Abstract
An exhaust gas recirculation system includes a combustion chamber having at least one intake port in communication with the combustion chamber and a corresponding intake valve for controlling a flow through the intake port into the combustion chamber. The combustion chamber also has at least one exhaust port in communication with the combustion chamber and a corresponding exhaust valve for controlling a flow through the exhaust port from the combustion chamber. In addition, the combustion chamber has at least one exhaust gas recirculation port in communication with the combustion chamber and with the exhaust port external or adjacent to the combustion chamber. The exhaust gas recirculation port has a corresponding exhaust gas recirculation valve for controlling a flow through the exhaust gas recirculation port into the combustion chamber. The exhaust gas recirculation valve may be separately actuatable from the intake valve and the exhaust valve.
