United States Patent Application

View the Complete Application at the US Patent & Trademark Office
An exhaust gas recirculation system comprises an exhaust driven turbocharger to deliver a compressed intake charge through an intake charge conduit and to an engine. A compressed intake charge cooler receives, cools and transits the compressed intake charge. A cooling system, independent of the engine cooling system delivers coolant to the compressed intake charge cooler to transfer heat from the compressed intake charge thereto and to a cooler. Exhaust gas conduits extend between the exhaust system of the internal combustion engine, from locations upstream and downstream of the exhaust driven turbocharger, to the intake charge conduit. Exhaust gas coolers receive, cool and transit the exhaust gas.
