OBSTRUCTION OF FLOW TO IMPROVE FLOW MIX

摘要

An apparatus for and method of obstructing an air intake flow (115) improves the mixing and driving force when an EGR flow (111) is introduced to the air intake flow (115). Before the EGR flow (111) enters a passage (113) where it is intended to be mixed with an air flow (115), the air flow (115) is obstructed to enable better and faster mixing of the EGR flow (111) with the air flow (115). A pressure differential is created to increase suction of EGR flow (111) into the intake air flow (115), thereby resulting in increased EGR flow (111) into the cylinders of an engine.
