exhaust gas recirculation

Exhaust Gas Recirculation (EGR) is a process used in engines to reduce emissions. It involves taking a small amount of exhaust gases, which are combustion byproducts, and recirculating them back into the engine’s intake. This lowers the amount of oxygen available for fuel combustion, reducing the formation of harmful nitrogen oxides (NOx). EGR helps engines run cleaner and meet environmental standards, while maintaining performance. It’s a controlled way to limit pollution without compromising the engine’s efficiency significantly.
