Exhaust gas recirculation (EGR) is a system that takes exhaust gas from a dieselâs exhaust manifold and reintroduces it into the intake of the engine to reduce the combustion chamber temperature.
EGR is a very useful technique for reducing the NOx emission. In the present research, experimental investigations were conducted to study the effect of EGR on performance and emissions of a diesel engine. EGR displaces oxygen in the intake air by exhaust gas re-circulated to the combustion chamber.
