Abstract

This paper presents a research on the influence of exhaust gas recirculation (EGR) on performance and emissions of direct injection diesel engine VIKYNO RV125-2 using three-dimensional CFD code KIVA-3V. In this study, the engine runs at 2400 rpm, 80% nominal load, and EGR concentration is changed from 0% to 40%. Research results indicate that with 20% EGR, the engine power is reduced 3,16%, while the concentrations of both NOx and soot are reduced 12,11% and 67,1%, respectively.
