An Exhaust Gas Recirculation (EGR) 23538844 valve reduces harmful nitrogen oxide (NOx) emissions by recirculating a portion of the engine’s exhaust gases back into the intake manifold. This lowers combustion temperatures, improving emissions and engine efficiency. It is controlled electronically or by vacuum and is essential for meeting environmental regulations.
