Abstract
An internal combustion engine comprises an intake system to deliver a compressed intake charge thereto. A venturi assembly is disposed in the intake system and defines a venturi defining a low pressure zone 'Z' for the intake charge passing therethrough. An annular exhaust gas recirculation conduit distribution passage extends circumferentially about an inlet annulus of an intake manifold and receives diverted exhaust gas from an exhaust system for delivery to the intake charge through exhaust gas recirculation diffuser passages disposed at circumferentially spaced locations about the annular exhaust gas recirculation conduit distribution passage.
