A novel approach to zero emission combustion for ultra-high efficiency internal combustion engines

如果缸内条件得到精确控制，发动机可以实现零排放。其他研究人员已经证明了均匀压缩点火，但在有限的操作条件下，重复性差。以前的工作使用了“黑匣子”的方法很少或根本没有考虑燃烧过程的基本原理。该项目旨在开发一种“工程”汽缸内条件的基本方法，以实现均匀的精益零排放燃烧。将研究利用等温过程和高湍流的电荷压缩温度控制来控制混合和燃烧模式。化学动力学和CFD建模，通过现有的实验结果验证和告知，将用于这项工作。

Zero emissions can be achieved in an engine if the in-cylinder conditions are precisely controlled. Homogenous compression ignition has been demonstrated by other researchers but at limited operating conditions and with poor repeatability. The previous work used the 'black box' approach with little or no consideration of the fundamentals of the combustion process. This project aims at developing a fundamental approach to 'engineering' the in-cylinder conditions to achieve homogenous lean zero emission combustion. The use of charge compression temperature control using isothermal processes and high turbulence to control mixing and combustion mode will be investigated. Chemical kinetic and CFD modelling, validated and informed by existing experimental results will be used for this work.
