Abstract
An intake manifold assembly includes an exhaust gas recirculation system and an intake manifold. The exhaust gas recirculation system includes a venturi with a venturi body. The venturi body includes an upstream cylindrical portion, a convergent portion, a downstream cylindrical portion, and a divergent portion. The upstream cylindrical portion is in exhaust gas receiving communication with a cylinder of an internal combustion engine system and configured to receive the exhaust gas from the cylinder. The convergent portion is contiguous with the upstream cylindrical portion and in exhaust gas receiving communication with the upstream cylindrical portion. The downstream cylindrical portion is contiguous with the convergent portion, separated from the upstream cylindrical portion by the convergent portion, and in exhaust gas receiving communication with the convergent portion. The divergent portion is contiguous with the downstream cylindrical portion and separated from the convergent portion by the downstream cylindrical portion.
