What Does EGR Stand For?

EGR stands for Exhaust Gas Recirculation

Exhaust Gas Recirculation (EGR) is an emissions control technology used in internal combustion engines to reduce nitrogen oxide (NOx) emissions. This process involves recirculating a portion of the engine's exhaust gases back into the intake manifold, thereby lowering the combustion temperature and inhibiting the formation of NOx. EGR systems contribute to improved air quality and compliance with environmental regulations, while also enhancing engine efficiency and performance under certain operating conditions.
