An apparatus for and method of obstructing an air intake flow ( ) improves the mixing and driving force when an EGR flow ( ) is introduced to the air intake flow ( ). Before the EGR flow ( ) enters a passage ( ) where it is intended to be mixed with an air flow ( ), the air flow ( ) is obstructed to enable better and faster mixing of the EGR flow ( ) with the air flow ( ). A pressure differential is created to increase suction of EGR flow ( ) into the intake air flow ( ), thereby resulting in increased EGR flow ( ) into the cylinders of an engine.

Obstruction of flow to improve flow mix

There is provided an intake manifold module that integrates an intake air manifold with an exhaust gas recirculation system resulting in a compact design that optimizes vehicle engine compartment space, and results in reduced engine manufacturing time and cost. The intake manifold module comprises an integrally cast intake air manifold having an EGR valve aperture, an EGR cooler mounting, an EGR gas-out passage, and an EGR coolant-out; an EGR valve operatively mounted in the EGR valve aperture, and an EGR cooler cooperatively attached to the intake air manifold. Further, the EGR cooler comprises a gas outlet attached to the EGR gas-out passage, an exhaust gas inlet, a coolant inlet passage, a coolant outlet attached to the EGR coolant-out passage, and an EGR cooler mounting bracket. In operation, exhaust gases enter the EGR cooler, are cooled by EGR coolant, pass through the EGR valve and into the intake manifold.
