To reduce NOx emissions, all vehicles are equipped with an Exhaust Gas Recirculation (EGR) system. The EGR system recirculates exhaust gases from an exhaust port in the cylinder head to a port in the intake manifold located below the carburetor. EGR flow is controlled by the EGR valve, thermo valve, EGR solenoid valve (turbocharged models), or vacuum regulator valve (carbureted models).
