...Jason A. Meyer; Stephen Yurkovich; Shawn Midlam-Mohler One of the most overlooked and oversimplified components of an engine model used for model based air-to-fuel ratio (AFR) control and/or diagnostics is the exhaust gas dynamics model. Without a proper model of the exhaust system, the mixing...
