EXHAUST GAS RECIRCULATOR MIXER

摘要

The present invention provides an exhaust gas recirculation mixer (150) for use with a long route (i.e., low pressure) EGR system adapted for use in a turbocharged internal combustion engine. (100) The mixer comprises an outer wall (206) and an inner wall (208) defining a cavity (204) therebetween, a chamber (214) defined within the inner wall, an exhaust gas inlet on the outer wall, and apertures (281-285) of varying dimensions disposed within the inner wall so that exhaust gas enters the mixer in a controlled flow through the exhaust gas inlet, through the cavity, and through the apertures into the chamber for mixture with ambient air.
