摘要
针对某GDI发动机的多种设计方案,利用CFD手段模拟了缸内的流动、喷雾、点火燃烧等过程,对流动和燃烧情况进行评估,给出了设计方案的优化选择建议。
To choose the best one from several design schemes, CFD method was used to simulate the flow, injection, combustion process of a GDI engine that was in development. Evaluations about in-cylinder tumble and combustion were done, some advises were given for port de- sign, injector chosen and timing optimization.
