Abstract
The objective of this work is to investigate the effect of swirl and injection pressure on D.I. diesel combustion by using a transparent engine system. The test engine is equipped with common rail injection system to obtain high pressure and adjust injection timing and duration. In this study, the combustion analysis and steady flow test were conducted to obtain the heat release rate from in-cylinder pressure and the swirl ratio, respectively. In addition, the spray and diffusion flame images were investigated by a high speed camera. As the results, injection pressure was found to shorten ignition delay as well as enhance peak pressure and heat release rate at premixed combustion region. However, this effect was reduced in case of swirl flow. The swirl effect was found to shorten ignition delay at certain injection timing and generally enhance heat release rate
