Abstract
An exhaust gas re-circulation (EGR) system is provided for use in conjunction with an internal combustion engine. The EGR system includes an intake manifold, an exhaust manifold, a passageway connected in flow communication between the exhaust manifold and the intake manifold, and an EGR valve interposed in the passageway for controlling re-circulation of exhaust gas into the intake manifold. In addition, an emissions control device (e.g., a catalytic converter) for reducing exhaust emissions in the gas flowing into the intake manifold is connected in flow communication with the EGR valve.
