Exhaust gas recirculation (EGR) is effective for the reduction of NOx emission from internal combustion engines. Although there has been extensive experimental research on emission formation by the application of EGR, little has been devoted to the diesel combustion process. An attempt was made to study experimentally the combustion process at different EGR rates and engine loads. A heavy duty turbocharged diesel engine was used for the tests and a Iow pressure EGR concept was applied. Different EGR rates were obtained simply by the position of EGR control valve. Exhaust gases were analysed for emissions of NOx, CO, H C and soot. In-cylinder pressure t race s were measured and analysed. A one-zone combustion model was used to compute the rate of heat release from the experimental results. Several combustion parameters such as ignition delay, duration of pre-mixed and diffusion flame, combustion duration, etc., were determined and carefully studied, and basic correlation is presented and discussed in this paper.
