The main works done in this thesis are as follows:(1) The transient temperature field of air in swirl chamber is measured by means of Laser-Moire-Deflectometry for the first time.

主要内容有：(1)我们首次利用激光莫尔偏折法对涡流室介质温度场进行了实机测量在分析测试结果的基础上发展了相应的数学模型。

A mathematics Model describing the temperature field is developed.(2) Air flow in swirl chamber is measured and studied by means of LDA for the first time.

2我们首次利用激光多普勒测速仪对涡流室内空气运动进行了测试和分析，对原有的数学模型作了进一步的完善和发展。

Through the analysis of different cross section flow field in cylinder of two-valve and four-valve diesel engine, the following conclusion can be obtained: The formation of intake swirl of two-valve diesel engine mainly is effected by an intense air flow ring zone near the radius from valve axis to cylinder axis, as the flow progresses down through the cylinder, the ring zone air flow expends to both side and finally forms an unified rigid rotating swirl motion.

2号缸盖的螺旋进气道产生的绕自身气门轴线的动量矩比1号缸盖的大，且切向气道的径向速度在前峰面上的数值比1号缸盖的速度数值大很多，因此，两进气道组合后的动量矩损失也大，所以虽然2号缸盖的两个进气道单独的涡流比都高于1号缸盖的两个进气道，但组合后的合成涡流比却是基本相同的。

The data of atomizing mass flow, atomizing angle and atomizing droplet size of the pressure - swirl atomizer has been obtained by making an experiment on the pressure - swirl atomizers with different tangential orifice diameter and tangential orifice total area.

本文对小流量离心式喷嘴雾化特性及其影响因素进行了实验研究，着重研究了其他研究者很少涉及的切向孔总面积对离心式喷嘴雾化特性的影响，并对离心式喷嘴燃料分布特性进行了研究。

For example, it may prove difficult to cope with the in-furnace aerodynamic characteristics resulting from the use of a swirl burner on the arch-crown of the W-shaped boiler. In such a case one will not only be deprived of the advantages attributed to the use of the swirl burner but also suffer from a multitude of troublesome issues.

但采用旋流燃烧器后，由于W型锅炉燃烧的特殊性，给锅炉的设计和运行带来了新的情况，如对旋流燃烧器在W型锅炉拱顶采用旋流燃烧器后炉内的空气动力特性不能很好得到掌握，不但得不到旋流燃烧器所带来的优点，还会引起很多问题。

When the swirl variable device is part-opened, because swirl has some effect on the second injection, second injection timing has distinctly effect on fuel consumption, and the fuel consumption change fluctuantly with twice injection timing. When the tumble variable device is adopted, second injection timing also has effect on fuel consumption, but there is only one point that the fuel consumption is lowest. When the load is bigger, the second injection point where the fuel consumption is lowest is earlier than the smaller load.

在可变涡流结构中，当阀片处于非全开状态时，由于涡流运动对二次喷油的作用，二次喷油正时对发动机的比油耗存在明显影响，发动机比油耗随喷油正时改变呈较明显的波动状；在可变滚流结构中，二次喷油正时对发动机比油耗同样存在影响，但最低油耗点只有一个，当负荷较大时，最低比油耗所对应的喷油正时要更早一些。

The effect of swirl on THC emission is not obvious if the swirl variation range is not too big.

柴油机气缸内涡流水平的适度改变，不会引起THC排放的明显变化。

In order to understand the swirl system deeply,the three-dimensional particle dynamic analyzer was used to measure the velocities of the steady turbulent cold flows in the swirl three-branched modular junction located at the end of the exhaust system,and three-dimensional numerical simulation of the flows was carried out by use of the ALE algorithm.
