Abstract
Effects of exhaust gas recirculation (EGR) on particulate carbon and NOx emissions have been examined using a single-cylinder, divided-chamber diesel engine operating at several loads and speeds. For a fixed start-of-combustion timing, EGR reduced x emissions while simultaneously increasing particulate carbon emissions. Results of this study indicate that the effects of EGR on both of these pollutants could be explained by variations in the stoichiometric flame temperature (Tf), which is the characteristic temperature of a diffusion-controlled combustion process. These results are consistent with an earlier study in which O2 and N2 were added to the intake air of a diesel engine.Keywords
