发动机气缸内的紊流特性

The Turbulence Characteristics in the Cylinder of an Engine

发动机气缸内的紊流运动对燃烧过程有重要影响。有效地组织发动机气缸内的紊流运动,已成为现代发动机改善经济性和控制排污的重要方法。近年来国内外学者对它进行了许多研究。本文论述了这方面的研究结果,较系统地分析了压缩上止点附近,影响紊流宏观空间尺度的因素。

The turbulence movement of an engine cylinder is very important to the combustion process, if we can make it under good control we can economize the engine and improve the exhaustion. This paper presents a systematic analysis of the factors which affect the turbulence movement in an engine.
