Dedicated Exhaust Gas Recirculation Control Systems and Methods

An engine system includes: an internal combustion engine having a plurality of cylinders; a bypass valve arranged to receive exhaust output from at least a dedicated one of the cylinders and to selectively one of: direct the exhaust through an exhaust system to atmosphere; and direct the exhaust to an exhaust gas recirculation (EGR) valve; the EGR valve, where the EGR valve is configured to, when open, enable flow of the exhaust to an intake manifold of the internal combustion engine; and an intake air valve located between an air cleaner and a mass airflow (MAF) sensor and configured to, when open, enable flow of ambient air to the intake manifold.
