The EGR (Exhaust Gas Recirculation) valve is a critical component in an engine's emissions control system. It recirculates a portion of the exhaust gases back into the combustion chamber, helping to lower combustion temperatures and reduce nitrogen oxide (NOx) emissions. By introducing exhaust gases, it also helps improve fuel efficiency and engine performance under certain conditions. Overall, the EGR valve plays a vital role in meeting environmental regulations and enhancing engine efficiency.
