Abstract:
An exhaust gas recirculation system for an internal combustion engine having a plurality of cylinders, each of the cylinders defining a combustion chamber and having an exhaust valve and an intake valve, said exhaust system comprising:exhaust manifold means for receiving exhaust gas from each of said cylinders through exhaust lines respectively connected to exhaust valves of said cylinders; and an exhaust flow control valve associated with at least one of said cylinders, said exhaust flow control valve controlling feed of a portion of the exhaust gas from each cycle of at least said one cylinder to another of the cylinders through an exhaust gas recirculation passage, bypassing said exhaust manifold, whereby an exhaust stroke of a piston within said one cylinder serves to pump exhaust gas through said exhaust flow control valve into said another cylinder; and wherein said exhaust line and said exhaust gas recirculation passage are joined through said exhaust flow control valve which diverts a portion of the exhaust gas received from said one cylinder to the exhaust gas recirculation passage.
