OBD requirements
CETESB
ā OBD
- Phase 8 introduces new requirements requiring a more robust system than the
previous phase,
- OBD will monitors the particulate matter filters, the Selective Catalyst Reduction
(SCR) system, including the reagent used for its operation (ARLA-32 urea solution),
oxidation catalyst and EGR (Exhaust Gas Recirculation), and other parameters;
- New requirements allow the reduction of specific limits used as threshold values for
indicating system malfunctions, also determined in the test cycles;
-
- The new requirements for OBD are also less susceptible to fraud;
- Fault code recording for 720 days opens the possibility to implement an I/M and a
market surveillance program in Brazil that uses OBD as one key component of in-use
operation performance verification.View entire presentation
