EGR (Exhaust Gas Recirculation)

Exhaust Gas Recirculation (EGR) is a vehicle emission control technique that reduces nitrogen oxide (NOx) pollutants. It works by diverting a small amount of exhaust gases back into the engine’s intake air. These gases dilute the fresh air entering the engine, which helps lower combustion temperatures. Cooler combustion minimizes the formation of harmful NOx emissions. EGR systems improve environmental performance of engines while maintaining efficiency. Properly functioning EGR is essential for meeting emissions standards and maintaining engine health.
