柴油发动机尾气颗粒物研究进展

Study on Diesel Particulate

柴油发动机尾气颗粒物的形成是一个复杂的物理化学过程,对其进行研究有助于发动机尾气排放的控制,并对改进发动机和排气管道的结构设置有指导意义.从物理化学特性、实验测量、数值模拟等方面对柴油发动机排放颗粒物研究的最新进展进行了综述,并认为在统一系统中综合考虑各种尺度颗粒的数值模拟工作还需进一步的发展.

The research of diesel emission particulate is summarized in the article in the views of its physical chemistry properties, experimental measurement, numerical simulation and particulate emission standards are discussed. The formation of diesel emission particulate is a complicated physical chemistry progress. The research on it will contribute to the definition for the particulate emission standards and give directions for the design of the engine and exhaust pipe.
