Abstract
An exhaust gas recirculation pump is used to pump exhaust gas from an exhaust manifold to the intake manifold of an engine. The recirculation pump is hydraulically actuated. The compressor stage of a turbocharger is hydraulically assisted by a hydraulically-driven turbine mechanically connected to the turbocharger compressor stage to provide additional compressed intake airflow during transient engine conditions or during periods when the engine provides low exhaust energy to the gas-driven turbine section of the turbocharger.
