  valve diesel engine
In-cylinder swirl formation process in a four-valve diesel engine
      
An experimental study is presented on the steady flow in a four-valve diesel engine rig by using hot-wire anemometry.
      
Through the analysis of the in-cylinder three-dimensional flow field of a four-valve diesel engine, the in-cylinder swirl formation process at various valve lift was investigated.
      


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.

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。

There are some different ways of arranging porting for the four-valve diesel engine, such as two helical intake ports, two tangential intake ports or one helical port and one tangential port etc. The helical intake port and the tangential intake port have different velocity distribution in cylinder, so the different inlet-port combination must result in the different airflow rate and the swirl ratio. This paper describes the results that the authors have investigated in the steady-flow rig.

气门柴油机进气道可以选用不同类型的进气道进行组合 ,如二个螺旋进气道、二个切向进气道或一个切向进气道一个螺旋进气道等。螺旋进气道和切向进气道气门出口处气流分布不同 ,不同的气道组合对进气流量和进气涡流影响必然不同。本文介绍了在气道稳流试验台上进行试验研究的结果。

On the steady flow test rig, the in- cylinder flow field underneath the bottom surface of 2 - valves and 4 - valves cylinder head models has been measured respectively by using the Hot Wire Anemometer and the in - cylinder air flow measurement system designed by ourselves. The formation pro- cess and different formation causes of the in - cylinder flow field from two diesel models have been analyzed in this paper.
