Abstract
An exhaust gas recirculation system for use with an internal combustion engine comprising a heat exchanger, a first turbocharger, and a generator. The first turbocharger provides compressed fresh air to an intake manifold. The heat exchanger cools the exhaust gas for recirculation into the intake manifold. The generator provides turbocharger control by imparting stored energy back into the turbocharger. Turbocharger control allows the exhaust gas recirculation system to operate more efficiently and over a wide range of operating conditions.
