SISTEMA DI MONITORAGGIO DELL'EFFICIENZA DI UN CATALIZZATORE, PARTICOLARMENTE PER AUTOVEICOLI

The efficiency of a catalyser (C) is evaluated starting from output signals (S7, S8) of two lambda probes (L1, L2) disposed upstream and downstream respectively of the catalyser (C). In particular, a signal obtained by calculating the difference between the time averages (V1, V2) obtained by integra...

Summary:The efficiency of a catalyser (C) is evaluated starting from output signals (S7, S8) of two lambda probes (L1, L2) disposed upstream and downstream respectively of the catalyser (C). In particular, a signal obtained by calculating the difference between the time averages (V1, V2) obtained by integration and subsequent division for the duration of an integration window of output signals (S7, S8) of these probes (L1,L2) is used as the signal indicative of efficiency.
