A closed loop control system for an exhaust gas recovery flow in an internal combustion engine having an intake air pressurizing device is provided. The closed loop control system includes an engine controller connected to an intake air mass flow sensor, an engine operation sensor, and an intake air throttle valve for controlling the intake air mass flow rate. In addition, the controller is operatively connected to a variable gas pocket valve for selectively controlling exhaust gas feedback in conjunction with the intake air throttle valve. The variable gas pocket valve and the intake air throttle valve may be actuated in response to the control system parameters to provide accurate control of exhaust gas recovery flow to provide reduced emissions of unburned fuel and particulate matter from the engine.
