This report discusses the theoretical and experimental considerations and math model results used to establish a simplified engine-dynamometer test for catalytic converters. Simulation results have been correlated with the EPA Federal Test Procedure (CVS-1) parameters. Working curves are presented to allow the user to predict ultimate catalytic converter performance in grams/mile.
Statistical correlation coefficients show predicted values and actual CVS-1 values to be highly correlated. A linear regression analysis demonstrates that the “cycle simulation” procedure described provides an excellent one-to-one guide to EPA Federal Test results.
