Abstract
An improved exhaust gas recirculation (EGR) system comprises combustion chambers divided into a first portion and a second portion. An intake valve and an exhaust valve are associated with each combustion chamber. An intake manifold is in fluid communication with the combustion chambers through respective intake valves. A first exhaust manifold is in fluid communication with said first portion of combustion chambers through respective exhaust valves. A second exhaust manifold is in fluid communication with said second portion of combustion chambers through respective exhaust valves. An EGR exhaust valve is associated with each combustion chamber in said second portion. An EGR manifold is in fluid communication with each combustion chamber in said second portion through respective EGR exhaust valves and with said at least one intake manifold.
