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.

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质压缩点火，但在有限的操作条件下，重复性差。以前的工作使用的“黑箱”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基本的方法来“工程”缸内条件，以实现均匀稀薄零排放燃烧。将研究使用等温过程和高湍流来控制混合和燃烧模式的充气压缩温度控制的使用。化学动力学和计算流体力学建模，验证和现有的实验结果将用于这项工作。
