Device for mixing intake air flow with recirculated exhaust gas flow in internal combustion engine of e.g. diesel type motor vehicle, has mixing plate integrated to air duct and comprising downstream edge located upstream of axis of pipe

摘要

The device has a supply pipe (2) for supplying burnt gas (10) to an air duct (1), where an axis (z) of the supply pipe crosses an axis (x) of the air duct. A mixing plate (4) is integrated to the air duct, and is symmetric with respect to a plane defined by the axes of the duct and the supply pipe. A downstream edge (6) of the mixing plate is located upstream of the axis of the supply pipe, where the downstream edge of the mixing plate comprises a notch having a shape corresponding to contour of an end (3) of the supply pipe.
