Summary:

A transient one-dimensional model developed to simulate the thermal and conversion characteristics of adiabatic monolithic converters operating under warm-up conditions is presented. The model takes into account the gas-solid heat and mass transfer, axial heat, conduction, chemical reactions and the related heat release.The model has been used to analyze the transient response of an axisymmetric catalytic converter during a warm-up as a function of catalyst design parameters and operating conditions in order to observe their effects on the lightoff behaviour.The experimental test was carried out in two steps: the first on a sample for lightoff test and the second on two-stroke 150 cc engine with Pt/Rh metal-supported catalyst and full open-throttle condition. The simulated temperatures are close to test results. The predicted conversion efficiencies are qualitatively acceptable
