摘要

Systems (100, 200 and 300) and methods (400, 500 and 600) for controlling exhaust gas emissions from naturally aspirated engine are disclosed. The system (100, 200 and 300) includes an open loop exhaust gas recirculation flow to the engine. The system (100, 200 and 300) includes a diesel oxidation catalyst (102, 202 and 302) mounted on or near exhaust manifold (106, 206 and 306) of the engine. Furthermore, the system (100 and 200) includes an exhaust gas mixing conduit (114 and 214) inserted into air intake conduit (104 and 204). The system (100, 200 and 300) further includes an exhaust gas recirculation valve (110, 210 and 310) mounted on cold side or a hot side of EGR cooler. Furthermore, the system (100, 210 and 310) includes an electronic control unit to control exhaust gas recirculation valve (110, 210 and 310) along with various other engine calibration parameters.
