Abstract:
1. A system to manage exhaust gas expelled from cylinders of an internal combustion engine, the system comprising: an intake system including an exhaust gas recirculation apparatus to distribute recirculated exhaust gas in an air stream to for an internal combustion engine statically without any moving structure; the apparatus having a first inlet to receive ambient air, a second inlet to receive recirculated exhaust gas, and an outlet to provide a mixture of the air and the recirculated exhaust gas, the air-exhaust gas mixture to be provided to the internal combustion engine through an intake manifold; an intake passage between the first inlet and the outlet; an exhaust gas chamber to receive the recirculated exhaust gas from the second inlet, wherein the exhaust gas chamber has a longitudinal length extending along a longitudinal length of the intake passage; the exhaust gas chamber separated from the intake passage by a wall structure of the apparatus, wherein the exhaust gas chamber is in fluid communication with the intake passage by a plurality of apertures arranged on the wall structure; wherein the plurality of apertures are configured to distribute the recirculated exhaust gas radially into the intake passage from the exhaust gas chamber along the longitudinal length of the intake passage; and wherein the plurality of apertures are arranged in a pattern which compensates for a drop in recirculated exhaust gas pressure along the longitudinal length of the exhaust gas chamber.
