Title:
排気ガス成分のための触媒の貯蔵部の充填を触媒の劣化に応じて制御する方法
Document Type and Number:
Japanese Patent JP7421896
Kind Code:
B2
Abstract:
A method is presented for regulating a filling of an exhaust gas component reservoir of a catalytic converter in the exhaust of an internal combustion engine. Using a first catalytic converter model, an actual fill level of the exhaust gas component reservoir is ascertained. An aging state of the catalytic converter is determined; and a set of model parameters of the first catalytic converter model is allocated to the aging state; the individual model parameters being ascertained by interpolation from basic values of model parameters, the basic values having been determined for at least two different aging states of a catalytic converter of identical design.
