Introduction to EGR Valve
The Exhaust Gas Recirculation (EGR) valve is a critical component in modern automotive and industrial engines. Its main function is to redirect a portion of the engine’s exhaust gases back into the combustion chamber. By doing so, it helps to lower the combustion temperature, which in turn reduces the formation of nitrogen oxides (NOₓ), a major pollutant in vehicle emissions. This not only contributes to environmental protection by meeting strict emission standards but also improves fuel efficiency and engine performance in some cases. The EGR valve’s operation is carefully controlled by the engine control unit (ECU) to ensure optimal performance under various operating conditions. EGR Valve
