The EGR air flow control valve is located between the incoming charge air and the intake manifold. It is used to increase the EGR flow rate at low engine loads. The valve is never totally closed, but the valve position depends on the exhaust gas quantity that needs to be recirculated with in the emission target. See Fig 1.
