摘　　要：在稳流气道试验台上研究了 376四气门汽油机一进气门开、另一进气门全闭条件下的斜轴涡流特性 ,发现斜轴涡流倾角在进气过程初期很快跃升到近 90°,之后渐渐回落 ;在进气过程中期之后 ,其倾角稳定于 4 1°左右。In this paper,the characteristics of inclined swirl of a 4 valve engine was studied on steady flow rig with one inlet valve opening.It was found that the angle of inclined swirl approached sharply to near 90° in the early intake stroke and stabilized at about 41° in the late intake stroke.The results can offer theoretic basis for solving the problem of burn deterioration at lower engine speeds in 4 valve engines.
