Results of an effort to integrate an aftertreatment system for the simultaneous reduction of NOx and PM emissions on a Tier 2 Evolution Locomotive are presented. The paper provides detail on the solution that was realized to meet packaging constraints and also highlights aftertreatment performance limitations that resulted from these design decisions. Analysis results showing the predicted impact on engine performance are presented and compared to results obtained from field testing of the integrated system.
