Reduced exhaust pollutants: Introducing some exhaust gas into the intake manifold and back into the cylinder lowers combustion temperature, reducing nitrogen oxide emissions. Exhaust gas dilutes the air-fuel mixture, reducing combustion intensity, resulting in smoother operation. EGR is generally turned off during idling, acceleration, and high loads to prevent insufficient power and unstable idling., Manufacturer: changqishangmao1
