A comparison of different catalyst preparation methodologies for EOBD monitoring 2001-24-0063

Since 2000 the European regulation has introduced an ""on-board"" diagnosis system on the emission relevant components (EOBD). In particular, a monitoring of the catalytic converter has been introduced and the damage recognition threshold has been fixed for THC emissions only (0.4 g/km for EURO stage 3, evaluated on NEDC cycle). Therefore, special damaged components with THC emissions greater then the threshold limit is needed during calibration and tuning phases.
