摘　　要：本文研究了直喷式柴油机缸内气体流动,分别考察了涡流、挤流和紊流的变化规律及其相互关系,并以X105和6135柴油机为对象,分析了燃烧室结构参数,压缩余隙和运行工况对气体流动的影响.The gas flow in DI diesel engine cylinders was studied in this paper, the development and variation of swirl, squish and turbulence, and their reletion were respectively researched. X105 and 6135Q high speed diesel engine were thaken as objects. The effects of the chamber geometry, compression clearance and operating condition on the gas flow were also analysed.
