The EGR (Exhaust Gas Recirculation) valve in a car is an essential component of the engine’s emission control system. Its primary function is to reduce pollution by reducing the formation of harmful nitrogen oxides (NOx) in the engine’s exhaust gases. The EGR valve achieves this by recirculating a portion of the exhaust gas back into the engine’s intake manifold.

When the EGR valve is open, a small amount of exhaust gas is redirected from the exhaust system and reintroduced into the combustion chambers. This gas acts as an inert gas, effectively diluting the air and fuel mixture. By lowering the oxygen levels in the combustion chambers, the EGR valve reduces the peak combustion temperature, minimizing the formation of nitrogen oxides. Overall, the EGR valve plays a crucial role in improving fuel efficiency and reducing pollution emissions, making it an essential component in modern automotive engines.
