摘　　要：通过CFD软件FIRE对某型柴油机的缸内流动过程进行了数值模拟,通过计算得到了气流在缸内的分布情况、缸压值以及涡流比,并对燃油的雾化能力进行了评估。This article had a numerical simulation on in-cylinder flow of a certain diesel engine by using CFD software--FIRE. Some results were calculated, such as gas flow in-cylinder distribution, cylinder pressure and mean swirl number. At last fuel evaporation was evaluated.

关 键 词：缸内流动 涡流比 雾化
