摘要
新型二冲程微型摆式内燃机预压缩室的作用是对进入腔内的新鲜充量进行预压缩,使其在进入工作腔内有一定的预压力,从而达到充分的混合,以保证燃烧的适时性和充分性,以及提高扫气效率。本文通过运用FLUENT中的动网格模型对其在预压缩过程中的流场进行了分析。获取了场内压力和流线的分布,以验证预压缩室能否达到其工作要求。
The novel two-stroke micro free swing piston engine＇s precompressed chamber is to precommpress the fresh charge, which will enter the combustion chamber with expected pressure, so that the fuel will be burn timely and completely. Dynamic meshes model of the CFD software FLUENT is used in this paper. Through the analysis of the fluid field of the novel two-stroke micro free swing piston engine＇s precompressed chamber, we obtained the necessary data and figure about static pressure and path lines. So the precompressed chamberg function will be validated.
