What is the role of an EGR cooler in reducing emissions?
An Exhaust Gas Recirculation (EGR) cooler reduces nitrogen oxide (NOx) emissions by cooling the exhaust gases before they are recirculated into the engine’s intake manifold. Cooler exhaust gases lower the combustion temperature, which reduces the formation of NOx, a harmful pollutant. The EGR cooler is particularly effective in diesel engines, where NOx emissions are a significant concern. By reducing NOx emissions, the EGR cooler helps vehicles meet stringent environmental regulations and improve air quality.
