看一份文献，讲直喷发动机如何使油气混合，其中第一种方法是促使空气运动，里面有这样一段话：“The first approach is to energize the air to promote mixing. The air energizing method creates turbulence with swirl and swish. The angle of the air intake port through which the air enters the chamber imparts a swirl or swish to the inrushing air. The swish is created by how the angles of the piston crown recess force movement in the air as the upward piston movement compresses the air trapped within the chamber.”
请教大家，这段话中的Swish的中文术语是什么？原意是“嗖嗖发声/嗖嗖的声音”，但是用在这里，似乎不是这个意思，但是俺绞尽脑汁都想不出来……
谢谢！
