  "textContent": "The exhaust side control unit (7a) sets the dead-time of the exhaust system (E) successively and variably according to the flow of the exhaust gas fed to the catalytic device (3) and successively identifies the values of the parameters of the exhaust system (E) model. Having the dead-time elements of the set dead-time, the control unit successively calculates, by using the identified values of the parameters, a target air-fuel ratio (KCMD) so as to converge the output of the O2 sensor (6) to a target value. An engine side control unit (7b) controls the air-fuel ratio of the engine (1) according to the target air-fuel ratio (KCMD), and, in the algorithm for the identification processing of the parameters of the exhaust system (E) model, the values of weighed parameters are set variably according to the flow of the exhaust gas.",
