Abstract: An exhaust gas recirculation system includes an engine defining first and second combustion chambers, wherein a fuel is combustible to produce a combustion gas. The system includes an intake manifold disposed in fluid communication with the first and second chambers, an exhaust manifold disposed in fluid communication with the second chamber, and an exhaust gas recirculation conduit disposed in fluid communication with the first chamber and configured for directing the gas from only the first chamber to the intake manifold. The system includes a bypass valve transitionable between a first position wherein the conduit is disposed in fluid communication with the exhaust manifold such that the gas flows from the first chamber to the exhaust manifold, and a second position wherein the conduit is not disposed in fluid communication with the exhaust manifold such that the gas does not flow from the first chamber to the exhaust manifold.
