  • Recirculation of exhaust gas condensate
    Patent number: 8015809
    Abstract: Systems for operating on an internal combustion engine coupled to an exhaust conduit and an intake conduit include an exhaust gas recirculation conduit in fluid communication with the exhaust conduit, a heat exchanger coupled to the exhaust gas recirculation conduit to cool at least a portion of the amount of exhaust, a liquid accumulator adapted to accumulate liquid from at least a portion of the amount of exhaust, and a condensate conduit coupled to the liquid accumulator. Methods of operating an engine include: receiving an exhaust gas recirculation stream from a main exhaust stream, cooling the exhaust gas recirculation stream, removing at least some condensate from the exhaust gas recirculation stream after cooling, and adding at least some of the condensate removed from the exhaust gas recirculation stream to the main exhaust stream and/or to an inlet charge of the engine.
