A single cylinder engine was modified into a photographic test equipment. A new method-filling and cycling nitrogen gas to the cylinder-was used to keep the fuel in combustion chamber out of firing.Tests were carried out at three fuel injection pressure and three gas swirl rates. The chamber swirl rate was measured by hot-wire anemometer, the fuel spray pictures were taken by a high speed camera.By reference to the experimental results, the spray bevaviers in swiling flow were discussed both in the main injection and the end injection periods.
