The introduction of more stringent standards for engine emissions requires a steady development of engine control strategies in combination with efforts to optimize in-cylinder combustion and exhaust gas aftertreatment. This study presents a simulation approach combining an engine and vehicle model. A well established 1D gas dynamics and engine simulation model is extended by five key features. These are models for (1) general species transport, in-cylinder (2) combustion and (3) pollutant formation, (4) catalytic pollutant conversion and (5) manifold wall wetting. The model is used to investigate the effect of retarded spark timing on engine out and tailpipe emissions during the first 60 seconds of a NEDC. The results lead to the conclusion that the applied simulation approach has the potential to reduce the experimental effort on a roller dynamometer in future.
