摘　　要：利用所研制的试验缸盖系统及进气道，研究了四气门柴油机四种单独气道及两种组合气道工作方式下进气道的流动特性。结果表明：四气门柴油机两进气道之间产生相互干扰，干扰的程度决定于各气道的自身结构、两气道形状的不同组合及两气道之间布置的相对位置。The author makes a set of experimental cylinder head.With this device,this paper makes an experimental study on induction flow characteristics in four-valve diesel engine on the condition of four kinds of single port engine and two kinds of combined port engine.The result manifests:The two ports of four-valve diesel engine interfere with each other.The interference between the two ports depends on each port structure itself,different combinations of two ports shapes and relative position between two ports.
