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.
The NOx emission benefit of EGR comes at a cost: other measures are usually required to avoid unacceptable increases in fuel consumption, emissions of PM, HC, and CO, engine wear and reductions in engine durability.
