃烧动力学机制，以及在实际时间模拟时间内解决这些大型复杂机制的有效计算技术，汽车发动机研究人员对燃烧动力学建模的使用受到限制。本项目将利用软件和数据库体系结构的最新进展来构建复杂的机制，以及在加速计算方面显示出极好的潜力的数值和符号方法来解决这些限制。这个模拟器的商业价值很高，因为目前有超过5000名汽车工程师为商用发动机建模软件的每个用户支付超过30,000美元的年许可费。这个模拟器带来了一个重要的功能，目前在这些商业软件包中是不提供的。正在开发的新型发动机技术，如HCCI（均质增压压缩点火）发动机，在提高燃油效率和降低排放方面有着巨大的前景。如果成功，该项目将大大加快HCCI发动机的商业化，从而在降低能源使用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.
